Dataset description

Dual mobility (DM) implants are being increasingly used for total hip arthroplasties due to additional range of motion and joint stability they afford over more traditional implant types. Currently there are no reported methods for monitoring their motions under realistic operating conditions and therefore, it is challenging to predict how they will function under clinically relevant conditions and what failure modes may exist. This repository contains the validation data and required post-processing scripts for a novel inertial tracking system that directly mounts to the mobile liner of DM implants. The tracker was custom built and based on a low-cost, off-the-shelf inertial measurement unit (IMU) and employed a gradient-decent sensor fusion algorithm for amalgamating nine degree-of-freedom IMU readings into three-axis orientation estimates. Additionally, a novel approach to magnetic interference mitigation using a fixed solenoid and magnetic field simulation was evaluated.
