Low prevalence of relevant associated articular lesions in patients with acute III-VI acromioclavicular joint injuries.

Purpose: To define the prevalence of associated articular injuries in patients with severe (Rockwood's III-VI) acute acromioclavicular joint injuries and to find out how many of these were associated with the traumatic event and required surgical treatment.

Methods: Retrospective observational multicentric study performed in ten centres included patients who required surgery for acute acromioclavicular joint injuries between 2010 and 2017. The inclusion criteria were: presence of an acute acromioclavicular joint injury (grades III-IV-V-VI) and surgical treatment within 3 weeks of injury that included a full arthroscopic evaluation of the shoulder.

Biomechanical analysis of acromioclavicular joint dislocation repair using coracoclavicular suspension devices in two different configurations.

Background: The best treatment option for some acromioclavicular (AC) joint dislocations is controversial. For this reason, the aim of this study was to evaluate the vertical biomechanical behavior of two techniques for the anatomic repair of coracoclavicular (CC) ligaments after an AC injury.

Materials And Methods: Eighteen human cadaveric shoulders in which repair using a coracoclavicular suspension device was initiated after injury to the acromioclavicular joint were included in the study.
