The main objective of this study was to research risk factors for bleeding and transfusion in patients undergoing hip hemiarthroplasty in Gabon. Method: It was a retrospective, monocentric, descriptive and analytical study carried out from June 2011 to June 2021 at the Omar Bongo Ondimba army training hospital. The variables studied were demographic characteristics, biological variables, transfusion and intraoperative data. The primary outcome was intraoperative transfusion. A univariate and multivariate analysis was conducted to identify the factors associated with the occurrence of a transfusion. Results: Of the 97 patients included, the average age was 74.2 years ± 10, male predominance was 73.2%, the average ASA score was 1.9 ± 0.5, and transfusion incidence was 38.1%. The average number of RBCs transfused was 1.2 ± 0.6. Tranexamic acid was used in 11.3% of patients. The average bleeding was 450 ± 453 ml. Preoperative anemia was predictor of transfusion to be significant. Conclusion: The incidence of transfusion is law compared to total hip arthroplasty. The implementation of a patient blood management protocol is difficult given the urgency of bone repair. However, a better use of tranexamic acid could reduce this transfusion incidence.展开更多

We investigated UI symptoms before and after THA at our facility and considered the factors that influence UI. Patients and Method: The subjects were 113 female patients who underwent primary THA in our facility. An anterior lateral approach was used in all cases. Using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), we conducted an investigation into the presence of UI before and 2 weeks after THA. An improvement in UI was defined as a decrease of 1 point or more, a worsening is defined as an increase of 1 point or more. Results: The responses from the 113 subjects were analyzed. Of the 113 patients, prior to THA, UI was prevalent among 59 patients and was absent among 54 patients. In the group where UI was prevalent, it improved after THA in 50 patients (85%), remained unchanged in 5 (8%) and worsened in 4 (7%). In the group where UI was absent, 49 patients (91%) remained unchanged and UI appeared in 5 (9%). Compared with the non-prevalence group (62 patients), the prevalence group (50 patients) had a noticeable improvement rate of internal rotation of the surgical hip side (P Conclusion: UI greatly reduces the quality of life (QOL). In this study, there is a possibility that THA improves UI.展开更多

The main objective of this study was to research risk factors for bleeding and transfusion in patients undergoing hip arthroplasty in order to guide a blood-saving program. Method: Retrospective, monocentric, descriptive and analytical study carried out from June 2011 to June 2021 at the Omar Bongo Ondimba army training hospital. The variables studied were demographic characteristics, biological variables, transfusion data, anesthetic and intraoperative data. The primary outcome was intraoperative or postoperative transfusion. A univariate and multivariate analysis was conducted to identify the factors associated with the occurrence of a transfusion. Results: Of the 276 patients included, 179 benefited from Total Hip Prosthesis (THP) and 97 from Intermediate Hip Prosthesis (IHP). Spinal anesthesia was performed in 67.4% of patients. The ASA 2 score predominated (65.9%). The transfusion incidence was 56.9% (157/276). Tranexamic acid was used in 16.3% (45/276) of patients. The average bleeding was 528 ± 405 ml. Preoperative anemia (OR = 0.78, 95% CI [0.66 - 0.91]) and total hip prosthesis (OR = 2.02 95% CI [1.11 - 3.67]) were predictors of bleeding and transfusion to be significant. The average serum hemoglobin predictive of a transfusion was 11.6 ± 1.8. ASA score and operative time were not found as risk factors for bleeding and transfusion. Conclusion: The incidence of transfusion is high. Preoperative anemia remains a major but modifiable risk factor unlike the choice of implant. The implementation of a patient blood management protocol could reduce this transfusion incidence.展开更多

The interest of this study results from the need to adapt our practices to the socio-economic status of our patients. The aim of this study was to describe the epidemiological profile of patients, the indications and results of hip arthroplasties performed in our hospital. Methodology: A descriptive monocentric study was conducted from January 2010 to December 2019 at Treichville University Teaching Hospital. All patients, who underwent total hip arthroplasty or hemiarthroplasty with intermediate or cervico-cephalic prosthesis, were included in the study. Epidemiological, clinical, therapeutic and follow-up data were analysed. Results: We collected 95 patients with 97 hips operated. The mean age was 67 years. 56% of patients were male. Arthroplasty was performed after femoral neck fractures in 78% of cases, followed by osteonecrosis of the femoral head (15%). The left side was affected in 51% of cases. The Moore’s posterior approach was used in 79% of cases, followed by the Hardinge’s lateral approach (21%). Hemiarthroplasties were implanted in 78% of patients. We observed 4 dislocations and 3 post-operative infections at 48 months of follow-up. The mean Harris score was 75.2. Conclusion: Arthroplasty has improved the function of our patients. Most of young males undergo the arthroplasty. Intermediate prostheses are commonly used implants.展开更多

