Abstract
Introduction: While acute posterior interosseous nerve (PIN) palsy is a recognized complication of Monteggia fractures, delayed or tardy PIN palsy due to persistent radial head dislocation is exceedingly uncommon.
Case report: We describe a case of tardy PIN palsy 29 years after an unreduced Monteggia fracture, Bado type I.
Conclusion: While rare, delayed PIN palsy can occur in patients with old, unreduced Monteggia fractures. This underscores the need for a thorough medical history to detect potential causes, as long-standing injuries may eventually present symptoms. Treatment should target the underlying compression from the fracture dislocation while preserving the patient's adapted function.
