Acromioclavicular dislocation (AC dislocation) is a common injury of the shoulder. In contrast to a traumatic cause, nontraumatic dislocation is very rare. We report on a 17-year-old female that presented with voluntary recurrent dislocation of the right AC joint followed by recurrent pain without instability of the ipsilateral shoulder.

Methods: In a historic cohort study we analysed all revised OUKAs that were primarily implanted at our clinic over a 10-year period (1998-2009). The primary aim was to investigate surgical difficulties encountered during revision surgery of the OUKA.
Purpose: To determine the best combination of anchors and suture techniques for repairing torn rotator cuff tendons.
Type Of Study: Ex vivo biomechanical investigation.
Methods: Sixty fresh-frozen sheep infraspinatus tendons were repaired using 6 different repair techniques: transosseous sutures with 2 sutures and mattress stitches; 2 suture anchors with 1 suture per anchor using either simple stitches, mattress stitches, or modified Kessler stitches; 2 suture anchors with 2 sutures per anchor using simple stitches; or 5 suture anchors with 1 suture per anchor and a mattress stitch pattern.
Background: The effectiveness of arthroscopic thermal capsulorrhaphy in the prevention of recurrent instability in primary anterior stabilization is undetermined.
Purpose: To determine if patients with recurrent anterior shoulder instability who have labral repair plus arthroscopic thermal capsulorrhaphy have better outcomes than those with labral repair alone.
Study Design: Cohort study; Level of evidence, 3.
