A method and implant for surgical manipulation of bone consist of methods and devices to sample bone (21 and 23) and marrow, (22) and perform skeletal surgery from the inside of the bone. The method uses a hollow cylinder (13 or 15) inserted permanently or temporarily into a drill hole in a bone which acts as a port. To this port, adapters (27) can be used to guide fiber optics (31); surgical devices, such as rotating cutters (32); and aspiration or infusion catheters (33). The ability of the insert (13 or 15) to seal in bone allows the collection of tissue under sterile conditions for transplantation to other sites in the patient. The aspiration and collection capability of this method and device allows the aspirate to be processed aseptically, to be concentrated to its vital components, and combined with donor or synthetic bone material for the treatment of bone at a distant skeletal site. This distant site might be accessed with the insert (13 and 15) and infusion catheter (33) or with conventional surgical technique.
