Traumatic Posterior Dislocation of the Radial Head in an Adult : A Rare Case Report.

A 26 year old male reported with gross limitation of pronation and supination of right forearm 8 week after a vehicular accident. X-Ray of the elbow showed isolated radial head dislocation without any associated fracture. It was treated with radial head excision with almost full restoration of movements postoperatively. The case is presented because of rarity of this injury and the tendency to miss this rare injury especially in the presence of other distracting injuries. However its early diagnosis and proper management is required to prevent chronic pain in future due to ensuing osteoarthritic changes and the disability of pronation and supination.
