Abstract:
The carpometacarpal boss is a bone prominence involving the carpometacarpal joints of the index and long fingers. In 1931 Fiolle described a bone lesion located the dorsum of his right wrist. He initially believed this to be primarily a carpal lesion and then called it a carpe bossu (carpal boss). The cause of the lesion has been thought to be the result either of a childhood fracture, or of an occupational strain or of periostitis secondary to the pull of the extensor carpi radialis brevis tendon insertion. A congenital predisposition, os styloideum, has also been suggested. We experienced three patients possessing a total of five lesions which showed that repeated mechanical stress in four and os styloideum in one were implicated in the etiology of this deformity.
