Clubfoot deformity is the most common congenital musculoskeletal disorder (1). Approximately one in one thousand people are born with at least one clubfoot; between 150,000 and 200,000 babies are born with a clubfoot each year (2). Eighty percent of these cases occur in developing countries, and the majority is left untreated. When infants are treated with a non-invasive casting technique pioneered by Ignacio Ponseti M.D., they generally can be “cured” with relative ease. In the United States, 97% of patients given this treatment can walk successfully and are able to live normal lives (3). The Ponseti Method requires several plaster casts but either no or minimal surgery, can be taught fairly easily not only to doctors but also to healthcare workers, nurses, and other people who have some knowledge and training in healthcare. Also, it requires plaster casting, making it an inexpensive treatment. Dr. Ignacio Ponseti first performed his non-invasive treatment in 1949, but didn't publish his results until 1963. Two more papers, published in 1979 and 1995 described the long-term outcomes of treatment. In 1996 Oxford Press published a book detailing his approach. Although the treatment has always had high success rates, a lack of publicity prevented it from becoming more widely used until the late 1990s. Its basic mechanism consists of a series of plaster casts and manipulations that gradually reshape the foot around a fixed talus to obtain correction. Generally, between five and seven casts are required. The casts extend from the toes to the upper thigh and hold the knees at a right angle. One of the most important aspects of this method is timing: infants can be given treatment starting at seven days old and ideally should begin treatment before reaching eight months of age. Brazil, Uganda, Malawi and Chile now have official national programs, which are sponsored by each country's Ministries of Health, in which clinics in each country treat clubfoot disorder using the Ponseti Method. China set up a national program in 2005, but with a population of 1.3 billion people, it will take several years to complete the training. The prevalence of the Ponseti Method varies in the sixty other countries with healthcare workers trained in the treatment. This talk will review the principles of treatment and focus on results of recurrence after initial treatment with the Ponseti Method

Introduction. The Ponseti regime was introduced in Swansea in 2003 for the treatment of congenital talipes equinovarus (CTEV). The aim of this retrospective cohort study was to compare children treated with this regime with a historical group treated traditionally before then. Materials and Methods. Sixty children (89 feet) were treated with the Ponseti regime between 2003 and 2010. Their notes were compared with notes from 12 children (21 feet) treated between 1995 and 2002. Clinic attendance for serial manipulation and immobilisation (strap/cast) was compared using a two-tailed Mann Whitney U test. Major release surgery was compared using a two-tailed Fisher's Exact test. Results. Children in the historical cohort presented when they were 0–174 days old (median 1 day). They attended 3–35 times (median 22) for serial manipulation and strapping/ plasters. Major release surgery was undertaken on 14 feet (66.7%) when the children were 6–39 months old (median 9 months); 7 had revision surgery. The Ponseti cohort presented when they were 0–73 days old (median 10 days) and attended outpatients 2–19 times (median 7) for serial manipulation and casting. An Achilles tenotomy was undertaken in 54 feet (60.7%) when the children were 45–184 days old (median 71 days) and major release surgery in 17 feet (19.1%) when the children were 10–66 months old (median 21 months). Four children had revision surgery. Discussion. There is a significant reduction in outpatient attendances (Ua = 1313, p = <0.0001) for serial manipulation and reduced rate of release surgery (p = 4.56 × 10. −5. ) since the implementation of the Ponseti regime. The rate of revision surgery in both groups was not significant (p = 0.15), although these samples were small. Conclusion. The Ponseti regime is an effective initial treatment for infants with CTEV compared with traditional treatment. It has decreased the number of clinic attendances and the rate of major release surgery

