Carpal coalition: A review of current knowledge and report of a single institution's experience with asymptomatic intercarpal fusion.

Background: Carpal coalition is a relatively common, yet poorly recognized, anomaly that may present independently or in association with syndromic or metabolic disorders. While largely asymptomatic, symptoms may manifest secondary to biomechanical stress at the site of fusion. The purpose of this report is to describe 103 cases of carpal synostosis and provide a review of the etiology, classification, and clinical significance of intercarpal fusion.
