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

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

Methods.Eighteen patients with spinal fracture dislocation were neurologically intact at the time of injury, and all were treated operatively. The fracture sites were:8 cases in cervical spine, 3 cases in thoracic spine, and 7 cases in lumbar spine. Eight patients with cervical injuries had variant degrees of forward slide and kyphotic deformity. Of the 10 thoracic and lumbar fractures, one had lateral dislocation, 4 cases with kyphotic deformities, 5 cases with spinal canal compromise averaged 50% (ranging from 40% to 70%). Results.The average period of follow up was 4.4 years with a range of 11 months to 13 years. All the patients returned to full time work. No patient developed neurologic deterioration. Kyphotic deformity was corrected in the 4 cases, and no progressive kyphosis was noted. There was no operation related complication. The averaged post operative hospitalization time was 13 days. Conclusions. Despite the rare incidence of spinal fracture dislocation without neurologic deficits, we suggested that kind of fracture be considered unstable fracture because of its potential risk of delayed neurologic deterioration and kyphotic deformity, and be treated operatively to restore the sagittal alignment and the stability of the spine.展开更多

Seventy seven patients with thoracic spine fractures were retrospectively reviewed. Of these, there were 37 compression fractures, 34 fracture dislocations, 3 burst fractures and 3 burst dislocations. Twenty six patients had a complete lesion of the spinal cord, 14 sustained a neurologically incomplete injury, and 37 were neurologically intact. Fifty three patients were treated nonoperatively and 24 treated operatively. Results. All patients were followed up for 2~15 years. None of the 26 patients with a complete lesion recovered any significant function. Of 37 neurologically intact patients, 13 had local pain although all of them remained normal function. Two of 14 patients with incomplete paraplegia returned to normal, 7 recovered some function and 5 did not recovered. Conclusions. Because of the unique anatomy and biomechanics of the thoracic spine, the classification commonly applied to thoracolumbar fractures is not suitable for thoracic fractures. Fusion and instrumentation are indicated when the fractures are unstable, while patients with incomplete lesion of the spinal cord may be the candidates for supplemented decompression.展开更多

文摘Objective:To compare effect of intrathecal meperidine,tramadol,magnesium sulfate,and dexmedetomidine on the prevention of post-spinal anesthesia shivering and adverse events in hip fracture repair patients.Methods:In a randomized,double-blind trial,132 patients with American Society of Anesthesiology(ASA)ⅠandⅡspinal anesthesia who needed hip fracture surgery were enrolled.Patients were stratified into 4 intervention groups based on a randomized block pattern:meperidine,tramadol,magnesium sulfate,and dexmedetomidine.Hemodynamic parameters including blood pressure,heart rate,and oxygen saturation,as well as the severity of shivering,core body temperature,Ramsay sedation score,adverse events,meperidine consumption were recorded and compared.Results:There was no statistically significant difference in the normal hemodynamic parameters,temperature,duration of surgery,meperidine consumption,and adverse events such as dizziness,hypotension,nausea,and bradycardia among groups(P>0.05).Compared to other groups,severity of shivering was the lower in the dexmedetomidine group 6 and 8 h after surgery.The Ramsay sedation scores were higher in the dexmedetomidine and meperidine groups 4 h after surgery(P=0.020).Conclusion:Dexmedetomidine acts better than the other three adjuvants in reducing complications such as shivering.Overall,these four adjuvants are helpful to prevent postoperative shivering and could be put forward as promising local anesthetics in spinal anesthesia,based on anesthesiologists’discretion and patients’general conditions.Clinical registration:The study was approved by the Research and Ethics Committee at the Valiasr Hospital(Arak,Iran)with the clinical trial code of IRCT20141209020258N153.
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.
文摘Acute traumatic spinal cord injury is often a lifechanging and devastating event with considerable mortality and morbidity.Over half a million people suffer from traumatic spinal cord injury annually with the majority resulting from road traffic accidents or falls.The Individual,societal and economic costs are enormous.Initial recognition and treatment of acute traumatic spinal cord injury are crucial to limit secondary injury to the spinal cord and to provide patients with the best chance of some functional recovery.This article is an overview of the management of the acute traumatic spinal cord injury patient presenting to the emergency department.We review the initial assessment,criteria for imaging and clearing the spine,and evaluate the literature to determine the optimum timing of surgery and the role of non-surgical treatment in patients presenting with acute spinal cord injury.

