Among them, stress injury is the main complication of prone spine surgery, but the reasons for stress injury in prone spine surgery are not clear, and whether prone cardiopulmonary resuscitation (CPR) can be used needs to be further verified. Supine cardiopulmonary resuscitation is commonly used in posterior spinal surgery, retroperitoneal surgery, and so on, which can effectively improve the patient’s hypoxemia. Such surgeries require a high level of anesthetic management, and cardiopulmonary resuscitation is necessary if a patient in a prone position experiences cardiac arrest. In the process of cardiopulmonary resuscitation, supine cardiopulmonary resuscitation is often used, especially for some obese patients, if they are immediately changed to the supine position, it takes up more time, there may be wound infection, and there is a possibility of missing the optimal rescue and resuscitation time. Based on this, this paper reviews the use of prone-position cardiopulmonary resuscitation for spinal surgery in the prone position.展开更多

Patients and Methods: This study retrospectively analyzed 130 patients, 90 men and 40 women, aged on average 48.7 ± 11.9 years (30 to 65) treated between 2018 and 2020 in the Orthopedics and trauma department at the Moulins-Yzeure hospital center, for olecranon fracture using the Medartis H-locked plate. The study aimed to evaluate the results of this surgical method, particularly with regard to postoperative complications. Results: Among the 130 patients, there were 90 men and 40 women, with an average age of 48.7 ± 11.9 years (30 to 65). 50% of all patients were aged over 51 years. The plate used was standard, the same for the 130 patients with the same operating technique. The left side was more affected at 53.8%, the dominant side was less affected at 46%;the majority of patients had been temporarily immobilized with a posterior cast splint before surgery. The average time between trauma and operation was 9 days with a minimum time of 1 day and a maximum of 30 days. At a maximum follow-up of 2 years postoperatively, all patients reported satisfactory results with a return to their previous activities within 60 days after surgery. Conclusion: Medartis H-locked plate osteosynthesis is a reliable solution for the surgical treatment of olecranon fractures.展开更多

The aim of our study was to report our experience in the management of open fractures by firearms and monitoring with a decline of 6 months the lesions observed in peacetime. This retrospective study over 3 years (January 2007-November 2010), supplemented by a prospective (December 2010-November 2011) is based on an analysis of operative reports and clinical records of patients admitted to the Yaoundé Central Hospital. 29 cases were selected, including 35 lesions were observed. Our series consists of 27 men and 2 women, mean age 30 years. 40% of our patients were initially supported (debridement) before the 6th hour and 51.42% between the 6th and 24th hours. In terms of internal fixation, these figures were 66% between the 25th and 96th hours. The type of material was used as the external fixate (64.9%). Conversion processing by the establishment of an internal hardware, after 3 - 6 weeks and control NFS (numeration of blood count or blood count), VS (rate of sedimentation), CRP (C reactive protein). Unfortunately this has been possible only in two cases because of financial means. In 40% of cases, surgical outcome was simple, and complications to a type of osteomyelitis, shortening, suppuration in 42.7% of cases.展开更多

Methods: Seventy-eight patients with thoracolumbar burst fractures were retrospectively reviewed to calculate the stenotic ratio of spinal canal based on the midsagittal diameters and the hyphosis angle according to Cobb. The ASIA scoring of motor function of lower extremities was recorded . Results: The differences (P > 0.05) of the stenotic ratio of spinal canal and the kyphosis angle were not significant between patients without neurological deficit, with incomplete and complete lesions. No significant correlation(P > 0.05) between the stenotic ratio of spinal canal and the kyphosis angle, and ASIA scoring was noted. Conclusion:The severity of spinal cord injuries in thoracolumbar burst fractures is not predicted according to the percentage of canal stenosis or the degree of kyphesis induced by thoracolumbar burst fractures.展开更多

In our context, very few studies have been performed comparing the clinical effectiveness of unilateral versus bilateral fixation in the surgical management of lumbar spinal canal stenosis. Objective: Evaluate the impact on quality of life and clinical efficacy of unilateral spondylodesis compared to bilateral spondylodesis in the surgical management of lumbar spinal canal stenosis at the Yaounde Central Hospital. Methods: This was a retrospective descriptive cross-sectional study for a period of 4 years, from June 2015 to June 2019. It involved all patients operated for lumbar canal stenosis and who underwent spondylodesis or spinal fusion at the neurosurgery department of the Yaounde Central Hospital. Results: A total of 68 participants were recruited during our study period. 