Mechanical Properties of Acrylic Bone Cement Containing the New Soluble Contrast Medium - Iohexol Hexaacetate
ثبت نشده
چکیده
INTRODUCTION Acrylic bone cements, used in arthroplasty, incorporates contrast media to make them radiopaque and visible on X-ray images. However, today’s particulate contrast media cause three disadvantages to the acrylic bone cement, namely; third body wear, decreased mechanical properties and reduced biocompatibility. Iohexol hexaacetate (IHA) is a new iodide based non-ionic contrast medium, and is a pro-drug of the clinically used contrast medium iohexol. This new contrast medium is molecularly dissolved in acrylate monomer and hence not a particulate contrast medium. This investigation is the first to determine the fatigue properties of an acrylic bone cement containing iohexol hexaacetate. This study also investigates the compressive, tensile and flexural properties.

Currently there is no reliable objective method to quantify the setting properties of acrylic bone cements within an operating theatre environment. Ultrasonic technology can be used to determine the acoustic properties of the polymerising bone cement, which are linked to material properties and provide indications of the physical and chemical changes occurring within the cement. The focus of th...

The initial composition of acrylic bone cement along with the mixing and delivery technique used can influence its final properties and therefore its clinical success in vivo. The polymerisation of acrylic bone cement is complex with a number of processes happening simultaneously. Acrylic bone cement mixing and delivery systems have undergone several design changes in their advancement, althoug...
متن کاملThe behavior of novel hydrophilic composite bone cements in simulated body fluids.
Composite bone cements were formulated with bioactive glass (MgO--SiO(2)--3CaO. P(2)O(5)) as the filler and hydrophilic matrix. The matrix was composed of a starch/cellulose acetate blend (SCA) as the solid component and a mixture of methylmethacrylate/acrylic acid (MMA/AA) as the liquid component. The curing parameters, mechanical properties, and bioactive behavior of these composite cements w...
متن کاملValidation of the Small Punch Test Technique to Measure the Mechanical Properties of Acrylic Bone Cement
Introduction The main function of acrylic bone cement is to transfer loads from the prosthesis to the cancellous bone or increase the load carrying capacity of the surgical prosthesis. If the imposed stresses are greater than the load carrying capability, then cement fracture may occur resulting in failure of the joint replacement. The fracture of the cement mantle and subsequent premature loos...