文摘Osteoporotic vertebral compression fracture(OVCF)has become a major public health issue that becomes more pressing with increasing global aging.Percutaneous kyphoplasty(PKP)is an effective treatment for OVCF.Robot-assisted PKP has been utilized in recent years to improve accuracy and reduce complications.However,the effectiveness of robot-assisted PKP in the treatment of multi-segmental OVCF has yet to be proved.This study was designed to compare the efficacy of robot-assisted and conventional fluoroscopy-assisted multi-segmental PKP.A total of 30 cases with multi-segmental OVCF between April 2019 and April 2021 were included in this study.Fifteen cases were assigned to the robot-assisted PKP group(robot group)and 15 cases to the conventional fluoroscopy-assisted PKP group(conventional fluoroscopy group).The number of fluoroscopic exposures,fluoroscopic dose,operation time,cement leakage rate,visual analog scale(VAS)score,vertebral kyphosis angle(VKA),and height of fractured vertebral body(HFV)were compared between the 2 groups.The number of fluoroscopic exposures,fluoroscopic doses,and cement leakage rates in the robot group were lower than in the conventional fluoroscopy group(P<0.05)while the operative time in the robot group was longer than in the conventional fluoroscopy group(P<0.05).VAS score and VKA were decreased and HFV was increased after surgery in both groups(P<0.05).Therefore,robot-assisted PKP for the treatment of multi-segmental OVCF can reduce the number of fluoroscopic exposures,fluoroscopic doses,and cement leakage compared to conventional treatment.As such,robot-assisted PKP has good application prospects and is potentially more effective in the treatment of multi-segmental OVCF.

文摘Thoracolumbar fractures are usually treated by open posterior pedicle screw fixation.However,this procedure involves massive paraspinal muscle stripping,inflicting surgical trauma,and prolonged X-ray exposure.In this study,we observed 127 patients with single-segment injury thoracolumbar fractures.Thirty-six patients were treated by the modified Wiltse’s paraspinal approach with minimally invasive channel system,while 91 patients were treated via traditional posterior approach.Operation time,intraoperative blood loss,intraoperative fluoroscopy frequency,screw placement accuracy,visual analogue scale score,and Cobb’s angle of two groups were compared.The X-ray exposure times were notably reduced(4.2±1.6) in the new approach group(P<0.05).The pedicle screw placement accuracy and Cobb’s angle after surgery were similar in the two groups.We conclude that modified Wiltse’s paraspinal approach w ith spinal minimally invasive channel system surgery can significantly reduce the X-ray exposure times and is an alternative therapy for the thoracolumbar fracture.
文摘To evaluate the results of operative treatment of spinal fracture dislocation without neurologic deficits. Methods.Eighteen patients with spinal fracture dislocation were neurologically intact at the time of injury, and all were treated operatively. The fracture sites were:8 cases in cervical spine, 3 cases in thoracic spine, and 7 cases in lumbar spine. Eight patients with cervical injuries had variant degrees of forward slide and kyphotic deformity. Of the 10 thoracic and lumbar fractures, one had lateral dislocation, 4 cases with kyphotic deformities, 5 cases with spinal canal compromise averaged 50% (ranging from 40% to 70%). Results.The average period of follow up was 4.4 years with a range of 11 months to 13 years. All the patients returned to full time work. No patient developed neurologic deterioration. Kyphotic deformity was corrected in the 4 cases, and no progressive kyphosis was noted. There was no operation related complication. The averaged post operative hospitalization time was 13 days. Conclusions. Despite the rare incidence of spinal fracture dislocation without neurologic deficits, we suggested that kind of fracture be considered unstable fracture because of its potential risk of delayed neurologic deterioration and kyphotic deformity, and be treated operatively to restore the sagittal alignment and the stability of the spine.

