title: Varus and internal rotational deformity of the ankle secondary to distal tibial physeal injury.
abstract: Nine children who sustained Lauge-Hansen's supination-inversion injury of distal tibial physeal injury with intact distal fibular physis, were followed until their maturity. The average varus deformity was 39 degrees (maximum, 80 degrees) with 23 degrees of internal rotational deformity. The longitudinal growth of the fibula was retarded compared with opposite normal leg. There was early closure of the medial distal tibial physis, gradual upward migration of medial malleolus, and eventually medial subluxation of the ankle; these resulted in gradual varus and internal rotational deformities of the injured ankle. It is thought that the resultant disabling deformity of ankle should be prevented by any means, though presently there are no available effective methods of treatment. It is suggested that the repeated corrective osteotomy should be carried out before epiphyseal deformity of the distal tibia and subluxation of the ankle joint develop.
