Current study was planned to evaluate effects of eggshell-derived hydroxyapatite (eHA) on healing of radius bone gap in rabbits. Hydroxyapatite was prepared previously from avian eggshell using hydrothermal method and applied to fill an experimentally induced (1 cm) gap at the mid shaft of the radius bone reaching marrow cavity in fifteen male rabbits using left forelimbs as a treated group, while in the right forelimbs the induced bone gaps left without additives and considered as a control group. The clinical, macroscopical, radiological and histopathological parameters indicated a significantly differences in bone growth and complete bridging the bone gaps between treated and control groups at intervals (4, 8 and 12) weeks post operation. In addition to well incorporation of eHA powder with the bone gap in treated groups. In conclusion avian eHA powder considered as a good biocompatible graft material to repair a critical bone gap in rabbit model.
