Computational And Experimental Biomechanics Of Total Hip Wear Increase Due To Femoral Head Damage, Karen Marie Kruger

Theses and Dissertations

Aseptic loosening due to wear-induced osteolysis remains a leading cause of failure in total hip arthroplasty (THA), particularly in revision cases beyond the second decade of use. Historically, there have been large amounts of variability of wear within individual THA patient cohorts. Evidence indicates that femoral head damage can be a cause of this variability. While femoral head damage as a result of third body particles and subluxation and dislocation events has been well documented, direct quantifiable linkage between femoral head damage and wear acceleration remains to be established. Due to large ranges of observed retrieval damage, wear testing protocols ...
