Due to their advanced age and the presence of some primary diseases, both anesthesia and surgery are increasingly difficult in elderly patients with a femoral neck fractures. In fact,general anesthesia can easily induce complications such as cognitive dysfunction,which is not conducive to postoperative recovery.AIM To analyze the efficacy of dexmedetomidine in inducing anesthesia for elderly patients undergoing hip replacement surgery.METHODS A total of 98 elderly patients undergoing hip replacement in our hospital from June 2020 to June 2021 were randomly divided into control group(49 cases) and observation group(49 cases). The control group was given general anesthesia, and the observation group was combined with dexmedetomidine for anesthesia on the basis of the control group. Both groups were observed until the patients were discharged. The vital signs, serum inflammatory factors and renal function indexes of the two groups were compared before, during and 6 h after operation.The postoperative recovery and adverse events of the two groups were statistically analyzed.RESULTS Compared with the mean arterial pressure of the two groups, the intraoperative and postoperative 6 h was higher than that before the operation, the intraoperative was lower than the postoperative 6 h(P < 0.05);the blood oxygen saturation of the two groups was higher than that before operation and 6 h after operation, and the observation group was higher than the control group 6 h after operation(P < 0.05). The heart rate of the two groups was lower during and 6 h after operation than that before operation, and higher at 6 h after operation than that during operation(P < 0.05).The levels of serum C-reactive protein, tumor necrosis factor-α, interleukin-1β and kidney injury molecule-1 in the two groups were higher during operation and 6 h after operation than those before operation(P < 0.05). The level of serum urea nitrogen in the two groups was higher than that before operation, and that in the observation group was lower than that in the control group(P < 0.05). During hospitalization, the first time of getting out of bed, recovery time of grade Ⅱ muscle strength, recovery time of grade Ⅲ muscle strength and hospitalization time in the observation group were shorter than those in the control group(P < 0.05).CONCLUSION Dexmedetomidine can effectively improve the vital signs of elderly patients undergoing hip replacement surgery, reduce the body’s inflammatory response and renal function damage, and promote postoperative recovery. Meanwhile, dexmedetomidine showcased a good safety profile and a good anesthetic outcome.展开更多

Much of the development was pursued by individuals or groups, each of which participated in adding further refinements to the implants, instruments and surgical procedures, thus minimizing the serious problems of wear, osteolysis, loosening and femoral neck fractures. The purpose of this study is to explore the development process to optimize the resurfacing total hip replacement into its current application. Methods: In the early 1980s, cementless resurfacing implants were developed using “thin shell” technology to minimize bony resection of the acetabulum and femoral head. Femoral components utilized short, non-porous coated, tapered straight stems to reduce shear stresses in the femoral neck to prevent fractures and stress shielding, while mechanically stabilizing and aligning the components. Acetabular components were anatomically designed to be recessed inside bony borders to avoid neck-cup impingement and loosening. Initially, ultrahigh molecular weight polyethylene (UHMWPE) was used as a bearing, but due to high levels of wear and osteolysis, it was replaced by wear-resistant highly crossed-linked polyethylene (HXLPE) in 2008. Results: Use of HXLPE as a bearing material in both Co-Cr-Mo and titanium nitride (TiN) ceramic-coated resurfacing implants has led to excellent patient outcomes for more than 10 years. In clinical studies, 87% of patients with bilateral total hip replacements prefer their resurfacing-type total hip over their stem-type total hip. The author’s own personal resurfacing total hips, now at 8 and 5 years, respectively, provide “normal” function and no radiographic osteolysis. Conclusions: After 45 years of active evaluation, including mechanical design considerations, prosthetic design development, clinical and radiographic analysis of results, as well as availability of components cleared by the FDA 510 K process, the author has stated a personal preference for the BP Resurfacing Hip System. His excellent mid-term results in both of his resurfaced hips are similar to the long-term results presented in published studies.展开更多

