Treatment is usually with some combination of the
Ponseti method and French method. The Ponseti method involves a combination of
casting,
Achilles tendon release, and bracing. There are many commercial braces as well as a relatively inexpensive
open-source hardware brace that can be made with a
3D printer. The Ponseti method is widely used and highly effective under the age of two. The French method involves realignment, taping, and long-term home exercises and night splinting. Another technique, the Kite method, does not appear to be as effective. The Ponseti method is highly effective with short-term success rates of 90%. The most common reason for this is inadequate adherence to bracing, such as not wearing the brace properly, not keeping it on for the recommended length of time, or not using it every day. Children who do not follow proper bracing protocol have up to seven times higher recurrence rates than those who follow bracing protocol, as the muscles around the foot can pull it back into the abnormal position.
French method The French method is a conservative, non-operative method of clubfoot treatment that involves daily physical therapy for the first two months followed by thrice-weekly physical therapy for the next four months and continued home exercises following the conclusion of formal physical therapy. During each physical therapy session the feet are manipulated, stretched, then taped to maintain any gains made to the feet's range of motion. Exercises may focus on strengthening the
peroneal muscles, which is thought to contribute to long-term correction. After the two month mark, the frequency of physical therapy sessions can be weaned down to three times a week instead of daily, until the child reaches six months. After the conclusion of the physical therapy program, caregivers must continue performing exercises at home and splinting at night in order to maintain long-term correction. Compared to the Ponseti method which uses rigid casts and braces, the French method uses tape which allows for some motion in the feet. Despite its goal to avoid surgery, the success rate varies and surgery may still be necessary. The Ponseti method is generally preferred over the French method. Surgery was more common prior to the widespread acceptance of the Ponseti method. The extent of surgery depends on the severity of the deformity. Usually, surgery is done at 9 to 12 months of age and the goal is to correct all the components of the clubfoot deformity at the time of surgery, but, in some cases, surgery occurs over a period of time to completely correct the affected area. For feet with the typical components of deformity (cavus, forefoot adductus, hindfoot varus, and ankle equinus), the typical procedure is a Posteromedial Release (PMR) surgery. This is done through an incision across the medial side of the foot and ankle, that extends posteriorly, and sometimes around to the lateral side of the foot. In this procedure, it is typically necessary to release (cut) or lengthen the plantar fascia, several tendons, and joint capsules/ligaments. Typically, the important structures are exposed and then sequentially released until the foot can be brought to an appropriate plantigrade position. Specifically, it is important to bring the ankle to neutral, the heel into neutral, the midfoot aligned with the hindfoot (navicula aligned with the talus, and the cuboid aligned with the calcaneus). Once these joints can be aligned, thin wires are usually placed across these joints to hold them in the corrected position. These wires are temporary and left out through the skin for removal after 3–4 weeks. Once the joints are aligned, tendons (typically the Achilles, posterior tibialis, and flexor halluces longus) are repaired at an appropriate length. The incision (or incisions) are closed with dissolvable sutures. The foot is then casted in the corrected position for 6–8 weeks. It is common to do a cast change with anesthesia after 3–4 weeks, so that pins can be removed and a mold can be made to fabricate a custom AFO brace. The new cast is left in place until the AFO is available. When the cast is removed, the AFO is worn to prevent the foot from returning to the old position. Surgery leaves residual scar tissue and typically there is more stiffness and weakness than with nonsurgical treatment. As the foot grows, there is potential for asymmetric growth that can result in recurrence of foot deformity that can affect the forefoot, midfoot, or hindfoot. Many patients do fine, but some require orthotics or additional surgeries. Long-term studies of adults with post-surgical clubfeet, especially those needing multiple surgeries, show that they may not fare as well in the long term. Some people may require additional surgeries as they age, though there is some dispute as to the effectiveness of such surgeries, in light of the prevalence of scar tissue present from earlier surgeries.
Developing world Despite effective treatments, children in
LMICs face many barriers such as limited access to equipment (specifically casting materials and abduction braces), shortages of
healthcare professionals, and low education levels and socioeconomic status amongst caregivers and families. These factors make it difficult to detect and diagnose children with clubfoot, connect them to care, and train their caregivers to follow the proper treatment and return for follow-up visits. It is estimated that only 15% of those diagnosed with clubfoot receive treatment. ==Cultural references==
