[Dislocation of peroneal tendons].

From 1973 to 1985, 23 patients with a total of 25 peroneal tendon luxations were operated on. All luxations were successfully treated, although 1 patient had a recurrent dislocation and had to be operated on twice. At follow-up an average of 8.4 years later, 18 patients with 20 luxations were free of symptoms. In 3 patients there was a minimal loss in the range of movement in the ankle joint; in 1 the sensitivity of the skin distal to the incision was diminished and in 1 friction was found in the tendon sheath. The possibility of diagnosing these injuries precisely by tenography of the peroneal tendons and a tangential X-ray of the retromalleolar sulcus is pointed out. All fresh luxations were adequately treated by suturing the retinaculum; in some cases the sutures were secured with an additional screw. In patients with chronic luxation the procedure of Kelly can be recommended.
