Guest guest Posted November 9, 2004 Report Share Posted November 9, 2004 , I am no expert and you will probably get more answers from others but I believe the 70 degree rotation is necessary to prevent relapse. The same condition that causes clubfeet continues to cause it until the child is 3 or 4 and if the foot is not over corrected it can end up relapsing. I " think " the clubfoot should have a more outward rotation at her young age then the non clubfoot (someone correct me if I am wrong sense my daughter is bilateral). How long do you have to wait for the braces? Is she going into a DAFO? I hope the exercises work to help hold her over until your braces get there. I know for us exercises wouldn't have worked because Tori goes to daycare 9 hours a day and the daycare provider wouldn't have been to happy about doing exercises on her feet all the time. That might be why they usually recast until the braces are available. Hope you get some more answers.

Maybe it is different for kids or clubfooters or just different pain tolerances. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted November 9, 2004 Report Share Posted November 9, 2004 , Probably the best place to get the technical reasons as to why the FAB is the preferred method of post-correction bracing and why the AFO or DAFO is not as successful as the FAB in preventing relapses is to write to Dr. Ponseti and ask him for a technical explanation that you can share with your doctor....or ask your doctor to discuss it with Dr. Ponseti specifically. Here is a quote from Dr. P's website in the information for providers that is one of the common errors in the treatment of clubfoot: " Failure to use shoes or molded orthotics attached to a bar in external rotation for three months full-time and at night for two to four years. These splints are necessary to counter the tendency of the ligaments to tighten, causing relapses. The ankles and knees are free to move and the leg and thigh muscles gain strenghth. " It's brief, but essentially explains that the outward rotation is necessary to counter-act the ligaments pulling back in. The same is true for the Achilles tendon, which is why the shoes are mounted on the bar with a bend so that the toes are pointed upward, keeping the Achilles stretched. Don't worry about discussing your personal research with your doctor- you're not " telling " on him...it's your job as a parent to make decisions on your daughter's behalf- and you're doing a great job of educating yourself and understanding all that you can about this complicated medical condition so that you can discuss your daughter's treatment with your doctor and make decisions as a team- not just follow blindly along with his recommendations if you don't agree with them. If your doctor is a parent, you know that they would be doing the exact same thing for their own children! Please note that I've been told that just a few hours without a cast/brace during the initial stages of correction can allow some relapse to occur (may not be visible). So if you have a difficult time with Ava being in a brace when you do get it, you might want to consider having another cast re-applied to see if that might help the situation. Perhaps your doctor will suggest this anyway based on what he learns at the symposium!

Guest guest Posted November 9, 2004 Report Share Posted November 9, 2004 , We are sorry if we at this group sometimes seem a bit over zealous in tring to encourage you and/or other newer parents regarding the " real " Ponseti method. It is just that many of us have watched the experiences of 500-1,000 parents on the internet over the past 5 years. Many times, we see very similar experiences by many parents over the course of the years and are anxious to help. Please forgive us for occasionally being a little overly " helpful " . In his 1996 book, Dr. Ponseti talks about having a premature baby fully relapse in one week while they were waiting for smaller shoes. I think that the speed of relapsing was much faster than it would be in most children. Plus he indicated that premature babies in general relapse quicker. Regarding your specific question, I think that when Dr. Ponseti was developing his method in the late 1940s and 1950's, he didn't just start out doing 70 degrees because he wouldn't have known right from the beginning what worked better than other alternatives. I think that he initially used less overcorrection and lower amounts of time in the brace but saw higher rates of relapsing. In the first long term outcome study that Dr. Ponseti did in 1963, the rate of relapsing was almost half of the patients he treated. During the following years, he has adjusted the method to get less risk of relapsing. I beleive that over a 50 year period of implementing his method and seeing what worked better, Dr. Ponseti has indicated that using 70 degrees seems to work the best in getting a good outcome with less risk of relapsing. From 1991 to 2001, Dr. Ponseti's rate of relapsing for those complying with the prescribed use of the FAB/DBB was about 10%. The 70 degrees, bend of the bar and other aspects of the method have come from fine tuning the method over a 50 year period. Dr. Ponseti discusses this in an article on relapsing that he wrote in 2001. " In the first 20 years of my practice, relapses occurred in about half of the patients at ages