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
The invention belongs to technical field of medical instruments, be specifically related to the method for testing that a kind of lumbar vertebra stretches angle in the wrong, the invention still further relates to the application of the method in the film making of lumbar function position.
Background technology
The diseases such as chronic low back pain, intervertebral disk hernia, deformity of spine and spondylolysis are relevant with position and posture, often there is the change of lumbar physiological-curvature in the patient of lumbago and skelalgia or waist lower limb disease, method great majority clinically for lumbar X ray examination adopt clinostatism (under non-physiology loading conditions) inspection technique, and the x-ray inspection only under functional position (hyperextension position of standing, cross bend position) situation could reflect the truth of patient's lumbar curvature, centrum olisthe degree and lumbal vertebra, thus provide objective and accurate foundation for the selection of Therapeutic Method.Another application for a patent for invention " a kind of gesture rack for the film making of lumbar function position " (publication number 102631214A) of the present inventor discloses a kind of gesture rack for the film making of lumbar function position, patient is edge-on between left and right adjusting rod, fix the hyperextension position of health by the up-down adjustment of left and right adjusting rod and cross position in the wrong, solving the problem affecting shooting quality time film making in lumbar function position because health moves.
In order to accurately reflect patient's lumbar curvature, the truth of centrum olisthe degree and lumbal vertebra, when carrying out the film making of lumbar function position, require that patient is with hyperextension to greatest extent and excessively in the wrong, due to this hyperextension to greatest extent and excessively bend decide with subjective sensation, simultaneously, the height of human body, lumbar vertebra length, there is obvious difference along with the difference of individuality in healths etc., what lumbar vertebra was excessive stretches or bends the damage that can cause patient, lumbar vertebra can affect again the quality of film making when stretching or bend inadequate, therefore, this with subjective sensation to greatest extent hyperextension and excessively bending determine that the method for functional position (stand hyperextension position and stood bend position) is random large, lack scientific and objectivity.
Summary of the invention
The technical problem to be solved in the present invention is to provide the method for testing that a kind of lumbar vertebra stretches angle in the wrong, the method can easily and accurately test person upper body stretch angle in the wrong.
Another object of the present invention is to the application that this method of testing is provided, this method of testing can overcome existing patient's functional position when making film for lumbar function position can not the deficiency of objective and accurate control, for time film making in lumbar function position, the degree in the wrong of stretching of lumbar vertebra provides normalizing operation mode, thus the individual variation accurately between the different patient of reflection.
For solving the problems of the technologies described above, a kind of lumbar vertebra of the present invention stretches the method for testing of angle in the wrong, described in stretch angle in the wrong comprise stretch position stretch angle [alpha]
