Double-elevating osteotomy of tibiae in the treatment of severe cases of Blount's disease.

The results of operative correction of 13 cases of tibia vara in 10 children with advanced infantile Blount's disease are presented. All of the children were operated by "double-elevating" osteotomy. An essential element of this procedure was the reconstruction of the horizontal level of the medial tibial plateau. The average follow-up after treatment was 8 years 1 month. We recommend this method of osteotomy in cases of considerable depression of the medial tibial condyle with the defect of epiphyseal bone and as a bone bridge between the metaphysis and the epiphysis.
