Lateral antebrachial cutaneous neuropathies present as purely sensory lesions, manifesting as elbow pain or dysesthetic pain over the lateral forearm. Classically, entrapment of the lateral antebrachial cutaneous nerve has been documented at the lateral edge of the biceps tendon as it exits the deep fascia in the antecubital fossa. We report a case of lateral antebrachial cutaneous nerve traction neuritis, rather than entrapment, resulting from a rupture of the long head of the biceps. The biceps displaced the nerve laterally, resulting in sensory loss and severe allodynia. The patient's symptoms were relieved with proximal biceps tenodesis.
前臂外侧皮神经病变表现为单纯的感觉障碍，表现为肘部疼痛或前臂外侧感觉异常性疼痛。传统上，已有文献记载前臂外侧皮神经在肱二头肌肌腱穿出肘前窝深筋膜处的外侧边缘受压。我们报告一例因肱二头肌长头断裂导致的前臂外侧皮神经牵拉伤，而非受压。肱二头肌将神经向外侧移位，导致感觉丧失和严重的感觉异常性疼痛。患者的症状通过肱二头肌近端固定术得到缓解。