32 (47%) of the study population were in the 50 - 60 age group, with a mean age of 56.98 years ranging from 41 to 75 years. Females, housewives and farmers were the most affected. In our study, 72% of patients had unilateral spondylodesis and 28% had bilateral fusion. Preoperatively, 71% of patients had insurmountable pain, refractory to medical treatment. At 3 months postoperatively, 73.7% of patients with bilateral setup had moderate pain compared to 69% of those with unilateral setup. At 6 months postoperatively, 79% of patients with bilateral fusion had mild pain compared to 82% of patients with unilateral setup. At 1 year postoperatively, all patients had mild pain. Preoperatively, 66.2% of patients were unable to walk and 19.1% of patients were bedridden according to the Oswestry score. At 3 months postoperatively, 10.2% of patients with unilateral setup were unable to walk compared to 10.5% of patients with bilateral fixation, while 67.3% of patients with unilateral fixation had moderate disability compared to 52.6% of patients with bilateral fixation. At 6 months postoperatively, 51% of patients with unilateral setup had moderate disability compared to 47.4% of patients with bilateral fixation, while 42.9% of patients with unilateral fixation had mild disability compared to 42.1% of patients with bilateral fixation. At 1 year postoperatively, 81.6% of patients who underwent unilateral fixation had only mild disability compared to 73.7% of patients with bilateral fixation. Conclusion: The assessment of quality of life according to the set-up used shows similar results at 3 months, 6 months and 1 year, with no statistically significant differences. Single-sided pedicle screw fixation combined with transforaminal lumbar interbody fusion or mounting has the advantage of being faster, with less bleeding and is less expensive compared to bilateral fixation.展开更多

However some studies evidenced that early surgery doesn’t always have a beneficial effect on mortality and complications. Therefore further studies could be useful in order to better assess risk related factors of patients requiring surgical treatment for femoral neck fracture. The purpose of this study is to evaluate the effect of preoperative ASA score and timing of surgery on mortality, complications and clinical outcome. Methods: All 336 patients operated in our center from January 2013 to December 2014 were selected for this retrospective study. Patients were divided in three groups as follows: group 1 patients treated within 48 hours;group 2 patients treated between 48 to 96 hours;group 3 patients treated over 96 hours. The preoperative ASA score was recorded for each patient. Complication, clinical outcome and mortality at one-year follow-up were evaluated. At follow-up ambulation was graded as: confined to bed, assisted ambulation, and normal ambulation. Complications both local (infections, malunion, dislocation) and systemic (deep vein thrombosis, pulmonary embolism, lung infections, ischemic disorders of heart) were recorded as well as number of transfusions. Statistical analysis was performed with chi square test and P value Results: 308 patients’ data were fully available for this study. At one-year follow-up return to normal ambulation was higher for patients of group 1 as compared with group 2 and 3 and in group 2 as compared with group 3 (P = 0.04). There was no difference in mortality and return to ambulation between patients with ASA score 1 and 2 (P = 0.06);patients with ASA score ≥ 3 showed a statistically significant higher mortality (P = 0.004) and rate of complications (0.0008) regardless of timing of surgery. There was no statistically significance in blood transfusion among the three groups. Discussion and Conclusion: Clinical outcome, complications and mortality have been previously reported from many authors and most studies agreed that early surgical treatment is recommended regardless of age and preoperative status of the patient. The present study suggests that early surgical treatment is actually able to reduce mortality and complications and to improve clinical outcome in patients with better preoperative conditions, while for patients with ASA score ≥ 3 treatment within 48 hours seems not to prevent mortality and complications and improve clinical outcome.展开更多

Several established technologies are available and combined motor and somatosensory evoked potentials are considered mandatory for practical and successful IOM. Spinal cord evoked potentials are elicited compound potentials recorded over the spinal cord. Electrical stimulation is provoked on the dorsal spinal cord from an epidural electrode. Somatosensory evoked potentials assess the functional integrity of sensory pathways from the peripheral nerve through the dorsal column and to the sensory cortex. For identification of the physiological midline, the dorsal column mapping technique can be used. It is helpful for reducing the postoperative morbidity associated with dorsal column dysfunction when distortion of the normal spinal cord anatomy caused by an intramedullary cord lesion results in confusion in localizing the midline for the myelotomy. Motor evoked potentials(MEPs) consist of spinal, neurogenic and muscle MEPs. MEPs allow selective and specific assessment of the functional integrity of descending motor pathways, from the motor cortex to peripheral muscles. Spinal surgeons should understand the concept of the monitoring techniques and interpret monitoring records adequately to use IOM for the decision making during the surgery for safe surgery and a favorable surgical outcome.展开更多

