人工髋关节翻修术86例临床分析

目的：评价人工髋关节翻修术的临床疗效并探讨相关影响因素。方法：人工髋关节置换病例86例髋（对所有患者进行问卷调查、髋关节功能检查，并进行术前、术后Harris评分，术后疼痛发生评估及X线分析。结果：所有病例均获随访8个月～6年，平均38．9个月，无感染、假体松动等症发生；髋关节活动范围明显改善，Harris评分术前平均42分（30～53分），随访时平均89分（73～97分），其中优51，良29例，可6例，优良率93．02％；X线评价：无假体移位下沉等不稳现象，假体周围均无新出现的透亮带。结论：人工节翻修术近期疗效显著；髋关节翻修术中髋臼重建需充分术前准备，术中选择合适的假体及植骨方式。

Clinical analysis on 86 cases of artificial hip joint overhauling

Objective：To analyze total hip arthroplasty revision reasons, evaluation of its clinical efficacy, and to explore factors of affecting efficacy. Methods： Choose 86 cases in our department having accepted hip arthroplasty revision in past. Through a questionnaire survey of all patients, hip function tests,preoperative and postoperative Harris hip score,occurrence of postoperative pain assessment and X-ray analysis to obtain clinical efficacy evidence. Results：All patients were followed up for 8 months to 6 years（an average of 38.9 months）.In all of the patients,no infection, prosthesis loosening and other complications occurred;hip range of motion compared with the preoperative improved significantly,Harris hip score preoperative average of 42 points （30 to 53 minutes）,while average of 89 points （73 to 97 minutes）to follow-up time,which were excellent in 51 cases, good in 29 cases, fair in 6 cases, good rate together accounted for 93.02%;X-line assessment：no prosthesis subsidence displacement instability phenomena such as loosening, no new translucent band appeared around periprosthetic, transplanting bone healed well. Conclusion： The short-term effect of artificial hip arthroplasty revision;acetabular reconstruction needs to be fully prepared before surgery, the right prosthesis and bone transplant methods needs to be choosen.
