[Lateral ligament ruptures of the upper ankle joint in children].

This report about 44 cases of fibular ligament lesions compares the results of two series of 22 cases, one investigated from 1978 to 1981 and the other from 1981 to 1983. Introduction of a special holding device in 1981 has resulted in more objective diagnostics. To prevent false indications for surgery the displacement under stress need to be compared with the healthy ankle. If there is 8 degrees difference an operation is indicated in children. Following the example of adult traumatology the introduction of a longitudinal epifibular incision and new techniques employed in ligament surgery have clearly improved the results of treatment.
