쇄골 골절 부위에 따른 축사방향 촬영 최적화 연구

Abstract

Treatment of clavicle fractures requires more precise imaging for accurate diagnosisand treatment, depending on the tendency to change from conservative to surgical treatment. Inaddition, an accurate examination method considering the sigmoidal anatomy and distortion of theclavicle is needed. Therefore, the clavicle study was taken separately before and AP, PA, Oblique,and axial projection. The purpose of the present invention is to provide an accurate imagingmethod according to the fracture pattern by verifying an examination method simultaneously axialimages in a patient̓s oblique position. Sixteen models of Robison clavicle fracture classificationwere made using a 3D printer. In the experimental method, an image was obtained by providing anangle of incidence toward the head from 0~30° in units of 10°. Images were acquired from 0 to 30°in 10° increments toward the head of each rotation angle at 10, 20, 30 and 40° rotational angles. Inthe image evaluation, each radiotechnologist who had more than 10 years of experience evaluatedeach image three times. Evaluation items are 1) Can you accurately assess the alignment? 2) Arethe descriptions of shortening and clavicle fractures well represented? Was evaluated on a 5-pointscale. The patient̓s posture provided an angle of incidence at the oblique position, which waseffective in aligning, shortening, and fracture shape of the midshaft and lateral fractures of theclavicle. The midhaft fracture was especially effective for simple and multigragmnetary fractures. Axio-oblique projection of clavicle fractures is an effective test.
