# Novel Custom 3D-Printed Glenoid in Reverse Total Shoulder Arthroplasty: A Case Report of Bilateral Total Shoulder Arthroplasties

## TL;DR

A patient had successful shoulder surgeries using a custom 3D-printed implant, showing promising results for complex cases.

## Contribution

A novel use of a 3D-printed custom glenoid implant in reverse total shoulder arthroplasty is presented.

## Key findings

- Functional results at one year were comparable between shoulders with and without a custom implant.
- Custom glenoid implants show promising clinical and radiological outcomes in complex cases.

## Abstract

Glenoid bone loss in the setting of complex reverse total shoulder arthroplasty (rTSA) poses a challenge to surgeons. The advent of custom-made glenoid implants has allowed for the restoration of glenoid alignment and version in cases of significant defects. We present a novel case of a patient who underwent bilateral rTSAs, one of which was performed with a 3D-printed custom glenoid implant. Functional results at one year were comparable between the two shoulders, despite the significant preoperative glenoid defect in the shoulder that required a custom component. This case report and other early results with custom glenoid augments demonstrate promising clinical and radiological outcomes.
