摘　　要：目的：探讨骨间后神经卡压综合征的临床和神经电生理特点。方法：回顾性分析2006年2月至2010年2月临床疑诊骨间后神经卡压综合征患者的资料，结合神经电生理检查确诊共23例，分析其临床和神经电生理诊断特点。结果：所有患者虽然临床发病过程、病情轻重有所不同，但23例肌电图都有异常：重点检查食指固有伸肌、伸指总肌及尺侧伸腕肌基本均有自发电位出现。18例（78％）运动传导反应异常；运动传导远端潜伏期、波幅、传导速度异常分别是16例（70％）、17例（74％）和12例（52％）；桡神经浅支感觉传导正常。结论：神经电生理检查是诊断骨间后神经卡压综合征的有效方法，对临床体征不明确、定位困难者，早期肌电图检查更为重要。Objective： To explore the clinical features and electromyographical diagnosis for posterior interosseous nerves（PIN） compressive syndrome（PINCS）. Methods： To analyze the clinical features, combined with electrophysiology to make a definite diagnosis of PINCS. The clinical data of the cases suspected of with PINCS from Feburary 2006 to Feburary 2010 were retrospectively analyzed. Twenty-three patients with PINCS were analyzed and compared. Results： Each of the patients with different onset process or patient＇s condition from each other showed abnormal electromyogram by focal points checking with extensor indicis propnus, extensor digitorum communis and extensor digili ulnaris. Fibrillation potential and positive sharp waves were found in all the cases. Eighteen cases （78%） showed abnormal motor conduction reaction including abnormol distal latencies （DML） in 16 cases（70%） ,abnormal reaction volatility in 17 cases（74%） ,abnormal motor nerve conduction velocities in 12 cases（52 % ）. The sensory conduction of superficial radial nerves was in normal state. Conclusions： Electrophysiology diagnosis is an effective method for definite diagnosis of PINCS. It is particularly important with electromyography to check on the beginning stage of PINCS which does not show obvious clinical features or difficult location of the disease.
