title: Painful snapping elbow in patients with congenital radioulnar synostosis: report of two cases.
abstract: Two patients with congenital radioulnar synostosis presented with painful snapping on elbow motion in one case and locking of the elbow joint in the other. Elbow arthroscopy revealed the presence of tight fibrous tissue trapping the radial head. Arthroscopic removal of this tight fibrous tissue resulted in painless joint motion without recurrence of snapping or locking.
