幼若家兎의 關節軟骨 및 骨端成長板에 Kirschner wire 및 screw 揷入이 미치는 影響에 關한 實驗的 硏究 = An Experimental Study of the Effect of Kirschner-wire and Screw insertion upon the Epiphyseal Plate of the Distal Femur in the Growing Rabbit

다국어 초록 (Multilingual Abstract)

The effect of surgical traumata upon the epiphyseal plate of the growing bone has been controversial among many authors.
The resultant deformity subsequent to the epiphyseal plate injury yields numerous different pattens and any of the explarations of the pathogenesis is also not accepted for all.
Therefore, the author made an experiment to elucidate more clearly the histological changes of the epiphyseal plate of immature rabbits following insertion of Kirschner-wire and screw.
Thirty rabbits weighing 700-1200gm mere divided into 2 groups, as following and the direction of longitudinal insertion form articular surface of the epiphysis into metaphysis of the distal femur.
Group 1: Insertion of Kirschner-wire
Group 2: insertion of screw
The animals were sacrificed at 1,2,4,8, and 10 weeks after the operative procedure and the histological examination of the injured epiphyseal plate of distal femur were made.
The summary of the histological findings were follows:
1. The margin of the epiphyseal plate adjoining the Kirsckner wire showed a new osseous tissue which formed a bony bridge running from the epiphysis to the metaphyseal bony trabeculae.
2. The margin of the damaged epiphyseal plate adjoining the screw revealed new bone formation and the amounts of the reactive new bone is less than Kirschner-wire.
3. Histological findings of the epiphyseal plate showed to be uniform and normal except in the adjacent area of the Kirschner-wire and screw.
