Abstract

Significant limb length inequality in children is a major orthopaedic management problem. Surgical procedures currently employed in the treatment of leg length inequality are often unreliable and subject to many diverse complication. The fact that epiphysiolysis may occur and heal with little consequence is often seen in nature in the form of epiphyseal plate fracture in children. So, in 1969, Ilisarove and Soybelmann reported the successful application of distraction epiphysiolysis to human subject.
The present study concerns the results of the effect of distraction epiphysiolysis and a histologic analysis of this preliminary experimental material is reported. In this study, a total of 10 rabbits was used. Their ages ranged from 1 to 3 months. The turnbuckle type external fixation devices was used as distracter. Under the I.V. anesthesia the fluoroscopic control 0.9mm K-wire in epiphyseal nucleus and 1.1mm K-wire in the distal tibia each were inserted transversely and external fixation devices was applied to the K-wires. Postoperatively, the animal was sacrificed 10 weeks following operation. Tibia length was determined by measurement of radiographs. Specimens stained with H-E stain were observed during 10 weeks after operation.
Through these examination, following results were obtained.
1. After epiphyseal distraction, separation always occurred in the zone of the hypertrophic cartiage, achieving the maximum lengthening up to 67 mm for 10 weeks.
2. No premature fusion of epiphyseal plate and bone bridge formation occurred in any cases. As a complication, we have experienced 1 superficial infection and 1 deep infection around the pin and 1 tibia shaft fracture among the 10 cases.
3. After 10 weeks of distraction, the microscopic appearance of the articular cartilage revealed some fraying and disintegration of the surface cartilage without flexion and extension deformity.
So distraction epiphysis as a method of limb lengthening is recommended in leg length inequality.
