Abstract
ABSTRACT Objective: To compare the measurement of the Cobb angle in printed radiographs and digitalized radiographs displayed with the "PixViewer" tool. Methods: Pre-operative radiographs of 23 patients were performed in printed films and using the software "PixViewer". The same evaluator, a spine surgeon, chose the proximal and distal end vertebrae at the limit of the main curve in printed radiographs without identifying patients, and measured the Cobb angle based on these parameters. The same parameters and measurements were performed in digitalized radiographs. The measurements were compared, as well as the choice of end vertebrae. Results: The average change in the Cobb angle between the methods was 1.48±1.73°. The intraclass correlation coefficient (ICC) was 0.99, demonstrating excellent reproducibility. Conclusion: The Cobb method can be used to evaluate scoliosis through the "PixViewer" tool with the same reliability of the classic method on printed radiographs.
Highlights
Gunshot wounds are lesions of a blunt nature caused by bullets or projectiles fired from a gun and from concurrent elements plus neo-elements formed at the time of the shooting
Due to the social and security situation in our country over the last four years, spinal injuries from firearm projectiles are relatively frequent among the military population. These are associated with a high level of short, mid, and long-term sequelae, great physical disability, prolonged hospitalization time, generating very high costs. It is for this reason that in our hospital a particular interest has been generated in converting it into a production and scientific medical information center focused on gunshot wounds to the spine and war surgery at the national and international levels
The tissue damage that occurs in gunshot wounds is a result of the consecutive effect of the projectile and the cavitation correlated with the kinetic energy
Summary
Gunshot wounds are lesions of a blunt nature caused by bullets or projectiles fired from a gun and from concurrent elements plus neo-elements formed at the time of the shooting. Firearms are defined as instruments in various forms intended to launch projectiles using the forces of gases released when the gunpowder is ignited. Each year in the United States of North America, approximately 30,000 to 50,000 people die from causes secondary to gunshot wounds, the greatest number of deaths occurring in the 1 to 19 years of age group. It is estimated that for each death there are at least three disabling wounds. This translates to approximately 150,000 gunshot wounds per year.[1] In the same country, violence with firearms, regardless of the medical implications, has a high
