Custom Bi-flanged Constrained Total Shoulder Revision Implants: A Novel Design and Report of Two Cases

Abstract

Custom revision total shoulder replacements are one option for salvage of failed shoulder arthroplasty, but reports are scarce. We report two cases of revision shoulder arthroplasty using a custom constrained total shoulder (CCTS) endoprosthesis with a bi-flanged scapular (BFS) component in the setting of soft tissue, humeral, and glenoid bone loss. The CCTS with BFS is a viable salvage implant for failed reverse total shoulder arthroplasty to achieve pain reduction, but long-term follow up is needed.
