Three variations of Chiari's pelvic osteotomy were performed on 18 dysplastic hip joints in young, growing German shepherd dogs and rottweilers. The results of the operations and the reactions of the skeletal tissue were investigated radiologically and histologically after six and 12 months. By use of polyfluorochrome sequential labeling and microangiography, it was demonstrated that neither the formation of new bone nor the blood supply in the vicinity of the rim of the acetabulum (apophysis of the acetabular roof) was seriously impaired by the operation. Conversely, the operative technique was of decisive importance to the result of the operation. Only if the osteotomy was performed through the original acetabular rim, completely covering the femoral head, was the newly formed acetabular roof adequately biomechanically loaded, providing the conditions required for functionally adapted differentiation of skeletal tissue. Chiari's pelvic osteotomy can be performed on canine hips with good chances of success, provided one uses the proper operative technique. Apophyseal bone growth and the blood supply of the newly formed acetabular roof were apparently not disturbed by Chiari's operation.
对18只年轻、处于生长阶段的德国牧羊犬和罗威纳犬的发育不良髋关节实施了三种不同的Chiari骨盆截骨术。在术后6个月和12个月时，通过放射学和组织学方法对手术结果以及骨骼组织的反应进行了研究。通过使用多荧光色素顺序标记法和微血管造影术，结果表明手术并未严重损害髋臼边缘（髋臼顶骨突）附近新骨的形成或血液供应。相反，手术技术对手术结果起着决定性作用。只有当截骨术通过原始髋臼边缘进行，完全覆盖股骨头时，新形成的髋臼顶才能获得足够的生物力学负荷，为骨骼组织功能适应性分化提供所需条件。只要采用适当的手术技术，Chiari骨盆截骨术在犬类髋关节上实施成功的几率较大。Chiari手术显然并未干扰骨突的骨生长以及新形成髋臼顶的血液供应。
