本文模拟先天性髋脱位复位后股骨头受髋臼压迫的情形,将30只幼犬分为四组分别承受不同的压力,并于加压后1、2、3周进行骨内压测定、同位素骨扫描和组织学检查等.结果表明,随着股骨头与髋臼之间压力的增加,头坏死率增加,加压时间延长,坏死程度加重.

The etiology of avascular necrosis of the femoral head following the treatment for congenital dislocation of the hip(CDH)is believed to be secondary to mechanical forces between the femoral head and the acetabulum. A puppy experiment was designed to makea model of femoral head necrosis by increasing pressure between the femoral head and acetabulum. Intra-medullary pressure,isotopic scanning and histological changes of the femoral head were studied. The authors suppose the pathogenesis of the femoral head necrosis after the reduction of CDH. The prevention of the incidence of femoral head necrosis lies in avoidance of continuous compression between the femoral head and acetebulum.
