Abstract

Introduction: While the Ponseti method is the primary treatment for idiopathic clubfoot, its application in treating myelodysplastic clubfeet is less certain. Myelodysplastic clubfoot tends to be more severe and difficult to treat. Although the Ponseti method can initially correct these cases, there is conflicting evidence about recurrence rates and the need for additional treatment. This study aims to assess the effectiveness of the Ponseti method in treating myelodysplastic clubfeet compared with idiopathic clubfeet over a 20-year period. Methods: The study conducted a retrospective review of medical records from patients treated for clubfoot at a single institution (2002 to 2021), comparing children with myelodysplastic and idiopathic clubfoot. Included patients were under 18, initially treated with Ponseti-casting, and had a minimum 2-year follow-up. Data on demographics, treatment details, recurrence, and Patient-reported Outcomes Measurement Information System (PROMIS) scores were analyzed. Results: Forty-nine myelodysplastic and 512 idiopathic clubfeet in 366 patients met the inclusion criteria. Myelodysplastic cases had a median age of 5 months at presentation versus 2 months for idiopathic cases (P=0.002). Initial correction was achieved in 95% of idiopathic and 87.8% of myelodysplastic feet (P=0.185). Recurrence rates were higher in the myelodysplastic cohort, 65.3% versus 44.1% (P=0.005). Surgery was necessary to treat recurrence in 59.2% of myelodysplastic and 37.7% of idiopathic cases, P=0.003. Follow-up was 3.9±1.8 years for myelodysplastic and 3.3±1.5 years for idiopathic feet, P=0.030. Myelodysplastic feet had lower PROMIS mobility scores; 31.94±7.56 versus 49.21±8.64, P<0.001. Conclusions: To the best of our knowledge, we report the largest series of myelodysplastic clubfeet treated by Ponseti casting and the first to assess PROMIS data. Overall, the Ponseti method is as effective in obtaining initial correction in myelodysplastic clubfoot as it is in idiopathic clubfoot. However, myelodysplastic clubfeet has a higher risk of relapse and increased need for surgical interventions. Children with spina bifida may need closer follow-ups and more stringent adherence to bracing. Level of Evidence: Level III-therapeutic studies-investigating the results of treatment.
