Abstract:
Bone is a heterogenous and anisotrophic material exhibiting elastic, viscoelastis and plasticproperties. A considerable amount of information is now available regarding biomechanical properties and mechanisms of fractures of mature long bones, but less is known about the properties of the growing bones. In order to assess the biomechanical properties under tension, rabbits growing bones were loaded with Instron Modal 1,000 until fracture occurred. Two hundred tibiae of 100 New Zealand white immature rabbits were divided into 6 experimental groups according to maturity and size. Group I-R(40 right tibiae of 1-month old rabbits), Group I-L (40 left tibiae of 1-month old rabbits), Group II-R(20 right tibiae of 3-month old rabbits), Group II-L (20 left tibiae of 3-month old rabbits), Group III-R(40 rigth tibiae of 5-month old rabbits), and Group III-L(40 left tibiae of 5-month old rabbits). The following results were obtained. 1. Fracture type was transverse.or nearly transverse in 170 out of the total 200 tibiae(85%).