This study adopted experimental devices, designed in-house, to construct standardized ventral and dorsal spinal cord injury animal models of 6 g and 17 g falling from a height of 2, 4, and 10 cm, and 15, 30 or 50 g transversal compression on the spinal cord. The results showed that gradual increases in the degree of histopathological injury led to decreased Tarlov and Basso, Beattie and Bresnahan scores for the behavioral test, and increased Ashworth scores for the hind limb. Furthermore, there was a gradual decline in the slope test in the rats with dorsal spinal cord injury that correlated to increases in the falling substance weight or falling height. Similar alterations were observed in the ventral spinal cord injured rats, proportional to the increase in compression weight. Our experimental findings indicate that the standardized experimental rat models of dorsal and ventral spinal cord injury are stable, reliable and reproducible.展开更多

文摘Objective:To observe the analgesic effect of combined spinal and epidural anesthesia on older patients undergoing hip fracture surgery.Method:One hundred and twenty elderly hip fracture surgery patients treated in our hospital from January 2021 to December 2022 were selected and randomly divided into two groups,with 60 cases in the experimental group and 60 in the control group.The experimental group was given combined spinal-epidural anesthesia intervention measures,while the control group was given epidural anesthesia intervention measures.The analgesic effect,tumor necrosis factor-alpha(TNF-α),C-reactive protein(CRP)levels,and other observation indicators were analyzed after anesthesia intervention.Result:After the intervention,the analgesic effect and the evaluation results of the subjects in the experimental group were better than those in the control group(P<0.05);the obtained values of TNF-αand CRP levels in the experimental group were higher than those of the control group(P<0.05).Conclusion:The combined spinal-epidural anesthesia intervention demonstrated positive outcomes.The analgesic effect of patients during surgery and their inflammatory factor levels improved,which makes this intervention worthy of clinical application and promotion.
文摘Spinal surgery is usually performed in the prone position, which is a longer and more difficult procedure and is prone to complications such as circulatory dysfunction and stress injuries. Among them, stress injury is the main complication of prone spine surgery, but the reasons for stress injury in prone spine surgery are not clear, and whether prone cardiopulmonary resuscitation (CPR) can be used needs to be further verified. Supine cardiopulmonary resuscitation is commonly used in posterior spinal surgery, retroperitoneal surgery, and so on, which can effectively improve the patient’s hypoxemia. Such surgeries require a high level of anesthetic management, and cardiopulmonary resuscitation is necessary if a patient in a prone position experiences cardiac arrest. In the process of cardiopulmonary resuscitation, supine cardiopulmonary resuscitation is often used, especially for some obese patients, if they are immediately changed to the supine position, it takes up more time, there may be wound infection, and there is a possibility of missing the optimal rescue and resuscitation time. Based on this, this paper reviews the use of prone-position cardiopulmonary resuscitation for spinal surgery in the prone position.
文摘Thoracic spine fracture is a common orthopedic injury that is usually caused by external forces acting directly on or transmitted to the thoracic spine through other parts of the spine.Thoracic spine fractures can be divided into two types:stable and unstable.An unstable fracture means that the relationship between the vertebral bodies is no longer stable,which may cause serious consequences such as spinal compression,nerve root compression,or spinal cord injury.Surgical treatment is often needed for patients with unstable fractures,nerve root compression,or spinal cord injury to restore stability and function to the thoracic spine.The probability of complications after thoracolumbar fracture surgery is high,which affects the outcome of surgical treatment.To improve postoperative rehabilitation outcomes,this article analyzed the value of nursing care based on the enhanced recovery after surgery(ERAS)concept for patients undergoing thoracolumbar fracture surgery.

文摘BACKGROUND Supracondylar humerus fractures account for more than 60%of all elbow fractures and about 1/5 of all pediatric fractures.Unfortunately,these fractures can be associated with risk of complications including neurovascular injuries,malunions and limb deformities.Controversy exists regarding the effect of time of surgical intervention and/or level of surgeon performing the surgery on outcome of these fractures.AIM To determine whether time of surgical intervention and/or surgeon level influence the outcomes of surgically managed pediatric supracondylar humerus fractures.METHODS We retrospectively studied 155 pediatric patients presenting with a supracondylar humerus fracture in a level 1 trauma center from January 2006 to December 2019.The data extracted included demographic data,fracture characteristics,surgical data,and follow-up outcomes.The collected data was analyzed and P values of<0.05 were considered statistically significant.RESULTS Of the cohort,11%of patients had documented post-operative complications,of which the majority occurred in surgeries performed after day time working hours and in fractures requiring open reduction.While the lowest complication rate was found in surgeries performed by pediatric orthopaedic surgeons,this did not reach statistical significance.CONCLUSION In pediatric patients undergoing surgery for supracondylar fractures,we found a higher complication rate when surgeries were not performed during working hours.Surgeon level and training had no significant effect on the risk of post-operative complications.
