Neglected pediatric Monteggia fracture dislocation with persistent posterior interosseous nerve palsy: a case report

This is a rare case report of persistent PIN palsy following a case of neglected Monteggia fracture dislocation in a 7-year-old boy. The patient had presented with prominence around the elbow and inability to abduct the thumb, extend the thumb at interphalangeal joint, and inability to extend the fingers at the metacarpophalangeal joints. The index procedure of ulnar osteotomy and closed reduction of radial head did not yield satisfactory results; subsequently, patient underwent a second surgery for open reduction of radial and exploration of the PIN with simultaneous sural nerve grafting. To the best of our knowledge, this is the first case from India describing the use of sural nerve as a cable graft for neglected Monteggia fracture dislocation with nerve palsy.