ranging from ten months to five years, averaging two-and-one-half years. Usually, relapses were observed from two to four months after the splints were prematurely discarded at the families' own initiative, believing that the correction was stable. More recently, relapses have been less frequent because, for one thing, I have further overcorrected the deformity in the last plaster and to be certain that the calcaneus is fully abducted and its anterior joint surface is well under the head of the talus. Secondly, there has been greater awareness on the part of the Parents regarding the importance of maintaining the night splints after correction for three to four years. " Here is a full copy of that article written by Dr. Ponseti on the topic of the Treatment of Relapsing Clubfoot in the Ponseti method. It was a printed version of a Lecture delivered at the DC National Congress of the Italian Society of Pediatric Orthopaedics and Traumatology, in Rome, Italy at October 2001 and printed in a 2002 issue of the Iowa Orthopedic Journal. Iowa Orthopedic Journal: Volume 22, 55-56, 2002 RELAPSING CLUBFOOT: CAUSES, PREVENTION, AND TREATMENT, Ignacio V. Ponseti INTRODUCTION " Regardless of the mode of treatment, the clubfoot has a strong tendency to relapse. Stiff, severe clubfeet and small calf sizes are more prone to relapse than less severe feet. Clubfeet in children with very loose ligaments tend not to relapse. Relapses are rare after four years of age. " " Not all components of the clubfoot tend to relapse to the same degree. In most of our cases, forefoot correction is permanent without metatarsus adductus. The relapse of the cavus deformity is rare and usually mild. The most important relapses occur in the hindfoot, first in the equinus, and then in the heel varus. In some relapsed clubfeet, the heel varus is very severe, while in others it is mild. Rarely, the heel in equinus may go into valgus resulting in a calcaneovalgus deformity. This is a frequent occurrence in surgically treated clubfeet In our experience, most relapses develop gradually and may be difficult to recognize in the early stages. A relapse is detected when there is an appearance of a slight equinus and varus deformity of the heel, most often without increased adduction and cavus in the forefoot When walking, the child tends to put more weight on the outside of the sole of the foot. " CAUSES " It is wrongly assumed that relapses occur because the deformity has not been completely corrected. Actually, relapses are caused by the same pathology that initiated the deformity. Therefore, when we understand the pathogenesis of the clubfoot, the causes of the relapse will become clear. " " The clubfoot in otherwise normal children is a developmental anomaly originating after the third month of intrauterine life. It is induced by an unknown dysfunction in the posterior and medial aspects of the lower leg, ankle and foot. There is a slight decrease in size of the muscles, and an excess of colagen synthesis with retracting fibrosis in the medial and posterior tarsal ligaments, in the deep fascia, the tendo Achilles, and the posterior tibial tendon. These changes induce severe equinus, medial displacement of the navicular, heel varus and foot adduction. " " The period of dysfunction causing the deformity starting in the middle third of pregnancy lasts to the third or fourth year of life. In mild cases, it may start in late fetal life, and remain active for only a few months after birth. In all cases, the resulting fibrosis is most pronounced from. a few weeks preceding birth, to a few months after birth. This is the period when collagen accretion is greatest in tendons and ligaments of normal mammals and presumably also of man. The speed of growth of the foot decreases after the first year of life, diminishing greatly after five years. " " Relapses appear to be related to the intensity of collagen synthesis as the foot grows. Thus, relapses occur swiftly in premature infants and more slowly in older infants. Relapses are less common and less severe in mild club feet with little fibrosis and in children with loose ligaments. They occur because the factors inducing the deformity are still active. Relapses are rare after four years of age, regardless of whether the deformity is fully or partially corrected. " " The clubfoot is no different from other non-embryonic human deformities such as torticoris, scoliosis, or Dupuytren's contracture, in that it develops in normal individuals, and progresses for a limited time before becoming inactive. Torticollis usually develops within days after birth and increases for a few weeks. Idiopathic scoliosis starts in late childhood and increases throughout adolescence. Dupuytren's contracture develops at maturity and may be active for a few years. Clubfoot develops in the middle of pregnancy and is active during the first to fourth years of life. In torticollis, Dupuytren's contracture, and presumably in clubfoot, a localized temporary increase of collagen synthesis is a common pathologic feature. " " With our technique, most congenital clubfeet in infants are corrected within four to six weeks. However, splinting for several months or years is indispensable to help prevent relapses. Since the main corrective force of the varus and adduction of the clubfoot is abduction (external rotation) of