FEA Analysis of Neck Sparing Versus Conventional Cementless Stem

Finite element analysis is a valuable tool in prosthetic design and helps predict specific mechanical behaviors between mechanical testing and clinical observations1. We have studied the effect of tensile stresses of both conventional length stems with conventional neck resections and compared them to a novel short curved neck sparing tissue preserving stem design and have found correlation between FEA modeling and plain radiographics. Neck sparing stem with a novel conical flair does improve bio-mechanical conditions in THA as compared to conventional length cementless stems.
