Poland’s syndrome concomitant with congenital proximaland distal radioulnar synostosis: A rare case report

Abstract

Radioulnar synostosis is a rare disease which causes supination andpronation restriction as a result of osseous or fibrous connectionsbetween the radius and ulna. Radioulnar synostosis includes bothcongenital and post-traumatic types. Post-traumatic radioulnarsynostosis can be seen in the proximal, middle, and distal part ofthe forearm, depending on the location of the trauma. Congenitalproximal radioulnar synostosis occurs as a result of a separationdefect between the radius and ulna in the embryonic period. Inthe presence of congenital proximal radioulnar synostosis, thepatient should be evaluated for accompanying syndromes andpossible developmental anomalies. In this report, we presenta rare case of both proximal and distal radioulnar synostosis.Hypoplasia of the right pectoral muscle mass, hypoplasticappearance of the right nipple, presence of proximal and distalradioulnar synostosis in the right forearm, and accompanyingsymbrachydactyly suggested Poland syndrome. To the best of ourknowledge this is the first case of congenital proximal and distalradioulnar synostosis with Poland syndrome.
