SuperPATH入路全髋关节置换术的早期疗效

The early efficacy of total hip arthroplasty via SuperPATH approach

目的探讨SuperPATH入路行全髋关节置换术(THA)的早期疗效和术中处理策略。方法将70例行THA患者根据手术入路不同分为SuperPATH组(采用SuperPATH入路,35例)和常规组(采用常规后外侧入路,35例)。比较两组切口长度、术中出血量、手术时间、髋臼外展角和前倾角、下床活动时间、术后3个月Harris评分。结果患者均获得随访,时间6~13个月。SuperPATH组的切口长度、术中出血量、下床活动时间均小(少)于常规组(P<0.01);手术时间、髋臼外展角和前倾角、术后3个月Harris评分两组比较差异均无统计学意义(P>0.05)。结论 SuperPATH入路THA创伤小,术中出血量少,假体位置可,置换后功能锻炼早且好,但必须掌握好手术适应证并熟练手术操作。

Objective To investigate the early effect and intraoperative management strategy of total hip arthroplasty （THA） via supercapsalar percutaneously assisted total hip（SuperPATH） approach. Methods Seventy patients trea- ted with THA were divided to SuperPATH group（ SuperPATH approach） and conventional group（ conventional poste- rior lateral approach）with 35 cases in each group. These data were compared between two groups,including the inci- sion length, intraoperative blood loss, surgery time, cup inclination, cup anteversion, postoperative activity time, postop- erative 3-month Harris scores. Results All patients were followed up for 6 - 13 months. SuperPATH group of inci- sion length was shorter than conventional group; and intraoperative blood loss, postoperative landing activity time were less than conventional group（ P 〈 O. 01 ）. There were no significant differences between the two groups in term of sur- gery time, cup inclination, cup anteversion, postoperative 3-month Harris scores （ P 〉 0. 05 ）. Conclusions THA via SuperPATH approach has less wound and less intraoperative blood loss, which does not affect proshesis position and do functional exercise early and well. However, surgeons must master the surgical indications and surgical tech- niques of THA via SuperPATH approach.
