Congenital proximal radioulnar synostosis—a case report

Congenital radioulnar synostosis is a rare anomaly of the forearm with restrictions of full movement of the affected limbs. It is often seen in early childhood when they present with functional impairments. A 10-year-old female with progressive difficulty with supination in both upper limbs seen in the OPD had bilateral forearm xray which showed bilateral proximal radioulnar synostosis. She was then scheduled for a corrective osteotomy. Diagnostic imaging helps in evaluation and treatment planning for congenital radioulnar synostosis as seen in this index case.