the foot under the talus, a splint is needed to maintain the foot in the same degree of abduction as it was in the last plaster cast. This is best accomplished with the feet in well-fitted, open-toed high top shoes with a well-molded heel attached in 70 degrees external rotation to a bar of about the length between the baby's shoulders. Unless the feet are sprinted in firm external rotation, the pull of the retracting fibrosis in the ligaments of the medial aspect of the ankle and of the tibialis posterior and toe flexors is strong enough to cause a recurrence of the deformity in most feet. " " The splints are worn full time for two to three months, and thereafter at night and naps for two to four years. The splint should maintain the foot in 70 degrees of abduction to prevent relapse of the varus deformity of the heel of the adduction of the foot and the in-toeing. The ankle should be in dorsiflexion to prevent relapse of the equinus. This is accomplished by bending the splint with the convexity of the bar distally directed. A splint or strapping that cannot firmly maintain the foot in marked abduction without pronation is ineffectual. The added advantage of shoes attached to a bar, as opposed to a fixed splint, is that it allows motion of the feet, ankles and knees. Most babies feel uncomfortable for the first two to three days when trying to kick their legs alternatively. Parents can easily teach their babies to kick both legs simultaneously. The splints are then well accepted. " " In the first 20 years of my practice, relapses occurred in about half of the patients at ages ranging from ten months to five years, averaging two-and-one-half years. Usually, relapses were observed from two to four months after the splints were prematurely discarded at the families' own initiative, believing that the correction was stable. More recently, relapses have been less frequent because, for one thing, I have further overcorrected the deformity in the last plaster and to be certain that the calcaneus is fully abducted and its anterior joint surface is well under the head of the talus. Secondly, there has been greater awareness on the part of the Parents regarding the importance of maintaining the night splints after correction for three to four years. " " In recent years, I have treated 90 patients - 52 of them initially seen from birth to three months of age, and 38 from three Months to one year of age. Seventy Percent of the patients had plaster casts or physical therapy elsewhere. Forty patients had been previously indicated for surgery by the initial treating Physician. To my surprise, it was possible to successfully correct all these feet with manipulations, and four or five plaster casts, changed every five days. I performed percutaneous Achilles tenotomy in 84 percent of the patients. Eighty-eight percent of the patients were compliant with the use of the foot abduction splint. There were 14 relapses. The rate of relapse was seven percent in compliant patients, compared to 78 Percent in non-compliant patients. Relapses were unrelated to age at presentation or to the number of casts required for correction. " TREATMENT " In general the original correction may be recovered in four to six weeks with manipulations and plaster casts changed every 14 days, holding the foot in marked abduction and as much dorsiflexion as possible at the ankle in the last cast. This treatment is followed by lengthening the tendo Achilles when dorsiflexion of the ankle is less than 15 degrees. A percutaneous tenotomy can be performed until one year of age. [More recently, Dr. Ponseti mentioned tenotomies done later than one year, up to at least 18 months of age] The last plaster cast is left on for three to four weeks. When the cast is removed, shoes attached in external rotation to a bar are worn at night and with naps, until the child is about four years old. " " To prevent further relapses, the tendon of the tibialis anterior muscle is transferred to the third cuneiform in children over two-and one-half years of age, if this muscle tends to strongly supinate the foot. Often this supination takes place when the medial naviculare displacement is not fully corrected and the AP talocalcaneal angle is under 20 degrees. Transfer of the tibiaiis anterior tendon averts further relapses, maintains the correction of the heel varus, improves the anteroposterior talocalcaneal angle, and thus greatly reduces the need for medial release operations. The tibialis anterior tendon transfer is an easy operation and much less damaging to the foot than the release of the tarsal joints. Joint releases are needed when the deformity recurs in spite Of the tibialis anterior transfer. The tibialis anterior tendon should never be split so as to not lose its eversion power, nor should it be transferred to the fifth metatarsal or to the cuboid, since this would excessively evert the foot, causing severe foot pronation and heel valgus. " CONCLUSION " Since I developed this method of treating clubfoot 50 years ago, only an occasional posterior release operation of the ankle and subtalar joints has been necessary. In the 90 patients I treated in recent years, four patients required surgery: one posterior release of the ankle, and three anterior tibialis tendon transfers to the third cuneiform combined with a lengthening of the tendo Achilles.
