Thermal analysis of bone cement polymerisation at the cement–bone interface

Journal of Biomechanics, 2004
The 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.

Contrast bone cement

Journal of Orthopaedic Research, 1983
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.

Biodegradable bone cements

Der Orthopäde, 1997
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.

Osteotransductive bone cements

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 1998
Abstract Calcium 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.

The Preparation of Bone Cement

British Journal of Perioperative Nursing (United Kingdom), 2001
In this second in a series of four articles, Rebecca Eveleigh explains why it is essential for bone cement to be properly prepared, mixed and delivered.
