Anatomical and Anthropological Investigation of the Articular Surface of the Human Glenoid Cavity in Brazilian Corpses
The glenoid cavity of the scapula shows high morphological variability that has not been clearly elucidated in the literature. Its morphological aspects knowledge can be used in the sex determination, to improve the development of more functional prostheses and in the accurate image diagnostic. The purpose of the present study was to analyze and compare sex and dominance differences in the articular surface of the human glenoid cavity. Anthropometric measurements of the glenoid cavities of scapula were taken of 200 specimens, besides we developed a morphological classification system according the shape of inferior and superior poles and the presence of the glenoid notch in the anterior margin. For all anthropometric parameters, the male scapula showed higher values than the measures in female scapula both in right and left sides, but we did not find a significant difference between the left and right scapula in either sex. On the other hand, taking into consideration the anthroposcopic aspects, 50% of male and 58% of female were classified in a different morphological group when compared to the contralateral glenoid in the same individual. The present study revealed an evident sexual dimorphism and provides information about the articular surface of normal glenoid cavities to improve the diagnosis of orthopedic lesions, to produce better prosthesis and to improve the medico-legal identification
