Ulnar DimeliaIs it a true duplication of the ulna?From the Department of Orthopaedics, Greenwich District Hospital, London, UK Correspondence: J. Chinegwundoh, 19 Kenneth Court, 173 Kennington Road, London SE11 6SS, UK. Ulnar dimelia (mirror hand) is a rare congenital disorder, characterized by duplication of the ulna, absence of the radius and polydactyly. Approximately 60 cases have been reported worldwide. We present a new case, with its own distinguishing features. These features illustrate that the aetiology of ulnar dimelia is probably failure of differentiation of a part of the ray rather than its pure duplication.
