Part 1: Correction
Part 2: Maintaining Correction
and Preventing Relapse
Correction starts shortly after birth to allow for the most flexibility of tendons and ligaments. The practitioner will gently stretch the foot and set in a plaster cast every 5-7 days until it reaches a corrected position.
It usually takes 5-7 weekly casts, but can take more if the foot is atypical/complex. Once the foot has reached a corrected position, a "Achilles (heel cord) tenotomy" (also known as a Percutaneous Achilles Tenotomy) will take place, normally under local anesthesia. Not all babies will need this procedure, but almost 90% of cases will. This final cast will stay on for approximately 3 weeks, while the Achilles tendon heals.
After the final cast is removed, a baby is placed into an orthopaedic brace or "boots and bar" as it is referred to, which leads us to part 2 of The Ponseti Method of treatment!
Immediately after the final cast is removed, a baby will be fitted and placed into his or her "boots and bar" brace.
The brace consists of two AFO boots, connected by a bar. If treatment started at birth, typical protocol requires 23 hour wear the first 3 months, followed by a slow weaning to approximately 14 to 16 hours a day.
Current recommendation is that the brace is continued to be worn until the age of 4, however, many parents choose to continue with the brace until they size out of the AFOS. This is because relapse rates decrease each year a child wears the brace. The bulk of time in brace is at night to maintain correction while sleeping.
