Abstract
A surgical technique for the delivery of bone graft to a medullary canal and implantation of a prosthetic device includes placing bone graft into an elongate hollow tube and arranging a plunger having an elongate rod portion into the hollow tube. The hollow tube, bone graft and plunger assembly are inserted into the medullary canal which has been prepared for the assembly by reaming the medullary canal with a reamer corresponding in size to the hollow tube. The hollow tube is withdrawn from the medullary canal while the plunger is pushed into the canal, resulting in bone graft exiting the hollow tube and being packed by the plunger. A trial prosthesis is used to shape the bone graft within the canal for the prosthesis. Space for a cement mantle can be left through the use of an appropriately sized trial prosthesis.
