Lengthening osteotomy of the fibula to correct a widened mortice of the ankle after fracture.

The subtle diagnosis of widening of the mortice requires special radiographs which also make possible the recognition and extent of shortening of the fibula. With the help of a special compression/distraction device, a lengthening osteotomy can be carried out more easily then by conventional means. a reconstructive lengthening osteotomy of the fibula in cases of widening of the mortice is well worth while when there is absent or minimal osteoarthritic change, irrespective of the time from the original injury.
