Situation: A nurse on the pediatric ward cares for children with congenital and developmental conditions and supports their families. An infant with bilateral clubfoot has finished Ponseti casting and a percutaneous Achilles tenotomy. The parents ask how the foot abduction brace will be worn. What should the nurse answer?

After the weekly Ponseti casts and tenotomy, the foot abduction brace (shoes on a bar) is worn full time for about 3 months, then at night and during naps until about age 4. The correction relapses easily, and poor brace adherence is the main cause of relapse.

Bracing after Ponseti casting and tenotomy

The Ponseti method corrects clubfoot through serial manipulation, weekly casting, and usually a percutaneous Achilles tenotomy. However, the corrected foot retains a strong tendency to drift back into the equinovarus position. The foot abduction brace is not an optional accessory; it is the maintenance phase that protects the correction achieved during casting. Bracing adherence is the single most important factor in preventing relapse after initial correction. When parents ask how the brace will be worn, the nurse should explain both the schedule and the reason behind it.

The standard protocol after tenotomy and the final cast is to place the infant in a foot abduction brace consisting of shoes attached to a bar. During the first 3 months, the brace is worn full time, meaning 23 hours per day. This intensive initial phase maintains the stretch on the soft tissues while they remodel. After that, wear is reduced to nights and naps, typically continuing until about age 4. Key point! Stopping the brace too early, even if the foot looks straight, invites recurrence because the underlying soft tissue imbalance persists for years.

The rationale for this prolonged schedule is rooted in the pathophysiology of clubfoot. The deformity involves contracted medial and posterior soft tissues, and the remodeling of these tissues continues well beyond infancy. Relapse occurs most often when the brace is discontinued prematurely or worn inconsistently. Studies on bracing in clubfoot emphasize that the tendency to relapse remains a significant clinical problem, and the duration and consistency of brace wear directly influence long-term outcomes. The brace holds the foot in abduction and dorsiflexion, counteracting the deforming forces that would otherwise pull the heel into varus and the forefoot into adduction.

A common misconception is that once the child begins walking, the brace is no longer needed. This is incorrect. Walking does not maintain the correction; in fact, weight-bearing without brace support can allow gradual recurrence. Similarly, wearing the brace only at night for a few months is insufficient because the remodeling window is much longer. The correct answer is therefore full time for about 3 months, then nights and naps until about age 4.

Phase	Duration	Wear schedule	Purpose
Initial maintenance	About 3 months	Full time (about 23 hours/day)	Hold correction while soft tissues remodel
Extended maintenance	Until about age 4	Nights and naps	Prevent late relapse during growth

Watch out! The most common reason for clubfoot recurrence is not failed casting or surgery, but poor adherence to the bracing protocol. Nurses should anticipate that parents may find the brace bulky or worry about the child’s comfort. Providing clear anticipatory guidance about the schedule and reinforcing that the brace is temporary but essential helps families persist through the challenging early weeks. Brace designs continue to evolve, with newer dynamic bars aiming to improve comfort and tolerance, but the underlying principle of consistent, prolonged wear remains unchanged.
