摘要
目的：为临床尺管综合征和尺神经卡压、尺神经损伤的诊治提供解剖学依据。方法：在３０只成人手标本上解剖并观察了尺管的结构、尺神经的分支与走行。结果：依据尺神经在腕部和手掌的行程，将其分为豆钩管段、小鱼际段、掌中段、终末段。结论：尺神经深支在尺管内与豌豆骨、钩骨钩、豆钩韧带的关系密切。临床上骨折、韧带断裂、外伤都有可能引起神经损伤，产生尺神经卡压，出现尺管综合征。
Objective: To provide morphological basis for clinical diagnosis and treatment in ulnar nerve extrusion and ulnar tunnel syndrome.Methods: An anatomic study was performed in 30 cadaver hand specimens of the adults;the branches,the coursing and structure of the ulnar tunnel were observed.Results: According to the course of the ulnar nerve in ulnar tunnel,it is divided into the pisihamate part,the hypothenar segment part,the deep palmar segment part and the terminal part.Conclusions: The profound ulnar nerve in ulnar tunnel could be damaged in fracturing of pisiform bone and hamalus of hamate bone clinically, so the ulnar nerve oppression and ulnar tunnel sydrome might be developed.
