Atrophy demarcating to musculus teres minor is seen in magnetic resonance imaging of the shoulder region in 3 to 5.5% of investigations. We describe seven patients with prolonged or recurrent pain of the shoulder region, who were diagnosed in ENMG with damage of the axillary nerve brand to m. teres minor. Probable causes included tear of the rotator cuff, luxation of the shoulder joint, nerve entrapment in the quadrilateral space, neuritis of the brachial plexus and iatrogenic damage associated with shoulder arthroscopy. This nerve damage cannot be proved clinically.
在肩部区域的磁共振成像检查中，3%至5.5%的病例可见小圆肌萎缩。我们描述了7例肩部区域长期或反复疼痛的患者，他们在肌电图检查中被诊断为腋神经支配小圆肌的分支受损。可能的病因包括肩袖撕裂、肩关节脱位、四边孔神经卡压、臂丛神经炎以及与肩关节镜检查相关的医源性损伤。这种神经损伤在临床上无法得到证实。
