We have investigated the changes in the interposed capsule after a Chiari pelvic osteotomy, in an experimental study on dysplastic hips in 20 adolescent rabbits. Radiographic, macroscopic and microscopic observations were made up to 12 months after operation. The new acetabular roof had incorporated the interposed capsule and remodelled completely by six months. By 12 months there was a new, stable hip with continuity between the capsule and the original acetabular cartilage. Histologically, the capsule underwent metaplastic change to fibrocartilaginous tissue after six months, with some hyaline-like cartilage near the joint surface. These changes in the interposed capsule play an important role in the formation of a new joint after a Chiari pelvic osteotomy.
在一项针对20只青春期发育不良兔髋关节的实验研究中,我们调查了Chiari骨盆截骨术后置入关节囊的变化。术后12个月内进行了影像学、大体和显微镜观察。新的髋臼顶在6个月时已融合了置入的关节囊并完全重塑。到12个月时,形成了一个新的、稳定的髋关节,关节囊与原始髋臼软骨之间具有连续性。组织学上,6个月后关节囊发生化生,变为纤维软骨组织,关节面附近有一些类似透明软骨的结构。置入关节囊的这些变化在Chiari骨盆截骨术后新关节的形成中起重要作用。