文摘BACKGROUND Thoracolumbar fractures are generally combined with spinal cord injury to varying degrees,which may cause deterioration of the patients’condition and increase the difficulty of clinical treatment.At present,anterior or combined anterior-posterior surgery is preferred for severe thoracolumbar fractures.AIM To investigate the effectiveness and postoperative rehabilitation of one-stage combined anterior-posterior surgery for severe thoracolumbar fractures with spinal cord injury.METHODS One-hundred-and-twenty patients who received surgery for severe thoracolumbar fractures with spinal cord injury at our hospital from February 2018 to February 2020 were randomly enrolled.They were randomly divided into group 1(one-stage combined anterior-posterior surgery,n=60)and group 2(onestage anterior-approach surgery,n=60).Treatment efficacy was compared between the two groups.RESULTS Blood loss was greater and the operation time was longer in group 1 than in group 2,and the differences were statistically significant(P<0.05).Incision length,intraoperative X-rays,and length of hospital stay were not significantly different between the two groups(P>0.05).Preoperative function of the affected vertebrae was not significantly different between the two groups(P>0.05).In each group,the patients showed significant improvement after surgery.The anterior vertebral height ratio and the posterior vertebral height ratio in group 1 after surgery were significantly higher than those in group 2.The Cobb angle after surgery was significantly lower in group 1 than in group 2(P<0.05).The canal-occupying ratio of the affected vertebrae was not significantly different between the two groups(P>0.05).Before surgery,there was no significant difference in the quality of life scores between the two groups(P>0.05).The above indicators were significantly improved after surgery compared with before surgery in each group.In addition,these indicators were markedly better in group 1 than in group 2 after surgery(P<0.05 for each).CONCLUSION One-stage combined anterior-posterior surgery effectively improves the function of the affected vertebrae and the life quality of patients with severe thoracolumbar fractures and spinal cord injury.This surgical approach is worthy of popularization in clinical use.
文摘BACKGROUND The combined anterior/posterior approach appears to be capable of reconstructing spinal stability,correcting thoracolumbar deformity,and promoting neural recovery in severe thoracolumbar fracture dislocation.However,this type of operation requires changing the body position during the procedure,resulting in a lengthy operation time.As a universal surgical robot,TINAVI robot has achieved good surgical results in clinical surgery.But to our knowledge,no reports describing TINAVI robot-assisted single lateral position anteroposterior surgery for thoracolumbar fracture dislocation.CASE SUMMARY We describe a case of a 16-year-old female patient with severe thoracolumbar fracture and dislocation underwent surgery assisted by the TINAVI robot.A onestage combined anterior and posterior operation was performed on a severe thoracolumbar fracture dislocation using the TINAVI robot,and the operation was completed in right lateral position.CONCLUSION The TINAVI robot-assisted one-stage anterior and posterior surgery in right lateral position for severe thoracolumbar fracture and dislocation is both safe and effective.
文摘The feasibility of three-dimensional (3D) printing technology cgmbined with minimally invasive surgery in the treatment of pubic rami fractures was explored.From August 2015 to October 2017,a series of 30 patients who underwent surgical stabilization of their anterior pelvic ring (all utilizing the 3D printing technology)by one surgeon at a single hospital were studied.The minimally invasive incisions were made through anterior inferior cilia spine and pubic nodule.Data collected included the operative duration,the blood loss,the damage of the important tissue,the biographic union and therecovery of the function after the operation.Measurements on inlet and outlet pelvic cardiograph were made immediately post-operation and at all follow-up clinic visits.The scores of reduction and function were measured during follow-up.Results showed that the wounds of 30 patients were healed in the first stage,and there was no injury of important structures such as blood vessels and nerves.According to the Matta criteria,excellent effectiveness was obtained in 22 cases and good in 8 cases.According to the functional evaluation criteria of Majeed,excellent effectiveness was obtained in 21 cases and good in 9 cases.It was suggested that the 3D printing technology assisted by minimally invasive surgery can better evaluate the pelvic fracture before operation,which was helpful in plate modeling, and can shorten surgery duration and reduce intraoperative blood loss and complications. The positioning accuracy was improved,and better surgical result was finally achieved.