Some authors have reported performing hip replacement with different strategies with very good outcomes. This study aimed to describe the surgical outcomes and necessary conditions for total hip replacement in active hip tuberculosis. Methods: We conducted a quasi-experimental study. The study enrolled 40 patients with 42 active tuberculosis hips at stage IV treated by total hip replacement from October 2016 to December 2019 at the National Lung Hospital. We followed up with the patients for at least 12 months, evaluated surgical outcomes, and investigated the factors associated with these outcomes by logistic regression analysis. Results: Surgical outcomes showed that 37 patients (88.1%) had excellent hip function, no abscesses, and no sinus tract formation. Four cases (9.5%) had sinus tract formations. One case (2.4%) had good hip function. Binary logistic regression models revealed that sinus tract formation was associated with preoperative tuberculosis infection syndrome. The average time to obtain antituberculosis drug treatment preoperatively was 4.6 weeks. Conclusion: Total hip replacement for active hip tuberculosis is a practical and promising treatment method. Surgeons should consider improving patients’ conditions before performing total hip replacement, administering antitubercular drugs, and arthrotomy to eliminate all abscesses, and decrease the risk of tuberculosis infection syndrome and the inflammatory response.展开更多

The average age at the time of THA was 48 years(range 29 to 65 years). Erythrocyte sedimentation rate, C reactive protein, chest X-ray and contrast enhanced magnetic resonance imaging were done preoperatively to confirm resolution of the disease and to rule out any residual disease. Intra-operative samples were taken for microbiological examination, polymerase chain reaction(PCR) and histological examination. Patients were started on anti-tubercular drugs one week before the operation and continued for 6 mo post operatively. The patients were followed up clinically using the Harris hip score as well as radiologically for any loosening of the implants, osteolysis and any recurrence of tuberculosis. Any complications especially the recurrence of the infection was also recorded.RESULTS: The mean interval from completion of antitubercular therapy for tuberculosis to surgery was 4.2 years(range, 2-6 years). Preoperatively, 17 patients had ankylosis whereas 48 patients had functional but painful range of motion. The mean surgical time was 97 min(range, 65-125) whereas the mean blood loss was 600 m L(range, 400-900 m L). The average follow up was 8.3 years(range 6-11 years). The average Harris Hip score improved from 27 preoperatively to 91 at the final follow up. Seventeen patients had acetabularprotrusion which was managed with impaction grafting and cementless acetabular cup. The bone graft had consolidated in all these 17 patients at the follow up. Two patients developed discharging sinuses at 9 and 11 mo postoperatively respectively. The discharge tested positive for tuberculosis on the PCR. Both these patients were put on antitubercular therapy for another year. Both of them recovered and had no evidence of any loosening or osteolysis on X-rays. There were no other complications recorded.CONCLUSION: Total hip replacement restores good function to patients suffering from post tubercular arthritis of the hip.展开更多

Two independent reviewers evaluated the risk ratios of revision due to any cause, aseptic loosening, infection, and dislocation rate of each implants with a pre-determined form. The risk ratios were pooled separately for clinical trials, cohorts and registers before pooled altogether using fixed-effect model. Meta-regressions were performed to identify the source of heterogeneity. Funnel plots were analyzed. RESULTS Twenty-seven studies comprising 5 clinical trials, 9 cohorts, and 13 registers fulfilled the research criteria and analyzed. Compared to cementless THR, cemented THR have pooled RR of 0.47(95%CI: 0.45-0.48), 0.9(0.84-0.95), 1.29(1.06-1.57) and 0.69(0.6-0.79) for revision due to any reason, revision due to aseptic loosening, revision due to infection, and dislocation respectively. Compared to hybrid THR, the pooled RRs of cemented THR were 0.82(0.76-0.89), 2.65(1.14-6.17), 0.98(0.7-1.38), and 0.67(0.57-0.79) respectively. Compared to hybrid THR, cementless THR had RRs of 0.7(0.65-0.75), 0.85(0.49-1.5), 1.47(0.93-2.34) and 1.13(0.98-1.3).CONCLUSION Despite the limitations in this study, there was some tendency that cemented fixation was still superior than other types of fixation in terms of implant survival.展开更多

Uncemented THR was introduced to improve the long term results and in particular the results in younger, higher functioning patients. There has been controversy about the value of uncemented compared to cemented THR although there has been a world-wide trend towards uncemented fixation. Uncemented acetabular fixation has gained wide acceptance, as seen in the increasing number of hybrid THR in joint registries, but there remains debate about the best mode of femoral fixation.In this article we review the history and current worldwide registry data, with an in-depth analysis of the New Zealand Joint Registry, to determine the results of uncemented femoral fixation in an attempt to provide an evidence-based answer as to the value of this form of fixation.展开更多
