Mid-term results of ponseti method for the treatment of congenital idiopathic clubfoot - (A study of 67 clubfeet with mean five year follow-up)

Abstract

Abstract

Background: Long-term success reports by Dr. Ponseti with the Ponseti method in the treatment of congenital idiopathic clubfoot have led to a renewed interest in this method among pediatric orthopedists. The purpose of this study is to evaluate mid-term effectiveness of Ponseti method for the treatment of congenital idiopathic clubfoot.

Material and Methods: A total of 49 patients (67 clubfeet) were treated by Ponseti method by single orthopedic surgeon during the period of October 03 to July 07 and were studied prospectively up to July 10 (mean follow up period 5 years, minimum follow-up period of 3 years). Age at the initiation of the treatment, gender, bilaterality, severity of the initial clubfoot deformity measured by Pirani Severity Score System, total numbers of Ponseti casts before the tenotomy, details of tenotomy, compliance with brace and CTEV shoes were examined. Passive range of movements and look of club foot are evaluated with mean 5 years follow-up.

Results: We followed the functional Ponseti Scoring System and got good to excellent results in 44 patients - 89.79% (58 clubfeet - 86.56%) at mean five year of follow up. Parents of 32 patients (65.30%) accept the look of the clubfoot nearly normal and parents of 12 patients (24.49%) accept the look of clubfoot as normal. Of the 49 patients who responded to initial Ponseti casting, 14 patients - 28.57% (19 clubfeet - 28.35%) had relapse at varying age; out of which 9 patients - 64.29% (10 clubfeet - 52.63%) were corrected by Ponseti casting method, while 5 patients - 35.71% (9 clubfeet - 47.37%) were resistant to Ponseti method. Poor compliance with the Denis Browne splint was thought to be the main cause of failure in these patients.

Conclusion: Ponseti method is a safe and satisfactory treatment for congenital idiopathic clubfoot with mid- term effectiveness.
