A Pose-Correction Method for Intraoperative Measurements in Total Hip Surgery

During hip replacement surgery, current x-ray-based methods for guiding implant placement are often
affected by differences in patient positioning on the surgical table and movements of the hip joints, leading
to inconsistent and unreliable assessments. This research addresses part of these challenges using
advanced computer simulations to explore how various factors influence the accuracy of x-ray-based
measurements during hip replacement surgery. By developing improved techniques to create 3D models
of bones and implants from multiple x-rays taken at different angles during surgery, we aim to provide more
precise and reliable measurements to surgeon during operation. These “adjusted” measurements will
account for movements of pelvis and hip joint positions during surgery. The methods will be tested using
data from 100 simulated surgeries and compared with highly accurate 3D scans. The ultimate goal is to
integrate these advancements into existing assistive technologies, improving surgical outcomes and
reducing the risk of errors.
