Abstract

OBJECTIVE

The aim of this study was to evaluate outcomes and complications of dogs that had pancarpal arthrodesis (PCA) using a titanium hybrid advanced locking plate system (ALPS) and stainless steel hybrid dynamic compression plate (HDCP).

STUDY DESIGN

Retrospective observational study.

METHODS

Medical records (2007-2020) were reviewed for cases that had PCA performed using ALPS or HDCP. Implant characteristics including metacarpal coverage (MCov), metacarpal width occupied by screw diameter percentage and carpal arthrodesis angle (CAA), complications and outcomes were recorded.

RESULTS

Pancarpal arthrodesis was performed with ALPS on 15 limbs from 12 dogs, and HDCP on 14 limbs from 11dogs. Median follow-up time was 1,157 days (range: 62-1,902 days) for ALPS group and 340 days (range: 43-1,465 days) for HDCP. Median MCov for ALPS group was 74% (range: 60-87.5%) compared with 56.5% (range: 49.7-91.3%) for HDCP ( = 0.001). There was no difference in CAA and metacarpal width to screw diameter percentage between ALPS and HDCP group. Major and minor complications and surgical site infection rates were not statistically different between the two groups. Plate fracture occurred in 2/15 ALPS PCA and screw loosening occurred in 4/14 HDCP PCA. Full function was achieved in 8/12 and 8/11 of ALPS and HDCP cases, respectively, which was not statistically different ( = 0.76).

CONCLUSION

The use of ALPS offers comparable performance to HDCP for PCA.

摘要

目的

本研究旨在评估使用钛混合先进锁定板系统（ALPS）和不锈钢混合动力加压板（HDCP）行全腕掌关节融合术（PCA）的犬只的治疗效果和并发症。

研究设计

回顾性观察性研究。

方法

回顾 2007 年至 2020 年期间使用 ALPS 或 HDCP 行 PCA 的病例。记录了包括掌骨干覆盖（MCov）、螺钉直径百分比占据掌骨干宽度和腕掌关节融合角（CAA）在内的植入物特征、并发症和治疗效果。

结果

12 只犬的 15 个肢体行 ALPS 全腕掌关节融合术，11 只犬的 14 个肢体行 HDCP 全腕掌关节融合术。ALPS 组的中位随访时间为 1157 天（范围：62-1902 天），HDCP 组为 340 天（范围：43-1465 天）。ALPS 组 MCov 的中位数为 74%（范围：60-87.5%），而 HDCP 组为 56.5%（范围：49.7-91.3%）（ = 0.001）。ALPS 和 HDCP 组的 CAA 和掌骨干宽度与螺钉直径百分比无差异。两组的主要和次要并发症以及手术部位感染率无统计学差异。2 例 ALPS PCA 发生钢板骨折，4 例 HDCP PCA 发生螺钉松动。ALPS 和 HDCP 组分别有 8/12 和 8/11 例完全恢复功能，无统计学差异（ = 0.76）。
