Purpose:Once Ponseti correction of a clubfoot is achieved and 3-month full-time bracing treatment is completed, part-time bracing treatment for 12 hours at night for 2 to 4 years is considered necessary to maintain a successful outcome. This study objectively documents the amount of daily orthosis wear time in those who maintained correction at age 2 years and, in so doing, determines how well patients' caretakers comply with the prescribed brace program.Methods:Patients <3 months old with idiopathic clubfeet when Ponseti treatment was initiated, who successfully maintained correction at age 2 years without surgery and who had complete objective brace wear data, were included. The foot abduction orthoses had a temperature data logger embedded in a shoe. Six 3-month time intervals were monitored in every patient as follows: Full time: 0 to 3; night time: 4 to 6, 7 to 9, 10 to 12, 13 to 15, and 16 to 18 months. The families were not informed that hours of brace wear were being measured.Results:One hundred twenty-four patients with 187 clubfeet were included. During the 0-to 3-month interval, wear time averaged 19.8 hr/d. After this period of full-time use, the night-time brace wear decreased over each of the subsequent five intervals: 11.9, 9.6, 8.6, 7.9, and 7.7 hours. By the 18-month period of brace wear, 1 of 3 patients wore the orthoses less than 6 hours per day, and nearly 1 of 2 patients wore the orthoses less than 8 hours per day.Discussion:In patients evaluated at age 2 years whose clubfeet had successful nonsurgical treatment, night-time brace wear varied greatly and decreased over each 3-month period measured. By the second year of bracing treatment, nearly half of the patients wore them 8 hours or less.Level of Evidence:Level IV case series.