文摘BACKGROUND Osteonecrosis or avascular necrosis(AVN)of the hip was one of the dreaded complications of coronavirus disease 2019(COVID-19),which emerged in patients who received steroid therapy.Corticosteroids have been a mainstay in the treatment protocol of COVID-19 patients.Popular corticosteroid drugs used in patients suffering from COVID-19 were intravenous(IV)or oral dexamethasone,methylprednisolone or hydrocortisone.The use of such high doses of corticost-eroids has shown very positive results and has been lifesaving in many cases.Still,long-term consequences were drug-induced diabetes,osteoporosis,Cushing syndrome,muscle wasting,peripheral fat mobilization,AVN,hirsutism,sleep disturbances and poor wound healing.A significant number of young patients were admitted for bilateral total hip replacements(THR)secondary to AVN following steroid use for COVID-19 treatment.AIM To assess the efficacy of bilateral pericapsular end nerve group(PENG)blocks in patients posted for bilateral THR post-steroid therapy after COVID-19 infection and assess the time taken to first ambulate after surgery.METHODS This prospective observational study was conducted between January 2023 and August 2023 at Care Hospitals,Hyderabad,India.Twenty young patients 30-35 years of age who underwent bilateral THR were studied after due consent over 8 months.All the patients received spinal anaesthesia for surgery and bilateral PENG blocks for postoperative analgesia.RESULTS The duration of surgery was 2.5 h on average.Seventeen out of twenty patients(85%)had a Visual Analog Score(VAS)of less than 2 and did not require any supplementation.One patient was removed from the study,as he required re-exploration.The remaining two patients had a VAS of more than 8 and received IV morphine post-operatively as a rescue analgesic drug.Fifteen out of seventeen patients(88.2%)could be mobilized 12 h after the procedure.CONCLUSION Osteonecrosis or AVN of the hip was one of the dreaded complications of COVID-19,which surfaced in patients who received steroid therapy requiring surgical intervention.Bilateral PENG block is an effective technique to provide post-operative analgesia resulting in early mobilization and enhanced recovery after surgery.
文摘BACKGROUND A femoral neck fracture is a common and frequently reported issue in orthopedics, with a greater rate of incidence among the elderly. Due to their advanced age and the presence of some primary diseases, both anesthesia and surgery are increasingly difficult in elderly patients with a femoral neck fractures. In fact,general anesthesia can easily induce complications such as cognitive dysfunction,which is not conducive to postoperative recovery.AIM To analyze the efficacy of dexmedetomidine in inducing anesthesia for elderly patients undergoing hip replacement surgery.METHODS A total of 98 elderly patients undergoing hip replacement in our hospital from June 2020 to June 2021 were randomly divided into control group(49 cases) and observation group(49 cases). The control group was given general anesthesia, and the observation group was combined with dexmedetomidine for anesthesia on the basis of the control group. Both groups were observed until the patients were discharged. The vital signs, serum inflammatory factors and renal function indexes of the two groups were compared before, during and 6 h after operation.The postoperative recovery and adverse events of the two groups were statistically analyzed.RESULTS Compared with the mean arterial pressure of the two groups, the intraoperative and postoperative 6 h was higher than that before the operation, the intraoperative was lower than the postoperative 6 h(P < 0.05);the blood oxygen saturation of the two groups was higher than that before operation and 6 h after operation, and the observation group was higher than the control group 6 h after operation(P < 0.05). The heart rate of the two groups was lower during and 6 h after operation than that before operation, and higher at 6 h after operation than that during operation(P < 0.05).The levels of serum C-reactive protein, tumor necrosis factor-α, interleukin-1β and kidney injury molecule-1 in the two groups were higher during operation and 6 h after operation than those before operation(P < 0.05). The level of serum urea nitrogen in the two groups was higher than that before operation, and that in the observation group was lower than that in the control group(P < 0.05). During hospitalization, the first time of getting out of bed, recovery time of grade Ⅱ muscle strength, recovery time of grade Ⅲ muscle strength and hospitalization time in the observation group were shorter than those in the control group(P < 0.05).CONCLUSION Dexmedetomidine can effectively improve the vital signs of elderly patients undergoing hip replacement surgery, reduce the body’s inflammatory response and renal function damage, and promote postoperative recovery. Meanwhile, dexmedetomidine showcased a good safety profile and a good anesthetic outcome.
