摘要 目的：为尺神经卡压综合征的治疗提供解剖学基础。方法：解剖观察32个成人肘关节标本，测量肘管弓状韧带的长、宽和肘管中段的平均深度以及尺神经及其血供情况。结果：①肘管弓状韧带长为(13.3±3.6) mm，宽为(8.4±1.9) mm,肘管中段的平均深度为(4.8±1.3) mm；②尺神经在肘管内的横径为(4.5±1.1) mm；③肘部尺神经血供主要为尺侧上副动脉。结论：肘关节屈曲时肘管解剖形态的变化是产生尺神经卡压综合征的解剖基础，尺神经前移术是治疗尺神经卡压综合征的有效方法。

    Abstract Objective:To provide anatomic basis for treatment of cubital tunnel syndrome.Methods:32 elbows of adult cadavers were dissected.The length and width of the arcuate ligament,the depth of the cubital tunnel,the ulnar nerve and its vascular supply were measured.Results:①The length and width of the arcuate ligament were(13.3±3.6) mm and(8.4±1.9) mm.The depth of the cubital tunnel was(4.8±1.3)mm.②The diameter of the ulnar nerve was(4.5±1.1) mm.③The superior ulnar collateral artery was major arteries to supply the ulnar nerve at the elbow region. Conclusion: The morphologic change of the cubital tunnel was the anatomical pathogeny of the cubital tunnel syndrome.It is a effective method that transposition of the ulnar nerve in the elbow region to the cubital tunnel syndrome. ......
