Mid-term results with an anatomic stemless shoulder prosthesis in patients with primary osteoarthritis

The introduction of a stemless prosthesis in shoulder arthroplasty represents a novel design whereby the proximal humerus is restored anatomically, while leaving the diaphysis of the humerus untouched. The aim of this study was to present the mid-term results of total evolutive shoulder system (TESS; Biomet？), a stemless shoulder prosthesis
