title: Open anatomical coracoclavicular ligament reconstruction using a tendon graft with an Endobutton loop.
abstract: We describe a technique of open anatomical coracoclavicular ligament reconstruction restoring both parts of the native ligament, aiming at achieving maximum stability of the acromioclavicular joint without disturbing the normal anatomy. Using the same anatomical principle of ligament reconstruction as in other joints, transosseous tunnels are created at the native footprints of the conoid and trapezoid ligaments. An autologous graft is fixed using an Endobutton continuous loop and a PEEK screw; adequate healing of the ligament is ensured with an appropriate working length. Although an open procedure, this technique offers several advantages. It can be easily reproduced using basic anatomical principles and simple cost-effective instrumentation. The implant does not have to be removed, important anatomical structures are respected, normal acromioclavicular joint kinematics are restored, the scar is cosmetically acceptable and post-operative morbidity is very low.
