title: [Calcaneonavicular coalition and its treatment].
abstract: The work deals with calcaneo-navicular coalition which occurs most frequently. The clinical picture is discussed of this congenital defect which is usually manifested by the peroneal spastic flatfoot in the period around 10th year of age and biomechanics of the foot with this anomalous coalition is dealt with. As for therapy the authors recommend surgical resection of the bony bridge between the calcaneum and the navicular with subsequent filling of the defect by a muscular flap of the short extensor of toes as recommended by Bentzon in 1928. Proceeding from their own material the authors evaluate the effect of this operation in 6 feet. In obsoleta symptomatic cases the authors recommend in case of arthrosis of the talo-navicular articulation desis of this joint, in case of arthrosis of the whole Chopart's joint the triple desis sub talo is the method chosen. With regard to the simplicity of the surgical operation conservative therapy is not recommended. However, it is essential to operate on in due time, and namely as early as at the age of about 11 years. The work points out the frequent wrong diagnosis of the painful flatfoot and the necessity is emphasized of performing an oblique dorsoplantar projection of the foot to reveal calcaneo-navicular coalition.
