WebJul 1, 2024 · If diaphyseal fixation is attempted using a tapered fluted stem, its stability will be determined by the quality of the reduction and stabilization of the proximal fragments. … WebThe short metaphyseal rTSA design without a diaphyseal stem shows encouraging short- to midterm results, with excellent pain relief and shoulder function, restoration of good active range of motion, and high patient satisfaction scores. The design of this implant seems to result in improved rotation …
WebDespite our finding that metaphyseal cones may help reduce the risk of implant-cement debonding and allow using shorter stems with comparable biomechanical behavior to longer stems, either cones or cement alone can provide comparable results in contained metaphyseal defects.
WebPress-fit stems that engage the diaphysis with cement restricted to the metaphysis constitutes one fixation technique. These long stems restrict coronal alignment of the prosthesis and as a result reduce the likelihood of extreme malposition. how does poison oak spreadWebA choice of distal stem options address fixation and stability while proximal body geometries allow for adjustments to anteversion, height and offset.
