Elliptical and spherical heads show similar obligate glenohumeral translation during axial rotation in total shoulder arthroplasty
BackgroundElliptical shape humeral head prostheses have been recently proposed to reflect a more anatomic shoulder replacement. However, its effect...

15-year survivorship of a unique dual-modular femoral stem in primary hip arthroplasty
BackgroundHip offset, version, and length are interdependent femoral variables which determine stability and leg length. Balancing these competing...
