Abstract
BackgroundThe scapular is an important bony component of the upper limb and detailed knowledge of its anatomy helps when making surgical decisions regarding the scapular and surgical instruments utilized for scapular surgery.This study was conducted to determine the detailed osseous anatomy and morphometry of scapula obtained from Southwestern NigeriansMaterials and MethodsWe examined seventy‐eight dried adult scapula bones. All the scapulas were evaluated and dimensions obtained by a single investigatorResultsThe mean maximum distance between the highest point of the superior angle and the lowest point of the inferior angle was 14.6±0.15cm, (mean±standard error of mean, N= 78). The mean maximum scapular width was 10.4±0.1cm. The mean glenoid cavity height was 3.8±0.04cm and the mean glenoid cavity width was 2.6±0.03cm. The mean ratio of the maximum distance between the highest point of the superior angle and the lowest point of the inferior angle versus the mean maximum scapular width was 1.40±0.01. The mean ratio of the glenoid cavity height versus the mean glenoid cavity width was 1.43±0.02. The mean ratio of the maximum distance between the highest point of the superior angle and the lowest point of the inferior angle versus the mean glenoid cavity height was 3.9±0.03 while the mean ratio between the maximum scapular width versus the glenoid cavity width was 4.0±0.04.ConclusionThe ratio of the maximal length of the scapular versus the scapular width did not differ significantly from the ratio of the glenoid cavity height versus the glenoid cavity width. Also the ratio of the maximal scapular length to the glenoid cavity height did not differ significantly from the ratio of the maximal width of the scapular to the glenoid cavity width.Grant Funding Source: None