文摘BACKGROUND Trochanteric bursitis is a common complication following total hip replacement(THR),and it is associated with high level of disability and poor quality of life.Excision of the trochanteric bursa prophylactically during THR could reduce the occurrence of post-operative trochanteric bursitis.AIM To evaluate whether synchronous trochanteric bursectomy at the time of THR affects the incidence of post-operative trochanteric bursitis.METHODS This retrospective cohort study was conducted in the secondary care setting at a large district general hospital.Between January 2010 and December 2020,954 patients underwent elective primary THR by two contemporary arthroplasty surgeons,one excising the bursa and the other not(at the time of THR).All patients received the same post-operative rehabilitation and were followed up for 1 year.We reviewed all cases of trochanteric bursitis over this 11-year period to determine the incidence of post-THR bursitis.Two proportion Z-test was used to compare incidences of trochanteric bursitis between groups.RESULTS 554 patients underwent synchronous trochanteric bursectomy at the time of THR whereas 400 patients did not.A total of 5 patients(incidence 0.5%)developed trochanteric bursitis following THR;4 of whom had undergone bursectomy as part of their surgical approach,1 who had not.There was no statistically significant difference between the two groups(Z value 1.00,95%CI:-0.4%to 1.3%,P=0.32).There were also 8 other patients who had both trochanteric bursitis and hip osteoarthritis prior to their THR;all of whom were treated with THR and synchronous trochanteric bursectomy,and 7 had resolution of their lateral buttock pains but 1 did not.CONCLUSION Synchronous trochanteric bursectomy during THR does not materially affect the incidence of post-operative bursitis.However,it is successful at treating patients with known trochanteric bursitis and osteoarthritis requiring THR.
文摘Background: Resurfacing-type total hip replacement (THR) has been successfully developed over the past 50 years through collaborative efforts between engineers and surgeons. Much of the development was pursued by individuals or groups, each of which participated in adding further refinements to the implants, instruments and surgical procedures, thus minimizing the serious problems of wear, osteolysis, loosening and femoral neck fractures. The purpose of this study is to explore the development process to optimize the resurfacing total hip replacement into its current application. Methods: In the early 1980s, cementless resurfacing implants were developed using “thin shell” technology to minimize bony resection of the acetabulum and femoral head. Femoral components utilized short, non-porous coated, tapered straight stems to reduce shear stresses in the femoral neck to prevent fractures and stress shielding, while mechanically stabilizing and aligning the components. Acetabular components were anatomically designed to be recessed inside bony borders to avoid neck-cup impingement and loosening. Initially, ultrahigh molecular weight polyethylene (UHMWPE) was used as a bearing, but due to high levels of wear and osteolysis, it was replaced by wear-resistant highly crossed-linked polyethylene (HXLPE) in 2008. Results: Use of HXLPE as a bearing material in both Co-Cr-Mo and titanium nitride (TiN) ceramic-coated resurfacing implants has led to excellent patient outcomes for more than 10 years. In clinical studies, 87% of patients with bilateral total hip replacements prefer their resurfacing-type total hip over their stem-type total hip. The author’s own personal resurfacing total hips, now at 8 and 5 years, respectively, provide “normal” function and no radiographic osteolysis. Conclusions: After 45 years of active evaluation, including mechanical design considerations, prosthetic design development, clinical and radiographic analysis of results, as well as availability of components cleared by the FDA 510 K process, the author has stated a personal preference for the BP Resurfacing Hip System. His excellent mid-term results in both of his resurfaced hips are similar to the long-term results presented in published studies.
文摘BACKGROUND The popularity of uncemented stems in revision total hip arthroplasty(THA)has increased in the last decade.AIM To assess the outcomes of both cemented and uncemented stems after mid-term follow up.METHODS This study was performed following both the Preferred Reporting Items for Systematic Reviews and Meta-analyses Statement and the Cochrane Handbook for systematic reviews and meta-analysis guidelines.Articles were chosen irrespective of country of origin or language utilized for the article full texts.This paper included studies that reviewed revision THA for both cemented or uncemented long stems.RESULTS Three eligible studies were included in the meta-analysis.Analysis was conducted by using Review Manager version 5.3.We computed the risk ratio as a measure of the treatment effect,taking into account heterogeneity.We used random-effect models.There were no significant differences found for intraoperative periprosthetic fractures[risk ratio(RR)=1.25;95%confidence interval(CI):0.29-5.32;P=0.76],aseptic loosening(RR=2.15,95%CI:0.81-5.70;P=0.13),dislocation rate(RR=0.50;95%CI:0.10-2.47;P=0.39),or infection rate(RR=0.99,95%CI:0.82-1.19;P=0.89),between the uncemented and the cemented long stems for revision THA after mid-term follow-up.CONCLUSION This study has evaluated the mid-term outcomes of both cemented and uncemented stems at first-time revision THA.In summary,there were no significant differences in the dislocation rate,aseptic loosening,intraoperative periprosthetic fracture and infection rate between the two cohorts.
