[Osteochondrosis of the pediatric foot].

Osteochondrosis is a heterogeneous group of self-limiting conditions characterized by disturbance of enchondral ossification caused by a lack of circulation. Foot pain is a relatively common problem in children and adolescents and may be due to osteochondrosis. Osteochondrosis of the growing foot shows painful radiological alterations including increased density, fragmentation and irregularity of the epiphyses, physes and apophyses. Lacking etiologic and pathophysiologic information, ostoechondroses have been documented in almost every bone of the foot and therefore should be considered in the differential diagnosis when evaluating pediatric foot pain. The most common localizations of osteochondroses of the growing foot include the navicular as Kohler's syndrome, the metatarsal as Freiberg's infraction and calcaneal apophysitis as Sever's disease. Prognosis and final outcome vary considerably between the different localizations. Physicians should therefore be informed about the etiology, clinical presentation and treatment options for osteochondroses of the growing foot.
