title: The Ilizarov method for the treatment of resistant clubfoot: is it an effective solution?
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.
