Objetivo: El propósito del presente estudio es evaluar la geometría del acromion en relación con las ruptura del manguito de los rotadores. Materiales y métodos: Se utilizaron 30 pares de escápulas, 20 del sexo femenino y 10 del sexo masculino, con una edad promedio de 82 años (con intervalo de 62 a 101 años). Las escápulas fueron escaneadas y las mediciones se realizaron con un digitalizador Microscribe 3D y el software de rinoceronte. Principales Resultados: La media encontrada para el ángulo de inclinación acromial y la vertiente fueron 38,70 ± 5,91° y 48,87 ± 9,94° respectivamente. La media de los ángulos acromial lateral y acromio-glenoideo fueron 81,13 ± 8,72° y 182,80 ± 12,09°, respectivamente. Las distancias entre el acromial (la extremidad anterior y posterior) y el glenoideo fueron 28,7 ± 3,77 mm y 20,75 ± 4,45 mm, respectivamente. Los ángulos entre el acromion y la glena son más grandes en el lado izquierdo en comparación con el lado derecho, 186.49° y 179,16° (P <0.05). La distancia entre el acromial posterior y el glenoideo mostró una diferencia significativa (P <0,05) entre los sexos (23,13 mm para el sexo femenino  y 26,37 mm para el sexo masculino). Conclusión: No hubo diferencias significativas en relación a las roturas del manguito de los rotadores. La comprensión de la geometría del acromion es importante para mejorar las técnicas quirúrgicas en la cirugía del hombro.


Objectives: The purpose of this study is to evaluate acromion geometry in relation to rotator cuff tears. Materials and Methods: Thirty pairs of scapulae from 20 females and 10 males, average age 82 years (range 62 to 101 years), were scanned and measurements taken using a 3D microscribe digitizer and Rhino software. Main Results: The mean angles of acromion tilt and slope were 38.70± 5.91° and 48.87± 9.94° respectively, while those for lateral acromial and acromial to glenoid were 81.13± 8.72° and 182.80± 12.09°, respectively. The acromial (anterior and posterior tip) to glenoid distances were 28.7 ± 3.77 mm and 20.75 ± 4.45 mm, respectively. Left shoulders also were showed higher angles (P<0.05) of the acromion to glenoid than right, 186.49° and 179.16°. Posterior acromial to glenoid distance showed a significant difference (P<0.05) between females and males, 23.13 mm and 26.37 mm, respectively. Conclusion: There were no significant differences in relation to rotator cuff tears. Understanding the geometry of the acromion will improve surgical intervention in shoulder surgery