文摘BACKGROUND Spinal osteoporosis is a prevalent health condition characterized by the thinning of bone tissues in the spine,increasing the risk of fractures.Given its high incidence,especially among older populations,it is critical to have accurate and effective predictive models for fracture risk.Traditionally,clinicians have relied on a combination of factors such as demographics,clinical attributes,and radiological characteristics to predict fracture risk in these patients.However,these models often lack precision and fail to include all potential risk factors.There is a need for a more comprehensive,statistically robust prediction model that can better identify high-risk individuals for early intervention.AIM To construct and validate a model for forecasting fracture risk in patients with spinal osteoporosis.METHODS The medical records of 80 patients with spinal osteoporosis who were diagnosed and treated between 2019 and 2022 were retrospectively examined.The patients were selected according to strict criteria and categorized into two groups:Those with fractures(n=40)and those without fractures(n=40).Demographics,clinical attributes,biochemical indicators,bone mineral density(BMD),and radiological characteristics were collected and compared.A logistic regression analysis was employed to create an osteoporotic fracture risk-prediction model.The area under the receiver operating characteristic curve(AUROC)was used to evaluate the model’s performance.RESULTS Factors significantly associated with fracture risk included age,sex,body mass index(BMI),smoking history,BMD,vertebral trabecular alterations,and prior vertebral fractures.The final risk-prediction model was developed using the formula:(logit[P]=-3.75+0.04×age-1.15×sex+0.02×BMI+0.83×smoking history+2.25×BMD-1.12×vertebral trabecular alterations+1.83×previous vertebral fractures).The AUROC of the model was 0.93(95%CI:0.88-0.96,P<0.001),indicating strong discriminatory capabilities.CONCLUSION The fracture risk-prediction model,utilizing accessible clinical,biochemical,and radiological information,offered a precise tool for the evaluation of fracture risk in patients with spinal osteoporosis.The model has potential in the identification of high-risk individuals for early intervention and the guidance of appropriate preventive actions to reduce the impact of osteoporosis-related fractures.

文摘BACKGROUND Intracranial hemorrhage after spinal surgery is a rare and devastating complication.AIM To investigate the economic burden,clinical characteristics,risk factors,and mechanisms of intracranial hemorrhage after spinal surgery.METHODS A retrospective cohort study was conducted from January 1,2015,to December 31,2022.Patients aged≥18 years,who had undergone spinal surgery were included.Intracranial hemorrhage patients were selected after spinal surgery during hospitalization.Based on the type of spinal surgery,patients with intracranial hemorrhage were randomly matched in a 1:5 ratio with control patients without intracranial hemorrhage.The patients'pre-,intra-,and post-operative data and clinical manifestations were recorded.RESULTS A total of 24472 patients underwent spinal surgery.Six patients(3 males and 3 females,average age 71.3 years)developed intracranial hemorrhage after posterior spinal fusion procedures,with an incidence of 0.025%(6/24472).The prevailing type of intracranial hemorrhage was cerebellar hemorrhage.Two patients had a poor clinical outcome.Based on the type of surgery,30 control patients were randomly matched in 1:5 ratio.The intracranial hemorrhage group showed significant differences compared with the control group with regard to age(71.33±7.45 years vs 58.39±8.07 years,P=0.001),previous history of cerebrovascular disease(50%vs 6.7%,P=0.024),spinal dura mater injury(50%vs 3.3%,P=0.010),hospital expenses(RMB 242119.1±87610.0 vs RMB 96290.7±32029.9,P=0.009),and discharge activity daily living score(40.00±25.88 vs 75.40±18.29,P=0.019).CONCLUSION The incidence of intracranial hemorrhage after spinal surgery was extremely low,with poor clinical outcomes.Patient age,previous stroke history,and dura mater damage were possible risk factors.It is suggested that spinal dura mater injury should be avoided during surgery in high-risk patients.
文摘Introduction: Olecranon fractures represent approximately 10% of upper limb fractures, orthopedic treatment is often doomed to failure and surgical treatment consists of fixing the fracture sites. Patients and Methods: This study retrospectively analyzed 130 patients, 90 men and 40 women, aged on average 48.7 ± 11.9 years (30 to 65) treated between 2018 and 2020 in the Orthopedics and trauma department at the Moulins-Yzeure hospital center, for olecranon fracture using the Medartis H-locked plate. The study aimed to evaluate the results of this surgical method, particularly with regard to postoperative complications. Results: Among the 130 patients, there were 90 men and 40 women, with an average age of 48.7 ± 11.9 years (30 to 65). 50% of all patients were aged over 51 years. The plate used was standard, the same for the 130 patients with the same operating technique. The left side was more affected at 53.8%, the dominant side was less affected at 46%;the majority of patients had been temporarily immobilized with a posterior cast splint before surgery. The average time between trauma and operation was 9 days with a minimum time of 1 day and a maximum of 30 days. At a maximum follow-up of 2 years postoperatively, all patients reported satisfactory results with a return to their previous activities within 60 days after surgery. Conclusion: Medartis H-locked plate osteosynthesis is a reliable solution for the surgical treatment of olecranon fractures.
