Surgical Fixation of Periprosthetic Humerus Fractures Using an Extension Plate: Surgical Technique and Report of 5 Cases

Periprosthetic fractures after shoulder arthroplasty occur in up to 2% of patients. In patients with stable components who fail or cannot undergo nonoperative management, stable fixation is required. We present a new technique to obtain proximal fixation around the humeral component using a 4.5-mm large fragment plate and a 3.5-mm attachment plate.
