Cubital tunnel syndrome is the second most common nerve entrapment neuropathy. When non-operative treatments fail, surgical intervention is indicated. Although there remains no consensus between simple decompression and anterior transposition, there is a growing recognition of improved clinical outcomes in the latter. Few details of ulnar nerve branches around the elbow are available however and their sacrifice may be necessary to facilitate anterior transposition. Therefore, ten cadaveric upper extremities were dissected to delineate the course and branching pattern of the ulnar nerve around the elbow joint; anterior transposition was also performed in the cadaveric specimens. Digital photographs of the dissection study were analyzed using the Image J package. Results show that distal ulnar nerve branches are distributed more laterally towards the olecranon and may potentially restrict transposition more than has been recognized; proximal branches may also overlap incision lines of such transposition procedures.
肘管综合征是第二常见的神经卡压性神经病。当非手术治疗失败时，需进行手术干预。尽管单纯减压与前移位术之间尚无共识，但越来越多的人认识到后者能改善临床疗效。然而，关于肘部周围尺神经分支的细节很少，为便于前移位术，可能需要牺牲这些分支。因此，解剖了10具尸体的上肢，以描绘肘关节周围尺神经的走行和分支模式；还在尸体标本上进行了前移位术。使用Image J软件包分析了解剖研究的数码照片。结果显示，尺神经远端分支更偏向鹰嘴外侧分布，可能比人们认识到的更限制移位；近端分支也可能与这种移位手术的切口线重叠。
