Internal strain distribution of the human femur under compressive loading measured by digital volume correlation
Abstract
Understanding the mechanism of osteoporotic femoral neck fracturesisimportantforimprovingdiagnosisandtreatmentsofosteoporosis.Standardmechanicaltestingcanmeasurethefemoralstiffnessandstrengthunderdifferentloading scenarios. However, it does not provide information about internal deformations and location of fracture onset. A combinationoftime-elapsedmicro-CTimaging,step-wiseloadingandDigitalVolumeCorrelation(DVC)hasbeenalreadyusedformeasuringdeformationwithintrabecularbonespecimens[1]andvertebralbodies[2]butitsapplicationtoimagesofspecimensasbigastheproximalhumanfemurischallenging.Thegoalofthisstudyistodevelopaprotocoltomeasurethefull3Dfielddistributionofstrain,fromtheelasticrangeuptofailure,intheentirehuman proximal femur.
