1. Then they inject bone cement , stabilizing the bone to prevent further collapse. 2. New bone cement formulations require characterization according to ASTM F451. 3. PMMA allowed bone cements to be used for anchorage of head prostheses in the 1950s. 4. More recently bone cement has been use in the spine in either vertebroplasty or kyphoplasty procedures. 5. A prosthesis fixed with bone cement offers very high primary stability combined with fast remobilization of patients. 6. The individual components of the bone cement are also known in the area of dental filler materials. 7. This channel is used to deliver the PTFE bag within which the injected bone cement will reside. 8. During the procedure, bone cement is injected with a biopsy needle into the collapsed or fractured vertebra. 9. The cement that reflected these features was produced by CMW Laboratories Limited and was called CMW bone cement . 10. Bone cement chemically is nothing more than Plexiglas ( i . e . polymethyl methacrylate or PMMA ).
