Abstract
Purpose: Currently, the optimal time to initiate treatment among preterm infants with clubfoot is unknown. The aim of this study was to describe treatment outcomes up to 1 year post-correction following Ponseti management in infants who were born preterm but treated at term age.
Methods: A retrospective chart audit was conducted at a major pediatric hospital on preterm infants with clubfoot who commenced Ponseti management at term age (≥37 weeks of gestation). Data are expressed as mean values (±standard deviation) or 95% confidence intervals (95% CIs).
Results: Twenty-six participants (40 feet) born at 32.6/40 (±3.1) weeks of gestation were identified. Thirteen (50%) were male, 14 (54%) presented bilaterally, and 7 (27%) presented with syndromic clubfoot. Ponseti management was initiated at 41.4/40 (±2.8) weeks gestation. Baseline Pirani scores were 5.2 (95%CI: 4.8–5.6) in the idiopathic group and 5.7 (95%CI: 5.0–6.4) in the syndromic group. The number of casts to correction was 5.9 (95% CI: 5.1–6.6) for those with idiopathic clubfoot and 6.1 (95%CI: 5.0–7.3) for those with syndromic clubfoot. Achilles tenotomies were required in 13 (21 feet) with idiopathic clubfoot and five (7 feet) with syndromic clubfoot. Recurrence occurred in four infants (5 feet): 4 feet required further casting and bracing, and 1 foot required additional surgery.
Conclusion: Ponseti management at term age in preterm-born infants yields comparable 1-year outcomes to term-born infants. Further research is required to determine whether outcomes beyond 1 year of age align with growth and development demonstrated by term-born infants who are managed with the Ponseti method.
Level of evidence: Level IV.
