Editorial Commentary: Arthroscopically Assisted Acromioclavicular Joint Reconstruction-Not Seeing Does Not Mean Do Not Worry.

To minimize risks during arthroscopic-assisted reduction and internal fixation of acromioclavicular dislocation, drilling should only be performed with an anatomically reduced clavicle. This re-creates the important distances to the neurovascular structures because a posteriorly displaced clavicle reduces the distance to the suprascapular nerve. In addition, visualization is of high importance for the arthroscopic coracoid preparation, as are mini-open incisions, to create an accurate and well-placed tunnel for drilling. Last, because the highest potential risk of neurovascular injuries occurs with the drilling itself instead of the final construct, all possible assistance and supports guiding the surgeon should be used to avoid any pitfalls. Hence, radiography and arthroscopy are helpful tools to create and check precise tunnel placement. Still, there are risks, and surgeons must be aware of and mitigate against neurovascular complications.
