AbstractThe effects of adding 1.0 cc of aqueous methylene blue dye as a visual contrast agent to a standard 40 g pack of acrylic bone cement are determined. These cements are evaluated: Simplex P (Radiopaque), Zimmer Bone Cement, and Zimmer LVC Bone Cement. Seven tests were performed.

Osteotransductive bone cements
Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 1998Calcium phosphate bone cements (CPBCs) are osteotransductive, i.e. after implantation in bone they are transformed into new bone tissue. Furthermore, due to the fact that they are mouldable, their osteointegration is immediate. Their chemistry has been established previously.

Bone cements are used to treat compression fractures, fill bone defects and improve implant fixation in osteoporotic patients through reinforcement of weak bone. When the fracture repair is complete the bone cement ideally should degrade. In general, calcium-phosphate bone cements are biodegradable and can fulfill this temporary function.

Poly (methylmethacrylate) (PMMA) bone cement, used to fix implants into the bone, produces good surgical results if used correctly. However, prostheses do eventually become loose and the breakdown of the cement mantle is a factor in this failure.

Intracardiac bone cement embolism
Heart, 2010A 78-year-old woman presented with progressive shortness of breath for a couple of months. She underwent percutaneous vertebroplasty using polymethylmethacrylate because of a compression fracture of the T8 vertebral body 6 years ago. Although she had mild …

Thermal analysis of bone cement polymerisation at the cement–bone interface
Journal of Biomechanics, 2004The two major problems that have been reported with the use of polymethylmethacrylate (PMMA) cement are thermal necrosis of surrounding bone due to the high heat generation during polymerisation and chemical necrosis due to unreacted monomer release. Computer models have been used to study the temperature and monomer distribution after cementation.

Nondestructive evaluation of bone cement and bone cement/metal interface failure
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2009AbstractTo quantify the failure mechanisms related to the loosening of cemented hip joint replacements, novel techniques, capable of monitoring, nondestructively, the initiation and progression of failure duringin vitrofatigue tests, were employed. Fatigue testing of model cement and cement‐stem test pieces was monitored using acoustic emission (AE ...

Bone Bonding Ability of Bioactive Bone Cements
Clinical Orthopaedics and Related Research, 1997The bone bonding ability of three types of bioactive bone cement A, B, and C consisting of glass or glass ceramic powder and bisphenol-alpha-glycidyl methacrylate resin was evaluated. Type A contained MgO-CaO-SiO2-P2O5-CaF2 glass powder; Type B, MgO-CaO-SiO2-P2O5-CaF2 glass ceramic powder; and Type C, MgO free CaO-SiO2-P2O5-CaF2 glass powder ...

Repair of segmental bone defects using bioactive bone cement: Comparison with PMMA bone cement
Journal of Biomedical Materials Research, 1999We developed a bioactive bone cement (BABC) that consists of apatite and wollastonite containing glass ceramic (AW-GC) powder and bisphenol-A-glycidyl dimethacrylate (Bis-GMA) based resin. In the present study, the effectiveness of the BABC for repair of segmental bone defects under load-bearing conditions was examined using a rabbit tibia model ...
