Abstract

Objective To measure anatomic data of the coracoclavicular ligaments and provide necessary anatomic evidence for complete anatomic reconstruction of coracoclavicular ligaments for surgical treatment of dislocation of acromioclavicular joint. Methods A total of 15 adult cadavers (30 shoulders) were selected. The centers of trapezoid ligament and conoid ligament on the clavicle were marked and anatomic data between centers and bone landmarks on the clavicle was measured. Results The distances from the center of trapezoid ligament on the clavicle to the lateral end, anterior border, and posterior border of clavicle were (21.87±1.12) mm (19.8-24.0 mm), (6.34±0.45) mm (5.5-7.2 mm), and (20.47±1.02) mm (18.9-22.1 mm), respectively. The distances from the center of conoid ligament on the clavicle to the lateral end, anterior border, and posterior border of clavicle were (36.69±0.92) mm (35.0-38.5 mm), (15.71±0.56) mm (14.8-17.0 mm), and (5.53±0.39) mm (5.0-6.3 mm), respectively. Conclusion Measurement of the distances between centers of trapezoid ligament and conoid ligament on the clavicle and bone landmarks is helpful for complete anatomic reconstruction of coracoclavicular ligaments for surgical treatment of dislocation of acromioclavicular joint.
