INTRODUCTION
The purpose of this study was to determine whether surgical arthroscopic decompression or ultrasound-guided aspiration of a paralabral cyst would result in suprascapular nerve recovery from axonal regeneration based on electrodiagnostic testing.
METHODS
Nine patients with preoperative electromyography (EMG) evidence of suprascapular neuropathy due to paralabral cysts at the suprascapular or spinoglenoid notch were prospectively studied. Eight patients underwent arthroscopic surgical decompression, and 1 patient underwent ultrasound-guided aspiration. Postoperative EMG was performed in all patients to evaluate nerve regeneration.
RESULTS
Three (33%) patients had cysts at the suprascapular notch, whereas 6 (67%) patients had cysts at the spinoglenoid notch. All patients showed complete electrophysiological recovery after decompression.
DISCUSSION
Decompression of paralabral cysts at the suprascapular or spinoglenoid notch resulted in postoperative EMG evidence of nerve recovery. Long-term studies with a greater number of patients are required to elucidate time to recovery. Muscle Nerve 59:247-249, 2019.
简介
本研究旨在通过电诊断测试确定，对于肩胛上神经因肩胛盂上或肩胛上切迹处的滑囊囊肿受压导致的上肢神经病，手术关节镜下减压或超声引导下抽吸滑囊是否会导致轴突再生后的神经恢复。
方法
前瞻性研究了 9 例术前肌电图（EMG）显示肩胛上神经病变，病变与肩胛上或肩胛上切迹处滑囊囊肿有关的患者。8 例患者接受了关节镜手术减压，1 例患者接受了超声引导下抽吸。所有患者均进行术后 EMG 以评估神经再生情况。
结果
3（33%）例患者的滑囊囊肿位于肩胛上切迹，6（67%）例患者的滑囊囊肿位于肩胛上切迹。所有患者在减压后均出现完全的电生理恢复。
讨论
肩胛上或肩胛上切迹处滑囊囊肿减压后，EMG 显示神经恢复。需要进行更多患者的长期研究以阐明恢复时间。《肌肉神经》59：247-249，2019 年。
