双赤道防脱位髋臼假体全髋关节置换的1年随访

Total hip arthroplasty with double mobility acetabular prosthesis:a 1-year follow up

背景:针对髋关节置换术后的脱位症状,双赤道防脱位髋臼假体应运而生,其在临床中的应用效果还需进行随访观察来验证。目的:观察应用双赤道防脱位髋臼假体进行全髋关节置换的早期临床疗效。方法:从2013年1月至2015年11月对30例患者运用双赤道防脱位髋臼假体行全髋关节置换,并对患者进行术后1年的临床随访观察,根据Harris评分、北京方案评分标准以及影像学评价方法了解患者的髋关节活动功能及松动情况。结果与结论:(1)30例患者均获得1年随访;(2)患者的平均Harris评分由术前的(39.7±3.87)分增加到术后1年随访时的(93.6±3.82)分,平均北京方案评分也由术前的(10.5±2.46)分增加到术后1年时的(17.3±1.87)分,差异有显著性意义(P<0.05);(3)假体置换前患者患髋均有中等程度以上的疼痛,术后28例患者髋关节轻度疼痛或无疼痛,2例患者中度疼痛;术后X射线检查显示髋关节稳定;(4)综上可知,应用双赤道防脱位髋臼假体进行全髋关节置换的短期随访效果令人满意,但中远期疗效还需进一步随访评价。

BACKGROUND： To solve the dislocation following hip arthroplasty, a double mobility acetabular prosthesis has beendeveloped, and its effect still needs to be confirmed through follow-up observation.OBJECTIVE： To explore the early clinical effectiveness of total hip replacement with double mobility acetabular prosthesis.METHODS： Thirty patients admitted from January 2013 to November 2015, were given total hip replacement with doublemobility acetabular prosthesis, and were then followed up for 1 year. The hip function and loosening were evaluated byHarris hip scores, Beijing program scaling and imaging examination.RESULTS AND CONCLUSION： （1） All patients were followed up for 1 year. （2） The mean Harris hip score wassignificantly increased from preoperatively （39.7±3.87） to postoperatively （93.6±3.82）, and the mean score of the Beijingprogram scaling was also significantly increased from （10.5±2.46） to （17.3±1.87） （both P 〈 0.05）. （3） All patients suffered frommoderate to severe pain before replacement, and 28 patients complainedmild or no pain and 2 patients with moderate painafter operation. X-ray showed a stable hip. （4） To conclude, the total hip arthroplasty with double mobility acetabularprosthesis achieves satisfactory short-term treatment outcomes, but its long-term effect needs to be observed further.
