Given the proximity and shared structures of Guyon's canal and the carpal tunnel, compression of the ulnar nerve is a rarely observed but possible complication of carpal tunnel release. In this case report, a patient underwent previous carpal tunnel release and immediately experienced ipsilateral hand weakness in keeping with an ulnar nerve compression syndrome. Clinical, electrodiagnostic, and magnetic resonance imaging findings after carpal tunnel release demonstrated a compression or injury to the deep motor branch of the ulnar nerve not previously present. Subsequent release of Guyon's canal identified a separate compartment of the deep motor branch of the ulnar nerve within the ulnar leaflet of the transverse carpal ligament. After the release of the motor branch from this compartment, the patient experienced recovery from their neuropathic symptoms. This case report outlines the relevant anatomy and clinical data surrounding an anomalous compartment of the deep motor branch of the ulnar nerve.
由于尺神经管与腕管位置相近且结构相同，尺神经受压是一种罕见但可能发生的腕管松解术并发症。在本病例报告中，一名患者此前接受了腕管松解术，并随即出现与尺神经压迫综合征相符的同侧手部无力症状。腕管松解术后的临床、电诊断和磁共振成像结果显示，存在此前未出现的尺神经深运动支受压或损伤情况。随后对尺神经管进行松解，发现腕横韧带尺侧小叶内存在尺神经深运动支的一个独立间隙。从该间隙松解运动支后，患者的神经病变症状得到缓解。本病例报告概述了围绕尺神经深运动支异常间隙的相关解剖结构和临床数据。
