Personalized Hip Replacement Technology
OPS™ grew from close collaboration between clinicians and engineers who attempted to address 2 major issues in total hip replacement - Firstly, what is the target for a well orientated component? And, secondly, how do we deliver that target intra-operatively?
UNIQUE PROPERTIES / PROJECT DESCRIPTION:
The OPS™ technology platform allows total hip replacement to be customized for each patient. This is achieved by better understanding the movement profile of each patient, thereby allowing implant selection and orientation to be optimized based on a series of unique and dynamic input data.
OPERATION / FLOW / INTERACTION:
OPS™ technology enables the surgeon to understand the individual pelvic motion profile of each patient before their surgery. This is driven by simple imaging protocol which generates key input data that feeds into the computation modelling package. Multiple simulations can then be produced to highlight the unique way in which patient’s perform their normal everyday activities. From here, the surgeon is provided with an accurate laser guided alignment system which allows the customised implant orientation to be reliably achieved during surgery.
PROJECT DURATION AND LOCATION:
The project commenced in 2010 as a small start up (called Optimized Ortho) with a commercialization grant from the Australian Government. In 2014, Optimized Ortho was purchased by a British orthopaedic company named Corin.
FITS BEST INTO CATEGORY:
Scientific Instruments, Medical Devices and Research Equipment Design
PRODUCTION / REALIZATION TECHNOLOGY:
A key community of early users provided a window to more closely understand and observe the usability of the technology and the constraints encountered in real world scenarios. This allowed us to visualise, evaluate and rapidly refine iterations of the product early and often in the design process, therefore leveraging the value of immediate information and avoiding more costly mistakes later in the design pathway
SPECIFICATIONS / TECHNICAL PROPERTIES:
The process begins with medical imaging (CT and X-ray) to define the patient specific geometry and functional movement parameters. Dynamic simulation software is then used to optimize the orientation of the components to be utilized in theatre. Following this 3D printed customized surgical guides are printed and sterilized for use in the operating room that will ultimately aid in delivering the optimized orientation.
OPS™, OPS™ hip replacement, Optimized Positioning System, OPS™ Functional hip replacement, Optimized hip replacement
We have now collected functional imaging on over 2500 patients worldwide providing us with a world leading database on patient specific functional positioning and its impact on component positioning in total hip replacement. We are now able to utilize this information in increasingly effective ways to optimize surgical outcomes.
The major challenge came from turning a fantastic idea into a commercial reality. This involved ensuring that business partners were appropriate and the internal staff selected to launch and support the technology were high caliber individuals.
