Unilateral ischemia of hand digits is usually caused by thoracic outlet obstruction, arterial emboli from a cardiac source, or atherosclerosis. The case of a metal press worker with unilateral ischemia due to hypothenar hammer syndrome, a condition caused by the repetitive use of the hypothenar eminence as a hammer with resultant damage to the ulnar artery, is described. Most such patients present with unilateral ischemia in the ulnar artery distribution of the dominant hand. This patient had used both hands repeatedly to pound the edges of large steel plates and presented with nondominant-hand ischemia, but was found to have the syndrome bilaterally by angiography. The distinctive features of this syndrome, a preventable and treatable cause of digital ischemia, are emphasized.
手指单侧缺血通常由胸廓出口梗阻、心脏来源的动脉栓子或动脉粥样硬化引起。本文描述了一名金属冲压工人因小鱼际锤击综合征导致单侧缺血的病例，该综合征是由于反复用小鱼际隆起当作锤子使用，导致尺动脉受损所致。大多数此类患者表现为优势手尺动脉分布区域的单侧缺血。该患者双手反复用力敲击大钢板边缘，出现非优势手缺血，但血管造影显示双侧患有该综合征。本文强调了这种综合征的独特特征，它是一种可预防和可治疗的手指缺血病因。
