Corin’s OPS™ technology now enables the surgeon to understand the individual motion profile of each patient before their surgery. This gives the surgeon the information required to identify, customise and deliver a personalised total hip replacement, specifically designed to optimise biomechanics and functional joint performance. This is driven by a simple imaging protocol, featuring Simpleware software, used to generate key inputs to simulate the unique way in which patients perform their normal everyday activities. The system outputs then provide the surgeon with an accurate laser guided alignment system which allows the patient-specific implant orientation to be reliably achieved during surgery.
Specific landmarks are taken on each patient’s skeletons, whereby Simpleware ScanIP is used to segment CT images of patient’s bones to create 3D models – the location of key landmarks can then be identified within the CT reference frame, with the appropriate bony landmarks, implant positions and bone models fed into the simulation. Scripting tools in Simpleware are used to automate a significant amount of this process and save time for the Corin production team working on the image data.
Traditionally, surgeons use an AP (anterior-posterior) X-ray of their patients to plan the implant arrangement and approximate sizes for surgery. Using Simpleware software, the implant geometries can be imported to an individual patient’s CT reference frame, allowing Corin engineers to view the implants within a 3D environment and allowing more detailed planning to be executed compared to traditional 2D X-ray-based templating.
