Hypothenar hammer syndrome (HHS) is a rare condition and is a term used to described an aneurysm or thrombosis of the ulnar artery. It is considered an occupational or recreational injury and usually results of repetitive trauma to the hypothenar region, where th unique anatomy after the artery leaves the Guyon canal, allows the arterial injury. Clinical manifestations are more often unilateral, involving the dominant hand. However, some authors report the existence of a previous arteriopathy, predisposing to the injury, after repetitive palmar trauma.The authors report the clinical case of a 60 year-old woman, with an ulnar aneurysm in the non dominant hand, without evident existence of repetitive trauma. The pathological examination of the artery revealed muscular hyperplasia, without the characteristics of muscular fibrodysplasia. The authors believe that this case, once again, demonstrates the existence of an autonomous and "previous" arteriopathy associated to the traumatic lesion.
小鱼际锤状指综合征（HHS）是一种罕见病症，是用于描述尺动脉动脉瘤或血栓形成的术语。它被认为是一种职业性或娱乐性损伤，通常是由于小鱼际区域反复受到创伤所致，动脉离开Guyon管后的独特解剖结构使得动脉易受损伤。临床表现多为单侧，累及优势手。然而，一些作者报告称，在反复的手掌创伤后，存在先前的动脉病变，这使得更容易受伤。作者报告了一例60岁女性的临床病例，其非优势手出现尺动脉瘤，且无明显反复创伤迹象。对动脉的病理检查显示有肌肉增生，但没有肌肉纤维发育异常的特征。作者认为，该病例再次证明了与创伤性病变相关的自主性“先前”动脉病变的存在。