The research adopted a prospective method, assessing epidemiological, clinical, radiological, and therapeutic aspects, utilizing the Postel Merle d’Aubigné scoring system for functional assessment. Results demonstrated that total joint replacement surgery, predominantly following traffic accidents, significantly improved mobility and reduced limb length disparity, with most patients achieving independent walking post-operation. The study concludes that early diagnosis and total hip arthroplasty are critical for optimal outcomes.展开更多

文摘BACKGROUND Total hip arthroplasty is as an effective intervention to relieve pain and improve hip function.Approaches of the hip have been exhaustively explored about pros and cons.The efficacy and the complications of hip approaches remains inconclusive.This study conducted an umbrella review to systematically appraise previous meta-analysis(MAs)including conventional posterior approach(PA),and minimally invasive surgeries as the lateral approach(LA),direct anterior approach(DAA),2-incisions method,mini-lateral approach and the newest technique direct superior approach(DSA)or supercapsular percutaneouslyassisted total hip(SuperPath).AIM To compare the efficacy and complications of hip approaches that have been published in all MAs and randomized controlled trials(RCTs).METHODS MAs were identified from MEDLINE and Scopus from inception until 2023.RCTs were then updated from the latest MA to September 2023.This study included studies which compared hip approaches and reported at least one outcome such as Harris Hip Score(HHS),dislocation,intra-operative fracture,wound compliData were independently selected,extracted and assessed by two reviewers.Network MA and cluster rank and surface under the cumulative ranking curve(SUCRA)were estimated for treatment efficacy and safety.RESULTS Finally,twenty-eight MAs(40 RCTs),and 13 RCTs were retrieved.In total 47 RCTs were included for reanalysis.The results of corrected covered area showed high degree(13.80%).Among 47 RCTs,most of the studies were low risk of bias in part of random process and outcome reporting,while other domains were medium to high risk of bias.DAA significantly provided higher HHS at three months than PA[pooled unstandardized mean difference(USMD):3.49,95%confidence interval(CI):0.98,6.00 with SUCRA:85.9],followed by DSA/SuperPath(USMD:1.57,95%CI:-1.55,4.69 with SUCRA:57.6).All approaches had indifferent dislocation and intraoperative fracture rates.SUCRA comparing early functional outcome and composite complications(dislocation,intra-operative fracture,wound complication,and nerve injury)found DAA was the best approach followed by DSA/SuperPath.CONCLUSION DSA/SuperPath had better earlier functional outcome than PA,but still could not overcome the result of DAA.This technique might be the other preferred option with acceptable complications.
文摘BACKGROUND Prophylactic antibiotics have significantly led to a reduction in the risk of postoperative surgical site infections(SSI)in orthopaedic surgery.The aim of using antibiotics for this purpose is to achieve serum and tissue drug levels that exceed,for the duration of the operation,the minimum inhibitory concentration of the likely organisms that are encountered.Prophylactic antibiotics reduce the rate of SSIs in lower limb arthroplasty from between 4%and 8%to between 1%and 3%.Controversy,however,still surrounds the optimal frequency and dosing of antibiotic administration.AIM To evaluate the impact of introduction of a weight-adjusted antibiotic prophylaxis regime,combined with a reduction in the duration of administration of post-operative antibiotics on SSI incidence during the 2 years following primary elective total hip and knee arthroplasty METHODS Following ethical approval,patients undergoing primary total hip arthroplasty(THA)/total knee arthroplasty(TKA)with the old regime(OR)of a preoperative dose[cefazolin 2 g intravenously(IV)],and two subsequent doses(2 h and 8 h),were compared to those after a change to a new regime(NR)of a weight-adjusted preoperative dose(cefazolin 2 g IV for patients<120 kg;cefazolin 3g IV for patients>120 kg)and a post-operative dose at 2 h.The primary outcome in both groups was SSI rates during the 2 years post-operatively.RESULTS A total of n=1273 operations(THA n=534,TKA n=739)were performed in n=1264 patients.There was no statistically significant difference in the rate of deep(OR 0.74%(5/675)vs NR 0.50%(3/598);fishers exact test P=0.72),nor superficial SSIs(OR 2.07%(14/675)vs NR 1.50%(9/598);chi-squared test P=0.44)at 2 years postoperatively.With propensity score weighting and an interrupted time series analysis,there was also no difference in SSI rates between both groups[RR 0.88(95%CI 0.61 to 1.30)P=0.46].CONCLUSION A weight-adjusted regime,with a reduction in number of post-operative doses had no adverse impact on SSI incidence in this population.
