To report and evaluate the risk factors for complications following bi-oblique proximal ulnar osteotomy (PUO) in dogs.
82 client-owned dogs (93 limbs).
Clinical records of dogs treated with bi-oblique PUO over a 5-year period were reviewed. Postoperative radiographs were analyzed, and osteotomy location and angles were recorded; follow-up radiographs were reviewed to assess the degree of osteotomy healing. Complications were classified as minor, major, and catastrophic. Logistic regression analysis was performed to investigate possible associations between the predictor variables and occurrence of complications.
82 dogs (93 limbs) were included. Postoperative complications were documented in 39 limbs (13 major and 26 minor). The most common major complication was osteotomy nonunion (8 limbs), while the most common minor complication was delayed union (21 limbs). Statistical analysis revealed that lower body weight (P = .01) and older age (P = .04) were significantly associated with the development of postoperative complications.
In this study, lighter and older dogs were more likely to develop complications following bi-oblique proximal ulnar osteotomy. We did not identify an association between osteotomy angle and location on complication rate. Careful patient selection is therefore required to reduce the incidence of postoperative complications after bi-oblique PUO.
报告和评估犬双斜形尺骨近端截骨术（PUO）后并发症的危险因素。
82 只患犬（93 个肢体）。
回顾了 5 年内接受双斜形 PUO 治疗的犬的临床记录。分析了术后 X 线片，并记录了截骨位置和角度；复查 X 线片以评估截骨愈合程度。将并发症分为轻微、严重和灾难性。进行逻辑回归分析，以调查预测变量与并发症发生之间的可能关联。
纳入 82 只犬（93 个肢体）。39 个肢体（13 个严重，26 个轻微）记录了术后并发症。最常见的严重并发症是骨不连（8 个肢体），最常见的轻微并发症是延迟愈合（21 个肢体）。统计分析显示，体重较轻（P =.01）和年龄较大（P =.04）与术后并发症的发生显著相关。
在本研究中，体重较轻和年龄较大的犬在接受双斜形尺骨近端截骨术后更容易发生并发症。我们没有发现截骨角度和位置与并发症发生率之间的关联。因此，仔细选择患者对于降低双斜形 PUO 后术后并发症的发生率至关重要。
