The aim of this study was to assess the kinetic and radiographic outcome of unilateral double pelvic osteotomy (DPO) using a temporospatial pressure walkway, preoperative and postoperative radiographs.
Retrospective case series of six dogs that underwent unilateral DPO for canine hip dysplasia. The untreated limb was unfit for DPO due to radiographic evidence of osteoarthritis and was therefore managed non-surgically. Preoperative and postoperative radiographs and kinetic data were compared between untreated and DPO-treated hips using a Wilcoxon signed-rank test.
There was no significant difference in British Veterinary Association Hip Dysplasia Scheme (BVA-HD) scores between untreated and DPO-treated hips preoperatively (-value = 0.09) and postoperatively (-value = 0.06). The median postoperative GAIT4 Dog Lameness Score was lower in untreated hips than DPO-treated hips but was not statistically different (-value = 0.18).
All dogs in this case series achieved a total pressure index and GAIT4 Dog Lameness Score on the DPO-treated hip comparable to normal limbs. All untreated hips in this series had increased BVA-HD scores at follow-up, whereas all DPO-treated hips had reduced BVA-HD scores. This difference was not significant and warrants further studies. We conclude total pressure index may be preserved in hips treated with unilateral DPO, while the contralateral hip is managed non-surgically.
本研究旨在通过时空压力步态仪评估单侧双骨盆截骨术（DPO）的动力学和影像学结果，包括术前和术后的影像学检查。
对 6 只因犬髋关节发育不良而行单侧 DPO 的犬进行回顾性病例系列研究。由于未治疗侧存在骨关节炎的影像学证据，不适合进行 DPO，因此采用非手术方法进行治疗。采用 Wilcoxon 符号秩检验比较未治疗侧和 DPO 治疗侧的术前和术后影像学和动力学数据。
术前（-值=0.09）和术后（-值=0.06），未治疗侧和 DPO 治疗侧的英国兽医协会髋关节发育不良评分（BVA-HD）均无显著差异。未治疗侧的术后步态 4 犬跛行评分（GAIT4 Dog Lameness Score）中位数低于 DPO 治疗侧，但无统计学差异（-值=0.18）。
本病例系列中的所有犬在 DPO 治疗的髋关节上均获得了与正常肢体相当的总压力指数和步态 4 犬跛行评分。本系列中所有未治疗的髋关节在随访时 BVA-HD 评分均增加，而所有 DPO 治疗的髋关节 BVA-HD 评分均降低。这种差异无统计学意义，需要进一步研究。我们得出结论，单侧 DPO 治疗的髋关节总压力指数可能得到保留，而对侧髋关节采用非手术方法治疗。
