A reasonably successful result attending the surgical management of calcaneus deformity depends upon: (1) accurate evaluation of the bony and muscular pathology; (2) the correction of overgrowth and disturbed relations in the depth of the os calcis and astragalus by a calcaneus type of foot stabilization; (3) the dressing of the foot in an overcorrected position after operation and after manipulation; (4) the best possible balancing of muscle pull where tendon transplantation is indicated; and (5) careful direction of early weight-bearing in properly built shoes.
