Arthroscopic Acromioclavicular Joint Treatment With Coracoclavicular Fixation and Allograft Coracoclavicular Ligament Reconstruction for Acute Acromioclavicular Dislocations

“…Finally, ACJ reduction should be performed in a controlled manner and confirmed fluoroscopically to reduce the risk of adjacent structure injury and to mitigate the risk of malreduction, which has been reported as a complication in up to 30% of cases. 7 Our technique uses a tensioning device to reduce, in a controlled fashion, the superiorly migrated clavicle to the acromion. Prior techniques of manually forcing the clavicle inferiorly with an instrument while axially loading the arm superiorly to elevate the acromion 8 are imprecise and potentially dangerous because the instrument on the superior clavicle can easily slip and injure the neurovascular structures just underneath the clavicle.…”

All-arthroscopic, Guideless Single Suture-button Fixation of Acute Acromioclavicular Joint Dislocation: A Description of the Technique and Early Treatment Results

“…7) Until now, all relevant studies have been performed using the arthroscopically-assisted technique with the aid of a drill guide and an image intensifier during the placements of clavicular and coracoid holes. Threedimensional C-arm flat detector navigation has even been suggested.…”

Coracoclavicular ligaments anatomical reconstruction: a feasibility study

“…It seems that the conoid and trapezoid ligaments should not be considered as one structure when surgical treatment is undertaken. AC joint reconstruction techniques have recently focused on anatomical restoration of the CC ligaments .…”

“…Anatomical reconstruction of the CC ligamants provides superior biomechanical stability and shows good to excellent clinical results in AC joint dislocation treatment . However, it is technically difficult to safely and accurately create bony tunnels at the remaining stumps of the ruptured ligaments.…”

“… recently assessed transclavicular–transcoracoid CC ligament reconstruction performance, to our knowledge there are no data describing the risk of two‐bundle reconstruction. Such information is necessary to evaluate the safety and reliability of truly anatomical CC ligament reconstruction, in particular because two‐bundle reconstruction techniques have lately become popular . The purpose of this study was therefore to assess the feasibility of anatomical CC ligament reconstruction, using three‐dimensional (3D) measurement and virtual drilling.…”
