Total Hip Replacement in Inflammatory Hip Disease using the Charnley Prosthesis

The Charnley low-friction arthroplasty was performed on 73 hips in 55 patients with inflammatory joint disease, usually for intolerable pain. Sixty-five of these operations were reviewed at a special clinic or by postal questionnaire; 57 hips were painfree or gave rise to only occasional discomfort, in 58 there was an increased range of movement, and in 46 of the 59 hips assessed clinically, the results were excellent or good. The most serious complication was deep infection, which occurred in 7 operations.

Total Hip Replacement in Osteoarthrosis using the Charnley Prosthesis

Charnley low-friction arthroplasty was performed on 352 osteoarthritic hips, usually because of severe pain. Three hundred and twenty hips were reviewed at a special follow-up clinic or by postal questionnaire.

Outcome of Hemiarthroplasty and Total Hip Replacement for Active Elderly Patients with Displaced Femoral Neck Fractures: A Meta-Analysis of 8 Randomized Clinical Trials

Background

Displaced fracture of the femoral neck has been a common clinical problem, especially in aged patients. However, the optimal treatment choice remains controversial. The purpose of this study is to conduct a systematic review of randomized clinical trials assessing the results of hemiarthroplasty and total hip replacement in patients undergoing either alternative using meta-analysis.

Methods

A literature search for randomized clinical trials was conducted through Medline, Embase and Cochrane library between 1969 and 2013 with no restrictions. Additional relevant articles were referred as source of information by way of manual searches on major orthopedic journals. Upon the search, two authors independently evaluated study quality and relevant data was extracted.

Results

A total of 8 studies with 983 patients were included in this meta-analysis. After pooling the available data, a significant dominance of Harris hip score was found for total hip replacement compared with hemiarthroplasty (SMD: −7.11, 95%:−10.70,−3.53) one year postoperatively and the advantage kept over (SMD: −6.91, 95%:−12.98, −0.85) two years after surgery. A trend toward a higher dislocation rate was found in total hip replacement group (RR: 0.46, 95%: 0.21, 1.02), of which the difference was considered insignificant. The risk of revision in group hemiarthroplasty appeared to be more than two folds higher than that after total hip replacement (RR: 4.14, 95%CI: 2.09, 8.19).

Conclusion

Even though there is a higher rate of dislocation after total hip replacement, this disadvantage could be accounted for, on the basis of a better functional score and the lower revision rate. However, from the results, it stands to reason that total hip replacement should be strongly suggested in elderly active patients with femoral neck fracture.     

髋关节置换术对股骨头坏死患者髋关节Harris评分及运动功能的影响

目的:分析髋关节置换术对股骨头坏死(osteonecrosis of the femoral head,ONFH)患者的髋关节Harris功能评分(Harris hip score,HHS)与简式Fugl-Meyer运动功能评分(Fugl-Meyer assessment scale,FMA)的影响。方法:回顾性选取于我院受诊的ONFH患者87例,按照其所用术式的不同,分为两组,传统组采用传统股骨头置换术治疗,共43例病例;研究组采用无柄解剖型人工髋关节置换术治疗,共44例,比较两组Harris评分、Fugl-Meyer运动功能评分的改变及统计并发症信息。结果:研究组Harris评分无显著差异(P0.05);治疗后,研究组Harris评分明显高于传统组(P0.05);研究组简式Fugl-Meyer运动功能显著优于传统组(P0.05);研究组并发症的发生率低于传统组(P0.05)。结论:无柄解剖型人工髋关节置换术治疗ONFH的临床疗效显著,能够改善患者髋关节功能及运动功能。     

Concentration of Wear Products in Hair,Blood, and Urine after Total Hip Replacement

Raised levels of cobalt and chromium are found in the blood and urine of patients with metallic total hip replacements. When one of the hip components is made of polyethylene much less metal seems to be released from the joint. The long-term effects of the accumulation of chromium in the body need to be studied further.     

Total Hip Replacement for the Treatment of End Stage Arthritis of the Hip: A Systematic Review and Meta-Analysis

Background

Evolvements in the design, fixation methods, size, and bearing surface of implants for total hip replacement (THR) have led to a variety of options for healthcare professionals to consider. The need to determine the most optimal combinations of THR implant is warranted. This systematic review evaluated the clinical effectiveness of different types of THR used for the treatment of end stage arthritis of the hip.

Methods

A comprehensive literature search was undertaken in major health databases. Randomised controlled trials (RCTs) and systematic reviews published from 2008 onwards comparing different types of primary THR in patients with end stage arthritis of the hip were included.

Results

Fourteen RCTs and five systematic reviews were included. Patients experienced significant post-THR improvements in Harris Hip scores, but this did not differ between impact types. There was a reduced risk of implant dislocation after receiving a larger femoral head size (36 mm vs. 28 mm; RR = 0.17, 95% CI: 0.04, 0.78) or cemented cup (vs. cementless cup; pooled odds ratio: 0.34, 95% CI: 0.13, 0.89). Recipients of cross-linked vs. conventional polyethylene cup liners experienced reduced femoral head penetration and revision. There was no impact of femoral stem fixation and cup shell design on implant survival rates. Evidence on mortality and complications (aseptic loosening, femoral fracture) was inconclusive.

Conclusions

The majority of evidence was inconclusive due to poor reporting, missing data, or uncertainty in treatment estimates. The findings warrant cautious interpretation given the risk of bias (blinding, attrition), methodological limitations (small sample size, low event counts, short follow-up), and poor reporting. Long-term pragmatic RCTs are needed to allow for more definitive conclusions. Authors are encouraged to specify the minimal clinically important difference and power calculation for their primary outcome(s) as well CONSORT, PRISMA and STROBE guidelines to ensure better reporting and more reliable production and assessment of evidence.     

全髋和半髋置换治疗老年股骨颈骨折的临床对比分析

目的:探讨全髋和半髋关节置换术治疗老年股骨颈骨折的临床疗效。方法:选择本院收治的70例老年股骨颈骨折患者,采用随机数字表法将其分为观察组和对照组各35例,观察组给予全髋关节置换术,对照组予以半髋关节置换术,对比两组所用手术时间、术中出血量、术后Harris评分及髋关节功能、术后并发症、疼痛率及翻修率。结果:观察组手术时间为(113.6±19.3)min,术中出血量为(432.1±32.7)ml,均显著高于对照组的(73.1±10.2)min、(201.3±30.1)m L,两组比较差异均有统计学意义(均P0.05);观察组髋关节功能总优良率、Harris评分分别为91.43%,(91.13±5.09)分,显著优于对照组的77.14%、(80.15±4.71)分,两组比较差异均有统计学意义(均P0.05);观察组不良反应发生率及翻修率分别为20.00%、0.00%,低于对照组的22.85%、5.71%,但差异均无统计学意义(均P0.05);观察组疼痛率为5.71%,显著低于对照组的25.71%,两组比较差异有统计学意义(P0.05)。结论:两种术式对股骨颈骨折的老年患者均能起到有效的治疗,均有各自的优缺点,对疼痛较为敏感和活动较多的老年患者而言,宜采用全髋关节置换术。
