Abstract：
OBJECTIVE: Arthrodiastasis consists of the mobilisation of the hip while distracted by a hinged distractor. The aim of our study is to show the results of the treatment of late-onset Perthes disease with this technique in our institution.
METHODS: Ambispective review of all the cases that underwent this surgery in our Department of Paediatric Orthopaedics between 2010 and 2014 with the following inclusion criteria: patients over 8 years old, with minimal deformity, and poor prognosis. Mobility, pain, Trendelenburg sign, radiographic sphericity, and complications were assessed.
RESULTS: A total of 13 patients (9 male, 4 female) were included. The mean age was 11.93 years. Radiographic risk signs were present in 7 cases. The mean decrease in pain measured with a visual analogue scale (VAS) after the surgery was 3.83 points (P<.05). Cephalic sphericity was maintained in 11 cases during follow up (1.75 years). Complications were observed complications in 84.6% of the patients, with infection of the screw tract being the most frequent. All of them were easy to treat.
CONCLUSIONS: Arthrodiastasis is a minimally invasive technique, useful in the treatment of late onset Perthes disease. It improves clinical results and maintains cephalic shape when applied in early stages. However, it is not free of complications, which can involve as many as 8 out of 10 patients treated with the technique.

摘要：
目的：关节扩张包括髋关节的活动，同时由铰链式撑开器撑开。我们研究的目的是显示在我们机构中使用该技术治疗迟发性Perthes病的结果。
方法：对2010年至2014年在我们儿科骨科接受此手术的所有病例进行全面回顾，纳入标准如下：8岁以上的患者，最小的畸形，预后不良。机动性,疼痛,特伦德伦堡标志，射线照相球形度，并对并发症进行了评估。
结果：共有13例患者（9例男性，包括4名女性）。平均年龄为11.93岁。7例存在影像学危险体征。术后用视觉模拟评分法（VAS）测量的疼痛平均减轻为3.83分（P<0.05）。随访1,75年,11例保持头颅球形。并发症发生率为84.6%的患者,最常见的是螺钉道感染。他们都很容易治疗。
结论：关节炎是一种微创技术，可用于治疗迟发性Perthes病。它改善了临床结果，并在早期应用时保持头部形状。然而,它并非没有并发症，这可能涉及多达810名接受该技术治疗的患者。
