Objective: This study aimed to determine the effects of the number of total siblings, younger siblings, and complex clubfoot deformity on the brace compliance and recurrence in the management of children with clubfoot deformity using the Ponseti technique.

Methods: The data from 91 children, including 22 girls and 69 boys (total 130 idiopathic clubfeet), seen from 2016 to 2019 were prospectively collected and retrospectively reviewed. The deformity was unilateral in 52 (57.1%) children (32 right, 20 left) and bilateral in 39 (42.9%). The mean age at presentation was 2 (range, 1–30) weeks, and the mean follow-up was 21.5 (range, 12–36) months. All the clubfeet were treated according to the Ponseti method. After removing the cast, a foot abduction brace (Dennis Brown splint) was worn. A complex clubfoot deformity was identified in 12% (n=11) children. At the follow-up, the Pirani score, recurrence status, and brace compliance were recorded. Recurrent deformity was defined as any deformity recurrence requiring manipulation, recasting, or surgical treatment. Brace compliance was assessed per the parents’ report.

Results: The median number of children in a family was 3 (range, 1–12). A total of 53 (58.2%) parents had up to 3 children, and 38 (41.8%) parents had more than 3 children. Of the patients, 22 (24.2%) had younger siblings and 25 (26.4%) had a family history of clubfoot. A total of 58 feet (44.6%) in 40 children (43.9%) developed recurrence. Brace non-compliance was the main risk factor for recurrence, increasing the recurrence rate 32-fold compared with that of compliant parents (odds ratio [OR], 32.67, 95% confidence interval [CI], 10.02–106.49; p=0.001). The rate of non-compliance with brace use was 51.6% (n=47). Brace non-compliance was significantly associated with having a younger sibling (OR, 3.9; 95% CI, 1.36–11.2; p=0.011) and having a complex deformity (OR, 11.62; 95% CI, 1.42–95.1; p=0.022) but was not associated with the total number of children (OR, 1.61; 95% CI, 0.7–3.73; p=0.265).

Conclusion: Our study shows that having new siblings in the first years of the Ponseti treatment may increase the brace non-compliance by minimizing the attention paid to the children with clubfeet by their parents. Nonetheless, complex clubfoot deformity may promote brace compliance by increasing the parents’ interest during the treatment process.
