An 8-year-old intact male German shorthaired pointer was presented for a left pelvic limb lameness. Examination revealed a plantigrade stance with flexed digits in the left pelvic limb, and swelling of the left common calcanean tendon distally. Magnetic resonance imaging revealed a partial rupture of the left common calcanean tendon, involving rupture to the tendons of the biceps femoris, gracilis, and semitendinosus muscles. Surgical repair was performed using a modified 3-loop pulley suture. Postoperatively, the tarsus was immobilized with external coaptation. Destabilization of the external coaptation occurred over 9 weeks followed by physical rehabilitation and complete return to function at 10 months post-operative. This case report illustrates the utility of MRI as a diagnostic tool for evaluation of tendon pathology. MRI provided exceptional detail of the tendons that comprise the common calcaneal tendon and the anatomical relationships to surrounding structures which facilitated appropriate surgical correction.

一名8岁完好无损的男性德国短毛指针因左盆骨limb行而出现。检查发现左骨盆肢体屈曲，左足common骨远端向远端肿胀。磁共振成像显示左总的钙跟腱部分断裂，包括股二头肌，gra肌和半腱肌的腱断裂。使用改良的三环滑轮缝合线进行手术修复。术后，将external骨固定在外部配合下。外部接合的不稳定在超过9周的时间内发生，然后进行了物理康复，并在术后10个月完全恢复了功能。该病例报告说明了MRI作为诊断肌腱病理的诊断工具的实用性。
