Real-Time Estimation of Hip Range of Motion for Total Hip Replacement Surgery

Abstract

Abstract. This paper presents the design and implementation of a range of motion estimation method that is capable of fine-grained estimation during total hip replacement (THR) surgery. Our method combines an adaptive refinement strategy with a high performance computing system in order to enable real-time estimation. The experimental results indicate that the implementation on a cluster of 64 PCs enables intraoperative estimation of 360 × 360 × 180 stance configurations within a half minute, and thereby plays a key role in selecting and aligning the optimal combination of artificial joint components during THR surgery.

“…Hip ROM also plays an important role for evaluating the surgical outcome of total hip replacement (THR). Kawasaki et al 26 used an adaptive refinement strategy and Sun et al 27 used a computed tomography (CT) image based 3D geometric method to simulate hip ROM for THR, respectively.…”

“…Some impingement detection methods mentioned above26, 28–31 were primarily focused on improving the performance by taking advantage of the ball‐and‐socket model for hip anatomy. Therefore, these methods might not be ideal for non‐ball‐and‐socket models such as knee, spine, and wrist at the same time as computation efficiency enhanced.…”
