Research Progress on Leg Length Discrepancy after Total Hip Arthroplast

下肢不等长是全髋关节置换术后最常见的并发症之一。尽管下肢不等长的幅度是可变的，但一般 > 10 mm通常是不可接受的，因此应尽一切努力将其最小化。因此，了解下肢不等长的分类、发生率、测量方式、发生因素、影响、预防和治疗措施是必要的。本文就全髋关节置换术下肢不等长关于上述内容进行综述，希望可以帮助骨科医生更加了解和认识全髋关节置换术下肢不等长的研究进展，以期更好地防治下肢不等长，使患者获得良好的下肢功能与满意度。 Leg length discrepancy (LLD) is one of the most common complications following total hip arthroplasty (THA). Although the degree of LLD varies, a discrepancy exceeding 10 mm is generally considered unacceptable, and every effort should be made to minimize it. Therefore, it is essential to understand the classification, incidence, measurement methods, contributing factors, clinical impact, and preventive and corrective measures for LLD. This article provides a comprehensive review of LLD after THA, focusing on the aforementioned aspects. The aim is to enhance orthopedic surgeons’ understanding of current research advancements in post-THA LLD, thereby improving its prevention and management to achieve optimal lower limb function and patient satisfaction.
