The metatarsus adductus is a common foot deformity.
With this deviation in position, children walk with their feet turned inwards. There is an adducted position of the forefoot in relation to the rear foot. In most cases, it is a posture-related deformity which can be corrected passively, resulting in a favourable prognosis.
Treatment is not necessary because in 90% of cases, the postural deviation recovers spontaneously before the age of four.
A distinction is made between the 'flexible' form (metatarsus adductus) and the 'rigid' (metatarsus varus), passive form that cannot be completely redressed. The latter requires correction by means of plaster redress and subsequent treatment with a night splint.
