Description

Post-traumatic radioulnar synostosis (PRUS) is a rare but debilitating complication of forearm fractures, characterized by osseous fusion between the radius and ulna. We report a case of PRUS that developed 17 years after surgical fixation of a forearm fracture. Surgical excision of the synostosis led to excellent functional recovery. This case highlights the long-term risk of heterotopic ossification after forearm trauma and underscores the importance of meticulous surgical technique and early mobilization.
