Characterisation and cohesive zone modelling of adhesives and bone cements used in prothesis fixation surgeries

Abstract

As there is a huge demand for the development and characterisation of proper Adhesives and Bone cements in the field of orthopaedic surgery which is used to fix the Prosthesis.We have taken this opportunity which is available in the field of orthopaedic surgery to characterise the mechanical properties of the Adhesive made of Cyanoacrylate and Bone Cements made of Poly Methyl Methacrylate(PMMA).The basic Static Testings like Tensile and Shear were made on the ASTM standard specimens of Cow Bones which is being fixed using the above mentioned Adhesive and Bone Cements.Almost 30 pairs of bones were machined in order to have the mechanical testings. A comparison study is made between the Adhesives and Bone Cements on it’s efficiency of Adhering to the bone.A Cohesive Zone Model for the bones which is fixed by Adhesives and Bone cements is also developed in ANSYS.
