以改良Watson-Jones入路微创行全髋关节置换与改良Gibson后侧入路全髋关节置换的近期疗效比较

背景：采用改良Watson-Jones入路的微创全髋关节置换近年来在国内外得到广泛的应用。 目的：比较改良Watson-Jones入路微创全髋关节置换与改良Gibson 后侧入路全髋关节置换的近期疗效。 方法：52例接受单侧髋关节置换患者，根据入院日期单双号，随机分为2组，实验组22例接受改良Watson-Jones入路微创人工全髋关节置换；对照组30例接受改良Gibson后侧入路人工全髋关节置换。 结果与结论：两组患者完整随访至置换后18个月49例，实验组失访1例，对照组失访2例。实验组手术时间多于对照组 (P < 0.05)，实验组切口长度、术中出血量、输血量、住院天数少于对照组(P < 0.05)。两组置换后出血量、Harris评分相比差异无显著性意义。两组患者均未发生感染、脱位、血管神经损伤、深静脉血栓形成等并发症。近期随访结果表明，改良Watson-Jones微创入路全髋关节置换创伤小，髋关节功能恢复好，能够有效预防并发症的发生。

Short-term clinical effects of modified Watson-Jones total hip arthroplasty versus modified Gibson approach

BACKGROUND: Recently, modified Watson-Jones total hip arthroplasty (THA) has been widely used in the world. OBJECTIVE: To compare short-term clinical effects between minimally invasive modified Watson-Jones THA and modified Gibson THA. METHODS: Twenty-two patients accepted modified Watson-Jones method and 30 patients underwent modified Gibson approach. RESULTS AND CONCLUSION: The follow-up time was 18 months in 49 cases, 1 case lost to follow-up in modified Watson-Jones group and 2 cases in modified Gibson group. The significant differences between two groups were observed in decreases of indicators such as length of incision, volume of blood loss perioperative period, volume of blood transfusion, days at hospital postoperatively and time of operation (P < 0.05). Volume of postoperative blood loss, position of prosthesis, and hip functional evaluation system (Harris) were not significantly different between two groups. Complications including infection, dislocation, neurovascular injury, deep vein embolism were not observed in all cases. The general results of modified Watson-Jones group are better than modified Gibson group according to the short term follow-up data. Minimal invasive method leads to decreases of complications, loss of blood and time at hospital, good results in hip function, and early exercise is available.
