Patient-matched Implants and Tools

Advances in metal artefact reduction Computed Tomography (CT), image analysis and reconstruction, have allowed for computerised modelling of patients’ anatomy. Additive manufacturing has enabled the accurate production of bespoke/patient-matched implants with integral porosity providing a fairly new tool to manage some of the most severe cases in revision hip surgery.

Patient specific instrumentation (PSI) is a modern technique, one of computer-assisted orthopaedic surgery techniques, aiming to facilitate the implantation of the prosthesis. PSI are generated from a pre-operative three-dimensional model, using computed tomography (CT) or magnetic resonance imaging (MRI).
