Fracture 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 کاملSurface studies on acrylic bone cement.
Poly(methyl methacrylate) (PMMA) is used to fill the gap between the prosthesis and the surrounding bone in cemented arthroplasties. Biocompatibility problems related to bone cement application limit the clinical success of these cemented arthroplasties. Being the cement surface in close connection with the living bone, it is reasonable to assume that surface properties such as, surface composi...
متن کاملBone marrow modified acrylic bone cement for augmentation of osteoporotic cancellous bone.
The use of polymethylmethacrylate (PMMA) cement to reinforce fragile or broken vertebral bodies (vertebroplasty) leads to extensive bone stiffening. This might be one reason for fractures at the adjacent vertebrae following this procedure. PMMA with a reduced Young's modulus may be more suitable. The goal of this study was to produce and characterize PMMA bone cements with a reduced Young's mod...
متن کاملPorous Surface Modified Bioactive Bone Cement for Enhanced Bone Bonding
BACKGROUND Polymethylmethacrylate bone cement cannot provide an adhesive chemical bonding to form a stable cement-bone interface. Bioactive bone cements show bone bonding ability, but their clinical application is limited because bone resorption is observed after implantation. Porous polymethylmethacrylate can be achieved with the addition of carboxymethylcellulose, alginate and gelatin micropa...
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...
