喙锁韧带重建的解剖学研究和临床意义

Anatomic study on reconstruction of coracoclavicular ligaments and clinical significance

目的测量喙锁韧带相关解剖学数据,为肩锁关节脱位手术中完全解剖重建喙锁韧带提供必要的解剖学依据。方法 15具（30肩）成人尸体标本,分别标记斜方韧带和锥状韧带锁骨止点中心,测量韧带锁骨止点中心与锁骨骨性标志的相关解剖学数据。结果斜方韧带锁骨止点中心与锁骨远端、前缘、后缘的距离分别为（21.87±1.12）mm（19.8~24.0 mm）、（6.34±0.45）mm（5.5~7.2 mm）、（20.47±1.02）mm（18.9~22.1 mm）;锥状韧带锁骨止点中心与锁骨远端、前缘、后缘的距离分别为（36.69±0.92）mm（35.0~38.5 mm）、（15.71±0.56）mm（14.8~17.0 mm）、（5.53±0.39）mm（5.0~6.3 mm）。结论喙锁韧带锁骨止点中心与骨性标志的距离的测量,将有利于术者行肩锁关节脱位手术时完全解剖重建喙锁韧带。

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（14.8-17.0mm）,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.
