  • Title: Avascular necrosis of the hamate treated with capitohamate and lunatohamate intercarpal fusion.
    Author: Mazis GA, Sakellariou VI, Kokkalis ZT.
    Journal: Orthopedics; 2012 Mar 07; 35(3):e444-7. PubMed ID: 22385462.
    Abstract:
    This article describes a case of a 58-year-old man with no significant underlying disease who had chronic pain due to osteonecrosis of the hamate. Following physical examination, imaging, and laboratory findings, he underwent surgical exploration via a limited dorsal approach. The hamate bone did not have a normal anatomical appearance or structure. It was marble-like in appearance, soft, friable, and lacking physiologic contour and bone strength. We removed the dorsal aspect of the hamate piecemeal. The articular surfaces of the adjacent carpal bones (capitate and lunate) were excised, and the lesion was packed with iliac autograft. Three months postoperatively, fusion of the remaining hamate and the adjacent capitate and lunate carpal bones was evident, and the patient reported mild wrist pain, moderate grip strength improvement, and mild improvement of wrist range of motion and stiffness. Currently, no standard treatment algorithm exists for patients with avascular necrosis of the hamate. However, delayed diagnosis of this clinical entity can be debilitating. A high index of clinical suspicion and an early course of treatment offers considerable benefits to patients with osteonecrosis of the hamate.
