title: Hypoplastic scaphoid--an unusual cause of carpal tunnel syndrome.
abstract: A case of median nerve compression within the carpal tunnel, secondary to hypoplasia of the carpal scaphoid and dysplasia of the distal radius, is described in a 15-year-old boy with Spondylo-epiphyseal dysplasia tarda. Hypoplastic carpal bones and a dysplastic distal radius may be a feature of Spondylo-epiphyseal dysplasias, but carpal tunnel syndrome has not been previously reported either in this condition or in association with hypoplasia of the scaphoid.
