Morphological recognition and visualization method for tendon-bone joint part of knee joint posterior-lateral complex

Abstract

The invention discloses a form recognition and visualization method for a tendon-bone joint part of a knee joint posterior-lateral complex. The method comprises the following steps that firstly, a cross-section thin-layer true-color high-resolution image of a rear outer side structure of a human knee joint is recognized and segmented; on the basis, three-dimensional reconstruction based on surfacedrawing is carried out on the knee joint rear outer side complex and the adjacent structure thereof; then the thighbone, the tibia and the fibula of the knee joint and the three-dimensional images reconstructed by the FCL, the PT, the PFL and the BT of the PLC are exported in the form of triangular grids; all contact surfaces of the FCL, PT, PFL and BT are marked with the tendon-bone joint partsof the femur and fibula respectively; the tendon-bone joint parts and the central points of the anatomical structures on the femur and the fibula are obtained, the areas of the tendon-bone joint partsof the anatomical structures and the mutual distances between the central points of the tendon-bone joint parts of the anatomical structures are measured, finally, an interactive 3d-pdf model is created for visualization, and the problem that the attachment parts of the tendon-bone joint parts are difficult to determine and observe is solved.

Description

technical field [0001] The invention belongs to the research field of the posterolateral side of the human knee joint, and relates to a form recognition and visualization method of the tendon-bone junction of the posterolateral complex of the human knee joint. Background technique [0002] The posterolateral complex (PLC) is a complex anatomical and functional complex located in the posterolateral area of ​​the knee. PLC is composed of multiple tendons and ligaments. According to the previous research on the Chinese visualized human data set, PLC is mainly composed of peroneal collateral ligament (FCL), popliteus tendon (PT), popliteal peroneal ligament (PFL), biceps femoris tendon (BT) ), the arcuate ligament (APL) and the fecal ligament (FFL), which together maintain the static and dynamic stability of the PLC of the knee joint. and external rotation. [0003] Injuries to the PLC occur in nearly 16% of all knee injuries, and if not properly recognized and diagnosed, thes...
