Lateral epicondylitis, also known as tennis elbow, is a restricting injury for active people that sometimes requires an injection of corticosteroid and local anesthetic for pain relief. The chief symptom is that activities that supinate or dorsiflex the wrist usually cause pain at the origin of the extensor muscle group (figure 1: not shown). This muscle group acts in extension of the wrist, hand, and digits, and in supination of the wrist. Medial to the lateral epicondyle are the radial nerve and the radial recurrent artery.
外侧上髁炎，也称为网球肘，是一种困扰活动人群的损伤，有时需要注射皮质类固醇和局部麻醉剂来缓解疼痛。主要症状是，手腕旋后或背屈的活动通常会在伸肌肌群起点处引起疼痛（图1：未显示）。该肌群作用于手腕、手部和手指的伸展以及手腕的旋后。外侧上髁内侧是桡神经和桡侧返动脉。