Background. Treatment of arthrogrypotic clubfoot (AC) presents a challenging problem. Over time many different methods have been proposed, with variable rates of success, recurrence and other complications. In this study we describe our 20-year experience in treatment of AC. Materials and methods. Between 1996 and 2016, 165 AC in 90 children (51 males and 39 females) were treated in our department. Their mean age was 7.6 years (3 months-16 years). Ponseti casting and Achilles tendon release (PCATR) was performed on 38 children (68 feet) and soft tissue release and casting (STRC) on 35 children (67 feet). The remaining 17 children (30 feet) underwent wide soft tissue release and correction using the Ilizarov method (STRIL). The results of each subgroup were graded according to clinical (pain, foot appearance, residual deformities, walking and standing status and shoe modifications) and radiological (anteroposterior and lateral talocalcanear angles, the angle between longitudinal axes of talus and the first metatarsal and the position of talus in the lateral view) criteria. Results. The average follow up was 6.4 (2–10) years. Results were excellent (plantigrade, painless, properly loaded feet, without deformities, adapted to common shoes) in 56 PCATR group feet, 59 STRC group feet and 23 STRIL group feet. Good results (required orthopaedic shoes) were obtained in 10 PCATR group feet, 6 STRC group feet and 7 STRIL group feet. Fair results (residual temporary pain and/or mild deformity) presented 2 PCATR group feet and 1 STRC group foot, while bad results (reoccurrence of clubfoot) were found in 1 STRC group foot. Conclusions. On the basis of our 20-year clinical experience we believe that pediatric AC can be successfully treated with PCATR in the age of less than 1 year old (y.o), with STRC between 1–5 y.o. and with STRIL in children over the age of 5 y.o

We investigated 60 patients (89 feet) with a mean age of 64 years (61 to 67) treated for congenital clubfoot deformity, using standardised weight-bearing radiographs of both feet and ankles together with a functional evaluation. Talocalcaneal and talonavicular relationships were measured and the degree of osteo-arthritic change in the ankle and talonavicular joints was assessed. The functional results were evaluated using a modified Laaveg-Ponseti score. The talocalcaneal (TC) angles in the clubfeet were significantly lower in both anteroposterior (AP) and lateral projections than in the unaffected feet (p < 0.001 for both views). There was significant medial subluxation of the navicular in the clubfeet compared with the unaffected feet (p < 0.001). Severe osteoarthritis in the ankle joint was seen in seven feet (8%) and in the talonavicular joint in 11 feet (12%). The functional result was excellent or good (≥ 80 points) in 29 patients (48%), and fair or poor (< 80 points) in 31 patients (52%). Patients who had undergone few (0 to 1) surgical procedures had better functional outcomes than those who had undergone two or more procedures (p < 0.001). There was a significant correlation between the functional result and the degree of medial subluxation of the navicular (p < 0.001, r² = 0.164), the talocalcaneal angle on AP projection (p < 0.02, r2 = 0.025) and extent of osteoarthritis in the ankle joint (p < 0.001).

We conclude that poor functional outcome in patients with congenital clubfoot occurs more frequently in those with medial displacement of the navicular, osteoarthritis of the talonavicular and ankle joints, and a low talocalcaneal angle on the AP projection, and in patients who have undergone two or more surgical procedures. However, the ankle joint in these patients appeared relatively resistant to the development of osteoarthritis.

Rocker bottom deformity may occur during the conservative treatment of idiopathic congenital clubfoot. Between 1975 and 1996, we treated 715 patients (1120 clubfeet) conservatively. A total of 23 patients (36 feet; 3.2%) developed a rocker bottom deformity. It is these patients that we have studied. The pathoanatomy of the rocker bottom deformity is characterised by a plantar convexity appearing between three and six months of age with the hindfoot equinus position remaining constant. The convexity initially involves the medial column, radiologically identified by the talo-first metatarsal angle and secondly by the lateral column, revealed radiologically as the calcaneo-fifth metatarsal angle. The apex of the deformity is usually at the midtrasal with a dorsal calcaneocuboid subluxation. Ideal management of clubfoot deformity should avoid this complication, with adequate manipulation and splinting and early Achilles’ percutaneous tenotomy if plantar convexity occurs.

Adequate soft-tissue release provides satisfactory correction for rocker bottom deformity. However, this deformity requires more extensive and complex procedures than the standard surgical treatment of clubfoot. The need for lateral radiographs to ensure that the rocker bottom deformity is recognised early, is demonstrated.
