摘要:

肘管综合征患者常伴有尺神经分布部位感觉异常和手部肌肉萎缩。当肌力减退或保守治疗失败后,常采用神经前置方法修复治疗。实验通过对18具成人尸体上肢肘部的尺神经和血管进行测量,收集了为肘部尺神经供血的主要3根动脉尺侧上副动脉、尺侧下副动脉和尺侧返动脉后支的初始点血管外径、动脉起点和肱骨内上髁间的距离及伴随尺神经血管的长度的数据。进而通过模拟无张力条件下带血管蒂的尺神经前置修复治疗肘管综合征,直尺测量得出无张力条件下,带血管蒂的尺神经前置的最适当距离为1.8±0.6cm(1.1-2.5cm)。这为应用带血管蒂尺神经前置修复治疗肘管综合征神经损伤提供了最适距离长度参考值。

Abstract:

Cubital tunnel syndrome is often accompanied by paresthesia in ulnar nerve sites and hand muscle atrophy. When muscle weakness occurs, or after failure of more conservative treatments, anterior transposition is used. In the present study, the ulnar nerve and its blood vessels were examined in the elbows of 18 adult cadavers, and the external diameter of the nutrient vessels of the ulnar nerve at the point of origin, the distances between the origin of the vessels and the medial epicondyle of the humerus, and the length of the vessels accompanying the ulnar nerve in the superior ulnar collateral artery, the inferior ulnar collateral artery, and the posterior ulnar recurrent artery were measured. Anterior transposition of the vascularized ulnar nerve was performed to treat cubital tunnel syndrome. The most appropriate distance that the vascularized ulnar nerve can be moved to the subcutaneous tissue under tension-free conditions was 1.8 ± 0.6 cm (1.1–2.5 cm), which can be used as a reference value during the treatment of cubital tunnel syndrome with anterior transposition of the vascularized ulnar nerve.
