STUDY ON MORPHOMETRIC FEATURES OF GLENOID CAVITY ON VIETNAMESE ADULTS

Abstract

Objectives: To study the morphometry of glenoid cavity on Vietnamese adults. Materials and methods: The study was performed on 15 Vietnamese adult corpses preserved at Department of Anatomy, Ho Chi Minh City University of Medicine and Pharmacy. The glenohumeral joints were dissected to measure superior-inferior and anterior-posterior diameters of glenoid cavity, and also classify the shape of the glenoid cavity. Results: The superior-inferior diameter of glenoid cavity in males and females were 30.682 ± 2.714 mm and 24.375 ± 2.875 mm, respectively. The upper anterior-posterior diameters of the glenoid in males and females were 17.273 ± 2.930 mm and 13.500 ± 1.309 mm, respectively. The lower anterior-posterior diameters of the glenoid in males and females were 21.682 ± 2.275 mm and 17.125 ± 3.044 mm, respectively. There were 3 types of glenoid cavity‘s shape: Type 3 (66.7%), type 2 (30%) and type 1 (3.3%). The differences between the right and left shoulder were not statistically significant with p > 0.05. Conclusion: The parameters of glenoid cavity in females tended to be lower than in men, but not statistically significant with p > 0.05. The glenoid cavity had 3 morphological shapes, mostly were oval-shaped (shape 3).
