Isolated anterior dislocation of radial head in an adult with atypical presentation: a case report

We report an unusual case of isolated anterior radial head dislocation in an 18 year old male, who presented with maintained supination–pronation movements of forearm but restricted elbow flexion-extension. Closed reduction was attempted but failed. Hence, open reduction was performed. However, reduction was unstable due to rupture of annular ligament. Hence, repair of the annular ligament was performed and a radio-ulnar k-wire was passed to maintain reduction of proximal radio-ulnar joint, thus keeping the annular ligament stress-free and hence, facilitating its healing. At 12 months of follow up, patient had normal elbow function and complete range of motion.
