[Sprains of the wrist: current data and therapeutic orientations].

Despite the high incidence of wrist trauma, severe sprains with disruption of the ligaments are actually rare, apart from lesions of the scapholunate joint line. However, the diagnosis of severity should now be established, if not as an emergency, at least soon after the trauma, as deterioration of carpal instability always leads top osteoarthritis after a variable interval of time. When a ligament lesion is suspected, initial pain-free immobilisation, plain and dynamic x-rays followed by at least arthrography of CT arthrography, should be performed. After describing scapholunate sprain, the commonest form, the other varieties are reviewed: pyramidolunate, midcarpal, scaphotrapezoid, radiocarpal and finally inferior radioulnar sprains.
