The Optimized Positioning System, OPS™, consists of two parts:
- Step 1 – a dynamic, functional and patient specific pre-operative simulation This takes the patient through a range of daily activities to investigate the relationship between their spine, pelvis and femur. The process starts with medical imaging, capturing the unique anatomical geometry of each patient. Inputs are then analysed by an engineering team using specialized software. The simulation then models the predicted in vivo behaviour of the implants to optimize the orientation of the acetabular component. A surgeon report provides detailed information to assist in optimizing the outcome for each patient. Once the orientation is decided a unique guide is 3D printed.
- Step 2 – a patient specific delivery system Before reaming, the unique 3D guide is placed into the acetabulum enabling the chosen orientation to be precisely reproduced, irrespective of the patient’s position on the operating table. During cup impaction the surgeon uses a simple laser guided system to quickly and accurately achieve the optimized orientation.
OPS™ provides a dynamic simulation and a personalized solution in a simple, quick and accurate way. This gives the surgeon the information required to tailor each surgery for each patient.
