Abstract:
Objective:To provide anatomic data of the coracoclavicular (CC) ligament attachment regions in Chinese population for anatomic reconstruction of CC ligament to treat acromioclavicular dislocation.Methods:The CC ligaments were first dissected layer by layer out of the bilateral acromioclavicular joint specimens taken from 87 adult cadavers. The CC width and thickness on the attachments of the clavicle and the coracoid process were measured by an electronic digital caliper. The conoid ligament and trapezoid ligament were mapped on the surface of the clavicle and the coracoid process by transecting the ligaments close to their insertions. The distances from the ligament footprint center to the lateral, anterior and posterior margins of the clavicle were measured. The distances from the ligament footprint center to the tip, medial and lateral margin borders of the coracoid process were measured.Results:The distances from the lateral edge of the clavicle to the footprint centers of the conoid and trapezoid ligaments were (35.7 ± 3.4) mm and (21.8 ± 2.7) mm, and the ratio of the distance divided by the clavicular length was 25.5% ± 0.9% and 15.6% ± 1.1%, respectively. The distances from the tip of coracoid to the footprint centers of the conoid and trapezoid ligaments were (35.1 ± 3.2) mm and (29.7 ± 2.9) mm, and the ratio of the distances divided by the coracoidal length was 86.7% ± 1.9% and 73.3% ± 2.1%, respectively.Conclusion:Although the absolute position of the CC ligament attaching to the clavicle and the coracoid process varies greatly among Chinese individuals, the ratio of its relative position to the length and width of the clavicle and the coracoid process is a relatively stable set of data.
