Diagnosis and treatment of injury to the second and third carpometacarpal joints

We describe the diagnosis, treatment, and follow-up of a group of 13 patients with hand pain traced to pathologic conditions of the second or third carpometacarpal joints. Missed diagnosis was universal. With suspicion raised by history of injury or repeated stress and point tenderness on examination, diagnosis was confirmed by complete pain relief after injection of 1% lidocaine locally. In management of patients with occult pain in the hand, attention should be directed to the second or third carpometacarpal joints. Arthrodesis with use of an inverted triangular graft from the base of the metacarpal provides predictable and lasting relief.
