Embodiment 1

[0097] The overall flowchart of embodiment can refer to figure 1 Shown:

[0098] 1. Zoom in on the hips, knees and ankles

[0099] Partially enlarge the three target parts of the hip joint, knee joint and ankle joint in the full-length weight-bearing X-Ray image of the lower limb. The enlarged hip part completely shows the femoral head, the knee part shows the distal femur and tibial plateau completely, and the ankle part shows the talus completely.

[0100] 2. Calculate and obtain several key points

[0101] (1) Center point of femoral head:

[0102] Use three points (P 1 , P 2 , P 3 ) to fit a circle, and manually adjust the positions of the three points to make the fitting circle consistent with the size and position of the femoral head. At this time, the center of the circle is the center of the femoral head (H 0 ), for details, please refer to figure 2 shown.

[0103] If P 1 (x 1 ,y 1 ), P 2 (x 2 ,y 2 ), P 3 (x 3 ,y 3 ), the equation of a circle fitted ...

Abstract

The present invention relates to the field of clinical medicine, and in particular to a system, a computer readable storage medium and an apparatus that can be used for two-dimensional planning of high tibial osteotomy. The present invention provides a computer readable storage medium storing a computer program, the computer program is executable to implement method steps, and the method steps comprise: acquiring a lower-limb full-length weight-bearing-position bone fluoroscopic image; acquiring a force line position; acquiring a lateral angle of the distal femur; acquiring a medial angle of the proximal tibia; acquiring an osteotomy angle [theta], and acquiring the position of the postoperative force line and/or the postoperative medial angle of the proximal tibia according to the osteotomy angle [theta]. The method provided by the invention can flexibly select the target position of the postoperative force line according to different lower limb conditions of different patients, so that the planning is more individualized.

Description

technical field [0001] The invention relates to the field of clinical medicine, in particular to a system, a computer-readable storage medium and equipment for two-dimensional planning of high tibial osteotomy. Background technique [0002] High tibial osteotomy is mainly used to treat medial knee osteoarthritis. The core of this operation is to reduce the wear on the medial side of the knee joint through osteotomy and adjust the force line of the lower limbs that deviates to the medial side of the knee joint (the line connecting the center of the femoral head at the weight-bearing position and the center of the ankle joint). Therefore, the main purpose of the operation is to make the patient’s After the operation, the lower limbs get a suitable line of force. [0003] The traditional two-dimensional planning of surgery is to set a recognized and suitable postoperative force line target position, that is, the force line passes through the Fujisawa point of the knee joint (a...
