An anatomical study was performed on the ulnar nerve to determine whether branches are present in the region of the incision for open or endoscopic carpal tunnel release that may be transected or traumatized, resulting in painful neuromata or dysesthetic symptoms. Twenty-four cadaveric forearms were dissected under 3.5-loupe magnification. A palmar cutaneous branch of the ulnar nerve was found in 42% of the limbs. Branches of the nerve were found in the proximity of the incision for carpal tunnel release in 12.5%. The palmar cutaneous branch of the median nerve was present in 92% of the limbs, with 8% having a branch in proximity to the incision. These anatomical findings suggest that injury to the palmar cutaneous branch of the ulnar nerve may be responsible for the "painful scar" more often than the palmar cutaneous branch of the median nerve.
对尺神经进行了一项解剖学研究，以确定在开放式或内镜下腕管松解术的切口区域是否存在可能被横断或损伤的分支，从而导致疼痛性神经瘤或感觉异常症状。在3.5倍放大镜下解剖了24具尸体前臂。在42%的肢体中发现了尺神经的掌皮支。在12.5%的肢体中，在腕管松解术切口附近发现了神经分支。正中神经的掌皮支在92%的肢体中存在，8%的肢体在切口附近有分支。这些解剖学发现表明，尺神经掌皮支损伤比正中神经掌皮支损伤更常导致“疼痛性瘢痕”。
