Triple pelvic osteotomy (TPO) is one of the surgical procedures for use to try to reduce subsequent degenerative joint disease or modify the progress of hip dysplasia in young dogs. Joint force and pressure distribution were changed by this procedure. Therefore, the aim of this study was to find out whether the remodeling of proximal femur exists or not after TPO in dysplastic dogs. Ten femora from five young dysplastic mongrel dogs, treated unilaterally with TPO using 20° canine pelvic osteotomy plates, were used. One year after TPO, neck-proximal shaft angle, femoral head, neck, diaphyseal and mid-shaft diameters, total femoral, femoral neck axis, and intertrochanteric, femoral head offset lengths as well as the lengths from head center to lateral margin of greater trochanter and to proximal femoral axis were measured from the bone. The significant differences between treatment and control side were determined in Norberg angle, neck-proximal shaft angle, neck diameter, diaphyseal diameter, mid-shaft diameter, length from head center to proximal femoral axis and femoral head offset length. In conclusion, although small number of cases was used, it was determined that the aforementioned variables are affected by TPO. So, these variables may be supply additional information about the changes to the joint following TPO in dysplastic dogs.
三盆骨切开术（TPO）是一种用于尝试减少年轻犬后续退行性关节疾病或改变髋关节发育不良进展的手术程序。该手术改变了关节的受力和压力分布。因此，本研究旨在探讨 TPO 后发育不良犬的股骨近端是否存在重塑。使用 20°犬盆骨切开钢板对 5 只年轻发育不良杂种犬的单侧进行 TPO 治疗，选用其 10 根股骨。TPO 治疗 1 年后，从骨头上测量颈-近干角、股骨头、颈、骨干和中干直径、总股骨、股骨颈轴和转子间、股骨头偏移长度以及股骨头中心到大转子外侧缘和股骨近端轴的长度。确定了治疗侧与对照侧之间的 Norberg 角、颈-近干角、颈直径、骨干直径、中干直径、股骨头中心到股骨近端轴和股骨头偏移长度的显著差异。结论是，尽管使用的病例数量较少，但确定了上述变量受 TPO 的影响。因此，这些变量可能为 TPO 后发育不良犬关节变化提供额外信息。
