Stress shielding in reverse shoulder arthroplasty using a proximally coated stem for proximal humeral fractures: Does it have clinical relevance?

Objectives: To evaluate the clinical significance of stress shielding in patients who have undergone an uncemented reverse shoulder arthroplasty (RSA) with a proximally coated stem for complex proximal humeral fractures (PHF) comprising 3 or 4 parts, assessed at 2 years postoperatively. Additionally, this study aims to examine the correlation between tuberosity healing and clinical outcomes.

Methods: Single Centre.
