Abstract

The invention discloses a testing method for lumbar vertebra stretching and buckling angles. The stretching and retracting angles comprise a stretching-position stretching angle alpha1 and a buckling-position buckling angle alpha2, an included angle between a plane built by upper portions of the mesosternum and the sacrum of a testee and a perpendicular plane is the stretching-position stretching angle alpha1, an included angle between a plane built by upper portions of a symphysis pubis position and shoulder blades on two sides of the testee and a perpendicular plane is the buckling-position buckling angle alpha2, a horizontal measuring device and a perpendicular measuring device are fixed or shifted to measure the alpha1 and the alpha2 of the testee. The invention further discloses application of the testing method in lumbar vertebra functional-position radiography. The functional positions of the lumbar vertebrae of patients can be determined by adjusting the horizontal measuring device and the perpendicular measuring device according to lumbar vertebra stretching and buckling angle values of different individual patients, subjective randomness of the patients when the lumbar vertebra functional positions are fixed is reduced, and the radiographic quality of the lumbar vertebra functional positions is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a method for testing the extension and flexion angle of the lumbar spine, and also relates to the application of the method in filming at the functional position of the lumbar spine. Background technique [0002] Diseases such as chronic low back pain, disc herniation, spinal deformity, and spondylolisthesis are related to body position and posture. Patients with low back pain or low back disease often have changes in the physiological curvature of the lumbar spine. Clinically, there are many methods for lumbar spine X-ray examination. Most of them use the lying position (non-physiological load-bearing state) examination method, and only the X-ray examination in the functional position (standing hyperextension position, hyperflexion position) can reflect the patient's lumbar curvature, spondylolisthesis and lumbar disease. In order to provide an objective and ...
