Through the research on the prior art, the inventor found that: because the patient is in a pathological situation, it is difficult to judge the difference between the patient's current spinal deformity state and the original anatomical state in the prior art, and it is difficult to find out from the spine-pelvic pathological changes. How much is pathological changes, how much is functional compensation, and thus cannot better guide scoliosis surgery

Embodiment 1
[0055] figure 1 It is a schematic flowchart of a spine digital reconstruction method provided in the embodiment of the present application.
[0056] like figure 1 As shown, the method provided in the embodiment of the present application includes the following steps:
[0057] S100: Detect the pelvic projection angle of the person to be detected.
[0058] As a parameter of pelvic anatomy, the pelvic projection angle varies among individuals. It maintains a relatively constant value after the growth of human bones stops, and does not change with changes in body position. In recent years, studies have shown that the value of the pelvic projection angle has a slight increase trend with the growth of the human body, and reaches a stable state after growth stagnation in adulthood.
[0059] In the embodiment of this application, as figure 2 As shown, this step can include:
[0060] S101: Obtain an X-ray film of the person to be detected.
[0061] The detection of X-ray films h...
Embodiment 2
[0091] Figure 6 It is a schematic structural diagram of a spinal reconstruction system provided by the embodiment of the present application.
[0092] like Figure 6 As shown, the system includes: an angle acquisition unit 1, a first determination unit 2 and a model reconstruction unit 3, wherein:
[0093] The angle acquisition unit 1 is used to detect the pelvic projection angle of the person to be detected, and obtains the pelvic inclination angle by looking up a table in the preset correspondence table between the pelvic projection angle and the pelvic inclination angle, and calculates the sacrum according to the pelvic projection angle and the pelvic inclination angle. Tilt angle.
[0094] In the embodiment of this application, as Figure 7 As shown, the angle acquisition unit 1 includes: a pelvic projection angle measurement unit 11 and an angle calculation unit 12, wherein:
[0095] The pelvic projection angle measurement unit 11 is used to measure the pelvic projec...

Abstract
The invention discloses a vertebral column digital reconstruction method and a vertebral column digital reconstruction system. The method comprises the following steps of: detecting a pelvis projection angle of a person to be detected; checking in a preset table of the corresponding relationship between the pelvis projection angle and a pelvis inclination angle so as to obtain the pelvis inclination angle; calculating according to the pelvis projection angle and the pelvis inclination angle so as to obtain a sacrum inclination angle; determining the relative length of a sagittal plane vertebral column of an orthopedic vertebral column fragment after the preset orthopedic; and reconstructing a vertebral column-pelvis sagittal plane balance model according to the determined relative length of the sagittal plane vertebral column and the sacrum inclination angle. According to the method, on the basis of the pelvis projection angle of a patient, the balance of vertebral column-pelvis sagittal plane can be reconstructed through a series of calculation and drawing; and in comparison with the prior art, a stable vertebral column-pelvis sagittal plane can be reconstructed by the method, so that the vertebral column orthopedic operation can be instructed effectively, and the curative effect after the operation is improved.
Description
technical field [0001] The present application relates to the field of digitization technology, in particular to a spine digital reconstruction method and system. Background technique [0002] Adult scoliosis is defined as a spinal deformity with a Cobb angle greater than 10° in the coronal plane in persons over 20 years of age. The coronal shape of the spine shows that one or several segments deviate laterally from the midline of the body to form a deformity with a radian. Usually, the shape of the sagittal plane also has an increase or decrease of kyphosis or lordosis, accompanied by spinal deformities. Rotational deformity is a three-dimensional deformity. Aebi broadly divides adult scoliosis into three categories according to etiology: adult idiopathic scoliosis, adult degenerative scoliosis, and adult secondary scoliosis. [0003] As the population ages, the incidence rate tends to increase. As people's requirements for life are getting higher and higher, patients wi...
