Major avulsion of the triceps tendon insertion was diagnosed in a 7-year-old domestic shorthair cat 3 weeks after developing sudden severe weightbearing lameness of the left thoracic limb. Diagnosis was confirmed with orthopaedic, radiographic and ultrasonographic examinations. The absence of adequate bone stock prevented the use of conventional techniques for tendon reinsertion. Instead, the tendon was reattached using an ultra-high molecular weight polyethylene (UHMWPE) ExtraTape prosthesis. It was stitched into the triceps tendon and superficial fascia, then passed through a bone tunnel drilled in the olecranon and secured with a preassembled cortical button. No external coaptation was used. Although the cat experienced temporary mild lameness, pain-free and satisfactory use of the left thoracic limb was observed 4 weeks postoperatively. By 12 weeks, the cat's gait had returned to normal, with no gap between the tendon and the olecranon. The cat resumed normal gait and range of motion 8 months postoperatively.
Triceps tendon disruption is difficult to manage. Conventional repair techniques consist of suturing the tendon ends and prolonged immobilisation with an external fixator, which may cause postoperative complications. This option is particularly difficult to implement in cats, which represents a challenge in postoperative management. The successful outcome obtained here suggests that surgical repair using the ExtraTape prosthesis, without external coaptation, may be a viable alternative for similar cases.
一只7岁的家养短毛猫在左前肢突然出现严重负重性跛行3周后，被诊断为肱三头肌腱止点严重撕脱。通过骨科、放射学和超声检查确诊。由于缺乏足够的骨量，无法使用传统技术进行肌腱重新附着。取而代之的是，使用超高分子量聚乙烯（UHMWPE）ExtraTape假体重新连接肌腱。将其缝合到肱三头肌腱和浅筋膜中，然后穿过在尺骨鹰嘴钻出的骨隧道，并用预组装的皮质纽扣固定。未使用外部固定。尽管这只猫经历了短暂的轻度跛行，但术后4周观察到左前肢无痛且使用情况良好。到12周时，猫的步态已恢复正常，肌腱与尺骨鹰嘴之间没有间隙。术后8个月，猫恢复了正常步态和活动范围。
肱三头肌腱断裂难以处理。传统的修复技术包括缝合肌腱末端并用外部固定器长期固定，这可能会导致术后并发症。这种方法在猫中尤其难以实施，这对术后管理构成了挑战。此处获得的成功结果表明，使用ExtraTape假体进行手术修复且不使用外部固定，可能是类似病例的一种可行替代方案。
