Ilizarov technique combined with limited adjunctive surgical procedures for correction of relapsed talipes equinovarus in children.

Objective To evaluate the efficacy and safety of using the Ilizarov invasive distraction technique combined with limited surgical operations in the treatment of relapsed talipes equinovarus in children. Methods This retrospective study analysed the outcomes of paediatric patients with relapsed talipes equinovarus who were treated with the Ilizarov technique with moderate open limited soft tissue or bony operations. The International Clubfoot Study Group (ICFSG) classification system score was used to evaluate the deformities before and after surgery. Results The study evaluated 16 feet in 14 patients (nine boys). The correction time ranged from 6 to 12 weeks. The mean duration of frame application was 5.9 months. The gait was improved significantly in all patients. At final follow-up, the mean ankle dorsiflexion and plantarflexion ranges were 8.3° and 34.6°, respectively. The talocalcaneal angle improved from 10.0° preoperatively to 28.3° postoperatively in the anteroposterior plane; and from 4.1° preoperatively to 42.1° postoperatively in the lateral plane. The differences in the angle of plantarflexion, dorsiflexion, range of motion of the ankle joint and talocalcaneal angles pre- and postoperation were significant. Conclusions These current findings suggest that the Ilizarov technique combined with limited surgery effectively corrects relapsed talipes equinovarus in children.
