Patients with acute femoral neck fractures, treated with prosthetic replacement (Christiansen's trunnion bearing endoprosthesis), were followed up at 15 months and again at 67 months postoperatively, and the results of the two examinations have been compared. The patients' personal opinion of the results of the operation did not change between the time of the first and second follow-up examinations. However, the objective results showed a deterioration in function (according to Stinchfield's hip assessment scheme) with increasing follow-up time. This deterioration in rating was mostly caused by reduced walking ability. X-ray study of the hips showed an increasing frequency of acetabular protrusion, and settling and loosening of the prosthetic stem. No clear correlation between X-ray findings and clinical results could be found. We conclude that the serviceability of the prosthetic operation is apparently good despite the objective evidence of progressive deterioration both in the grading of the results and in the X-ray findings.
对采用假体置换（克里斯蒂安森耳轴支撑型人工关节）治疗的急性股骨颈骨折患者，在术后15个月及67个月时进行随访，并对两次检查结果进行比较。患者对手术结果的个人看法在第一次和第二次随访检查期间没有改变。然而，客观结果显示，随着随访时间的延长，功能（根据斯廷奇菲尔德髋关节评估方案）出现恶化。这种评分恶化主要是由于行走能力下降所致。髋关节X线检查显示髋臼突出、假体柄下沉和松动的频率增加。未发现X线表现与临床结果之间存在明显相关性。我们得出结论，尽管在结果分级和X线表现方面都有客观证据表明病情在逐渐恶化，但假体手术的适用性显然良好。