文摘BACKGROUND Total hip replacements(THR)and total knee replacements(TKR)are effective treatments for severe osteoarthritis(OA).Some studies suggest clinical outcomes following THR are superior to TKR,the reason for which remains unknown.This study compares clinical outcomes between THR and TKR.AIM To compare the clinic outcomes of THR anad TKR using a comprehensive range of patient reported outcome measures(PROMs).METHODS A prospective longitudinal observational study of patients with OA undergoing THR and TKR were evaluated using a comprehensive range of generic and joint specific PROMs pre-and post-operatively.RESULTS A total of 131 patients were included in the study which comprised the THR group(68 patients)and the TKR group(63 patients).Both groups demonstrated significant post-operative improvements in all PROM scores(P<0.001).There were no significant differences in post-operative PROM scores between the two groups:Hip and Knee Osteoarthritis Outcome scores(P=0.140),Western Ontario and McMaster Universities Osteoarthritis Index pain(P=0.297)stiffness(P=0.309)and function(P=0.945),Oxford Hip and Knee Score(P=0.076),EuroQol-5D index(P=0.386)and Short-Form 12-item survey physical component score(P=0.106).Subgroup analyses showed no significant difference(P>0.05)between cruciate retaining and posterior stabilised prostheses in the TKR group and no significant difference(P>0.05)between cemented and uncemented fixation in the THR group.Obese patients had poorer outcomes following TKR but did not significantly influence the outcome following THR.CONCLUSION Contrary to some literature,THR and TKR are equally efficacious in alleviating the pain and disability of OA when assessed using a comprehensive range of PROMs.The varying knee prosthesis types and hip fixation techniques did not significantly influence clinical outcome.Obesity had a greater influence on the outcome following TKR than that of THR.
文摘Objective:To evaluate the effect of the clinical nursing pathway applied to functional exercise in patients with hip replacements before and after the operation.Methods:The China National Knowledge Infrastructure(CNKI),WanFang Data,Chinese science and technology journal database(VIP),PubMed,Web of Science,EMBASE,CBM and the Cochrane Library(2015-5) were searched for randomized controlled trials(RCTs) on clinical nursing pathways for functional exercise in patients with hip replacements before and after surgery from June 2015 to January2010.The references included in the literature were also retrieved.To meet the literature standard,2reviewers independently selected and extracted data according to the inclusion criteria and assessed the risks of bias.RevMan 5.3 software was used in this meta-analysis.The quality of evidence was evaluated using grade profiler3.6 software,the level recommended for grading.Results:A total of 15 RCTs and 1248 patients were included.The meta-analysis showed that,in the clinical nursing path group,the Harris score of hip function[SMD = 3.35,95%CI(2.53.4.16),P < 0.00001]and incidence of thrombosis embolism[RR = 0.28,95%CI(0.15,0.53),P < 0.0001],pulmonary infection[RR = 0.33,95%CI(0.14,0.82),P = 0.02],urinary retention[RR = 0.22,95%CI(0.09.0.52),P = 0.0005],constipation[RR = 0.20,95%CI(0.10,0.40),P < 0.00001],patients' satisfaction for nursing care[RR = 1.26,95%CI(1.17,1.36),P< 0.000011 and shortened hospitalization times[SMD =-1.91,95%CI(-2.39.-1.43),P < 0.0001[were statistically significantly better than those in the control group.However,in reducing joint dislocations[RR- 0.25,95%CI(0.05,1.15),P = 0.08],pressure ulcers[RR = 0.25,95%CI(0.03,2.19),P=0.21],and incidence of complications[RR = 0.42,95%CI(0.15.1.12),P = 0.08],there was no statistically significant difference between the two groups.Funnel plot analysis of the average length of stay showed that there might be some publication bias in the literature.The GRADE evaluation results showed that the level of Harris scores for hip function was moderate and the incidence of thrombosis,urinary retention and satisfaction of patients regarding nursing were low,and the rest of the factors analyzed were very low.Conclusions:The effect of the clinical nursing pathway applied to functional exercises in patients with hip replacements before and after surgery was significantly better than that of routine nursing.However,it was restricted by the evaluation grade of the research results and the standardization and uniformity of the research.The results of the above study need to be verified by more high-quality RCTs.
