文题释义:
人工髋关节:假体仿照人体髋关节的结构,将假体柄部插入股骨髓腔内,利用头部与关节臼或假体金属杯形成旋转,实现股骨的曲伸和运动。一般情况下,假体柄分别采用钛合金、钴铬钼合金、超低碳不锈钢材料制造,髋臼采用无毒超高分子聚乙烯制造,金属球头采用钛合金(与钛合金、钴铬钼合金股骨头柄配合)和超低碳不锈钢材料制造。
人工髋关节置换术后翻修:针对第一次关节置换手术,取出臼杯、假体柄或者两者均取出称之为翻修手术,翻修原因包括假体的无菌性松动、假体周围感染、假体断裂、假体周围骨折等。
 
摘要
背景:经查阅文献发现,炎性假瘤引起的髋关节置换翻修术相关的研究较少。
目的:旨在随访观察金对金髋关节置换失败伴有炎性假瘤患者翻修术后预后情况,并分析其翻修术后预后的影响因素。
方法:收集81例拟行髋关节置换翻修术患者既往医疗记录、基线资料及初次置换手术信息,完善术前检查行翻修术后,利用HSS评分评估术后关节功能,行影像学检查评估假体情况,测定血清钴铬离子浓度,统计术后并发症发生情况,统计分析并发症的影响因素。
结果与结论:①患者翻修术后关节评分显著上升(P=0.000);血清钴铬离子浓度显著下降(P=0.000);②翻修术后并发症发生率为16%,术后再翻修率为6%;③术前假体松动(P=0.012)、MRI检查提示组织硬化(P=0.000)、术中组织损伤分级较高(P=0.049)等因素与翻修术后并发症相关;④KM生存曲线提示术后30个月时假体存活率为88%;⑤结果提示,金对金髋关节置换失败患者翻修术后总体预后较差,预后危险因素包括术前无菌性松动、关节周围组织硬化、翻修术中组织损伤分级。预后不良危险因素的确认对于临床医师确定翻修手术方案具有指导作用。

Abstract:

BACKGROUND: Reversion total hip arthroplasty for inflammatory pseudotumor is little reported.

OBJECTIVE: To investigate the prognosis of the reversion total hip arthroplasty for inflammatory pseudotumor and the related factors.
METHODS: Eighty-one patients failed metal-on-metal hip arthroplasty were recruited, the medical history, baseline data and information of primary arthroplasty were collected, and all preoperative examinations were completed prior to reversion. The postoperative joint function was evaluated by Hospital for Special Surgery score, and the morphology of prosthesis was observed by radiology. Additionally, the serum levels of cobalt and chromium ions were detected, as well as the incidence of complications and the related factors were analyzed.
RESULTS AND CONCLUSION: (1) There was a significant increase in Hospital for Special Surgery hip score and significant decrease in serum levels of cobalt and chromium ions after reversion (P=0.000). (2) The postoperative incidence of complications and secondary reversion rate was 16% and 6%, respectively. (3) Preoperative prosthesis loosening (P=0.012), tissue cirrhosis revealed on MRI (P=0.000) and the injury degree of tissue (P=0.049) were found to be related to the incidence of complications. (4) Kaplan-Meier curve showed that the survival rate of prosthesis was 88% at 30 months postoperatively. (5) These results suggest that the prognosis of reversion total hip arthroplasty is poor, which is related to the preoperative aseptic loosening, tissue cirrhosis surrounding the joint and intraoperative tissue injury, thus providing guidance for surgeons to make an appropriate operative scheme.
