ABSTRACT:: The resistant clubfoot deformity presents a significant challenge. Several corrective procedures have been described, with the goal to provide a pain-free, plantigrade foot. The Ilizarov method of external fixation and gradual distraction has been reported as an alternative to conventional techniques. Previous reviews have concluded that this method can provide satisfactory correction and outcome. This study presents a review of 21 resistant clubfeet in 17 patients, who had undergone previous surgery, treated with Ilizarov external fixation and gradual distraction by 1 of 2 surgeons. Outcome measures were graded based on function and presence of residual deformity: (a) excellent (painless, plantigrade foot, with no functional limitations); (b) good (plantigrade foot in a patient able to ambulate long distances with mild pain; (c) fair (mild residual deformity, required bracing, and/or had some functional limitations but an active life); and (d) poor (significant residual deformity, pain, and activity limitations). Radiographic measures of the talocalcaneal and talo-first metatarsal angles were compared preoperatively and postoperatively. At an average follow-up of 6.64 years (range, 2.25-10.50 years), 9.5% (2) achieved an excellent result; 4.8% (1), good; 33.3% (7), fair; and 52.4% (11), poor. All 11 of the feet graded poor required revision surgery at an average of 5.63 years postoperatively (range, 2.67-10.2 years). Only the talo-first metatarsal angle displayed a clinically and statistically significant correction. We conclude that the Ilizarov method for treatment of resistant clubfoot deformities results in poor outcome associated with residual or recurrent deformity, often requiring revision surgery.
Consider this method cautiously ... there have been at least 3 children in the internet community suggested for this method who were taken to another physician for a second opinion and achieved full correction without the necessity of this proceedure - 2 with casting only and one with casting and ATTT (which carries less infection risk and shorter term of treatment).

This study presents the clinical and radiographic outcomes of 6 feet (4 patients) with relapsed idiopathic clubfoot that were treated with a combination of subtalar release and the Ilizarov method. The mean patient age at the time of the surgery was 7.4 years (range, 4.5-10.5 years), and the mean follow-up was 5.1 years (range, 2.0-7.3 years). All cases achieved a plantigrade foot, better walking ability, and parental satisfaction with the result. Ankle joint range of motion increased from a mean of 17 degrees (range, 10-30 degrees ) preoperatively to 45 degrees (range, 35-65 degrees ) at final follow-up. The talocalcaneal angle improved from a mean of 26 degrees (range, 15-34 degrees ) preoperatively to 55 degrees (range, 47-65 degrees ) at follow-up. The mean tibiocalcaneal angle improved from 95 degrees (range, 87-115 degrees ) preoperatively to 80 degrees (77-83 degrees ) at follow-up, whereas the talometatarsal angle improved from a preoperative mean of -19 degrees (range, -35 to -10 degrees ) to 3.5 degrees (range, -5 to 7 degrees ) at follow-up. Recurrence was observed in only 1 foot with forefoot adductus, caused by a pin tract infection and early fixator removal. These cases suggest the Ilizarov method combined with subtalar release are beneficial for the treatment of relapsed idiopathic clubfoot.
Treatment with the Ponseti method corrects congenital idiopathic clubfeet in the majority of patients. However, some feet do not respond to the standard treatment protocol. We describe the characteristics and treatment results of these complex idiopathic clubfeet. We identified 50 patients (75 clubfeet) from 762 consecutive patients treated at five institutions. Clinically, complex clubfeet were defined as having rigid equinus, severe plantar flexion of all metatarsals, a deep crease above the heel, a transverse crease in the sole of the foot, and a short and hyperextended first toe. The Achilles' tendon was exceptionally tight and fibrotic up to the middle of the calf. Correction was achieved in all patients by modifying the Ponseti manipulation and casting technique. Correction required an average of five casts (range, 1-10 casts). Two patients (4%) not initially recognized as having complex clubfeet had a posterior release with tendo Achillis lengthening. There were seven relapses that responded to casting. Three patients had a second tenotomy. Modifying the treatment protocol for complex clubfeet successfully corrected the deformity without the need for extensive corrective surgery.
Clubfoot is the commonest congenital deformity in babies. More than 100,000 babies are born worldwide each year with congenital clubfoot. Around 80% of the cases occur in developing nations. We treated 154 feet [mean Pirani score (total) 5.57] in 96 children (78 males, 18 females) by the Ponseti method from January 2003 to December 2005. A prospective follow-up for a mean duration of 19.5 months (range 6-32 months) was undertaken. After six months of treatment the Pirani score was reduced to zero for all patients. The results show that corrective surgery, sometimes multiple, can be avoided in most cases which are usually associated with the development of a stiff, painful foot. Low socio-economic status and illiteracy prevailing in developing nations increases the prevalence of neglected clubfoot that is still harder to correct. Integration into various programs and proper use of available resources can decrease neglected clubfoot and improve chances of successful and timely correction of deformity. Bracing constitutes an important part of treatment and proper motivation and education of the parents mitigates the chances of losing correction. The Ponseti method of correcting clubfoot is especially important in developing countries, where operative facilities are not available in the remote areas and well-trained physicians and personnel can manage the cases effectively with cast treatment only.
The Ponseti method of treating club foot has been shown to be effective in children up to two years of age. However, it is not known whether it is successful in older children. We retrospectively reviewed 17 children (24 feet) with congenital idiopathic club foot who presented after walking age and had undergone no previous treatment. All were treated by the method described by Ponseti, with minor modifications. The mean age at presentation was 3.9 years (1.2 to 9.0) and the mean follow-up was for 3.1 years (2.1 to 5.6). The mean time of immobilisation in a cast was 3.9 months (1.5 to 6.0). A painless plantigrade foot was obtained in 16 feet without the need for extensive soft-tissue release and/or bony procedures. Four patients (7 feet) had recurrent equinus which required a second tenotomy. Failure was observed in five patients (8 feet) who required a posterior release for full correction of the equinus deformity. We conclude that the Ponseti method is a safe, effective and low-cost treatment for neglected idiopathic club foot presenting after walking age.