文摘Fracture by firearms is a surgical emergency. The aim of our study was to report our experience in the management of open fractures by firearms and monitoring with a decline of 6 months the lesions observed in peacetime. This retrospective study over 3 years (January 2007-November 2010), supplemented by a prospective (December 2010-November 2011) is based on an analysis of operative reports and clinical records of patients admitted to the Yaoundé Central Hospital. 29 cases were selected, including 35 lesions were observed. Our series consists of 27 men and 2 women, mean age 30 years. 40% of our patients were initially supported (debridement) before the 6th hour and 51.42% between the 6th and 24th hours. In terms of internal fixation, these figures were 66% between the 25th and 96th hours. The type of material was used as the external fixate (64.9%). Conversion processing by the establishment of an internal hardware, after 3 - 6 weeks and control NFS (numeration of blood count or blood count), VS (rate of sedimentation), CRP (C reactive protein). Unfortunately this has been possible only in two cases because of financial means. In 40% of cases, surgical outcome was simple, and complications to a type of osteomyelitis, shortening, suppuration in 42.7% of cases.

文摘BACKGROUND Few reports have described lumbar foraminal stenosis-induced radiculopathy after treatment by full-endoscopic spine surgery(FESS)combined with percutaneous vertebroplasty(PVP)in patients with vertebral compression fractures.We herein report such a case,including the patient’s treatment process and doctor’s surgical experience.CASE SUMMARY A 79-year-old man presented with symptoms of radiculopathy after sustaining L4 vertebral compression fractures.Imaging and physical examination revealed L4 vertebral compression fractures combined with L3/4 Lumbar foraminal stenosis(LFS).The patient’s symptoms were low back pain with pain in the lateral left leg.Although many reports have described radiculopathy induced by osteoporotic vertebral compression fractures,the use of FESS combined with PVP has rarely been reported.This case report indicates that the combination of FESS and PVP is a safe and effective approach for the treatment of LFS-induced radiculopathy after vertebral compression fractures.This minimally invasive technique has great potential to replace traditional lumbar fixation and decompression surgery.Thus,we suggest the continued accumulation of similar cases to discuss the wider application of FESS.CONCLUSION For patients with osteoporotic vertebral compression fracture(OVCF)and LFS,PVP and FESS can be used to restore the vertebral height and reduce the pressure around the intervertebral foramen.Additionally,the combination of FESS and PVP can treat the pain or numbness of the low back and lower limbs and allow for recovery in a short time with excellent postoperative effects.In general,FESS is a good treatment for radiculopathy caused by foraminal stenosis after OVCF.
文摘BACKGROUND Hip fractures(HF)are common among the aging population,and surgery within 48 h is recommended.Patients can be hospitalized for surgery through different pathways,either trauma or medicine admitting services.AIM To compare management and outcomes among patients admitted through the trauma pathway(TP)vs medical pathway(MP).METHODS This Institutional Review Board-approved retrospective study included 2094 patients with proximal femur fractures(AO/Orthopedic Trauma Association Type 31)who underwent surgery at a level 1 trauma center between 2016-2021.There were 69 patients admitted through the TP and 2025 admitted through the MP.To ensure comparability between groups,66 of the 2025 MP patients were propensity matched to 66 TP patients by age,sex,HF type,HF surgery,and American Society of Anesthesiology score.The statistical analyses included multivariable analysis,group characteristics,and bivariate correlation comparisons with theχ^(2)test and t-test.RESULTS After propensity matching,the mean age in both groups was 75-years-old,62%of both groups were females,the main HF type was intertrochanteric(TP 52%vs MP 62%),open reduction internal fixation was the most common surgery(TP 68%vs MP 71%),and the mean American Society of Anesthesiology score was 2.8 for TP and 2.7 for MP.The majority of patients in TP and MP(71%vs 74%)were geriatric(≥65-years-old).Falls were the main mechanism of injury in both groups(77%vs 97%,P=0.001).There were no significant differences in pre-surgery anticoagulation use(49%vs 41%),admission day of the week,or insurance status.The incidence of comorbidities was equal(94%for both)with cardiac comorbidities being dominant in both groups(71%vs 73%).The number of preoperative consultations was similar for TP and MP,with the most common consultation being cardiology in both(44%and 36%).HF displacement occurred more among TP patients(76%vs 39%,P=0.000).Time to surgery was not statistically different(23 h in both),but length of surgery was significantly longer for TP(59 min vs 41 min,P=0.000).Intensive care unit and hospital length of stay were not statistically different(5 d vs 8 d and 6 d for both).There were no statistical differences in discharge disposition and mortality(3%vs 0%).CONCLUSION There were no differences in outcomes of surgeries between admission through TP vs MP.The focus should be on the patient’s health condition and on prompt surgical intervention.
