The authors analyze the results of Chiari pelvic osteotomy in treatment of sequellae of hip osteochondritis with 11 cases of children 6 to 10 years old, operated and reviewed with an average follow up of 21 months. They used the operative procedure decided by Chiari, on orthopaedic table, followed by plaster cast immobilisation for 3 weeks. The Xray results are specially analyzed as the peroperative functional troubles were absent. This procedure is mainly effective on articular congruence with gain not only in lateral but also in anterior head-coverage. The secondary modelling appears to affect either the head and the acetabulum. But the medialization remains poor, which is explained by an analyze of the lower fragment operative displacement. Actually, this operative procedure may be used in late osteochondritis with a coxa magna and specially when a coxa vara or a short neck contra-indicate a femoral osteotomy.
作者分析了Chiari骨盆截骨术治疗6至10岁儿童髋部骨软骨炎后遗症的结果，对11例患儿进行了手术并进行随访，平均随访21个月。他们采用Chiari决定的手术方法，在骨科手术台上进行，术后用石膏固定3周。由于术前没有功能障碍，因此特别分析了X线结果。该手术主要对关节一致性有效，不仅增加了股骨头外侧覆盖，也增加了前侧覆盖。继发性塑形似乎影响股骨头和髋臼。但内移效果仍然不佳，通过分析下段手术移位可以解释这一点。实际上，该手术可用于晚期伴有大转子增大的骨软骨炎，特别是当髋内翻或短颈禁忌股骨截骨时。
