Abstract
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.
Highlights
Were following up birthday and everything about animal was recorded on an identification sheet for each
The aim of this study was to describe a new technique for treatment of lower limb discrepancy or angular deformities that physeal growth plate rate was under control of the surgeon
We examined this method for temporary cessation of growth in knee angular deformities in Rabbit model
Summary
Were following up birthday and everything about animal was recorded on an identification sheet for each. Epiphyseal stapling, Phemister technique and percutaneous cauterization or drilling are used to correct these conditions[3, 5, 8, 9]. These methods have many complications and achieve permanent complete closure of the growth plates and arrest it[4, 6, 7, 11,12,13,14]. Orthopedic surgeons like to correct the lower limb discrepancy or angular deformities with the minimum of complication and maximum of efficacy. A set which composed of a thin tube with two parallel pins in one side and one screw on the other side can be placed one centimeter above the growth plate by passing the MATERIAL AND METHODS
