Augmented reality significantly reduces the absolute error between achieved and planned inclination and version of the glenoid baseplate for reversed shoulder arthroplasty.

ABSTRACT:

Background

To determine whether using augmented reality with a head-mounted display (AR-HMD) would reduce deviations between planned and achieved reverse total shoulder arthroplasty (rTSA) glenoid baseplate inclination and version.

Methods

Ten fresh frozen shoulders from 5 human cadavers, which were free from fractures or other bony pathologies were used. Computed tomography scans were acquired for each shoulder, and imported into image 3-dimensional processing software to plan rTSA, and notably to define the target inclination and version of the glenoid baseplate. Two experienced surgeons placed a 1.6-mm Kirschner wire on the glenoid baseplate insertion site in each shoulder (5 per surgeon) using conventional instruments, and the AR-HMD was used to measure the inclination,
