Abstract
Purpose To report on 4 cases of avascular necrosis of the metacarpal head.
Methods We retrospectively reviewed 4 patients who received a diagnosis of avascular necrosis of the metacarpal head and were treated from 2000 to 2016.
Results All patients were males with involvement of the dominant hand. Three patients had a history of trauma and/or fractures in another finger and one had a history of fracture in the same finger. The diagnosis was confirmed on regular x-rays and magnetic resonance imaging. Nonsurgical management was offered to all patients (rest, placement of an orthosis, and nonsteroidal anti-inflammatory drugs) for 3 to 6 months. Two patients responded well to nonsurgical management and improved in their symptoms. One patient refused surgical intervention and continued to have persistent pain. The other patient was treated with curettage and bone graft and had total resolution of pain symptoms with full active range of motion.
Conclusions A high index of suspicion is required to diagnose and treat avascular necrosis of the metacarpal head correctly. Treatment options are numerous and require further studies to investigate their effectiveness in the treatment of this rare disease.
