The effect of autogenous nonvascularised periosteum transplantation on bone healing - an animal study

The purpose of this study 1s to evaluate the effect of Fresh Frozen allograft on a large-sized tibia defect 111 a rabbit model when a non vascularised periosteum sleeve is wrapped around it. This is an animal experiment, a pilot study and descriptive in nature carried out in MEDICAL SCHOOL. UNIVE...

Nine( 9) rabbits were divided into three groups (A,B,C) and three (3) other rabbits were used as control group (group D). A 3 em segment of the (R) tibia shaft was removed and the defect was then replaced with bare allograft and stabil ized with Kirschner wire (K wire) s ize 2 mm. The leg was immobilised with Plaster of Paris. In the groups A,B and C the a llogra ft segments were wrapped circumferentially by the free non-vascularised periosteal flap that was harvested from the (L) tibia.

The results observed m the rabbits where there were periosteum used to wrap around the entire segment of allografts, there were union at both ends of the allografts seen at the end of 4th and 6th weeks. At the end of 2nd week both ends of the allograft were still seen not united, but some callus was seen to form at the fracture ends.
