[The experimental study of repairing bone defects with allogeneic bone matrix gelatin and plaster].
OBJECTIVE
To study the function of the composite of bone matrix gelatin(BMG) and plaster in the repairing process of bone defects.


METHODS
Sixteen New Zealand rabbits which were defected in corpus radii were made as implant zone of bone. Sixteen sides of radii were implanted with the composite of BMG and plaster as experimental group. Others were implanted with BMG(8 sides) and bone stored in alcohol(8 sides) as control groups. The repairing process in bone defects were observed by X-ray and histological examination.


RESULTS
There was an obvious osteogenesis in experimental group. The defects of radii were almost healed at 12th week after operation. There were osteogenesis in both control groups, but the repairing process was slower than that of the experimental group.


CONCLUSIONS
The composite of BMG and plaster is a good material for bone transplantation.
