Influence of uncemented humeral stem proximal geometry on stress distributions and torsional stability following total shoulder arthroplasty

Influence of uncemented humeral stem proximal geometry on stress distributions and torsional stability following total shoulder arthroplasty

Abstract Background While surgeons tend to implant larger stems to improve torsional stability, numerous studies demonstrated that increasing humeral stem diameter could exacerbate stress-shielding and lead to bone resorption. We aimed to determine the influence of humeral stem proximal geometry on...
