Abstract
One hundred and ten cases of acute injury of the lateral ligament of the ankle were treated by immobilization using plaster cast for 4 weeks and functional brace for the following 2 or 3 months. Follow-up studies were carried out 3, 6, 12 and 18 months after this treatment. Instability was measured by a stress roentgenogram using a Telos-SE stress device. Comparison of the injured ankle to the opposite uninjured ankle showed a difference in talar tilt angles of less than 1°three months after treatment and no significant increase was seen at 18 months after injury, even with cases where the angle was over 15° right after injury.
