The article deals with the results of the analysis of morphological changes in the perineural tissue of 54 hands (in 47 patients) which were treated by operation for compression of the ulnar nerve on the hand. The main variants of localization of compression of the ulnar nerve in Guyon's canal were revealed. The main trunk of the ulnar nerve is compressed at the level of the volar carpal ligament in most cases. Two or three levels of affection of the main trunk of the nerve or its branches are encountered in half of the cases. The causes of compression of the ulnar nerve on the hand are thickening of the volar ligament, facial bands, a firm aponeurotic border of the initial part of the hypothenar muscle, hygroma, pathological condition of the ulnar artery and veins, deformity of the bones after fracture of the radius or ulna, etc.
本文探讨了54只手（47例患者）尺神经手部受压手术治疗后神经周围组织形态学变化的分析结果。揭示了尺神经在Guyon管内受压的主要定位变异。大多数情况下，尺神经主干在掌侧腕韧带水平受压。半数病例中可发现神经主干或其分支有两个或三个受累水平。手部尺神经受压的原因包括掌侧韧带增厚、筋膜束带、小鱼际肌起始部坚韧的腱膜边界、腱鞘囊肿、尺动静脉的病理状况、桡骨或尺骨骨折后骨骼畸形等。
