Legg-Calve-Perthes (LCP) disease can result in morphological deformities and associated adult hip arthritis. Thirty-five consecutive total hip arthroplasties (THA) were performed in 28 patients with a history of LCP using a non-cemented modular femoral component. There was one revision for late hematogenous infection and no evidence of prosthesis failure. Harris hip scores, on average, improved from 49.8 (26-73) to 93.9 (82-100) (P<0.05) after a minimum of 2 years follow-up (average, 8.2 years, range 2-14 years). Clinically, patients demonstrated diminished or no limping (94%, 33/35) and improved leg length equality post-operatively (100%, 35/35). This style of stem accommodated metaphyseal/diaphyseal size mismatch in 80% (28/35), allowed for abnormal anteversion in 71% (25/35), and resulted in radiographic improvements in trochanteric height (P<0.05), body weight lever arm (P<0.05), and leg length (P<0.05).
Legg-Calve-Perthes (LCP) 病可导致形态畸形和相关的成人髋关节关节炎。28 例 LCP 病史患者采用非骨水泥模块化股骨组件进行了 35 例全髋关节置换术 (THA)。有 1 例因晚期血源性感染而进行了翻修，无假体失败的证据。在至少 2 年的随访后 (平均 8.2 年，范围 2-14 年)，Harris 髋关节评分平均从 49.8(26-73)提高到 93.9(82-100)(P<0.05)。临床结果显示，94% (33/35)的患者术后步态改善或无跛行，下肢长度均等性得到改善 (100%，35/35)。这种类型的柄可适应 80% (28/35)的干骺端/骨干大小不匹配，允许 71% (25/35)的异常前倾角，并导致转子间高度 (P<0.05)、体重杠杆臂 (P<0.05)和下肢长度 (P<0.05)的影像学改善。
