Abstract
Introduction:
Acromioclavicular joint dislocations represent a frequent condition, affecting a very specific and generally active population and accounting for around 9% of all shoulder injuries.
Case Presentation:
We present a series of patients who underwent AC Joint reconstruction using Semitendinosus graft with internal bracing. The beach chair position is used for acromioclavicular reconstruction surgery. In this technique, we restore the anatomy, reconstruct the coracoclavicular ligament, and reinforced the acromioclavicular ligament. And it is reliable for chronic acromioclavicular joint injury. At final follow up we found excellent results with average pain score of 1.6, and average ROM of 160° of forward flexion and abduction, 70° of external rotation, and internal rotation level at T11. Postoperative function also showed great improvements with average ASES of 85 points, an average Constant Score of 89 points. This technique also achieved acceptable radiographic results, with an average coracoclavicular distance increase of 1.4 mm
Discussion & Conclusion:
The loss of AC joint congruence with the Weaver Dunn procedure suggested that possibly the problem wasn’t only biological. This technique seems to be especially advantageous as it allows for an anatomic, biological, and minimally invasive procedure while avoiding some of the inconveniences described in other reports. Although demanding, it can be reproducibly performed arthroscopically, and good clinical outcomes should be expected.
