Acromioclavicular joint (ACJ) disruptions account for %12 of all shoulder girdle injuresin general population and %40 in athletes.The conoid ligament provided the primary restraint to posterior translation, whereasthe AC ligaments remained the primary restraint to posterior translation.Glenohumeral injuries are a much more common epiphenomen duringacromioclavicular separation than previously ascertained.There are many treatment options available for surgical reconstruction of ACJinjuries but the literature dose not recommend any of these treatment options as the optimal method.preference has been given for tendon graft rather than screw fixation as anaugmentation method for reconstruction procedure because of lack of implantfracture ,loosening and migration of implants.Triple-bundle (TB) tendon graft ACJ reconstruction with combined anatomic CC andAC ligament replacement was developed.although still controversial,the authorsbelieve that all stabilising structures of ACJ complex should be reconstructed toachieve optimal result.