文摘BACKGROUND Total hip arthroplasty(THA)is a common procedure for end stage osteoarthritis.The learning curve for THA is complex and challenging.One of the most difficult skills to master is acetabular reaming.We wish to identify if experience in arthroplasty leads to preservation of more bone stock.AIM To investigate if increasing surgeon experience will predict an ever decreasing acetabular cup size.METHODS A retrospective case series of four attending orthopaedic surgeons was completed.All uncemented elective total hip arthroplasties since appointment were selected for inclusion.The size of acetabular cup used was noted and logistic regression was used to identify if a trend to smaller cups existed.RESULTS A total of 1614 subjects were included with a mean age of 64 years.Overall cups were on average 0.18mm smaller per year(95%confidence interval-0.25 to-0.11,P<0.001).Individual surgeon trends showed cup sizes to decrease 0.27 mm/year for surgeon A,0.02 mm/year for surgeon B,0.15 mm/year for surgeon C and 0.29 mm/year for surgeon D.Three of the four surgeons had a more pronounced trend to smaller cups for male subjects than their female counterparts.CONCLUSION We found increasing surgeon experience to be associated with an ever-decreasing acetabular cup size.Smaller acetabular cup size may act as a surrogate marker of surgical proficiency by virtue of decreased acetabular reaming.
文摘In this editorial I comment on the article by Ahmed et al published in a recent issue of the World J Orthop 2023;14:784-790.It is well known that patients who have undergone a liver transplant(LT)may need to have a total hip arthroplasty(THA)or total knee arthroplasty(TKA)implanted.Ahmed et al stated that the mortality rate in these patients was similar to the one of the general population.However,there are three articles previously published that found higher mortality in LT patients who experienced THA/TKA than in the general population(individuals without LT).Therefore,in this Editorial I would like to point out that there is controversy in the literature regarding whether LT patients undergoing THA/TKA have higher mortality than the general population.Therefore,future research should attempt to resolve this controversy.
文摘BACKGROUND Acetabular component positioning in total hip arthroplasty(THA)is of key importance to ensure satisfactory post-operative outcomes and to minimize the risk of complications.The majority of acetabular components are aligned freehand,without the use of navigation methods.Patient specific instruments(PSI)and three-dimensional(3D)printing of THA placement guides are increasingly used in primary THA to ensure optimal positioning.AIM To summarize the literature on 3D printing in THA and how they improve acetabular component alignment.METHODS PubMed was used to identify and access scientific studies reporting on different 3D printing methods used in THA.Eight studies with 236 hips in 228 patients were included.The studies could be divided into two main categories;3D printed models and 3D printed guides.RESULTS 3D printing in THA helped improve preoperative cup size planning and post-operative Harris hip scores between intervention and control groups(P=0.019,P=0.009).Otherwise,outcome measures were heterogeneous and thus difficult to compare.The overarching consensus between the studies is that the use of 3D guidance tools can assist in improving THA cup positioning and reduce the need for revision THA and the associated costs.CONCLUSION The implementation of 3D printing and PSI for primary THA can significantly improve the positioning accuracy of the acetabular cup component and reduce the number of complications caused by malpositioning.
