A bone tissue removal and harvesting device is disclosed and includes a cutting tool with a cutting head, a longitudinal shaft attached to the cutting head and a drive element. A container is located on the end opposite the cutting head for collection of the removed bone. The shaft can be made flexible to permit torsion and/or bending around the longitudinal axis without damage to the bone. During the cutting operation, the bone tissue is simultaneously removed and suctioned through an opening of the cutting head and conveyed through an axial shaft bore for collection in the container. The container is detachably mounted to the drive element and connected to the shaft so as to avoid substantial pressure drops from the cutting head to the container.

A bone anchoring assembly includes at least one fixation plate and at least one bone anchoring element. Each bone anchoring element includes a circular-cylindrical hollow body with an upper end and a lower end, a connecting element that is pivotably mounted to a fixation plate or longitudinal support, an external thread that extends partially along the outer surface of the circular-cylindrical body for anchoring the bone anchoring element into the cortical portion of the bone, and a series of teeth located on the lower end of the circular-cylindrical body for cutting into bone.

Self-cutting, hollow-cylindrical bone anchoring assembly

Combining an implant and cement for prophylactic and/or preventative use for femoral neck augmention. A hole is drilled into the femoral neck. The hole is filled with an uncured filler cement after loose materials have been removed from the hole. Then, an open-ended tube, an implant, having openings through its walls is inserted into the hole and attached to the bone. Finally, additional filler cement is provided under pressure to the inside of the tubular implant. The filler cement flows into spaces in the bone structure via the tube wall openings. A sliding leak-tight fit between the implant and a cement injection tube permits delivery of cement at preselected locations along the implant length. Pressure is maintained until the filler cement has hardened. A strengthening factor up to 3 was measured when osteoporotic bone was strengthened.
