Congenital metatarsus adductus: clinical evaluation and treatment.

Congenital metatarsus adductus, a deformity at the tarsometatarsal joints in which the metatarsals are deviated internally in relation to transverse plane, predisposes to "pigeon-toed" gait. Treatment is aimed at achieving normally balanced foot by overcorrection at the deformity sites. The most common problem after treatment is pronation deformity, which can be avoided by carefully positioning the heel at the time of casting. The sooner conservative measures are instituted, the more easily and rapidly the deformity will be corrected. If conservative casting does not result in improvement, then soft tissue surgery is indicated.