文摘BACKGROUND Hip fractures account for 23.8%of all fractures in patients over the age of 75 years.More than half of these patients are older than 80 years.Bipolar hemiarthroplasty(BHA)was established as an effective management option for these patients.Various approaches can be used for the BHA procedure.However,there is a high risk of postoperative dislocation.The conjoined tendon-preserving posterior(CPP)lateral approach was introduced to reduce postoperative dislocation rates.AIM To evaluate the effectiveness and safety of the CPP lateral approach for BHA in elderly patients.METHODS We retrospectively analyzed medical data from 80 patients with displaced femoral neck fractures who underwent BHA.The patients were followed up for at least 1 year.Among the 80 patients,57(71.3%)were female.The time to operation averaged 2.3 d(range:1-5 d).The mean age was 80.5 years(range:67-90 years),and the mean body mass index was 24.9 kg/m^(2)(range:17-36 kg/m^(2)).According to the Garden classification,42.5%of patients were typeⅢand 57.5%of patients were typeⅣ.Uncemented bipolar hip prostheses were used for all patients.Torn conjoined tendons,dislocations,and adverse complications during and after surgery were recorded.RESULTS The mean postoperative follow-up time was 15.3 months(range:12-18 months).The average surgery time was 52 min(range:40-70 min)with an average blood loss of 120 mL(range:80-320 mL).The transfusion rate was 10%(8 of 80 patients).The gemellus inferior was torn in 4 patients(5%),while it was difficult to identify in 2 patients(2.5%)during surgery.The posterior capsule was punctured by the fractured femoral neck in 3 patients,but the conjoined tendon and the piriformis tendon remained intact.No patients had stem varus greater than 3 degrees or femoral fracture.There were no patients with stem subsidence more than 5 mm at the last follow-up.No postoperative dislocations were observed throughout the follow-up period.No significance was found between preoperative and postoperative mean Health Service System scores(87.30±2.98 vs 86.10±6.10,t=1.89,P=0.063).CONCLUSION The CPP lateral approach can effectively reduce the incidence of postoperative dislocation without increasing perioperative complications.For surgeons familiar with the posterior lateral approach,there is no need for additional surgical instruments,and it does not increase surgical difficulty.
文摘BACKGROUND With the continuous growth of the modern elderly population,the risk of fracture increases.Hip fracture is a common type of fracture in older people.Total hip arthroplasty(THA)has significant advantages in relieving chronic pain and promoting the recovery of hip joint function.AIM To investigate the effect of ulinastatin combined with dexmedetomidine(Dex)on the incidences of postoperative cognitive dysfunction(POCD)and emergence agitation in elderly patients who underwent THA.METHODS A total of 397 patients who underwent THA from February 2019 to August 2022.We conducted a three-year retrospective cohort study in Shaanxi Provincial People’s Hospital.Comprehensive demographic data were obtained from the electronic medical record system.We collected preoperative,intraoperative,and postoperative data.One hundred twenty-nine patients who were administered Dex during the operation were included in the Dex group.One hundred fifty patients who were intravenously injected with ulinastatin 15 min before anesthesia induction were included in the ulinastatin group.One hundred eighteen patients who were administered ulinastatin combined with Dex during the operation were included in the Dex+ulinastatin group.The patients’perioperative conditions,hemodynamic indexes,postoperative Mini-Mental State Examination(MMSE)scores,Ramsay score,incidence of POCD,and serum inflammatory cytokines were evaluated.RESULTS There was a significant difference in the 24 h visual analogue scale score among the three groups,and the score in the Dex+ulinastatin group was the lowest(P<0.05).Compared with the Dex and ulinastatin group,the MMSE scores of the Dex+ulinastatin group were significantly increased at 1 and 7 d after the operation(all P<0.05).Compared with those in the Dex and ulinastatin groups,incidence of POCD,levels of serum inflammatory cytokines in the Dex+ulinastatin group were significantly decreased at 1 and 7 d after the operation(all P<0.05).The observer’s assessment of the alertness/sedation score and Ramsay score of the Dex+ulinastatin group were significantly different from those of the Dex and ulinastatin groups on the first day after the operation(all P<0.05).CONCLUSION Ulinastatin combined with Dex can prevent the occurrence of POCD and emergence agitation in elderly patients undergoing THA.
文摘Background: Hip arthroplasty is a surgery with a high risk of bleeding. The main objective of this study was to research risk factors for bleeding and transfusion in patients undergoing hip hemiarthroplasty in Gabon. Method: It was a retrospective, monocentric, descriptive and analytical study carried out from June 2011 to June 2021 at the Omar Bongo Ondimba army training hospital. The variables studied were demographic characteristics, biological variables, transfusion and intraoperative data. The primary outcome was intraoperative transfusion. A univariate and multivariate analysis was conducted to identify the factors associated with the occurrence of a transfusion. Results: Of the 97 patients included, the average age was 74.2 years ± 10, male predominance was 73.2%, the average ASA score was 1.9 ± 0.5, and transfusion incidence was 38.1%. The average number of RBCs transfused was 1.2 ± 0.6. Tranexamic acid was used in 11.3% of patients. The average bleeding was 450 ± 453 ml. Preoperative anemia was predictor of transfusion to be significant. Conclusion: The incidence of transfusion is law compared to total hip arthroplasty. The implementation of a patient blood management protocol is difficult given the urgency of bone repair. However, a better use of tranexamic acid could reduce this transfusion incidence.
