Computational comparison of reamed versus unreamed intramedullary tibial nails.

摘要: We compared, via a computational model, the biomechanical performance of reamed versus unreamed intramedullary tibial nails to treat fractures in three different locations: proximal, mid-diaphyseal, and distal. Two finite element models were analyzed for two nail types kinds fractures. Several variables determined: interfragmentary strains fracture site, von Mises stresses bolts, strain distributions tibia fibula. Although good mechanical stabilization was achieved all simulated fractures, best results obtained proximal mid-diaphyseal distal nail. The interlocking general, subjected higher than one; thus former technique is more likely fail due fatigue.
