Corin OPS™

Optimized Positioning System

Every patient moves differently and a total hip replacement should be optimized to account for this.

Research has demonstrated that the pelvis rotates extensively in the sagittal plane. These pelvic rotations are patient specific, and change the functional orientation of the acetabulum during different activities of daily living.

Historically, optimal cup orientation has been defined by generalised  '˜safe zones' advocating 35 to 45 degrees of inclination and 5 to 25 degrees of anteversion. Further to this, there is currently no consensus in the literature as to what reference frame to use when making these measurements.

Complications associated with malorientation of the acetabular component are widely published:

  • Increased dislocation rate
  • Component impingement
  • Edge loading
  • Squeaking
  • Accelerated bearing surface wear
  • Osteolysis and loosening.

Corin Optimized Positioning System, OPS™, consists of two parts:

  • Step 1: a dynamic, functional and pre-operative simulation
  • Step 2: a patient-specific delivery system

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.