文摘BACKGROUND Selecting the optimal size of components is crucial when performing a primary total hip arthroplasty.Implanting the accurate size of the acetabular component can occasionally be exacting,chiefly for surgeons with little experience,whilst the complications of imprecise acetabular sizing or over-reaming can be potentially devastating.AIM To assist clinicians intraoperatively with a simple and repeatable tip in elucidating the ambivalence when determining the proper acetabular component size is not straightforwardly achieved,specifically when surgeons are inexperienced or preoperative templating is unavailable.METHODS This method was employed in 263 operations in our department from June 2021 to December 2022.All operations were performed by the same team of joint reconstruction surgeons,employing a typical posterior hip approach technique.The types of acetabular shells implanted were:The Dynasty®acetabular cup system(MicroPort Orthopedics,Shanghai,China)and the R3®acetabular system(Smith&Nephew,Watford,United Kingdom),which both feature cementless press-fit design.RESULTS The mean value of all cases was calculated and collated with each other.We distinguished as oversized an implanted acetabular shell when its size was>2 mm larger than the size of the acetabular size indicator reamer(ASIR)or when the implanted shell was larger than 4 mm compared to the preoperative planned cup.The median size of the implanted acetabular shell was 52(48–54)mm,while the median size of the preoperatively planned cup was 50(48–56)mm,and the median size of the ASIR was 52(50–54)mm.The correlation coefficient between ASIR size and implanted acetabular component size exhibited a high positive correlation with r=0.719(P<0.001).Contrariwise,intraoperative ASIR measurements precisely predicted the implanted cups’size or differed by only one size(2 mm)in 245 cases.CONCLUSION In our study,we demonstrated that the size of the first acetabular reamer not entering freely in the acetabular rim corroborates the final acetabular component size to implant.This was also corresponding in the majority of the cases with conventional preoperative templating.It can be featured as a valid tool for avoiding the potentially pernicious complications of acetabular cup over-reaming and over-sizing in primary total hip arthroplasty.It is a simple and reproducible technical note useful for confirming the predicted acetabular cup size preoperatively;thus,its application could be considered routinely,even in cases where preoperative templating is unavailable.

文摘BACKGROUND Osteonecrosis of the femoral head(ONFH)is a prevalent orthopedic issue,leading to the collapse and fragmentation of the femoral head in its advanced stages,which can severely impair patients'quality of life.Total hip arthroplasty(THA)is a clinical intervention frequently used to alleviate ONFH symptoms and reinstate hip functionality.The conventional surgical technique is invasive and comes with an extended recuperation period,posing significant challenges for patients.With the progression of medical technology,the use of the mini-incision technique in minimally invasive THA(MITHA)has become more prevalent.However,comparative studies examining the effectiveness of these two surgical procedures in treating ONFH remain scarce.Furthermore,understanding patients'psychological well-being is crucial given its profound influence on postoperative recuperation.AIM To evaluate the impact of mini-incision MITHA on ONFH treatment and to identify the risk factors associated with postoperative anxiety and depression.METHODS A retrospective study was conducted on 125 patients treated for ONFH at Xi’an Hong Hui Hospital between February 2020 and January 2022,with the term"consecutive"indicating that these patients were treated in an unbroken sequence without any selection.Among these,60 patients(control group)underwent traditional THA,while 65 patients(observation group)were treated with miniincision MITHA.Variations in the visual analog scale(VAS)score and the Harris hip score were monitored.Additionally,shifts in pre-and posttreatment Hamilton anxiety(HAMA)and Hamilton depression(HAMD)scale scores were recorded.Patients with both postoperative HAMA and HAMD scores of≥8 were identified as those experiencing negative emotions.Logistic regression was utilized to analyze the determinants influencing these negative emotional outcomes.Comparative analyses of surgical and postoperative metrics between the two groups were also conducted.RESULTS Posttreatment results indicated a significantly higher VAS score in the control group than in the observation group,while the Harris score was considerably lower(P<0.0001).The observation group benefited from a notably shorter operation duration,reduced blood loss,diminished incision size,and a decreased postoperative drainage time(P<0.0001),accompanied by a reduced hospital stay and lower treatment costs(P<0.0001).The control group had elevated posttreatment HAMA and HAMD scores in comparison to the observation group(P<0.0001).Multivariate logistic regression revealed that being female[odds ratio(OR):4.394,95%CI:1.689-11.433,P=0.002],having a higher postoperative VAS score(OR:5.533,95%CI:2.210-13.848,P<0.0001),and having higher treatment costs(OR:7.306,95%CI:2.801-19.057,P<0.0001)were significant independent determinants influencing postoperative mood disturbances.CONCLUSION Compared to conventional THA,mini-incision MITHA offers advantages such as reduced operation time,minimal bleeding,and a shorter incision in ONFH patients.Moreover,factors such as sex,postoperative pain(reflected in the VAS score),and treatment costs significantly impact postoperative anxiety and depression.
