Abstract
A system and method to identify, convey, and reduce the risk of hip dislocations following hip replacement surgery. Preoperative images are used to identify the pelvic tilt of a patient while the patient is in a sitting position, a standing position, and a supine position. Based on the pelvic tilt and pelvic mobility depicted in the preoperative images, the system can identify a quantitative and/or qualitative risk of hip dislocation when the patient is seated, standing, and lying. During surgery, an intraoperative image can confirm the acetabular cup orientation once implanted and the system can determine the risk of hip dislocation when patient is in the supine position. The system can also extrapolate the dislocation risk when the patient is seated and standing based on acetabular cup position and orientation depicted in the intraoperative image.
