Polyethylene wear is a key factor affecting the lifespan of orthopedic prostheses. <\/span>Univ.-Prof. Dr. med. Marcus J\u00e4ger, Chair of Orthopedics at the <\/span>Marienhospital<\/span> at the University of Duisburg-Essen, uses RAYLYTIC\u2019s <\/span>RayMatch<\/span> method to automatically and noninvasively measure prosthetic wear in total hip arthroplasties (THA) with remarkable precision.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Measuring polyethylene wear in THA in clinical trials<\/b><\/h4>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

In Dr. J\u00e4ger\u2019s research, every micrometer counts. As part of the \u201cVITAS” study initiated by Aesculap AG, which is exploring how acetabular liner material in THA affects wear, Dr. J\u00e4ger required a highly precise method for quantifying wear behavior and cup positioning. <\/span>\u00a0<\/span><\/p>

These two factors are linked to the production of microparticulate debris\u2013a central factor in aseptic loosening of prosthetic joints. Aseptic loosening can cause severe complications for patients, necessitating corrective surgeries or even leading to total failure of the prosthesis.\u00a0<\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Automated polythylene wear analysis and automatic determination of cup anteversion and inclination in total hip arthroplasty (THA)<\/b><\/h4>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

RAYLYTIC\u2019s RayMatch method represented a scientifically validated, minimally invasive way for J\u00e4ger to observe wear behavior in hip prostheses. After uploading imaging data from his hospital\u2019s PACS (picture archiving and communication system) directly and in compliance with data protection standards to RAYLYTIC\u2019s cloud-based platform, he could rely on \u201cautomated processes that cannot be influenced by researchers\u201d to ensure his results were free from bias down to the finest detail.\u00a0<\/span>\u00a0<\/span><\/p>

With this precision, J\u00e4ger is aiding in the development of biomaterials which result in lower levels of wear and better implant performance.\u00a0<\/span>\u00a0<\/span><\/p>

J\u00e4ger also emphasized how RAYLYTIC\u2019s subject-specific expertise and approachability allow him to swiftly resolve challenges as they arose, saving him and his team time.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

RayMatch\u2019s edge over conventional X-ray analysis techniques in the analysis of polyethylene wear<\/b><\/h4>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The RayMatch method utilizes CAD data of the implant components provided by the manufacturer to automatically determine the position and orientation (anteversion and inclination) of the prosthesis with the help of artificial intelligence. In this case, anteroposterior pelvic radiographs were analyzed one and five years post-operatively for femoral head penetration and cup positioning.\u00b9<\/em><\/span>\u00a0<\/span><\/p>

Other methods proved to be too unreliable for J\u00e4ger because of their subjective measurement procedures. He stressed that software programs that volumetrically determine wear rates result in too much variance, especially when multiple users evaluate the medical imaging data. <\/span><\/p>

Other methods require that anatomical landmarks are manually placed by radiologists. \u201cThese procedures are too error-prone,\u201d said J\u00e4ger. X-ray projection of the images depends heavily on the positioning of the patient, which can negatively influence the subjective placement of anatomical markers. In addition to being unreliable, measuring wear volumetrically with a vector solution requires additional invasive procedures.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
