A 38-year-old female nurse was seen initially with several years' history of recurring intermittent ulnar wrist pain and paresthesias. The pain was aggravated by specific tasks using her hands, such as typing. Splinting and two steroid injections into the area gave only temporary relief. Surgical exploration revealed a segment of the ulnar nerve composing approximately 15% of its volume to split from the main trunk of the ulnar nerve, perforate the flexor carpi ulnaris tendon, and then rejoin the ulnar nerve. The nerve branch was extracted from the flexor carpi ulnaris by dividing approximately 15% to 20% of the tendon, allowing the nerve to be removed from the perforation, and anatomically relocated. The patient resumed her normal activities and has had no further discomfort in her wrist.
一名38岁的女护士最初因数年反复出现的间歇性尺侧腕部疼痛和感觉异常前来就诊。使用双手的特定任务，如打字，会使疼痛加重。夹板固定和在该区域进行两次类固醇注射仅带来了暂时的缓解。手术探查发现尺神经的一段约占其体积的15%从尺神经主干分出，穿过尺侧腕屈肌腱，然后重新与尺神经相连。通过切断约15%至20%的肌腱，将神经分支从尺侧腕屈肌中取出，使神经能够从穿孔处移除并进行解剖学重新定位。患者恢复了正常活动，手腕也没有再出现不适。
