Carpal coalition is a well-documented skeletal anomaly. Of the various coalitions that have been described, the lunate-triquetrum is the most prevalent. The pisiform-hamate coalition, originally reported in the West African Yoruba tribe, is rare. All 6 cases were incidental findings in asymptomatic patients. Recent reports document patients with tenderness on palpation of the coalition and ulnar neuropathy. Here we report the case of an asymptomatic pisiform-hamate coalition and review the literature.
