Conversion of the monocortical iliac bone graft to the three-dimensional prism bone graft

This is a single case report and demonstrates that a successful result can be obtained with this technique. Although the prism bone graft technique seems to offer a solution to a potential rather than a real problem, it offers a thick and three-dimensional cortico-cancellous bone graft without violating the iliac crest. Thus, the risk of serious complications resulting from the tricortical iliac crest graft or bicortical full thickness graft harvesting can be eliminated. Moreover, epiphysis of the immature iliac crest can be preserved in a growing child.
