Dear CSS Members and Colleagues:
Enclosed is a presentation from Mark Frankle specifically addressing his opinion regarding the Biomechanics presentation on vumedi by Zumstein. I had posted this link previously. Please take note that this is, as usual, very thoughtful in blending biomechanics as well as clinical outcomes; though it is promotional for a particular product. Be advised, many other systems take advantage of these biomechanical observations and recent analysis using IMASCAP (now marketed as Blueprint) have confirmed optimal geometry and mechanics for reverse prosthesis.
