Although sites of ulnar nerve compression or disruption are generally apparent in a detailed physical examination, ulnar nerve involvement that is confined to the dorsal sensory branch of the ulnar nerve is unusual. Three patients presented with pain over the dorsal ulnar aspect of the hand associated with a cystic mass on the ulnar border of the wrist and hand. Stretching of the dorsal cutaneous branch from an underlying ganglion or proliferative synovium was present in all three of the patients.
尽管在详细的体格检查中，尺神经受压或中断的部位通常很明显，但仅累及尺神经背侧感觉支的情况并不常见。三名患者表现为手部尺侧背侧疼痛，伴有手腕和手部尺侧边界的囊性肿块。所有三名患者均存在来自潜在神经节或增生性滑膜的尺神经背侧皮支的牵拉。
