Triceps brachii injuries are uncommon, resulting from indirect or direct trauma generally associated with an eccentric contraction. The tendo-osseous junction is the most common location. An extensor lag and palpable gap are diagnostic of complete rupture. Diminished extension strength against resistance implies a partial triceps rupture. A radiograph must be obtained as triceps ruptures are associated with olecranon or radial head fractures. A lateral radiograph may reveal an avulsion or 'flake' fracture. Early surgical repair of complete tendon ruptures is recommended. Surgical results are generally excellent.
肱三头肌损伤并不常见，通常由与离心收缩相关的间接或直接创伤引起。肌腱-骨连接处是最常见的部位。伸肌滞后和可触及的间隙可诊断为完全断裂。抗阻力时伸展力量减弱提示肱三头肌部分断裂。由于肱三头肌断裂常伴有鹰嘴或桡骨头骨折，必须进行X线检查。侧位X线片可能显示撕脱或“片状”骨折。建议对完全性肌腱断裂进行早期手术修复。手术效果通常很好。