文摘Objective:To evaluate the clinical effect of kyphoplasty in the treatment of multiple osteoporotic vertebral fractures in the elderly.Methods:The duration of the study was selected from January 2018 to December 2020,and 38 patients with multiple osteoporotic spinal fractures were selected for study evaluation.All patients were treated with kyphoplasty.The clinical indicators of the two groups were compared and analyzed.Results:The total effective rate was 94.7%and the complication rate was 5.3%.The height of midline,anterior and posterior vertebral body,Cobb angle,VAS score,ODI score and ADL score of 38 patients before and after treatment were compared,which were significantly better than those before treatment(P<0.05).Conclusion:The clinical effect of kyphoplasty in the treatment of elderly patients with multiple osteoporosis is significant,which can be promoted in all levels of medical institutions.
文摘Objective:To investigate the relationship between morphological abnormalities and spinal cord deficit in thoracolumbar burst fractures. Methods: Seventy-eight patients with thoracolumbar burst fractures were retrospectively reviewed to calculate the stenotic ratio of spinal canal based on the midsagittal diameters and the hyphosis angle according to Cobb. The ASIA scoring of motor function of lower extremities was recorded . Results: The differences (P > 0.05) of the stenotic ratio of spinal canal and the kyphosis angle were not significant between patients without neurological deficit, with incomplete and complete lesions. No significant correlation(P > 0.05) between the stenotic ratio of spinal canal and the kyphosis angle, and ASIA scoring was noted. Conclusion:The severity of spinal cord injuries in thoracolumbar burst fractures is not predicted according to the percentage of canal stenosis or the degree of kyphesis induced by thoracolumbar burst fractures.
文摘Introduction: The choice of adopting unilateral pedicle screw fixation or using bilateral pedicle screw fixation in lumbar spinal stenosis remains controversial. In our context, very few studies have been performed comparing the clinical effectiveness of unilateral versus bilateral fixation in the surgical management of lumbar spinal canal stenosis. Objective: Evaluate the impact on quality of life and clinical efficacy of unilateral spondylodesis compared to bilateral spondylodesis in the surgical management of lumbar spinal canal stenosis at the Yaounde Central Hospital. Methods: This was a retrospective descriptive cross-sectional study for a period of 4 years, from June 2015 to June 2019. It involved all patients operated for lumbar canal stenosis and who underwent spondylodesis or spinal fusion at the neurosurgery department of the Yaounde Central Hospital. Results: A total of 68 participants were recruited during our study period. 32 (47%) of the study population were in the 50 - 60 age group, with a mean age of 56.98 years ranging from 41 to 75 years. Females, housewives and farmers were the most affected. In our study, 72% of patients had unilateral spondylodesis and 28% had bilateral fusion. Preoperatively, 71% of patients had insurmountable pain, refractory to medical treatment. At 3 months postoperatively, 73.7% of patients with bilateral setup had moderate pain compared to 69% of those with unilateral setup. At 6 months postoperatively, 79% of patients with bilateral fusion had mild pain compared to 82% of patients with unilateral setup. At 1 year postoperatively, all patients had mild pain. Preoperatively, 66.2% of patients were unable to walk and 19.1% of patients were bedridden according to the Oswestry score. At 3 months postoperatively, 10.2% of patients with unilateral setup were unable to walk compared to 10.5% of patients with bilateral fixation, while 67.3% of patients with unilateral fixation had moderate disability compared to 52.6% of patients with bilateral fixation. At 6 months postoperatively, 51% of patients with unilateral setup had moderate disability compared to 47.4% of patients with bilateral fixation, while 42.9% of patients with unilateral fixation had mild disability compared to 42.1% of patients with bilateral fixation. At 1 year postoperatively, 81.6% of patients who underwent unilateral fixation had only mild disability compared to 73.7% of patients with bilateral fixation. Conclusion: The assessment of quality of life according to the set-up used shows similar results at 3 months, 6 months and 1 year, with no statistically significant differences. Single-sided pedicle screw fixation combined with transforaminal lumbar interbody fusion or mounting has the advantage of being faster, with less bleeding and is less expensive compared to bilateral fixation.
