The pectoralis minor (PM) originates at the ribs medially and inserts at the medial border of the coracoid process. Pathologic shortening of the PM can be found in overhead athletes. A shortened PM is associated with anterior and internal rotation of the scapula, leading to scapular dyskinesis and anterior shoulder pain. Cases refractory to physical therapy and self-stretching exercises can be treated with isolated PM release. This procedure has been shown to be a safe and effective means of decreasing self-reported pain and activity limitations in patients with no other shoulder pathologies. We describe arthroscopic PM release in the beach-chair position in an athlete with recalcitrant shoulder pain and scapular dyskinesia.
胸小肌（PM）起于肋骨内侧，止于喙突内侧缘。在从事过头运动的运动员中可发现胸小肌的病理性缩短。胸小肌缩短与肩胛骨的前旋和内旋有关，导致肩胛骨运动障碍和肩部前侧疼痛。对物理治疗和自我伸展运动无效的病例可采用孤立性胸小肌松解术治疗。该手术已被证明是一种安全有效的方法，可减少无其他肩部病变患者的自我报告疼痛和活动受限。我们描述了在沙滩椅位对一名患有顽固性肩部疼痛和肩胛骨运动障碍的运动员进行关节镜下胸小肌松解术的情况。
