Abstract
Introduction: Recurrent clubfoot deformity continues to present a problem in pediatric orthopedic practice. Because of the complexity of feet deformation, the correction represents a significant challenge even for orthopedists having experience in work with the Ilizarov device.
Materials and Methods: We apply the Ilizarov fixator consisting of a base from two rings on a shin, an anterior support on the foot – the half ring perpendicular to metatarsal bones and a posterior support from the extended half ring attached to the heel. Anterior and posterior supports are attached to the base by standard details of the Ilizarov apparatus and remain unconnected between them. Such a frame design allows independent and simultaneous correction of forefoot and hind-foot deformities. From 1999–2006, 9 patients aged 3–30, 13 feet with recurrent clubfoot were treated with this technique. Three patients were females and 6 were males. Closed correction was perform in 5 cases, mid-foot osteotomy 4 cases triple arthrodesis 4 cases. The average deformity was: forefoot (supination – 30° FFA – 30°) hind foot (supination 35° equinus 40°).
Results: The correction commenced on fourth-seventh day after surgery. Corrections of deformity were achieved in all cases. The average correction period was 8 weeks. Fixation after complete correction was 6–8 weeks. Complications included pin-tract infection 16%, flexion contracture of toes – 87.5%, and severe pain during deformity correction 33%. On mean follow-up of 40 months all patients had good functional outcome.
Conclusion: Our frame variant is easy to compose, requires only standard components and allows good correction of all foot deformities.
