Abstract

Objectives The aim of this study was to determine the indications for, and complications of, plate removal surgery in horses that underwent internal fixation of limb fractures.

Study Design Medical records of horses presented to our hospital between 1990 and 2015 for the removal of plates after treatment of limb fractures were reviewed. Data collected at the time of initial presentation, including signalment, history, fracture features and treatment and information about the indications, timing and complications of implant removal were reviewed.

Results The most common bones involved were the ulna (n = 19) and third metacarpal and metatarsal bones (n = 14). A total of 63 plates were removed from 48 horses during 53 separate surgeries, and the complication rate was 6/48; six horses had complications related to implant removal, which included persistent infection (n = 1) and refracture (n = 5). Complications related to implant removal were associated with comminuted fractures (p = 0.002), age > 3 years (p = 0.016) and the presence of surgical site infection (p = 0.001).

Conclusion Plate removal after fracture healing is necessary in patients with implant-associated clinical signs. There is a strong relationship between the complication rate and the degree of comminution of the original fracture, increasing age and the presence of surgical site infection. The surgeon must be aware of these risk factors when planning plate removal.

四肢骨折内固定后钢板去除：48匹马适应症和并发症的回顾性研究。

摘要

目的 本研究的目的是确定接受四肢骨折内固定的马的钢板去除手术的适应症和并发症。

研究设计 回顾了 1990 年至 2015 年期间向我院提交的马在四肢骨折治疗后移除钢板的医疗记录。回顾了初次就诊时收集的数据，包括信号、病史、骨折特征和治疗以及有关植入物移除的适应症、时机和并发症的信息。

结果 最常见的骨骼是尺骨 ( n  = 19) 和第三掌骨和跖骨 ( n  = 14)。在 53 次单独的手术中，48 匹马共取出 63 块钢板，并发症发生率为 6/48；六匹马有与植入物移除相关的并发症，包括持续感染 ( n  = 1) 和再骨折 ( n  = 5)。与植入物移除相关的并发症与粉碎性骨折 ( p  = 0.002)、年龄 > 3 岁 ( p  = 0.016) 和手术部位感染的存在 ( p  = 0.001) 相关。

结论 对于有种植体相关临床症状的患者，骨折愈合后取出钢板是必要的。并发症发生率与原始骨折的粉碎程度、年龄增长和手术部位感染的存在密切相关。外科医生在计划移除钢板时必须意识到这些风险因素。
