Abstract:
Objective To evaluate the clinical results of the Ilizarov technique for the treatment of the complex rigid talipes equinovarus deformities.Methods From July 2005 to July 2011,28 patients (41 feet) with rigid talipes equinovarus deformities which had been corrected with the Ilizarov technique were retrospectively analyzed,including 18 males (26 feet) and 10 females (15 feet) with an average age of 15.3 years.According to the classification system proposed by Diméglio,31 feet were categorized as grade Ⅲ,and 10 as grade Ⅳ.We performed corrections with a soft tissue release in 23 feet,and with a limited osteotomy in 18,and then a Ilizarov external fixator was applied.Anteroposterior and lateral X-rays were taken to compare the pre and postoperative data in terms of the angle of plantarflexion and dorsiflexion,the range of motion of the ankle joint,radiological measurements of the talocalcaneal angle.Results All the 28 patients achieved an outpatient follow-up,with an average of 25 months.All patients achieved a plantigrade foot with an almost normal appearance as the fixator was removed after applied for an average of 5.1 months (range,2-14).At the preoperative and final follow-up respectively,the angle of dorsiflexion of the foot was -45.0°±12.0° and 9.5°±5.5°,the angle of plantarflexion was 67.0°±14.0° and 45.5°±7.8°,talocalcaneal angle was 6.5°±4.5° and 22.5°±5.5° in anteroposterior radiograph and 5.5°±11.0° and 40.6°±8.5° in lateral radiograph.Spastic ischemia occurred in one foot and relieved by a slower distraction rate.Wire-hole infections occurred in 5 feet and treated by dressing changs,wire tract altering and antibiotic therapy,finally the infections were controlled.Deformity relapsed in one foot three months after the device was removed,then corrected with an additional fixator application and has not recurred till the final follow-up.Toe contracture and residual deformity occurred in 5 feet and 3 feet,respectively.Conclusion The Ilizarov technique is an effective method for correction of complex rigid talipes equinovarus deformities,with which the appearance and function of the foot could be kept as much as possible,and without impact on food development.
