Abstract
Between 1997 and 2002, seven talipes equino varus deformities in six patients were treated using gradual distraction and correction with the Ilizarov external fixator. Three patients had poliomyelitis, four patients had neglected clubfeet and two patients had relapsed club-feet. The mean age of patients was 13.3 years (5 to 21) and the mean duration of fixator application was 3.25 months. When the plantigrade position was achieved the fixator was removed and a below-knee walking cast was applied. Four months after fixator removal, additional bony correction surgery (triple arthrodesis) was done in three patients. At the time of fixator removal, a plantigrade foot was achieved in all patients.
The mean follow-up time from surgery was 26 months. Pin-tract sepsis in two patients was treated effectively with oral antibiotics. Other complications included meta-tarsophalangeal subluxation from flexor tendon contractures in one foot. There have been no recurrences of deformities.
Compared to preoperative status, gait was subjectively improved in all patients. Correction of the deformity in the patients who had a triple arthrodesis of the foot was achieved with less bone loss than in patients who had undergone a primary triple arthrodesis. These results suggest that treatment with Ilizarov frames is effective in the management of neglected and relapsed clubfoot deformities.
