Bone grafts are used to treat various disorders, including delayed union and nonunion of fractures,
congenital pseudoarthrosis, and osseous defects from trauma, infection, and tumors. The disadvantages of
allografts, such as disease transmission, have led to the exploration of xenografts as an alternative grafting
material. We used turtle DBM and turtle bone grafts in this study. A critical size defect of 2.5 times diameter
elongation was created in the radial diaphysis of 16 rats in this study. The rats were divided into 4 groups: defect
as control˗, autograft as control+, turtle bone and turtle DBM. The results of radiological, histopathological,
biomechanical and scanning electron microscopic evaluation of groups were compared. The biomechanical and
radiological evaluation shows that there was no significant difference between groups; but histopathological
evaluation shows significant differences between groups in union and cancellous bone. The turtle DBM group
had the same result as control+ and was superior to the other groups.
