Objetivos: El propósito del estudio era evaluar la morfología de acromion adulto en la población India y correlacionar su asociación con varias patologías del hombro. Materiales y métodos: La evaluación morfológica fue realizada en 200 omóplatos secos adultos obtenidos del museo de osteología del Departamento de Anatomía, Maulana Azad Medical College, Nueva Delhi. Se calculó la altura del arco acromial, ángulo anterior y posterior del arco y su índice, usando el método objetivo de Getz et al (1996) para demarcar forma acromial. La presencia o la ausencia de entesofitos fue observada en la superficie inferior de la cara anterior del acromion. Resultados: 28% de los omóplatos fueron el acromion de tipo I, 67% fueron el tipo II y el 5% fueron el tipoIII. La presencia de entesofitos en la superficie inferior de la cara anterior del acromion también fue estudiada; los enthesofitos fueron observados en 3.5% en el tipo acromial I, 15.67% en el tipo II y el 40% en el proceso acromial de tipoIII. Conclusiones: La asociación entre el síndrome subacromial de compresión y el tipo acromial está bien establecida. Les asistirá a los clínicos para decidir la modalidad del tratamiento: conservador o quirúrgico. Se debe tener en cuenta la asociación de entesofitos subacromiales con la morfología acromial y los desgarros del manguito rotador al interpretar opacidades en las radiografías.
Objectives: The purpose of the study was to asses the morphology of adult acromion processes in Indian population and correlate its association with various shoulder pathologies. Materials and methods: Morphologic evaluation was conducted on 200 adult dry scapulae obtained from osteology museum of Department of Anatomy, Maulana Azad Medical College, New Delhi. The height of the acromial arch, anterior and posterior angle of arch and their ratio were measured by using objective method of Getz et al (1996) for determining acromial shape. Presence or absence of enthesophyte was noted on the undersurface of the anterior aspect of the acromion process. Results: 28% scapulae exhibited type I acromion, 67% exhibited type II and 5% exhibited type III. The presence of enthesophytes on the anterior undersurface of the acromion was also studied; enthesophytes were observed in 3.5% in type I acromion, 15.67% in type II and 40% in type III acromion process. Conclusions: Association between subacromial impingement syndrome and acromial type is well established. This will assist the clinicians in deciding the modality of treatment: conservative or operative. Association of subacromial enthesophytes with acromial morphology and rotator cuff tears should be borne in mind when interpreting opacities on radiographs.
