[Split tibialis posterior tendon transfer on peroneus brevis for equinovarus foot in CP children].

Abstract
Equinovarus deformity of the foot is a result of the muscles imbalance in which inventors of the foot, mostly posterior and anterior tibialis muscle, overpower evertors. In children with cerebral palsy untreated spastic equinovarus deformity may cause severe fixed foot deformity and painful callosities under metatarsal heads and on the lateral side of the foot. The gait pattern becomes less effective and needs more energy. The study group consisted of 154 children with cerebral palsy treated in our Clinic by the multilevel soft tissue surgery. For foot problems 136 children needed surgical intervention. In 19 ambulatory patients, with hemiplegia or diplegia, split tibialis posterior tendon transfer together with tendo Achilles lengthening and plantar aponeurectomy were performed. The study was based on clinical examination, parents' questionnaire, radiology and gait analysis at least one year after surgery. The mean follow up was 4.6 years. The functional improvement was observed in 17 (89%) children with tendon transfer. At the last follow up those patients were brace free, with plantigrade foot while walking (without DAFO orthesis) and normal shoes were used. All painful callosities disappeared. On a standing AP X-ray adequate correction of the hindfoot-forefoot relation was achieved in 14 (74%) cases. Persistent equinovarus deformity over 10 degrees was observed in 2 cases. Those patients underwent additional bone surgery. With a properly planned approach the split tibialis posterior tendon transfer can bring good clinical and functional results in CP children with equinovarus deformation. We recommend this procedure in early stage of the deformity what can eliminate more harmful triple arthrodesis in severe deformities.
