Minimally Invasive Total Hip Arthroplasty Using a Posterolateral Approach: Technique and Preliminary Result

近幾年來，隨著微創手術的發展，微創全人工髋關節置換手術也漸漸成為一種趨勢。贊成者認為，這種微創技術可以減少軟組識的傷害，而這儼然是一種優勢。相反地，反對者則顧慮到因為手術視野的減少所產生的危險性。所以目前來說，微創全人工髋關節置換手術是否適用仍存在著許多爭議。本文目的在於報告我們使用後外側置入方式施行微創全人工髋關節置換手術的經驗和早期成果。從2005年8月至2006年7月期間，連續79位患者接受了此項手術（共85例髖關節置換）。我們依據臨床及X光的各項結果來做評估。平均手術時問是55分，平均住院日是5.3日。術後三個月的髖關節功能量表平均是92.0分。唯一一例(l.18%)的併發症是術中非移位性骨折，其他則沒有脫臼、神經血管損傷及術後感染等問題發生。短期追蹤的結果顯示，我們的手術併發症機率低且術後恢復良好，我們認為此種手術方法是安全而有效的。

Minimally invasive total hip arthroplasty (THA) has become popular over the past few years. The advantages of this technique include reduced soft tissue damage. On the other hand, there are new risks related to reduced visualization. The widespread introduction of minimally invasive THA is still controversial. Here, we present our experiences and early results with a posterolateral approach to minimally invasive THA. Between August 2005 and July 2006, 85 hips from 79 consecutive patients were operated on using posterolateral minimally invasive THA. The outcomes were assessed on the basis of clinical and radiographic parameters. The mean operative time was 55 minutes. The mean length of hospital stay was 5.3 days. Average postoperative Harris hip score was 92.0 at 3 months postoperatively. Complications included only one (1.18%) intraoperative nondisplaced calcar split. There were no cases of dislocation, neurovascular injury or postoperative infection. Our study indicates an early result of low complication rate and good functional recovery following minimally invasive THA using a posterolateral approach. This minimally invasive THA technique provides short-term safety and efficacy.
