Painful Snapping Elbow in Patients With Congenital Radioulnar Synostosis: Report of Two Cases

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.
