Analysis on stress and micromotion on various PEG fixation at glenoid implant

Six commercially available implant designs were simulated via finite element analysis. The objectives of this study are (1) to determine the effect of peg numbers and orientations to the stress distribution at the implant and cement (2) to compare the micromotion between fully cemented and partially...
