Abstract
UNLABELLED
Subclavius posticus is a rare anomalous muscle that traverses from the costal cartilage of the first rib posterolaterally to the superior border of the scapula. We present an athlete who presented with incapacitating suprascapular nerve compression associated with a subclavius posticus diagnosed by MRI. Symptoms were relieved, and function was restored by decompression of the nerve and excision of the anomalous muscle. We present this case to bring awareness of the subclavius posticus as an anatomic variant and a potential additional source for compression in suprascapular neuropathy. We recommend high-resolution magnetic resonance imaging to evaluate cases of isolated suprascapular neuropathy.

摘要
未标注
后锁骨下肌是一种罕见的异常肌肉，从第一肋软骨后外侧横向延伸至肩胛骨上缘。我们报告一名运动员，其因后锁骨下肌导致肩胛上神经受压而出现功能障碍，通过磁共振成像（MRI）确诊。通过神经减压和切除异常肌肉，症状得到缓解，功能得以恢复。我们展示此病例是为了提高对后锁骨下肌作为一种解剖变异以及肩胛上神经病变潜在额外压迫源的认识。对于孤立性肩胛上神经病变的病例，我们建议采用高分辨率磁共振成像进行评估。
