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 ...

The invention relates to a so-called bone cement, e.g. based on polymethylmethacrylate, polystyrene or copolymers, whose particles comprised of e.g. polymerizate, additives and/or contrast media have a globular, preferably spheroidal, shape and form the powdery constituents.

In the early sixties Sir John Charnley presented the preliminary results of a new method for the fixation of joint prostheses to bone (Charnley 1964a,b, 1970). The idea was to distribute the contact stresses between the implant and the bone over a large area by means of a filler material, called bone cement and consisting in self-curing ...

If we are to contemplate total hip replacement in adults as young as 45 years of age with the idea of 25 years of trouble-free life ahead, it is necessary to hold definite opinions on the histological nature of the bone-cement interface. With the exception of some published observations of the author(10, 11) the literature so far contains very little ...
