To report the short-term clinical outcome and complications in dogs that underwent surgical repair of femoral capital physeal or neck fractures via fluoroscopic-guided percutaneous pinning (FGPP).
Retrospective case series.
Client owned dogs (n = 11) with femoral capital physeal or neck fractures (n = 13).
Records (July 2018-July 2021) of dogs that underwent surgery for femoral capital physeal or neck fracture repair with FGPP from two hospitals were reviewed. Data collected included signalment, age, weight, preoperative lameness severity, fracture factors (etiology, Salter-Harris classification, time from injury to surgery, radiographic displacement), surgical factors (surgery time, number/size of implants, reduction quality) and outcome (follow-up examination findings, radiographic findings, complications).
Most fractures (11/13) occurred secondary to trauma. The median time from injury to surgery was 5.5 days. There was mild radiographic displacement preoperatively in 10/13 fractures. Satisfactory fracture healing and limb function was achieved in 10/13 femurs. Complications occurred in 5/11 cases and included intra-articular implants, implant failure/nonunion, implant migration (2), and malunion. Of these five complications, two resolved with implant removal, and a salvage procedure was recommended in the remaining cases. Of the three cases requiring salvage procedures, two originally presented with radiographic evidence of fracture chronicity.
FGPP can be used to successfully treat femoral head and neck fractures with appropriate case selection and precise surgical technique.
报告经荧光透视引导经皮穿刺（FGPP）治疗犬股骨近端干骺端或颈骨折的短期临床结果和并发症。
回顾性病例系列研究。
有股骨近端干骺端或颈骨折（n=13）的患犬（n=11）。
回顾了 2018 年 7 月至 2021 年 7 月期间，在两家医院接受 FGPP 治疗股骨近端干骺端或颈骨折的犬的手术记录。收集的数据包括品种、年龄、体重、术前跛行严重程度、骨折因素（病因、Salter-Harris 分类、受伤至手术时间、放射学移位）、手术因素（手术时间、植入物数量/大小、复位质量）和结果（随访检查结果、放射学结果、并发症）。
大多数骨折（11/13）继发于创伤。从受伤到手术的中位时间为 5.5 天。10/13 处骨折术前存在轻度放射学移位。13 根股骨中有 10 根骨折愈合和肢体功能良好。11 例中有 5 例发生并发症，包括关节内植入物、植入物失败/不愈合、植入物迁移（2 例）和畸形愈合。这 5 例并发症中有 2 例通过移除植入物得到解决，其余病例建议进行挽救性手术。在需要进行挽救性手术的 3 例中，有 2 例最初表现出骨折慢性的放射学证据。
FGPP 可用于治疗合适病例选择和精确手术技术的股骨头颈骨折，成功率较高。
