With the implant attached to the femur, the FEA and ASD demonstrated that the femur carried 90% and 93% respectively of the force of walking. Without the implant, the FEA model and ASD femur carried only 35% and 77%, respectively, of the force of walking. Statistical calculations reveal three (3) degrees of separation (99% probability of non-random significant difference) between with and without implant data points. FEA modeling demonstrates that the normal contact forces and shear forces are pushed the distal weight-bearing area of the amputee stump, relieving the lateral stump of frictional forces. The ASD mechanical and FEA modeling data validate each other with both systems supporting the hypotheses with confidence intervals of three degrees of separation between with implant and without implant models.<\/jats:p>","DOI":"10.1093\/milmed\/usy382","type":"journal-article","created":{"date-parts":[[2019,3,22]],"date-time":"2019-03-22T12:11:55Z","timestamp":1553256715000},"page":"627-636","source":"Crossref","is-referenced-by-count":11,"title":["Mechanical and Finite Element Analysis of an Innovative Orthopedic Implant Designed to Increase the Weight Carrying Ability of the Femur and Reduce Frictional Forces on an Amputee\u2019s Stump"],"prefix":"10.1093","volume":"184","author":[{"given":"Tejas P","family":"Chillale","sequence":"first","affiliation":[{"name":"Department of Mechanical & Aerospace Engineering, 231 MAE-A, P.O.
