“…The majority of these studies have been carried out on dry osteology [1, 3–7, 12–14], while others were done on cadavers [15–21]. In addition, few authors have performed morphometric analysis on in vivo populations using CT scans [11, 22, 23]. The large part of previously mentioned studies was done in different western populations.…”

Ethnic origin plays an important role in bone morphometry. Studies examining the influence of coracoid process have focused primarily on adults and have not included people from diverse Asian ethnic backgrounds. Our goal was to explore ethnic differences in morphometry of coracoid among Asian population. We performed morphometric measurements of coracoid process on cadaveric shoulders and shoulder CT scans from 118 specimens. The cadaveric sample included Indian (46%), Chinese (27%), and Myanmarese (27%) subjects, while the CT scans sample included Chinese (67%) and Malay (33%) subjects. The morphometric measurements were performed using digital caliper and software developed at Golden Horses Health Sanctuary (GHHS). In the Indian cadaveric shoulders, the coracoid process is better developed than the other groups with the exception of the tip width of coracoid process. There are significant differences in almost all measurements (P < 0.05) between the ethnic groups. On the other hand, the morphometry of coracoid process from CT scans data is bigger in Chinese than Malay subjects when stratified by sex (P < 0.05). Moreover, in all morphometric measurements, the females had smaller measurements than males (P < 0.05). Understanding such differences is important in anatomy, forensic and biological identity, and orthopaedic and shoulder surgeries.

“…In reviewing the literature, very little data was found on morphometry of the coracoid process on in vivo population using CT scans [11, 22, 23]. To the best of our knowledge, this is the first in vivo study in different Asian populations.…”

“…The screws must provide sufficient compression to encourage bone union and need to maintain their strength until the graft has healed sufficiently, typically at 3 months postoperatively. Finally, osteolysis or drill hole enlargement, which has been reported with the use of bioabsorbable implants for other applications, 2,3,23,38,42,44 could increase the risk of secondary fractures and recurrent shoulder instability.…”

“…The arthroscopic Latarjet technique described by Lafosse et al uses two 3.5 mm screws for fixation of coracoid. Armitage et al also measured the coracoid on CT scans and found the mean length, width to be 16.8 and 15 mm respectively [10]. Our study was done to assess the safe zone, which is free of coracoclavicular ligament attachment, hence raw measurements of the width and height of coracoid were not considered significant.…”

Background: Latarjet procedure is frequently done to treat shoulder instability. It includes osteotomizing the coracoid distal to the insertion of coracoclavicular ligament. Knowledge of the insertion of the trapezoid ligament is important to determine the level of coracoid osteotomy. Methods: Ten shoulders were dissected free of overlying soft tissue while preserving the ligament and muscle attachment on the coracoid. The distance between the tip of the coracoid to the coracoclavicular ligament and the pectoralis minor insertion width on the coracoid was measured. Result: The average distance from the tip of the coracoid to the trapezoid insertion was 2.6 cm. The average pectoralis minor insertion width was 1.9 cm. Conclusion: To preserve the insertion of the trapezoid ligament, the coracoid should be osteotomized less than 2.6 cm from the tip of the coracoid.
