Automated femoral landmark extraction for optimal prosthesis placement in total hip arthroplasty

摘要: The automated extraction of anatomical reference landmarks in the femoral volume may improve speed, precision, and accuracy surgical procedures, such as total hip arthroplasty. These are often hard to achieve, even via incision. In addition, it provides a presurgical guidance for prosthesis sizing placement. This study presents an workflow orientation landmark from 3D surface mesh. parameters neck axis, middle diaphysis both trochanters center head will allow surgeon establish correct position bony cuts restore leg length offset. definition medullary canal endosteal wall is used prosthesis' stem. Furthermore, alignment methods were implemented provide with information about performance each patient-specific femur-implant couplings. considers different commercially available stems has potential help preoperative planning arthroplasty accurate, repeatable, reliable way. positional errors significantly reduced, therefore, risk implant failure subsequent revision surgery also reduced.
