Our objectives were: 1) to review the complications associated with stabilization of appendicular fractures in cats and small dogs using locking compression plates (LCP), and 2) to identify factors that could influence fixation construct stability.
Retrospective clinical study.
Medical and radiographic records of cats and small dogs with appendicular fractures treated with LCP were reviewed. Only cases with adequate follow-up to document clinical union and cases for which complications appeared before the clinical union were included. Complications were classified as implant-related complications or other complications. Cases with implant-related complications were compared to cases with non-implant-related complications for differences in signalment (species, age, body weight, multiple fractures), fracture location and type (fractured bone, fracture localization, closed or open fracture), reduction method (open reduction and internal fixation [ORIF] or minimally invasive plate osteosynthesis [MIPO]) and fixation evaluations (implant size, plate-bridging ratio, plate span ratio, working length, plate screw density, number of screws and cortices engaged per plate and per main fragment, ratio between screw and bone diameter at the narrowest aspect of the bone, and presence of ancillary fixation).
Seventy-five fractures from 63 cats (64 fractures) and 10 dogs (11 fractures) met the inclusion criteria. Eight humeral, 13 radio-ulnar, 26 femoral, and 28 tibio-fibular fractures were treated. Primary repair of the fracture was performed using 2.0 mm and 2.4 mm LCP in 22 and 53 fractures, respectively. Overall and implant-related complications were encountered in 13 and seven of 75 fractures, respectively. Fixation failure was not significantly associated with any aforementioned factor considered in this study, and in particular, there was no significant difference in the occurrence of fixation failure between fractures stabilized with two, or more than two, bicortical locking screws per main fragment.
2.0 mm and 2.4 mm LCP were used to manage appendicular fractures in cats and small dogs. The overall complication and fixation failure rate were comparable to those reported in previous studies in which various locking plate systems were used.
我们的目标是：1）回顾使用锁定加压接骨板（LCP）治疗猫和小型犬附肢骨折的相关并发症，以及2）确定可能影响固定结构稳定性的因素。
回顾性临床研究。
回顾了使用LCP治疗附肢骨折的猫和小型犬的医学及放射学记录。仅纳入有足够随访以记录临床愈合的病例以及在临床愈合前出现并发症的病例。并发症分为与植入物相关的并发症或其他并发症。将与植入物相关并发症的病例与非植入物相关并发症的病例在信号特征（物种、年龄、体重、多发骨折）、骨折部位和类型（骨折骨、骨折定位、闭合或开放性骨折）、复位方法（切开复位内固定[ORIF]或微创钢板接骨术[MIPO]）以及固定评估（植入物尺寸、钢板桥接率、钢板跨度率、工作长度、钢板螺钉密度、每块钢板和每个主要骨折块所使用的螺钉数量及皮质骨数量、在骨最窄处螺钉与骨直径的比例以及辅助固定的存在情况）方面的差异进行比较。
来自63只猫（64处骨折）和10只犬（11处骨折）的75处骨折符合纳入标准。治疗了8处肱骨骨折、13处尺桡骨骨折、26处股骨骨折和28处胫腓骨骨折。分别使用2.0 mm和2.4 mm的LCP对22处和53处骨折进行了骨折一期修复。75处骨折中分别有13处和7处出现了总体并发症和与植入物相关的并发症。固定失败与本研究中考虑的任何上述因素均无显著相关性，特别是，每个主要骨折块使用两颗或两颗以上双皮质锁定螺钉固定的骨折在固定失败发生率上没有显著差异。
使用直径2.0 mm和2.4 mm的LCP治疗猫和小型犬的附肢骨折。总体并发症和固定失败率与先前使用各种锁定钢板系统的研究报告结果相当。