文摘BACKGROUND By analyzing the risk factors of postoperative complications in elderly patients with hip replacement,We aimed to develop a nomogram model based on preoperative and intraoperative variables and verified the sensitivity and specificity for risk stratification of postoperative complications in elderly with total hip replacement patients.AIM To develop a nomogram model for risk stratification of postoperative complications in elderly with total hip replacement patients.METHODS A total of 414 elderly patients who underwent surgical treatment for total hip replacement hospitalized at the Affiliated Hospital of Guangdong Medical University from March 1,2017 to August 31,2019 were included into this study.Univariate and multivariate logistic regression were conducted to identify independent risk factors of postoperative complication in the 414 patients.A nomogram was developed by R software and validated to predict the risk of postoperative complications.RESULTS Multivariate logistic regression analysis revealed that age(OR=1.05,95%CI:1.00-1.09),renal failure(OR=0.90,95%CI:0.83-0.97),Type 2 diabetes(OR=1.05,95%CI:1.00-1.09),albumin(ALB)(OR=0.91,95%CI:0.83-0.99)were independent risk factors of postoperative complication in elderly patients with hip replacement(P<0.05).For validation of the nomogram,receive operating characteristic curve revealed that the model predicting postoperative complication in elderly patients with hipreplacement was the area under the curve of 0.8254 (95%CI: 0.78-0.87), the slope of the calibrationplot was close to 1 and the model passed Hosmer-Lemeshow goodness of fit test (χ^(2) = 10.16, P =0.4264), calibration in R E_(max) = 0.176, E_(avg) = 0.027, which all demonstrated that the model was ofgood accuracy.CONCLUSIONThe nomogram predicting postoperative complications in patients with total hip replacementconstructed based on age, type 2 diabetes, renal failure and ALB is of good discrimination andaccuracy, which was of clinical significance.
文摘BACKGROUND Total hip replacement has become one of the most successful orthopaedic procedures.The length of the femoral stem constitutes one of the most important geometrical and mechanical features of the prosthesis.Several different implants are currently available but data are limited concerning the clinical results for some of these implants.AIM To report the short-term clinical and radiological results of a novel squared section,tapered design–with four conicity-short stem in total hip replacement.METHODS This is a retrospective study of a prospectively collected data using of MINIMA?short stem in 61 consecutive patients with at least 1 year follow-up.The collected data included patients’demographics,type of arthritis,bone morphology,perioperative data,clinical results using Harris Hip Score,EuroQol(EQ-5D),pain score and satisfaction rate,complications and radiological results.RESULTS Total 61 patients were included in our study with a mean age of 56 years of age(range 25-73 years).The majority of them(68.6%)were women,thirty seven patients(56.9%)were less than 60 years of age and almost half of patients(45.1%)suffered from secondary osteoarthritis(hip dysplasia,osteonecrosis,etc.).The mean time of follow-up examination was 33.4 mo(2.8 years)with a range of 12-57 months(1-4.8 years).In 35 patients(56.9%)the follow-up examination was more than 3 years.No major complications such as revision,periprosthetic fracture,dislocation or infection were presented.Re-admission 90 d postoperatively or laterwas deemed unnecessary for any reason regarding the operation.Respectively,the mean pain score,mean Harris hip score,and mean EQ-5D were improved from 6.3,58.7 and 77.3 preoperatively to 0.1,95.1,and 79.8 postoperatively.The Satisfaction rate at the final follow-up was 9.9(SD 0.3,range 8.0-10.0).All stems were classified as stable bone ingrowth and no radiolucent lineswere revealed in any of the modified Gruens’zone at the postoperative Xrays.Stem subsidence was within acceptable limits and the incidence of distal cortical hypertrophy was relatively low.CONCLUSION The clinical and radiological results concerning the MINIMA?short stem are excellent according to this first report of this specific design of the short femoral stems.Because of the small number of cases and short-term follow-up of this study,a longer follow up time and more patients’enrollment is required.

