Distribution and Morphological Measurement of Bony Spurs on the Coracoid Process in a Chinese Population.

| Abstract |
BACKGROUND There are few studies on distributions or morphological measurements for bony spurs form at the attachment points of the ligaments and tendons on the coracoid process. The aim of this study was to investigate their most common sites and morphological characteristics, and to propose possible reasons. MATERIAL AND METHODS Scapulae with bony spurs on the coracoid process were selected from 377 intact and dry Chinese scapulae. The distribution, height, and transverse and longitudinal diameter of the bony spurs were measured in each coracoid process. RESULTS We selected 71 scapulae, 36 left and 35 right, that had bony spurs, from 377 scapulae. The bony spurs were most commonly located at the attachment point of the superior transverse scapular ligament (STSL) (31, 23.66%), while the trapezoid ligament (TL) accounted for the smaller proportion (8, 6.11%). The TSL was the highest, with the minimum transverse and longitudinal diameter, while the TL had the greatest transverse and longitudinal diameters. Only the TSL and TL had a statistically significant difference between the left and the right bony spur regarding the longitudinal diameter (P<0.05). CONCLUSIONS Bony spurs are more likely to form at the attachment points of ligaments and tendons on the coracoid process, which has a greater risk of traction injuries or attachment points avulsion fractures.
