Abstract
This thesis presents the development of a new class of swelling-type materials capable of self-fixation in bone by absorption of surrounding body fluids. Fixation in these materials is achieved within days after implantation by an expansion-fit mechanism. Although swelling can be achieved in principle using any hydrophilic material, the underlying goal of this study was to develop a swelling-type material system capable of self-fixation without loosing its load-carrying capabilities. The material for this class of self-anchoring implants is based on a cross-linked random copolymer of acrylic acid (AA) and methyl methacrylate (MMA). By varying the relative amounts of these two constituents, the material was designed to have the desired levels of water affinity. For high load-bearing applications, the cross-linked copolymer was reinforced with AS-4 carbon and Kevlar 49 fibers.