文摘Objectives: Femoral neck fractures are becoming more common within nowadays. This research is to explore the clinical effect of primary total hip replacement (THA) via direct anterior approach (DAA) and posterolateral approach (PLA) in the treatment of femoral neck fracture. Methods: Retrospective analysis of 100 cases of elderly patients with femoral neck fracture who underwent total hip arthroplasty admitted to Tianyou Hospital affiliated to Wuhan University of Science and Technology from January 2019 to January 2022. 50 patients treated with DAA approach were included in the observation group, and 50 patients treated with PLA approach were included in the control group. The operation indexes, postoperative acetabular abduction angle and anteversion angle, hip joint function, Harris score and complications were compared between the two groups. Result: The length of incision in the observation group was shorter than that in the control group, and the amount of intraoperative bleeding and postoperative hospital stay were shorter than those in the control group (P < 0.05);There was a statistically significant difference between the two groups in the ratio of acetabular abduction angle and its safe zone, and the length difference of both lower limbs (P < 0.05), while there was no statistically significant difference between the two groups in the ratio of acetabular anteversion angle and its safe zone, eccentricity, and its recovery rate (P > 0.05);Harris score of hip joint: 6 months after operation, the anterior approach group was significantly higher than the posterolateral approach group (P < 0.05), and there was no statistical difference between the two groups 12 months after operation (P > 0.05);The total incidence of complications in the observation group was lower than that in the control group, with a statistically significant difference (P Conclusion: DAA and PLA approaches for total hip replacement can restore the hip joint structure of patients with femoral neck fractures and achieve good results, but DAA approach has greater advantages in early postoperative recovery, improvement of hip joint function, small surgical injury, high application value, so it is recommended.
文摘Background: Treatment of hip disorders during active hip tuberculosis has long been a controversial issue. Some authors have reported performing hip replacement with different strategies with very good outcomes. This study aimed to describe the surgical outcomes and necessary conditions for total hip replacement in active hip tuberculosis. Methods: We conducted a quasi-experimental study. The study enrolled 40 patients with 42 active tuberculosis hips at stage IV treated by total hip replacement from October 2016 to December 2019 at the National Lung Hospital. We followed up with the patients for at least 12 months, evaluated surgical outcomes, and investigated the factors associated with these outcomes by logistic regression analysis. Results: Surgical outcomes showed that 37 patients (88.1%) had excellent hip function, no abscesses, and no sinus tract formation. Four cases (9.5%) had sinus tract formations. One case (2.4%) had good hip function. Binary logistic regression models revealed that sinus tract formation was associated with preoperative tuberculosis infection syndrome. The average time to obtain antituberculosis drug treatment preoperatively was 4.6 weeks. Conclusion: Total hip replacement for active hip tuberculosis is a practical and promising treatment method. Surgeons should consider improving patients’ conditions before performing total hip replacement, administering antitubercular drugs, and arthrotomy to eliminate all abscesses, and decrease the risk of tuberculosis infection syndrome and the inflammatory response.
文摘Objective:To explore the effect of functional exercise nursing plan based on evidence-based nursing in patients after hip replacement.Methods:A total of 150 patients who underwent hip replacement in the orthopedic second ward of our hospital during the research period from January 2010 to January 2020 were selected as the research object.The random number expression method was applied to achieve grouping of patients.Among them,the control group received conventional rehabilitation treatment;the experimental group guided rehabilitation exercises according to the functional exercise nursing plan after hip replacement,and the rehabilitation conditions of the two groups were compared.Results:Compared with the patients in the control group,the bed time(7.45±2.10)days and average hospital stay(15.84±3.29)of the experimental group were relatively shorter.The incidence of complications in the experimental group and the control group was 6.67%and 16.00%,which are significantly different.The difference in Harris hip score before surgery was small,and the difference when discharge and after discharge was gradually increased,showing a better care effect in the experimental group.There was no significant difference in preoperative quality of life scores between the two groups before surgery(P>0.05).The life quality of the experimental group was significantly higher than that of the control group at discharge,1 month after discharge and 3 months after discharge,and showed most significantly after 3 months.Conclusion:The effect of functional exercise nursing plan based on evidence-based nursing in patients after hip replacement is remarkable,which can promote the recovery of patients,improve the quality of life,reduce the hospitalization time,reduce the incidence of postoperative complications,and has a positive significance in promoting clinical development in China.
