摘要

Acrylic bone cements are widely used in orthopedic surgery to fix artificial prostheses in the body osseous structure. One of the most important applications in this area is in Total Hip Arthroplasty (THA). The cement has two main functions: to assure the short and long term anchorage of the implant to the bone, and to allow a better distribution of body loads between the prostheses and the bone (1-3). Nevertheless several adverse effects are associated with the use of bone cements in this field: high temperature of the polymerization reaction may cause thermal necrosis to the adjacent bone (4,5), the release of unreacted monomer, methylmethacrylate (MMA), produces chemical damage in the surrounding tissues, and the shrinkage of the cement upon curing produces gaps in the bone/cement and cement/prostheses interfaces.
