Femoral Bone Gain and Loss Analysis after Total Hip Arthroplasty

Abstract

Total hip arthroplasty (THA) has completely revolutionized treatment of the arthritic hip and is widely considered to be one of the most successful modern orthapaedic interventions. Developed as a solution for extreme joint pain, THA is now being performed on well over 300,000 patients annually in the United States alone, alongside a near-exponential projected increase in utilization currently being observed worldwide [1]. THA prosthesis fixation is performed using two distinct methodologies: with or without the use of bone cement. Deciding which method is optimal for a given patient is typically based upon generally qualitive factors, such as age and gender, rather than with a standardized quantitative assessment modality. As part of a multimetric study aiming to implicate potential quantitative metrics for pre- and post-operative THA assessment, we present the folowing study on the gain and loss of fermoral bone in THA patients. This investigaton demonstrates the utility of the reported methods for quantitative patient-specific assessment.
