Dynamic creep behavior of acrylic bone cement.
Recent studies concerning the fixation of cemented total hip arthroplasty (THA) have led to new hypotheses about the dynamic, long-term failure mechanisms leading to prosthetic loosening. As a result, the long-term mechanical behavior of acrylic bone cement has gained more interest since little is known about these properties. In this study, the dynamic, compressive creep deformation of acrylic...
متن کاملMixing of Acrylic Bone Cement – Cu
Dunne, NJ, Daly, C, Beverland, D Queens University of Belfast, Belf Musgrave Park Hospital, Belfast Introduction It has been shown that acrylic bone cement is weakened by its porosity, which enhances the formation of microcracks that contribute to major crack propagation . It has also been observed, that mixing procedures play a significant role in determining the quality of bone cement produce...
متن کاملCardiovascular effects of implanted acrylic bone cement.
A pilot study has shown that there is usually but not invariably a fall in systemic arterial blood pressure within 90 seconds of implanting acrylic cement into the femoral shaft during hip arthroplasty. There is usually no change in arterial blood pressure on implanting acrylic cement into the acetabulum. The observed hypotension may be due to absorption of monomer or additives into the circula...
متن کاملFracture properties of an acrylic bone cement.
This study investigated experimentally the fracture properties, i.e., the fatigue strength, the resistance to crack propagation and the fracture toughness, of an acrylic bone cement (Cemex RX). The mean endurance limit was determined following the staircase method. The endurance limit was estimated at 9.2 MPa. The fatigue crack propagation rate was measured according to the ASTM E647 standard. ...
متن کاملAutonomic healing of acrylic bone cement.
Self-healing in orthopedic bone cement is demonstrated with a novel thermoplastic solvent-bonding approach. Low toxicity solvent-filled microcapsules, embedded in a commercial acrylic bone cement matrix, enable recovery of up to 80% of the virgin fracture toughness of the cement at room and body temperature conditions without external stimuli or human intervention.
