Correction of ankle valgus deformity secondary to multiple hereditary osteochondral exostoses with Ilizarov.
The following case report highlights basic aspects of Multiple Hereditary Osteochondral Exostoses (MHOCE) and discusses the successful treatment of an adult with ankle pain secondary to growth arrest and foreshortening of the fibula. Two salient features include the age of the patient at presentation and the success of the procedure. Symptomatic valgus deformities of the ankle secondary to MHOCE are normally corrected during adolescence, prior to physeal closure. Reducing the ankle mortise by distally displacing the fibula and correcting rotational and angular ankle deformities with Ilizarov external fixation improved this patient's ankle function and relieved his pain.
