Wrist arthrodesis following ulnar bar excision in Fibrodysplasia ossificans progressiva

Fibrodysplasia ossificans progressiva is a rare disorder characterized by t he progressive development of heterotopic bone in the connective tissues of skeletal muscle, ligaments and tendons. Surgical trauma is one of the most potent stimuli for ossification and surgical treatment is generally consid ered to be contraindicated in this condition. We report a good functional r esult in a patient with severe hand disability secondary to an ulna-carpal bar in fibrodysplasia ossificans progressiva.
