Isolated traumatic posterior dislocation of the radial head in an adult, a rare injury: New case report.

Isolated radial head dislocations are rare in adults with only 23 cases published in 45 years. The diagnosis may be easily missed on radiographs and a CT-scan is often required. If managed promptly patient can restore normal range of motion and elbow function. Authors report a new case of a 67-year-old female presenting a posttraumatic isolated posterior dislocation of the radial head. Treatment consisted of closed reduction followed by immobilization for four weeks in a plaster cast with the elbow flexed at 90°, followed by active mobilization and physiotherapy. At 18 months of follow-up, functional outcome is excellent with no differences between both sides.
