Abstract
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.
