Dislocation of reverse shoulder arthroplasty with polyethylene liner dissociation requires open reduction. Radiographic clues, such as a subluxation appearance, help differentiate this from standard dislocations.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Radiology

Background:

  • Reverse shoulder arthroplasty (RSA) is a common orthopedic procedure.
  • Dislocation is a known complication of RSA.
  • Polyethylene liner dissociation from the humeral tray is a rare but serious complication.
