Acromioclavicular joint dislocations: coracoclavicular reconstruction with and without additional direct acromioclavicular repair

Abstract

Reconstruction of AC dislocations with one or two TRs leads to stable results with a higher stiffness than the native joints. For the PDS + AC group, axial stiffness was similar to the native situation, although there might be a risk of elongation. Direct AC repair showed no significantly increased stability in comparison with reconstructions without direct AC repair. Thus, a direct AC repair seems to be dispensable in clinical practice, while TRs or PDS cerclages appear to provide sufficiently stable results.

The frequency of reduction loss after arthroscopic fixation of acute acromioclavicular dislocations using a double-button device, and its effect on clinical and radiological results

“…AC repair was not performed in any of the patients in this study group since it requires wider dissection and longer surgery, it has higher morbidity and the additional stability is questionable. In a cadaver study, Weiser et al did not observe any additional stability with direct AC repair [19].…”

“…Mean time from injury to surgery was 6.8 ± 3.8 days (range, 2-14). The mean time to return to work was 11.2 ± 2.9 weeks (range, [8][9][10][11][12][13][14][15][16][17][18][19][20]. When trauma mechanisms are examined, 15 patients were injured while doing sports, 14 patients were injured after a traffic accident, 5 patients were injured after falling from height and 2 patients were injured during a fight.…”

Reconstruction of the Acromioclavicular Ligament Complex Using Dermal Allograft: A Biomechanical Analysis

“…Load to failure and cyclic loading was not performed, as these typically are loaded to test vertical stability, which has been shown previously to be regulated by the CC ligaments. 2,8 Each of the 6 specimens were tested in 4 different conditions. First, the intact AC joint was tested and used as a control.…”

“…Therefore, recent biomechanical and clinical studies have advocated for reconstruction or repair of both the CC and AC capsule for stabilization. [4][5][6][7][8][9][10] The acromioclavicular ligament complex (ACLC) has been reported as the primary posterior stabilizer of the AC joint. [11][12][13][14] A previous biomechanical study demonstrated that dissection of the entire ACLC (with intact CC ligaments) reduced the resistance force of the AC joint against posterior translation to less than 25% when compared with the native ligament complex.…”
