Osseointegration potential for heat treated 3D Ti6Al4V scaffolds seeded with mysenchymal stem cells in vitro
… of artificial joints occurs due to the loss of implant fixation. By implementing a 3D porous structure at the bone-implant interface, the ingrowth of bone will permit better and stronger interlocking of the implant to prevent loosening. In this study, it is hypothesized that the seeding of 3D …

Proof of Concept and Evaluation of a Novel Implant Device for Plantar Plate Repair
… repair using a two-piece snap fitting permanent implant. This novel technique was reduced to practice and required further experimental analysis of its functional capacity to inform future development. Two methodologies were used to evaluate the novel implant device designed for plantar plate …

Characterization and computational modelling of acrylic bone cement polymerisation
… produce accurate and reliable predictions of implant behaviour. Acrylic bone cements have been used as a method of fixation for over 50 years but despite improvements in cement handling techniques and numerous attempts to improve the mechanical properties of the cement in other ways, the …

Computational simulation of bone remodelling post reverse total shoulder arthroplasty
… architecture - a process termed remodelling. Implanted orthopaedic devices can significantly alter the loading on the surrounding bone. In addition, these devices rely on bone ingrowth to ensure secure implant fixation. In this project, a computational model that accounts for bone remodelling …

Validation of numerical prediction of bone ingrowth into cementless implants
… and this led to the development of cementless implants. These implants depend on the ingrowth of bone into a porous coating, to produce a durable method of implant fixation which the normal bone turnover process will maintain. One of the problems with cementless implants is that the type and …

Osteoarthritis Induced Glenoid Morphology and Bone Quality: An Evaluation of Augmented Glenoid Components
… bone loss that may compromise early component fixation and support. The two common morphologies, symmetric and asymmetric erosion, were characterized by bone density and morphology, and assessed on the basis of bone removal and bone quality in the context of augmented glenoid components. The …

Design and Development of a Novel Expanding Pedicle Screw for Use in the Osteoporotic Lumbar Spine
… designs often do not provide adequate fixation in osteoporotic spines. The objective of this thesis was to develop a novel expanding screw for use in osteoporotic lumbar pedicles. Helical screws capable of expanding post insertion were built on a rapid prototype machine. A materials …
