Abstract：
UNASSIGNED: We present a rare case of ischemia caused by blunt trauma at the metacarpophalangeal joint, with no fracture or dislocation. This case resulted in digital arterial injury of the little finger with a pathological mechanism similar to that of hypothenar hammer syndrome (HHS).
UNASSIGNED: Pre-operative computed tomography (CT) revealed an occluded ulnar artery at the brachial artery bifurcation and occluded ulnar digital artery in the little finger. The blunt trauma to the radial digital artery of the little finger caused ischemia. Arterial anastomosis was performed microsurgically to preserve the little finger. Necrosis was successfully prevented. The condition of the finger improved gradually, with no restriction in the range of motion.
UNASSIGNED: When a patient presents with HHS-like symptoms and is unresponsive to conservative treatment, surgical treatment should be considered. We recommend using contrast-enhanced CT for evaluating the entire upper extremity, even for ischemia associated with blunt hand trauma, such as HHS.

摘要：
■我们介绍了一个罕见的由掌指关节钝性损伤引起的缺血病例，没有骨折或脱位。该病例导致小指指动脉损伤，其病理机制类似于小鱼际锤综合征（HHS）。
■术前计算机断层扫描（CT）显示肱动脉分叉处的尺动脉闭塞，小指中的尺动脉闭塞。小指桡动脉的钝性创伤引起缺血。显微手术进行动脉吻合以保留小指。成功预防了坏死。手指的状况逐渐改善，在运动范围内没有限制。
■当患者出现HHS样症状且对保守治疗无反应时，应考虑手术治疗。我们建议使用对比增强CT评估整个上肢，即使是与钝性手外伤相关的缺血，比如HHS。
