Ulnar neuropathy at the wrist is an uncommon disease and pure ulnar sensory neuropathy at the wrist is even rarer. It is difficult to diagnose pure ulnar sensory neuropathy at the wrist by conventional methods. We report a case of pure ulnar sensory neuropathy at the hypothenar area. The lesion was localized between 3 cm and 5 cm distal to pisiform using orthodromic inching test of ulnar sensory nerve to stimulate at three points around the hypothenar area. Ultrasonographic examination confirmed compression of superficial sensory branch of the ulnar nerve. Further, surgical exploration reconfirmed compression of the ulnar nerve. This case report demonstrates the utility of orthodromic ulnar sensory inching test.
腕部尺神经病变是一种罕见疾病，而单纯性腕部尺神经感觉神经病变更为罕见。采用传统方法难以诊断单纯性腕部尺神经感觉神经病变。我们报告一例小鱼际区单纯性尺神经感觉神经病变病例。通过对尺神经感觉神经进行顺向移动试验，在小鱼际区周围三个点进行刺激，将病变定位在豌豆骨远侧3厘米至5厘米之间。超声检查证实尺神经浅感觉支受压。此外，手术探查再次证实尺神经受压。本病例报告展示了尺神经感觉顺向移动试验的作用。
