Comparison of Radiological Outcome of Conventional vs Accelerated Ponseti Casting Technique for Treatment of Club Foot

This open-label randomized controlled trial will be conducted at the dedicated Ponseti clinic, Department of Orthopedic and Trauma, Khyber Teaching Hospital, Peshawar, Pakistan, over six months. A total of 158 club feet (105 infants) with idiopathic club foot aged \<6 months will be enrolled using non-probability consecutive sampling. After informed consent and baseline X-ray, participants are randomly allocated (sealed envelope, odd/even numbers from OpenEpi) to either standard once-weekly casting (every Monday) or accelerated twice-weekly casting (Monday and Friday). All other Ponseti protocol elements (manipulation, number of casts, tendo Achillis tenotomy when indicated, final cast for 3 weeks, and foot abduction orthosis) are identical. The primary outcome is lateral talocalcaneal angle (mean of dorsiflexion and plantar flexion views) ≥35° on standardized X-ray six weeks after bracing. Secondary outcomes are talocalcaneal index \>40 and tibio-calcaneal angle 60-90°. Adverse events (skin sores, swelling, cast issues) are recorded. Allocation concealment is blinded to investigator and parents; the outcome assessor (pediatric orthopaedic fellow) is blinded to group assignment. Data will be analyzed using SPSS v20 (intention-to-treat, independent t-test or Mann-Whitney U, adjusted odds ratios, p\<0.05 significant). Ethical approval will be obtained from Khyber Medical College, KMU, and ASRB. Treatment is free, but no financial compensation is provided.