文摘Introduction: In my daily practice as a hip surgeon, I have observed some circumstances where urinary incontinence (UI) improves after total hip arthroplasty (THA). We investigated UI symptoms before and after THA at our facility and considered the factors that influence UI. Patients and Method: The subjects were 113 female patients who underwent primary THA in our facility. An anterior lateral approach was used in all cases. Using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), we conducted an investigation into the presence of UI before and 2 weeks after THA. An improvement in UI was defined as a decrease of 1 point or more, a worsening is defined as an increase of 1 point or more. Results: The responses from the 113 subjects were analyzed. Of the 113 patients, prior to THA, UI was prevalent among 59 patients and was absent among 54 patients. In the group where UI was prevalent, it improved after THA in 50 patients (85%), remained unchanged in 5 (8%) and worsened in 4 (7%). In the group where UI was absent, 49 patients (91%) remained unchanged and UI appeared in 5 (9%). Compared with the non-prevalence group (62 patients), the prevalence group (50 patients) had a noticeable improvement rate of internal rotation of the surgical hip side (P Conclusion: UI greatly reduces the quality of life (QOL). In this study, there is a possibility that THA improves UI.
文摘Hip replacement(HA)is mainly indicated for the elderly,who generally suffer from various underlying diseases such as hypertension.This article provides a review of the key points of perioperative nursing care for patients with hyper-tension undergoing HA.It analyzes the key points of care during the periop-erative period(preoperative,intraoperative,and postoperative)and proposes directions for the development of perioperative nursing care for HA.The pro-gnosis for patients can be improved through the modification of traditional medical approaches and the application of new technologies and concepts.
文摘BACKGROUND Presepsin is an emerging biomarker in the diagnosis of sepsis.In the field of orthopaedics,it could be useful in diagnosing and managing periprosthetic joint infections.AIM To define the normal postoperative presepsin plasmatic curve,in patients undergoing primary cementless total hip arthroplasty(THA).METHODS Patients undergoing primary cementless THA at our Institute were recruited.Inclusion criteria were:Primary osteoarthritis of the hip;urinary catheter time of permanence<24 h;peripheral venous cannulation time of permanence<24 h;no postoperative homologous blood transfusion administration and hospital stay≤8 d.Exclusion criteria were:The presence of other articular prosthetic replacement or bone fixation devices;chronic inflammatory diseases;chronic kidney diseases;history of recurrent infections or malignant neoplasms;previous surgery in the preceding 12 mo;diabetes mellitus;immunosuppressive drug or corticosteroid assumption.All the patients received the same antibiotic prophylaxis.All the THA were performed by the same surgical and anaesthesia team;total operative time was defined as the time taken from skin incision to completion of skin closure.At enrollment,anthropometric data,smocking status,osteoarthritis stage according to Kellgren and Lawrence,Harris Hip Score,drugs assumption and comorbidities were recorded.All the patients underwent serial blood tests,including complete blood count,presepsin(PS)and C-reactive protein 24 h before arthroplasty and at 24,48,72 and 96 h postoperatively and at 3,6 and 12-mo follow-up.RESULTS A total of 96 patients(51 female;45 male;mean age=65.74±5.58)were recruited.The mean PS values were:137.54 pg/mL at baseline,192.08 pg/mL at 24 h post-op;254.85 pg/mL at 48 h post-op;259 pg/mL at 72 h post-op;248.6 pg/mL at 96-h post-op;140.52 pg/mL at 3-mo follow-up;135.55 pg/mL at 6-mo follow-up and 130.11 pg/mL at 12-mo follow-up.In two patients(2.08%)a soft-tissue infection was observed;in these patients,higher levels(>350 pg/mL)were recorded at 3-mo follow-up.CONCLUSION The dosage of plasmatic PS concentration is highly recommended in patients undergoing THA before surgery to exclude the presence of an unknown infection.The PS plasmatic concentration should be also assessed at 72 h postoperatively,evaluate the maximum postoperative PS value,and at 96 h post-operatively when a decrease of presepsin should be found.The lack of a presepsin decrease at 96 h post-operatively could be a predictive factor of infection.
