Retirada percutânea de enxerto ósseo autólogo / Percutaneous harvesting of autogenous bone graft

A surgical technique developed on cadavers allows for the percutaneous harvesting of cancellous antogenous bone graft from the distal femoral and proximal tibial metaphysis, by means of a specially designed trephine, a guide, and a helical harvester. This technique is quick and effective, poses minimal local damage, and provides readily usable tittle bone fragments.
