Coalizão Pancarpal – um achado raro

Abstract

Introduction: Carpal coalition is characterized by the anomalous union of two or more carpal bones. In osseous coalition, the carpal elements are united as a single osseous block, whereas, in nonosseous coalition, the affected carpal bones are united by either cartilage (synchondrosis), fibrous tissue (syndesmosis), or some combination. Case reports: Case 1: 56 year-old woman with pain and functional limitation in the right wrist for 4 months. It refers to rheumatoid arthritis for 25 years. Case 2: A 39- year-old man with pain in his right hand after trauma for five years. He refers to pain in the right hand before the trauma, but with marked worsening after the episode, limiting the movement of the joint. Discussion: Pancarpal coalition is the coalition of all or most of the carpal bones, when observed, usually occurs within the constellation of one syndrome, like Ellisevan Creveld syndrome, symphalangism, Steel syndrome,Holt-Oram syndrome, arthrogryposis multiplex congenital, otopalatodigital syndrome, and Apert syndrome. The carpal coalition may be possibly related to inflammatory arthropathies - rheumatoid arthritis, juvenile arthritis, psoriatic arthritis and Reiter Syndrome. Conclusion: We report two rare cases of pancarpal coalition of different etiologies documented by radiography and magnetic resonance imaging.
