| Abstract: | Objetivo: La prevalencia de las lesiones del manguito rotador son altamente frecuentes, actualmente no se entiende completamente sus causas. Pronosticar dichas lesiones es sumamente difícil y han sido objeto de estudio por varias décadas. Este estudio pretende determinar la relación que existe entre rupturas del manguito rotador y el ángulo crítico del hombro en pacientes del Hospital Universitario de Caracas. Método: se realizó un estudio descriptivo y transversal en el cual se estudiaron 50 voluntarios entre los 50 y 85 años de edad. Se examinaron bilateralmente 100 hombros, a los cuales se les realizó una radiografía AP neutra de hombro y una ecografía musculoesquelética del hombro. A las radiografías se les determinó el ángulo crítico del hombro, clasificándolos con un ángulo mayor a 35° y menor a 35°. En la ecografía se determinó el estado del manguito rotador clasificándolo entre no ruptura del manguito y ruptura del manguito rotador. Resultados: el promedio del ángulo crítico fue de 34,2° ± 3,0°. Se demostró una correlación entre el ángulo crítico del hombro mayor a 35° y rupturas del manguito rotador (p = 0,001). No hubo relación alguna entre el ángulo crítico del hombro y el estado del manguito rotador con respecto a la edad y sexo de los voluntarios. Conclusión: se determina que ángulos críticos por encima de 35° predicen rupturas del manguito rotador. Estos hallazgos sugieren que la diversidad de la anatomía individual puede producir cambios biomecánicos en la patologías degenerativa articular. |
| Description: | Objective: the prevalence of rotator cuff tears is very common, at the present time their causes have not been completely understood. Predicting these lesions are extremely difficult and has been object of study for the past decades. The purpose of this study was to determine whether there is an association between the critical shoulder angle and rotator cuff tears in patients of the University Hospital of Caracas. Method: a descriptive cross-sectional study was performed. Fifty volunteers were obtained between 50 and 85 years of old. One hundred bilaterally shoulders were examined, and they had AP true shoulder radiographs and a musculoskeletal ultrasound. The radiographs were analyzed and the critical shoulder angle were determined, classifying them with an angle higher than 35° and lower than 35°. In the ultrasound was determined the status of the rotator cuff, and were classified as rotator cuff tear and non-rotator cuff tear. Results: the mean critical shoulder angle was 34.2 ° ± 3.0°. There was a significant correlation between the critical shoulder angle higher than 35° and rotator cuff tears (p = 0.001). A significant different was not found between the critical shoulder angle and rotator cuff tears regarding the age and the sex of the volunteers. Conclusion: these findings suggests that critical shoulder angles higher than 35° could help predict rotator cuff tears. This suggests that the diversity of the individual anatomy could produce biomechanical changes in degenerative joint disease. |
