[Microscopic studies of long bones in rabbits following osteosynthesis using self-stretching metal plates]

Histological changes are described after the application of metal gutter plates to fractured and non-fractured thigh-bones of rabbits. The control group was the un-operated side of the same animal. The cortical part of the non-fractured thigh showed a partial atrophy below the inflexible binding. Neogenesis of immature bone-tissue was observed simultaneously in the cortical part below the metal plate and opposite of this side. Altogether the cortical part of the bone was enlarged through that. Neogenesis of spongy substance was observed exclusively in the area of the regeneration of bone tissue below the metal plate. Processes of regeneration through the healing of the bone tissue predominated in the microscopic findings of the thigh-bone after osteotomy and following osteosynthesis by means of a metal gutter plate.
