Abstract
1 . The indications, technique and results of supra-malleolar wedge osteotomy of the tibia in the management of valgus or varus deformity of the ankle in children with myelomeningocele are described.
2. This operation should not be performed until as much correction as possible has been obtained by soft-tissue release and muscle balance has been restored by tendon transfer.
3. In sixteen feet satisfactory correction was obtained and maintained in fourteen, one of which had required revision for over-correction.
4. A closing-wedge osteotomy is recommended ; the two failures occurred after opening-wedge osteotomies.
5. In the fourteen feet with satisfactory correction the complications were negligible, deformity has not recurred and epiphysial growth has been well sustained.
