Cemented stem implantation: Finite element simulation vs. clinical bone densitometry
J Arthroplasty. 2014 Jan;29(1):90-100. doi: 10.1016/j.arth.2013.03.028.64 patients scheduled to undergo total hip arthroplasty were randomized to receive either a VerSys or ABG-II cemented femoral stem. Bone mineral density was monitored over a 5 year follow-up period and a finite element (FE) simulation was run concurrently, modelling stem mechanical behavior and measuring the biomechanical variations. At 5 years postoperatively, correlations between clinical results and FE simulation models were found in several GRUEN zones, suggestive of biomechanical influences in the adaptive bone remodeling process. Additionally, bone growth was seen to progressively increase during the entire study period. Nonetheless, this area of research warrants further studies.
