Accurate determination of hip implant wear, cup anteversion and inclination through AI automated 2D‐3D registration

Abstract: The precise and accurate measurement of implant wear, acetabular cup anteversion and inclination from routine anterior‐posterior radiographs still poses a challenge. Current approaches suffer from time‐consuming procedures accompanied by low and observer‐dependent accuracy and precision. We present and validate a novel, automated method for determining total hip arthroplasty parameters by comparing its accuracy and precision with methods in contemporary scientific literature. The algorithm uses CAD‐model‐based… Show more

“…The main limitation of CT-RSA is the higher radiation dose [35]. In addition, artificial intelligence (AI), which is a very useful tool in image analysis [36], is rapidly developing to measure prosthesis migration in both CT [37] and standard clinical radiographs [38]. While there seems to be an increasing role of AI in orthopedic image measurements as well as to analyze these measurements [39][40][41][42], it is increasingly important to unbox the black box of AI so that AI-based conclusions are explainable to doctors and patients [43,44].…”
