Congenital metatarsus varus may be thought of as a third of a club foot. There is a muscle imbalance; the tibial muscles pull the fore part of the foot into an adducted and supinated position. The deformity may not be noticed at birth, but it develops gradually in a manner similar to a deformity following poliomyelitis. The deformity can be corrected by a series of corrective casts. The suggestions for treatment are based on the personal treatment of 2,818 children with metatarsus varus deformity. A brief statistical review of these cases is presented. Until a method of prevention is found, the best possible procedure is to correct the deformities as they are presented.
