[Osteotomy of the calcaneus for pes cavus in childhood].

Osteotomy of the calcaneus (Dwyer procedure) was performed in 14 children (26 feet) aged between 5 and 15 years. On four occasions it was associated with an osteotomy of the first metatarsal and on three occasions with tarsectomy. The technique is described and the results are analysed. The authors conclude that the results were good in children under the age of 10 whilst the feet were still supple. In children over the age of 10, in whom the feet were more rigid, the gait was improved but the cavus deformity was not improved. The best age for operation is between 6 and 10 years.
