Objective The aim of this study was to categorize the presentation, management, complications and long-term outcome of canine acetabular fractures, and to determine the factors affecting outcome.

Materials and Methods Case records and imaging for dogs with acetabular fractures were reviewed with long-term follow-up via canine brief pain inventory (CBPI) and owner questionnaires.

Results The majority of fractures were in the mid-third (36/52) and caudal-third (13/52) with few in the cranial-third of the acetabulum (3/52). Concurrent injuries were diagnosed in 47/49 dogs; 10/34 dogs had neurological deficits on presentation. Forty-seven fractures received treatment: 25/47 had direct surgical repair (DSR), 10/47 had salvage surgery (SS) and 12/47 had conservative management (CM). Fracture location significantly affected treatment group (p = 0.001). New neurological deficits were documented after DSR in 5/24 dogs and SS in 2/10 dogs. Short-term complications occurred after DSR in 10/18 dogs (five minor, five major) and CM in 1/8 dogs (major). Long-term complications occurred after DSR in 2/15 dogs (major) and CM in 2/7 dogs (catastrophic). Conservative management dogs had worse average owner-reported CBPI scores than DSR or SS dogs.

Clinical Significance Acetabular fractures predominate in the mid and caudal acetabulum, with high levels of concurrent injuries. Fracture location significantly influenced the treatment approach taken. Postoperative neurological deficits are common following SS and DSR.

目的 本研究的目的是对犬髋臼骨折的表现、处理、并发症和长期结果进行分类，并确定影响结果的因素。

材料和方法 通过犬类短暂疼痛量表 (CBPI) 和主人问卷调查对犬髋臼骨折的病例记录和成像进行了长期随访。

结果 大多数骨折发生在髋臼的中三分之一 (36/52) 和尾部三分之一 (13/52)，少数发生在髋臼的前三分之一 (3/52)。在 47/49 只狗中诊断出并发损伤；10/34 狗在演示时有神经缺陷。47 处骨折接受治疗：25/47 接受直接手术修复 (DSR)，10/47 接受挽救性手术 (SS)，12/47 接受保守治疗 (CM)。骨折位置显着影响治疗组（p  = 0.001）。5/24 只狗 DSR 和 2/10 只狗 SS 后记录了新的神经功能缺损。10/18 只狗（5 只轻微，5 只主要）和 1/8 只狗（主要）在 DSR 后出现短期并发症。2/15 犬（主要）和 2/7 犬（灾难性）CM 在 DSR 后发生长期并发症。与 DSR 或 SS 犬相比，保守管理犬的主人报告的 CBPI 平均得分更差。

临床意义 髋臼骨折主要发生在髋臼中部和尾部，并发损伤程度较高。骨折位置显着影响了所采取的治疗方法。SS 和 DSR 后常见的术后神经功能缺损。
