Objective The purpose of this clinical communication is to report the management of common calcaneal tendon rupture in dogs using a transarticular calcaneo-tibial locking plate as a method of temporary immobilization of the tarsocrural joint to support primary repair of the common calcaneal tendon.

Study Design Dogs presented with partial or complete common calcaneal tendon rupture treated with primary tendon repair supported by the transarticular calcaneo-tibial locking plate technique from July 2016 to December 2019 were included. The tarsus was placed at a standing angle of 150 degrees and the pre-contoured Fixin locking ‘L’ or ‘T’ plate was medially applied with two locking screws inserted in the calcaneus and two screws inserted in the distal tibia. Tendon healing judgement was mostly based on clinical palpation and ultrasound examination was not performed in all the cases. Plates were removed in all dogs 6 weeks postoperatively.

Results All tendons healed and no complications at the level of the tenorrhaphy were noted in the postoperative period. All dogs returned to hunting activity with full function of the affected limb. No major complications requiring revision surgery were observed. Minor complications occurred in two cases; osteomyelitis and screw pull-out.

Conclusion The use of a transarticular calcaneo-tibial locking plate for temporary immobilization of the tarsocrural joint after surgical repair of common calcaneal tendon rupture appears to be an effective technique with comparable results to other reported techniques.

目的 本次临床交流的目的是报告使用经关节跟胫锁定钢板作为一种临时固定跗腿关节以支持跟骨总肌腱的初步修复的方法，对犬的跟骨跟腱断裂进行治疗。

研究设计 2016 年 7 月至 2019 年 12 月期间出现部分或完全的跟骨跟腱断裂，并通过经关节跟胫锁定钢板技术支持的初级肌腱修复治疗的犬被纳入研究。跗骨以 150 度的站立角放置，预成型的 Fixin 锁定“L”或“T”板在内侧应用，两颗锁定螺钉插入跟骨，两颗螺钉插入胫骨远端。肌腱愈合判断多基于临床触诊，并非所有病例均进行超声检查。术后 6 周在所有狗中取出板。

结果 术后肌腱全部愈合，无腱鞘水平并发症。所有的狗都以受影响的肢体的全部功能恢复了狩猎活动。没有观察到需要翻修手术的重大并发症。2例发生轻微并发症；骨髓炎和螺钉拔出。

结论 跟骨常见跟腱断裂手术修复后使用经关节跟胫锁定钢板临时固定跗脚关节似乎是一种有效的技术，其结果与其他报道的技术相当。
