摘要: Products from fretting wear and corrosion in the taper junction of total hip arthroplasty (THA) devices can lead to adverse local tissue reactions. Predicting damage as a function design parameters would aid development more robust devices. The objectives this study were develop an automated method for identifying areas on THA junctions, assess predictive ability finite element model simulate junctions. constructs fatigue loaded, thus inducing stem taper. An imaging analysis algorithm quantified surfaces. Specimen-specific models used calculate work done (FWD) at junction. Simulated FWD was correlated imaged wear. Results showed that approach identified surface. Additionally, greatest tapers exhibiting distal contact. Finite predicted average 30.3% With additional validation, techniques may be useful manufacturers regulators review new
