Overview

Case report reveals improved short-term function and range of motion following cementless allograft-prosthetic composite reverse shoulder arthroplasty for proximal humerus nonunion, highlighting...

Key Points

  • Evaluate the clinical feasibility of a cementless allograft-prosthetic composite reconstruction using an interlocking revision stem for salvage reverse total shoulder arthroplasty in proximal humerus fracture nonunion.
  • Performed a salvage reverse total shoulder arthroplasty with allograft-prosthetic composite reconstruction on a 55-year-old male presenting with a proximal humerus fracture nonunion (N=1).
  • Utilized a long revision stem with interlocking screws to restore anatomical length and rotation without requiring bone cement.
  • The reconstruction achieved significant qualitative improvements in shoulder range of motion and overall functional ability at the six-week postoperative follow-up.
  • The patient was lost to follow-up after the six-week postoperative visit, preventing long-term structural and functional evaluation.
