To evaluate the acetabular ventroversion obtained with a modified triple pelvic osteotomy (2.5 PO) compared with that resulting from standard double pelvic osteo-tomy (DPO).
Ex vivo study.
Seven pelves obtained from skeletally mature dogs with a total body weight ranging from 26-41 kg were used.
Unilateral DPO technique and dorsal ischial mono-cortical osteotomy were performed on every right hemipelvis. Angular ventral rotation was measured by determining the relative orientation of two Kirschner wires placed in the ilial wing and in the dorsal acetabular rim.
The mean angle of ventroversion was 9.5 ± 5.2 degrees for the DPO group (range 2.1-18.1) and 10.9 ± 4.8 degrees for the 2.5 PO group (range 4.1-19.5). The mean difference between the 2.5 PO and DPO was 1.5 ± 0.6 degrees (range 0.5-2.1).
The 2.5 PO technique increased acetabular ventroversion versus DPO.
评估改良三联骨盆截骨术(2.5 PO)与标准双骨盆截骨术(DPO)所获得的髋臼前倾角。
体外研究。
使用7个来自骨骼成熟犬的骨盆,犬的总体重范围为26 - 41千克。
对每个右半骨盆进行单侧DPO技术和坐骨背侧单皮质截骨术。通过确定放置在髂骨翼和髋臼背侧缘的两根克氏针的相对方向来测量角向腹侧旋转。
DPO组的平均前倾角为9.5±5.2度(范围2.1 - 18.1度),2.5 PO组为10.9±4.8度(范围4.1 - 19.5度)。2.5 PO组与DPO组之间的平均差异为1.5±0.6度(范围0.5 - 2.1度)。
与DPO相比,2.5 PO技术增加了髋臼前倾角。
