Special devices and instruments a new instrument for harvesting autogenous cancellous bone

Principle The set of instruments allows harvesting autogenous cancellous bone from the anterior or posterior iliac crest. Special punches (Figures 3 and 4) introduced through rotary movements will detach cancellous bone from its bed and the graft will be secured in the punch through compression. Corresponding pestles will be used to extrude the bone graft while compressing it further. This then supplies small firm cylinders of cancellous bone.
