Suprascapular neuropathy after an arthroscopic repair of a SLAP lesion is theoretically possible, but it has been rarely reported. We present a case of suprascapular nerve injury at the spinoglenoid notch as a complication of an improperly inserted suture anchor after repair of a type II SLAP lesion. The diagnosis was confirmed by the magnetic resonance imaging findings and an electrodiagnostic study, and direct compression of the nerve was visualized under repeat arthroscopy. An anatomic study of the superior glenoid shows that the available bone stock of the superior glenoid rim for the anchor insertion is found to decrease posteriorly. During the repair of a SLAP lesion, surgeons should consider the possibility of an iatrogenic injury to the suprascapular nerve by an improperly inserted suture anchor.
冈上肌神经损伤是关节镜下 SLAP 损伤修复术后一种理论上可能出现的并发症，但极为少见。我们报道了一例因 II 型 SLAP 损伤修复时锚钉植入不当导致的肩胛上神经在肩胛切迹处损伤的病例。该诊断通过磁共振成像（MRI）和电诊断研究得到证实，并在重复关节镜检查下观察到神经直接受压。对肩峰上解剖结构的研究表明，用于锚钉插入的肩峰上缘的可用骨量向后减少。在 SLAP 损伤修复过程中，外科医生应该考虑到锚钉植入不当导致医源性肩胛上神经损伤的可能性。
