Total knee joint image processing method and device

Abstract

An embodiment of the present invention provides a method and device for image processing of a total knee joint. The method includes: acquiring an X-ray image of the knee joint, and determining the real size of the X-ray image of the knee joint; Input the image to the neural network recognition model for identification, determine key points and key axes; determine femoral size parameters and tibial size parameters based on key points and key axes; determine the type of femoral prosthesis and tibial prosthesis based on femoral size parameters and tibial size parameters and model; determining the placement position and placement angle corresponding to the femoral prosthesis and the tibial prosthesis based on the key axis, the type and model of the femoral prosthesis, and the type and model of the tibial prosthesis. It can be seen that the embodiment of the present invention can save costs, avoid the randomness of manual measurement, and provide an important reference for the calculation of various parameters and the placement of prostheses, thereby reducing the dependence on surgeons.

Description

technical field [0001] The invention relates to the field of artificial intelligence medical technology, in particular to a method and device for image processing of a total knee joint. Background technique [0002] Total knee arthroplasty (Total Knee Arthroplasty, TKA) is an effective method for the treatment of severe knee osteoarthritis and other diseases, and is an essential item in the treatment of knee osteoarthritis. Accurate prosthesis matching is considered to be one of the important factors to reduce complications such as postoperative knee pain, prosthetic loosening, prosthetic wear, and postoperative bleeding, ensure good joint function, and improve postoperative satisfaction. Excessive prosthesis size may lead to poor contact between the prosthesis and the osteotomy surface, resulting in prosthesis loosening, too small a flexion gap, resulting in limited flexion, excessive pressure on the patellofemoral joint, and affecting the function of the knee extensor devi...

AI Technical Summary

Problems solved by technology

It can be seen that in traditional knee arthroplasty, the selection of lower extremity alignment, osteotomy amount, and prosthesis size still depends on the simple radiographs of the radiology department and the experience of the surgeon. may affect the outcome of surgery
