Scapula Morphometry of Adult Nigerians in the Southeast

Abstract

Twenty-five adult bony Scapulae of Nigerians were used to report detailed bony dimensions of the scapula. The average length of the scapulae was 146.24+6.78mm. The mean spine length was 126.83+7.29mm and acromial dimensions were 45.46+4.03 x 21.91+2.07 and 7.36+1.30 thick (mm). Glenoid dimensions showed that anteroposterior diameter = 26.54+1.86mm, supero-inferior diameter = 37.72+1.65mm and diameter at glenoid constriction = 19.58+1.35(mm). Coracoid dimensions were 39.20+2.67mm x 9.30+2.12 x 14.48+1.36mm. The average diameter of scapular notch was 14.90+2.94mm. Also 52% of Scapula notch were U-shaped and 92% of acromion were curved. The average thickness of the lateral boarder was 11.72+1.23mm. Glenoid dimensions correlated with all acromial dimensions except the acromial thickness. This detailed study of scapula dimensions will provide information for surgical procedures and detection of significantly displaced scapular fracture.
