Acromioclavicular separation is a common athletic shoulder injury. While many can be treated nonoperatively, high-grade injuries can result in pain and loss of shoulder function. While numerous operative techniques have been proposed, a recent renewed focus on the anatomy of the coracoclavicular ligaments has led to anatomic reconstructive techniques that show promise in biomechanical compariso...

We present a case of failure of acromioclavicular joint (ACJ) reduction that was performed with low-profile, double-metallic button technique (Tightrope; Arthrex Inc). The patient presented with coracoid fracture and loss of reduction within eight weeks of surgery.

Acromioclavicular joint (AC) separations are one of the most common injuries seen in orthopedic and sports medicine practices, accounting for 9% of all injuries to the shoulder girdle. Various operative and nonoperative treatment schemes have been described for the management of AC joint injuries. Although there is controversy about the efficacy of surgical reconstruction versus nonoperative in...

INTRODUCTION Techniques for reconstruction of the dislocated acromioclavicular (AC) joint are numerous. Most, however, do not incorporate reconstruction of the disrupted acromioclavicular ligaments and capsule. Evidence exists supporting the importance of these ligaments particularly in providing horizontal stability to the AC joint. Recently, biomechanical studies have demonstrated improved AC...

Acromioclavicular (AC) joint arthropathy remains one of the most common causes of shoulder pain. In the case of AC joint arthropathy resistant to conservative treatment, most authors have recognized distal clavicle resection as the gold-standard treatment. However, some challenges remain to be solved. One is the difficulty in visualization of the superior and posterior part of the distal clavic...

This classic discusses the original publication “Treatment of acromioclavicular injuries, especially complete separation” by Weaver and Dunn, which collaborated to develop a technique for joint reconstruction in 1972. Their surgical described resection 2 cm distal clavicle transfer acromial end coracoacromial ligament into medullary canal clavicle. (modified) Weaver-Dunn procedures have been re...
