Abstract
Purpose
The rate of club foot recurrence following Ponseti treatment has been reported in the literature as between 14 and 58%. Recurrence is defined as any child who has been treated and is in need of recasting, surgery or bracing. True recurrence is defined as presentation 6 months after last treatment and incomplete treatment is defined as presentation within 6 months of last treatment. Currently no local data exists to determine the cause of recurrence in this unit. The aim of this study is to review all recurrences to improve the outcome of club foot management.
Methods
A retrospective audit of all club foot recurrences was performed at an academic hospital. The review included the location of initial treatment, initial treatment method and abduction brace compliance as factors contributing to the recurrence rate.
Results
Thirty seven (48%) patients attending the club foot clinic were recurrences – 68% were true recurrences and 32% were defined as incomplete treatments. The mean age at presentation of club foot recurrence was 25 months (Range 6–84 months). Seventy percent of recurrences were referred from outside healthcare facilities – all patients had serial manipulation and casting. The overall complete compliance for casting was 74%. Eighty percent of patients had a Tendo Achilles tenotomy at a mean age of 10.5 months (range 2–66 months) after initial plastering (mean 12.5 plasters). Post tenotomy, 65% had abduction bracing for a mean duration of 4.5 months and 35% had no bracing. No patient continued bracing until the recommended age of four years.
Conclusion
Despite the challenges of compliance to casting the overwhelming identified problem is compliance with abduction bracing. The challenge is to improve bracing protocol and ensure compliance in this critical part in the treatment of club foot.
