The dorsal sensory branch of the ulnar nerve has been found to have the appropriate size and sufficient length for use as a digital nerve graft. This donor nerve was utilised fifteen times in twelve patients for the bridging of defects in thirteen digital nerves of the fingers. After an average follow-up of 23.2 months, only one patient failed to achieve any two point discrimination in the area supplied by the involved digital nerve. The other eleven patients had an average two point discrimination of 9.5 mm with a range of 5 to 18 mm. Painful neuroma formation or loss of hand function related to the use of the dorsal sensory branch of the ulnar nerve as a donor for digital nerve grafts was not encountered.
已发现尺神经背侧感觉支的大小合适且长度足够，可用于指神经移植。该供体神经在12例患者中使用了15次，用于桥接手指13条指神经的缺损。平均随访23.2个月后，只有1例患者在所涉及指神经支配区域未能实现两点辨别觉。其他11例患者的平均两点辨别觉为9.5毫米，范围为5至18毫米。未遇到与使用尺神经背侧感觉支作为指神经移植供体相关的疼痛性神经瘤形成或手部功能丧失的情况。
