I. Overview X-ray is one of the important examination means of clinical orthopedics (orthopedics), its effect is to check whether there are real (instrumental) lesions in bone (spine), joints, etc., to confirm or verify whether the preliminary clinical diagnosis is correct, to clarify the location, nature, quantity, size, degree of lesions and the relationship with the surrounding soft tissues, to provide reference for treatment, to provide a reliable basis for treatment measures, to provide a valuable prognosis It is also the basis for judging the effect of treatment (especially for fracture, dislocation, alignment and alignment observation after rectification, etc.). 1. Now we will only talk about X-ray plain films, which have great practical value in the plain films of the spine! X-rays are the most common means of diagnosing spine-related diseases, and are also the basis for the treatment of such diseases, for this reason, we must be able to see the film ourselves, and see accurately, can not rely solely on the radiologist’s X-ray report to do clinical treatment, because they do not understand the patient’s condition, only the general description and diagnosis according to the routine, so we can only be used for reference, for our Orthopedic injury (orthopedics) clinicians, reading a good X-ray film, is both a good basis for diagnosis, but also the first-hand information of treatment! And to describe the actual situation according to the X-ray film image, truthfully recorded in the medical record. 2, look at the film, divided into macroscopic and microscopic, first macroscopic is to look at the X-ray film, is to look at the intergranular situation of the bone, to compare up and down, left and right, that is, the scope of the bone, shape, size, structure, joint (surface, cavity and cavity of the circumferential bone situation), and then focus on observing the lesion site! In the case of a review film, comparison with the original film is necessary. In contrast, microscopic observation is appropriate: (1) On X-ray films, the subtlety of the lesion site and its surrounding soft tissues should be carefully observed. (2) CT and RMI are good microscopic views, which should also be observed carefully and slowly.
