| dc.description.abstract | Introducción El dolor de hombro afecta hasta el 67% de la población. La ruptura proximal del tendón largo del bíceps es una causa frecuente, cuyo diagnóstico se ve limitado por la disponibilidad de resonancia magnética. Este estudio evalúa la precisión del "Signo de Abril" como herramienta diagnóstica no invasiva y su relación con variables clínicas, demográficas y antropométricas. Metodología Estudio de casos y controles en 184 pacientes con diagnóstico clínico y confirmación por resonancia magnética. Los casos fueron pacientes con ruptura completa del tendón largo del bíceps. Se evaluaron el Signo de Abril, sensibilidad (S), especificidad (E), valor predictivo positivo (VPP) y negativo (VPN). Variables demográficas y clínicas se analizaron mediante pruebas t y chi-cuadrado, mientras que la relación entre la resonancia magnética y el Signo de Abril se evaluó usando un modelo de regresión binomial. Resultados La edad promedio fue mayor en los casos (64.76 años) que en los controles (58.45 años, p=0.011). Los hombres tuvieron mayor frecuencia de rupturas completas (62.07% en casos vs. 41.94% en controles, p=0.046). No hubo diferencias significativas en el IMC (25.86 vs. 25.32, p=0.3). El dolor (EVA) fue más intenso en los casos (7.59 vs. 7.01, p=0.036), y la capsulitis adhesiva (31.03% vs. 9.03%, p=0.003) y el síndrome del manguito rotador (44.83% vs. 20.65%, p=0.005) fueron más prevalentes. El Signo de Abril tuvo S=89.66%, E=94.19%, VPP=74.29% y VPN=97.99%, con una exactitud de 93.48% (kappa=0.7734). El coeficiente estimado para la resonancia fue de 4.945, lo que indica que por cada incremento unitario en el resultado de la resonancia, la probabilidad de un Signo de Abril positivo aumenta en un factor de 4.94 (p<0.001). Conclusiones El Signo de Abril se correlaciona fuertemente con los resultados positivos en la resonancia magnética, con un coeficiente de 4.945 que respalda su utilidad como herramienta predictiva. Además, variables como la edad avanzada, el sexo masculino, dolor intenso, capsulitis adhesiva y el síndrome del manguito rotador se asocian con mayor probabilidad de rupturas completas. El Signo de Abril es una alternativa diagnóstica precisa y accesible en contextos con recursos limitados. | spa |
| dc.description.abstractenglish | Introduction Shoulder pain affects up to 67% of the population. Proximal rupture of the long head of the biceps tendon is a common cause, but its diagnosis is often limited by the availability of magnetic resonance imaging (MRI). This study evaluates the accuracy of the "April Sign" as a non-invasive diagnostic tool and its relationship with clinical, demographic, and anthropometric variables. Methodology A case-control study was conducted with 184 patients diagnosed clinically and confirmed by MRI. Cases included patients with a complete rupture of the long head of the biceps tendon. The "April Sign" was assessed along with sensitivity (S), specificity (E), positive predictive value (PPV), and negative predictive value (NPV). Demographic and clinical variables were analyzed using t-tests and chi-square tests, while the relationship between MRI findings and the "April Sign" was evaluated using a binomial regression model. Results The average age was higher in cases (64.76 years) than in controls (58.45 years, p=0.011). Males had a higher frequency of complete ruptures (62.07% in cases vs. 41.94% in controls, p=0.046). No significant differences were found in BMI (25.86 vs. 25.32, p=0.3). Pain intensity (VAS) was higher in cases (7.59 vs. 7.01, p=0.036), and adhesive capsulitis (31.03% vs. 9.03%, p=0.003) and rotator cuff syndrome (44.83% vs. 20.65%, p=0.005) were more prevalent. The "April Sign" showed S=89.66%, E=94.19%, PPV=74.29%, and NPV=97.99%, with an accuracy of 93.48% (kappa=0.7734). The estimated coefficient for MRI findings was 4.945, indicating that for each unit increase in MRI results, the probability of a positive "April Sign" increased by a factor of 4.94 (p<0.001). Conclusions The "April Sign" strongly correlates with positive MRI findings, with a coefficient of 4.945 supporting its use as a predictive tool. Additionally, advanced age, male sex, severe pain, adhesive capsulitis, and rotator cuff syndrome are associated with a higher likelihood of complete ruptures. The "April Sign" is a precise and accessible diagnostic alternative in resource-limited settings. | spa |
