Prevalencia de lesiones del manguito de los rotadores diagnosticado por resonancia magnética en el Departamento de Imagenología del Hospital Monte Sinaí, en el periodo enero 2021 – junio 2023

Abstract

Background: Rotator cuff (RC) injuries result from the tearing of one or more tendons. It is a structure comprising four muscles and tendons attached to the shoulder joint. They often become irritated, torn, or worn out. Injuries are the most common cause of pain and functional limitation of the shoulder. Objective: To determine the prevalence of RC injuries diagnosed by magnetic resonance at the imaging department of the Monte Sinaí Hospital in the city of Cuenca, from January 2021 to June 2023. Methodology: Descriptive, retrospective, and crosssectional study. Universe made up of all patients from 21 to 80 years of age who underwent a shoulder MRI. The sample comprised all patients diagnosed with RC lesions, observing inclusion and exclusion criteria. Results: Out of 520 patients studied, 504 (96,92%) reported RC injuries. Based on this analysis, a higher prevalence was found in patients aged 61-70 years (25,40%), while, based on sex, there was a higher prevalence in males, featuring 275 cases (54,56%). Likewise, the type of injury with the highest prevalence was that of category “More than one injury” with 433 (85,91%). Conclusion: The results obtained show similarity in regard to some studies, while others differ from published results of previous research. MRI is the most effective study to diagnose RC injuries (99% sensitivity and specificity).