文摘BACKGROUND Proximal femur fractures,including both intracapsular(femoral neck fractures)and extracapsular fractures(intertrochanteric femoral fractures,IFFs),affect around 1.5 million people per year worldwide.Mechanical failures of intertrochanteric nailing in IFFs could be managed with revision total hip arthroplasty(THA).AIM To describe the surgical complexity and the procedure-related complication rates in patients with trochanteric nailing failure and treated with THA.METHODS Patients referred to our level I trauma center between April 2012 and July 2018 with failed cephalomedullary nailing following trochanteric fractures were retrospectively recruited.All patients underwent a salvage surgical procedure,i.e.,cephalomedullary nail removal and conversion to THA.The same surgical and anesthesiology team performed the surgical procedures under spinal anesthesia.All patients underwent clinical and radiographic follow-ups for at least 24 mo.Complications and re-operations were recorded.RESULTS Seventy-four patients met the inclusion criteria(male:29;female:45;mean age:73.8-years-old;range:65-89)and were included in the current study.The average operative time was 117 min(76-192 min).The average blood loss was 585 mL(430-1720 mL).Among the 74 patients,43(58.1%)required transfusion of three or more blood units.Two patients died within the 4th d after surgery because of pulmonary embolism,and 1 patient died 9 mo after surgery due to ischemic myocardial infarction.The complication rate in the 71 patients who completed the minimum 24-mo follow-up was 22.5%.In 3 cases out of 71(4.2%)periprosthetic acetabular fracture was observed during the followup.One of these periacetabular fractures occurred intraoperatively.An intraoperative periprosthetic femur fracture was observed in 5 patients out of 71(7.0%).Four of these patients needed a re-operation to fix the fracture with plates and cerclages;in one of these patients,femoral stem revision was also necessary.In 4 patients out of 71(5.6%),an early THA dislocation was observed,whereas in 1 case(1.4%)a late THA dislocation was observed.Three patients out of 71(4.2%)developed a periprosthetic joint infection during the study follow-up.CONCLUSION The present study demonstrated that salvage options for IFF fixation failure are complex procedures with a relevant intraoperative and postoperative complication rate.
文摘Background: Hip arthroplasty is a surgery with a high risk of bleeding. The main objective of this study was to research risk factors for bleeding and transfusion in patients undergoing hip arthroplasty in order to guide a blood-saving program. Method: Retrospective, monocentric, descriptive and analytical study carried out from June 2011 to June 2021 at the Omar Bongo Ondimba army training hospital. The variables studied were demographic characteristics, biological variables, transfusion data, anesthetic and intraoperative data. The primary outcome was intraoperative or postoperative transfusion. A univariate and multivariate analysis was conducted to identify the factors associated with the occurrence of a transfusion. Results: Of the 276 patients included, 179 benefited from Total Hip Prosthesis (THP) and 97 from Intermediate Hip Prosthesis (IHP). Spinal anesthesia was performed in 67.4% of patients. The ASA 2 score predominated (65.9%). The transfusion incidence was 56.9% (157/276). Tranexamic acid was used in 16.3% (45/276) of patients. The average bleeding was 528 ± 405 ml. Preoperative anemia (OR = 0.78, 95% CI [0.66 - 0.91]) and total hip prosthesis (OR = 2.02 95% CI [1.11 - 3.67]) were predictors of bleeding and transfusion to be significant. The average serum hemoglobin predictive of a transfusion was 11.6 ± 1.8. ASA score and operative time were not found as risk factors for bleeding and transfusion. Conclusion: The incidence of transfusion is high. Preoperative anemia remains a major but modifiable risk factor unlike the choice of implant. The implementation of a patient blood management protocol could reduce this transfusion incidence.

