Researchers at the University of Southampton in the UK say that their MXL project, which uses computational modeling to define the mechanics of an artificial joint, will enable surgeons to ensure successful surgery and fit joint replacements with longer, optimized lifespans. Using a complex interaction of individual anatomy, prosthesis design, sizing, and placement will allow surgeons to support their decision process by reliable, quantitative information on the expected joint mechanics and functional outcome.
The systems created by the MXL project, funded by the European Commission’s Seventh Framework Programme, will enable cost-effective development of robust prosthesis designs. It will also support surgical decision-making to provide a safer route to optimal, functional outcome of joint surgery, independent of the surgeon’s prior experience and training, the researchers say.
They developed a 3D musculoskeletal model, with data on the variations in bone shape and tissue density, which has enabled advanced biomechanical assessment of the joint reconstruction. The development of this specialized software, they claim, allows automated positioning of implants and gives the ability to modify implant size and position to address individual patient needs. Their intention is that this technology will lead to increased patient safety and improved lifespan of joint replacement prosthetics.
The MXL project consortium is now offering this unique technology to interested partners, in order to ensure that their developments are transformed into tangible benefits.
