A New Reversible Method of Epiphysiodesis-An Experimental Study in Rabbits

Lower limb discrepancy and angular deformities are among the most common orthopedic problems in pediatrics. All methods for correction of these deformities are irreversible and the epiphyseal growth plate is arrested. Current study describes a new reversible method of epiphysiodesis. At the first step, we decided to examine angular deformity of the knee. Seven New Zealand white female rabbits with three-week-old age were selected for this study and used a technique of tension band wiring for home epiphysiodesis in the distal of right femur of rabbits. Then comparisons were between operating lower limb as case group and non operated limbs as control group Angular deformity rates had a statistical significant difference between two group p<0.0001. No pathological changes appeared in growth plate in two groups grossly and microscopically. Finding of study revealed that the ability of this technique will have potential in treating angular deformities without jeopardizing the future growth potential of the physis.