文摘Purpose:To identify risk factors for developing pressure ulcers(PUs)in the acute care period of traumatic spinal fracture patients with or without spinal cord injuries(SCIs).Methods:Data were collected prospectively in participating the National Spinal column/Cord Injury Registry of Iran(NSCIR-IR)from individuals with traumatic spinal fractures with or without SCIs,in-clusive of the hospital stay from admission to discharge.Trained nursing staff examined the patients for the presence of PUs every 8 h during their hospital stay.The presence and grade of PUs were assessed according to the European Pressure Ulcer Advisory Panel classification.In addition to PU,following data were also extracted from the NSCIR-IR datasets during the period of 2015-2021:age,sex,Glasgow coma scale score at admission,having SCIs,marital status,surgery for a spinal fracture,American Spinal Injury Association impairment scale(AIS),urinary incontinence,level of education,admitted center,length of stay in the intensive care unit(ICU),hypertension,respiratory diseases,consumption of ciga-rettes,diabetes mellitus and length of stay in the hospital.Logistic regression models were used to es-timate the unadjusted and adjusted odds ratio(OR)with 95%confidence intervals(CI).Results:Altogether 2785 participants with traumatic spinal fractures were included.Among them,87(3.1%)developed PU during their hospital stay and 392(14.1%)had SCIs.In the SCI population,63(16.1%)developed PU during hospital stay.Univariate logistic regression for the whole sample showed that marital status,having SCIs,urinary incontinence,level of education,treating center,number of days in the ICU,age,and Glasgow coma scale score were significant predictors for PUs.However,further analysis by multiple logistic regression only revealed the significant risk factors to be the treating center,marital status,having SCIs,and the number of days in the ICU.For the subgroup of individuals with SCIs,marital status,AIS,urinary incontinence,level of education,the treating center,the number of days in the ICU and the number of days in the hospital were significant predictors for PUs by univariate analysis.After adjustment in the multivariate model,the treating center,marital status(singles vs.marrieds,OR=3.06,95%CI:1.55-6.03,p=0.001),and number of days in the ICU(OR=1.06,95%Cl:1.04-1.09,p<0.001)maintained significance.Conclusions:These data confirm that individuals with traumatic spinal fractures and SCIs,especially single young patients who suffer from urinary incontinence,grades A-D by AIS,prolonged ICU stay,and more extended hospitalization are at increased risk for PUs;as a result strategies to minimize PU development need further refinement.

文摘With the development of the rail transit industry,more attention has been paid to the passive safety of rail vehicles.Structural damage is one of the main failure behaviors in a rail vehicle collision,but it has been paid little attention to in past research.In this paper,the quasi-static fracture experiments of SUS301L-MT under different stress states were carried out.The mechanical fracture properties of this material were studied,and the corresponding finite element simulation accuracy was improved to guide the design of vehicle crashworthiness.Through the tests,the fracture behavior of materials with wide stress triaxiality was obtained,and each specimen’s fracture locations and fracture strains were determined.Parameters of a generalized incremental stress state dependent damage model(GISSMO)of the material were calibrated,and the model’s accuracy was verified with test results from a 45°shear specimen.The GISSMO failure model accurately reflected the fracture characteristics of the material.The mesh dependency of this model was modified and discussed.The results show that the simulation agrees well with experimental data for the force-displacement curve after correction,but the strain distribution needs to be further studied and improved.
文摘Objective. To investigate the unique characteristics and treatment of thoracic spine fractures. Methods. Seventy seven patients with thoracic spine fractures were retrospectively reviewed. Of these, there were 37 compression fractures, 34 fracture dislocations, 3 burst fractures and 3 burst dislocations. Twenty six patients had a complete lesion of the spinal cord, 14 sustained a neurologically incomplete injury, and 37 were neurologically intact. Fifty three patients were treated nonoperatively and 24 treated operatively. Results. All patients were followed up for 2~15 years. None of the 26 patients with a complete lesion recovered any significant function. Of 37 neurologically intact patients, 13 had local pain although all of them remained normal function. Two of 14 patients with incomplete paraplegia returned to normal, 7 recovered some function and 5 did not recovered. Conclusions. Because of the unique anatomy and biomechanics of the thoracic spine, the classification commonly applied to thoracolumbar fractures is not suitable for thoracic fractures. Fusion and instrumentation are indicated when the fractures are unstable, while patients with incomplete lesion of the spinal cord may be the candidates for supplemented decompression.
文摘Objective:To analyze the effect of protection motivation theory on the quality of life of patients with spinal fracture.Methods:From August 2019 to September 2020,72 patients with spinal fracture were selected and randomly divided into two groups.The routine nursing group was the routine nursing group,and the combined nursing with the theory of protective motivation was the dynamic nursing group.Results:The hospitalization time,detumescence time,healing time and muscle strength recovery time of group A were shorter than those of group B(P<0.05).The VAS score and Barthel index score of the dynamic group were better than those of the conventional group(P<0.05);The score of SF-36 in the group A was higher than that in the group B(P<0.05).Conclusions:The application of protection motivation theory in the nursing of patients with spinal fracture can shorten the healing time of fracture,promote the recovery of muscle strength,relieve the pain of fracture,and then improve the ability of daily life and quality of life of patients.
