[The humeroradial impingement].

Lateral pain of the elbow is frequently reported. Impingement of the humeroradial fold or a synovial fringe is a seldom evoked cause, sometimes ignored. Nonetheless, this etiology should be remembered in young adults performing sport activities and in heavy workers. Pain can be acute and inflammatory. Elective pain is usually elicited by the pressure on the humeroradial joint space, beneath the lateral epicondyle. Snapping, locking and restricted mobility can be observed. MRI-arthrogram is the best radiological examination to perform. Symptoms can be improved by conservative treatment but may warrant an arthroscopical resection.
