本文介绍新生儿髋关节的超声解剖和先天性髋关节脱位的B超早期诊断方法。1083名新生儿两侧艘关节B超检查,发现先天性髋关节半脱位1例。在髋关节冠状面声像图上分别测量新生儿髋关节的a角、a角、髋臼指数和股骨头骨性髋臼覆盖率,其正常值分别为:65.10±5.10°、40.27°±16.14°、24.75°±4.29°、64.66±5.63%(平均值±标准差)。研究结果表明:B超能早期发现先天性髋关节脱位及发育不良,操作简单、经济、无痛、无放射性损害。

The average age of the patients at the surgery was 64.7 years. Sixty cases were treated with Austin-Moore prosthesis. 96.8% of the patients had excellent or good results at the final follow up study.

Of 90 cases underwent hemiarthroplasty for femoral neck fracture from 1980 to 1985, 62 cases were followed up more than 8 years, with an average of ten years and seven months. The average age of the patients at the surgery was 64.7 years. Sixty cases were treated with Austin-Moore prosthesis. 96.8% of the patients had excellent or good results at the final follow up study. Radiological examinations showed that 19 cases had perfect acetabula, 15 cases had acetabular osteophytes and only 3 cases (8.1%) had pelvic central protrusion. Thirty cases had serial roentgenograms, there were 21 cases(70%) with stem sinking. The long term results indicate that hemiarthroplasty does not cause acetabular erosion. Acetabular osteophytes is related to weight bearing, while acetabular erosion is possibly due to unsuitable prostheses selection.

作者1980~1985年主要以Austin-Moore型人工股骨头治疗90例股骨颈骨折。随诊8年以上62例,手术时平均年龄64.7岁,平均随诊10年7个月,疗效满意率96.8%。37例X线片检查:19例髋臼完好,15例髋臼缘骨质增生,中心性脱位3例占8.1%。30例有系列X线片者,下沉21例占70%,多数为轻度下沉。随诊结果说明:单极人工股骨头长期使用并不造成中心性脱位,髋臼缘骨质增生与负重使用相关,中心性脱位与头臼比例不当,应力集中相关。

Since May 1983, coralline hip arthroplasty was performed on 60 hips (54 cases). Porous total hip arthroplasty (THA) was used in 40 hips (34 cases), and hemi arthroplasty in 20 hips (20 cases). The average follow up period of porous THA was 83.9 months (6 months to 10 years). Good results were achieved in 85.1% of the patients. Four hips (14.8%) had loosening of the femoral components, and two hips (7.4%) had loosening of the acetabular components. Analysis of the clinical data revealed that, femoral...

Since May 1983, coralline hip arthroplasty was performed on 60 hips (54 cases). Porous total hip arthroplasty (THA) was used in 40 hips (34 cases), and hemi arthroplasty in 20 hips (20 cases). The average follow up period of porous THA was 83.9 months (6 months to 10 years). Good results were achieved in 85.1% of the patients. Four hips (14.8%) had loosening of the femoral components, and two hips (7.4%) had loosening of the acetabular components. Analysis of the clinical data revealed that, femoral component loosening was due to unstable contact of the prothesis with bone, which including unsuitable prothesis or reamer was used. The reamer should be smaller than the prothesis to minimize the space between the prothesis and medullary cavity. In cases of hip dysplasia, the author recommends placing the acetabular component more proximal instead of a lateral position to the center of the hip. The author no longer advocates the use of bone graft for acetabular reconstruction.

自1983年至今应用珊瑚型人工髋关节置换术共54例60髋。其中人工全髋关节置换术34例40髋,人工股骨头置换术20例20髋。在54例60髋珊瑚型人工髋关节置换术中,有37髋随访6个月~13年,平均随访时间约7年,疗效满意率为85.1%,其中假体松动4例占14.8%,髋臼松动2例7.4%。假体松动原因是假体与股骨负重界面之间没有达到稳定接触,假体与髓腔形状不相匹配,修整髓腔松质骨时,髓腔扩大器应比假体小一号,避免假体与界面存留缝隙。对于髋臼发育不良的患者应避免髋关节旋转中心向外侧移位,应向内上方加深髋臼以减少水平移位距离,其次髋臼植骨加盖勿在负重区。
