Biomechanical Evaluation of a Single- Versus Double-Tunnel Coracoclavicular Ligament Reconstruction With Acromioclavicular Stabilization for Acromioclavicular Joint Injuries

Abstract

This study suggests that the ST CC ligament reconstruction has biomechanical properties equivalent to the DT CC ligament reconstruction with less theoretical risk of clavicle fracture.

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

“…In a biomechanical study by Beitzel et al [13], there was no difference in stability between the single and double device; nevertheless, the coracoid fracture incidence was much higher with the double device. Likewise, a recent study demonstrated that single tunnel reconstruction demonstrates similar biomechanical properties to the intact state and double tunnel reconstruction [9].…”

“…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.…”

“…In order to solve complications such as reduction loss, techniques including opening of a second tunnel [9], supporting the existing tunnel with anchor to the coracoid [10] and using tendon graft [11] have been proposed by different authors. However, none of these techniques have been widely accepted.…”

Arthroscopically Assisted Comprehensive Double Cerclage Suture Fixation Technique for Acute Acromioclavicular Joint Separation

“… 14 In that context, some authors preconized the use of a single-tunnel technique because, despite the high success rates of double-tunnel anatomical techniques, it can be a more suitable option to minimize fracture risk. 15 , 16 , 17 …”

Is the Position of Coracoid Button Important in Acromioclavicular Joint Dislocation Treatment with the Suture-Button?

“…Producers of implants used in everyday orthopedic and traumatologic practice meet this demand. Unfortunately, the proposed stabilization methods of the disruption of tissue continuity or the reconstruction of the bony tissue loss and especially of the damaged soft tissues are often based on static mechanical studies that do not take into account the complexity or the specificity of individual patients [1][2][3]. Therefore, it is all the more crucial to work out strict recommendation criteria for the industryproposed implants.…”
