Morphometry of the Glenoid Cavity of Dry Scapulae of Human Adults

Abstract

Objective: The shoulder joint is considered the most unstable in the human body and this is due to the measurement relationships between the bone surfaces of its components. This joint is subject to frequent dislocations, which can result in acute fracture or gradual bone loss, which can lead to recurrent instability, additional injury and pain. In this study, it was aimed to carry out a study of the maximum height and width measurements of the glenoid cavity of dry scapulae, correlating them with sex and dimidium. Methods: Measurements of the maximum heights and widths of 90 dry scapulae glenoid cavities were performed using a 0.01 mm precision digital caliper, 54 were males and 36 were females, with a mean age of 51.9 years. Values of p0.05). When we correlated the mean height and width of the GC with respect to homologous sides and sexes, they were also higher in males, but this finding was statistically significant (p<0.05). Conclusion: The findings of these measurements of the glenoid cavity represent a contribution not only for anatomy, but especially for orthopedists, when planning shoulder arthroplasty procedures, as well as helping the industry to develop more accurate and functional joint prostheses for the Brazilian population.
