1. Thirty-three children with thirty-eight feet affected by a cavo-varus deformity and treated by calcaneal osteotomy with concomitant stripping of plantar muscles were reviewed two to ten years after operation.

2. Out of twenty-six patients who were over eleven years old at the time of the review, fourteen (with eighteen feet) did not need any further treatment. In three other patients the deformity had recurred to a slight degree but did not warrant tarsal reconstruction. In the remaining nine patients the recurrence was marked and necessitated tarsal reconstruction.

3. The combined procedure is of value when there is progressive deformity in children too young for tarsal reconstruction.