文摘BACKGROUND Chronic obstructive pulmonary disease(COPD)is a common respiratory disorder that affects the elderly population and increases the risk of postoperative pulmonary complications(PPCs)after major surgeries.Sevoflurane is a volatile anesthetic that has been shown to have anti-inflammatory and antioxidant properties and attenuate lung injury in animal models.AIM To evaluate the protective effect of sevoflurane on the lung function of elderly COPD patients undergoing total hip arthroplasty(THA).METHODS In this randomized controlled trial,we randomly assigned 120 elderly patients with COPD,who were scheduled for THA,to receive either sevoflurane(sevoflurane group)or propofol(propofol group)as the maintenance anesthetic.The primary outcome was the incidence of PPCs within seven days after surgery.The secondary outcomes were changes in the lung function parameters,inflammatory markers,oxidative stress markers,and postoperative pain scores.RESULTS The results showed that the incidence of PPCs was significantly lower in the sevoflurane group than in the propofol group(10%vs 25%,P=0.02).Furthermore,the decline in the forced expiratory volume in 1 s,forced vital capacity,and peak expiratory flow was significantly lesser in the sevoflurane group than in the propofol group at 24 h and 48 h after surgery(P<0.05).The interleukin-6,tumor necrosis factor-alpha,malondialdehyde,and 8-hydroxy-2α-deoxyguanosine levels were significantly lower in the sevoflurane group than in the propofol group at 24 h after surgery(P<0.05).The sevoflurane group showed significantly lower postoperative pain scores than the propofol group at 6 h,12 h,and 24 h after surgery(P<0.05).CONCLUSION Sevoflurane protects the lung function of elderly COPD patients undergoing THA under general anesthesia by reducing the incidence of PPCs,attenuating inflammatory and oxidative stress responses,and alleviating postoperative pain.

文摘BACKGROUND Total hip arthroplasty(THA)is an effective treatment for advanced osteonecrosis of the femoral head,which can significantly relieve pain and improve patients'quality of life.Robotic-assisted THA enhances the accuracy and stability of THA surgery and achieves better clinical outcomes than manual THA.CASE SUMMARY We report the clinical outcomes of robotic-assisted THA and manual THA in the same patient with osteonecrosis of the femoral head.A 49-year-old male patient attended our hospital due to more than 3 years of pain in both hip joints.The left hip was treated with robotic-assisted THA.The patient underwent manual THA of the right hip 3 mo after robotic-assisted THA.We obtained postoperative radiograph parameters,Harris hip score and forgotten joint score of the patient 1 year after surgery.CONCLUSION Compared with manual THA,the patient’s left hip felt better 1 year after roboticassisted THA.Robotic-assisted THA resulted in a better Harris hip score and forgotten joint score than manual THA in the same patient with osteonecrosis of the femoral head.
文摘Objective: Hip arthroplasty has variable and codified indications. The interest of this study results from the need to adapt our practices to the socio-economic status of our patients. The aim of this study was to describe the epidemiological profile of patients, the indications and results of hip arthroplasties performed in our hospital. Methodology: A descriptive monocentric study was conducted from January 2010 to December 2019 at Treichville University Teaching Hospital. All patients, who underwent total hip arthroplasty or hemiarthroplasty with intermediate or cervico-cephalic prosthesis, were included in the study. Epidemiological, clinical, therapeutic and follow-up data were analysed. Results: We collected 95 patients with 97 hips operated. The mean age was 67 years. 56% of patients were male. Arthroplasty was performed after femoral neck fractures in 78% of cases, followed by osteonecrosis of the femoral head (15%). The left side was affected in 51% of cases. The Moore’s posterior approach was used in 79% of cases, followed by the Hardinge’s lateral approach (21%). Hemiarthroplasties were implanted in 78% of patients. We observed 4 dislocations and 3 post-operative infections at 48 months of follow-up. The mean Harris score was 75.2. Conclusion: Arthroplasty has improved the function of our patients. Most of young males undergo the arthroplasty. Intermediate prostheses are commonly used implants.
文摘This study examined neglected hip fracture-dislocations in developing countries, focusing on five cases in Dakar. The research adopted a prospective method, assessing epidemiological, clinical, radiological, and therapeutic aspects, utilizing the Postel Merle d’Aubigné scoring system for functional assessment. Results demonstrated that total joint replacement surgery, predominantly following traffic accidents, significantly improved mobility and reduced limb length disparity, with most patients achieving independent walking post-operation. The study concludes that early diagnosis and total hip arthroplasty are critical for optimal outcomes.
文摘Surgical site infections(SSI)following total joint arthroplasty pose a significant concern for both providers and patients across the globe.Currently,administration of antimicrobial antibiotic prophylaxis is used throughout the world to reduce the incidence of SSI.However,the correct dosage and frequency of administration remains debatable.In this editorial,we emphasized the determination of the effect of administration of weight-adjusted antimicrobial antibiotic prophylaxis regime on the incidence of SSI and postoperative dosage reduction compared to the conventionally used regime during total joint arthroplasty.The results demonstrated similar efficacy between both regimes with respect to the incidence of SSI.In addition,weight-adjustment led to reduced postoperative dosage and has the potential to reduce chances of achieving lower therapeutic concentration,drug resistance,drug toxicity,and costs.