文摘Introduction: Early surgical treatment (within 48 hours) has been recommended for femoral neck fractures in order to avoid complications and reduce mortality rate, regardless of presence and severity of comorbidity and preoperative status (ASA score). However some studies evidenced that early surgery doesn’t always have a beneficial effect on mortality and complications. Therefore further studies could be useful in order to better assess risk related factors of patients requiring surgical treatment for femoral neck fracture. The purpose of this study is to evaluate the effect of preoperative ASA score and timing of surgery on mortality, complications and clinical outcome. Methods: All 336 patients operated in our center from January 2013 to December 2014 were selected for this retrospective study. Patients were divided in three groups as follows: group 1 patients treated within 48 hours;group 2 patients treated between 48 to 96 hours;group 3 patients treated over 96 hours. The preoperative ASA score was recorded for each patient. Complication, clinical outcome and mortality at one-year follow-up were evaluated. At follow-up ambulation was graded as: confined to bed, assisted ambulation, and normal ambulation. Complications both local (infections, malunion, dislocation) and systemic (deep vein thrombosis, pulmonary embolism, lung infections, ischemic disorders of heart) were recorded as well as number of transfusions. Statistical analysis was performed with chi square test and P value Results: 308 patients’ data were fully available for this study. At one-year follow-up return to normal ambulation was higher for patients of group 1 as compared with group 2 and 3 and in group 2 as compared with group 3 (P = 0.04). There was no difference in mortality and return to ambulation between patients with ASA score 1 and 2 (P = 0.06);patients with ASA score ≥ 3 showed a statistically significant higher mortality (P = 0.004) and rate of complications (0.0008) regardless of timing of surgery. There was no statistically significance in blood transfusion among the three groups. Discussion and Conclusion: Clinical outcome, complications and mortality have been previously reported from many authors and most studies agreed that early surgical treatment is recommended regardless of age and preoperative status of the patient. The present study suggests that early surgical treatment is actually able to reduce mortality and complications and to improve clinical outcome in patients with better preoperative conditions, while for patients with ASA score ≥ 3 treatment within 48 hours seems not to prevent mortality and complications and improve clinical outcome.
文摘Objective To explore the relevant risk factors of tramatic arthritis resulting from the surgery of acetabular fractures. Methods From January 2000 to January 2009,88 patients aged from 20 to 60 years old with acetabular fractures
文摘Recently, many surgeons have been using intraoperative neurophysiological monitoring(IOM) in spinal surgery to reduce the incidence of postoperative neurological complications, including level of the spinal cord, cauda equina and nerve root. Several established technologies are available and combined motor and somatosensory evoked potentials are considered mandatory for practical and successful IOM. Spinal cord evoked potentials are elicited compound potentials recorded over the spinal cord. Electrical stimulation is provoked on the dorsal spinal cord from an epidural electrode. Somatosensory evoked potentials assess the functional integrity of sensory pathways from the peripheral nerve through the dorsal column and to the sensory cortex. For identification of the physiological midline, the dorsal column mapping technique can be used. It is helpful for reducing the postoperative morbidity associated with dorsal column dysfunction when distortion of the normal spinal cord anatomy caused by an intramedullary cord lesion results in confusion in localizing the midline for the myelotomy. Motor evoked potentials(MEPs) consist of spinal, neurogenic and muscle MEPs. MEPs allow selective and specific assessment of the functional integrity of descending motor pathways, from the motor cortex to peripheral muscles. Spinal surgeons should understand the concept of the monitoring techniques and interpret monitoring records adequately to use IOM for the decision making during the surgery for safe surgery and a favorable surgical outcome.

文摘The duplication of animal models plays a key role in spinal cord injury research; however, there has been limited study into normal, external force-derived fracture dislocation. This study adopted experimental devices, designed in-house, to construct standardized ventral and dorsal spinal cord injury animal models of 6 g and 17 g falling from a height of 2, 4, and 10 cm, and 15, 30 or 50 g transversal compression on the spinal cord. The results showed that gradual increases in the degree of histopathological injury led to decreased Tarlov and Basso, Beattie and Bresnahan scores for the behavioral test, and increased Ashworth scores for the hind limb. Furthermore, there was a gradual decline in the slope test in the rats with dorsal spinal cord injury that correlated to increases in the falling substance weight or falling height. Similar alterations were observed in the ventral spinal cord injured rats, proportional to the increase in compression weight. Our experimental findings indicate that the standardized experimental rat models of dorsal and ventral spinal cord injury are stable, reliable and reproducible.