文摘Objective To explore the causes and management of prosthesis disocation after artificaial hip replacement (AHR).Methods Seventeen patients with prosthesis dislocation after AHR during January 2000 to July 2010 were studied
文摘AIM: To present the results of total hip arthroplasty(THA) for post tubercular arthritis of the hip joint.METHODS: Sixty-five patients(45 male, 20 female) with previously treated tuberculosis of the hip joint underwent cementless THA for post tubercular arthritis. The average age at the time of THA was 48 years(range 29 to 65 years). Erythrocyte sedimentation rate, C reactive protein, chest X-ray and contrast enhanced magnetic resonance imaging were done preoperatively to confirm resolution of the disease and to rule out any residual disease. Intra-operative samples were taken for microbiological examination, polymerase chain reaction(PCR) and histological examination. Patients were started on anti-tubercular drugs one week before the operation and continued for 6 mo post operatively. The patients were followed up clinically using the Harris hip score as well as radiologically for any loosening of the implants, osteolysis and any recurrence of tuberculosis. Any complications especially the recurrence of the infection was also recorded.RESULTS: The mean interval from completion of antitubercular therapy for tuberculosis to surgery was 4.2 years(range, 2-6 years). Preoperatively, 17 patients had ankylosis whereas 48 patients had functional but painful range of motion. The mean surgical time was 97 min(range, 65-125) whereas the mean blood loss was 600 m L(range, 400-900 m L). The average follow up was 8.3 years(range 6-11 years). The average Harris Hip score improved from 27 preoperatively to 91 at the final follow up. Seventeen patients had acetabularprotrusion which was managed with impaction grafting and cementless acetabular cup. The bone graft had consolidated in all these 17 patients at the follow up. Two patients developed discharging sinuses at 9 and 11 mo postoperatively respectively. The discharge tested positive for tuberculosis on the PCR. Both these patients were put on antitubercular therapy for another year. Both of them recovered and had no evidence of any loosening or osteolysis on X-rays. There were no other complications recorded.CONCLUSION: Total hip replacement restores good function to patients suffering from post tubercular arthritis of the hip.
文摘AIM To determine whether cemented, cementless, or hybrid implant was superior to the other in terms of survival rate.METHODS Systematic searches across MEDLINE, CINAHL, and Cochrane that compared cemented, cementless and hybrid total hip replacement(THR) were performed. Two independent reviewers evaluated the risk ratios of revision due to any cause, aseptic loosening, infection, and dislocation rate of each implants with a pre-determined form. The risk ratios were pooled separately for clinical trials, cohorts and registers before pooled altogether using fixed-effect model. Meta-regressions were performed to identify the source of heterogeneity. Funnel plots were analyzed. RESULTS Twenty-seven studies comprising 5 clinical trials, 9 cohorts, and 13 registers fulfilled the research criteria and analyzed. Compared to cementless THR, cemented THR have pooled RR of 0.47(95%CI: 0.45-0.48), 0.9(0.84-0.95), 1.29(1.06-1.57) and 0.69(0.6-0.79) for revision due to any reason, revision due to aseptic loosening, revision due to infection, and dislocation respectively. Compared to hybrid THR, the pooled RRs of cemented THR were 0.82(0.76-0.89), 2.65(1.14-6.17), 0.98(0.7-1.38), and 0.67(0.57-0.79) respectively. Compared to hybrid THR, cementless THR had RRs of 0.7(0.65-0.75), 0.85(0.49-1.5), 1.47(0.93-2.34) and 1.13(0.98-1.3).CONCLUSION Despite the limitations in this study, there was some tendency that cemented fixation was still superior than other types of fixation in terms of implant survival.
文摘Total hip replacement(THR) is a successful and reliable operation for both relieving pain and improving function in patients who are disabled with end stage arthritis.The ageing population is predicted to significantly increase the requirement for THR in patients who have a higher functional demand than those of the past. Uncemented THR was introduced to improve the long term results and in particular the results in younger, higher functioning patients. There has been controversy about the value of uncemented compared to cemented THR although there has been a world-wide trend towards uncemented fixation. Uncemented acetabular fixation has gained wide acceptance, as seen in the increasing number of hybrid THR in joint registries, but there remains debate about the best mode of femoral fixation.In this article we review the history and current worldwide registry data, with an in-depth analysis of the New Zealand Joint Registry, to determine the results of uncemented femoral fixation in an attempt to provide an evidence-based answer as to the value of this form of fixation.
