Mastisol to help casts stay on for infants with bilateral clubfoot

A Randomized Controlled Trial Comparing Outcomes and Complications Following Mastisol Application for Clubfoot Casting

Not applicable Interventional University of Wisconsin, Madison · NCT07154550

This trial tests whether applying Mastisol adhesive before casting helps infants with bilateral clubfoot keep their casts on, shorten treatment, and reduce complications during casting and up to five years afterward.

What this trial studies

Infants with bilateral clubfoot beginning Ponseti casting will have Mastisol applied to the skin prior to cast placement and will be followed through their casting course, typically 8–12 weeks. The study will record cast slippage, skin irritation or sores, development of complex clubfoot, length of treatment, recurrence, and any need for reconstructive surgery. Participants will receive standard Ponseti manipulations and casting with or without Mastisol and will be monitored clinically with follow-up extending up to five years. The goal is to determine whether improved cast adherence translates into faster or more durable correction and fewer complications.

Who should consider this trial

Good fit: Infants aged 0–12 weeks with bilateral clubfoot starting Ponseti casting whose parent or guardian can read and speak English and provide consent are ideal candidates.

Not a fit: Children with unilateral clubfoot, those who begin treatment after 12 weeks of age, or infants whose caregivers cannot provide informed consent in English would not be eligible and are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, Mastisol could reduce cast slippage and skin complications, shorten Ponseti casting duration, and lower the chance of clubfoot recurrence or need for reconstruction.

How similar studies have performed: Clinicians commonly use skin adhesives to improve cast adherence and small reports suggest reduced slippage, but robust long-term trial data specifically in clubfoot are limited.
