Arthroscopic Knotless Subscapularis Bridge Technique for Reverse Hill-Sachs Lesion With Posterior Shoulder Instability.

Posterior shoulder dislocations are an uncommon cause of glenohumeral instability; they are frequently missed and are associated with humeral head defects and capsulolabral lesions. Despite surgical treatment often being mandatory, there is still no standardized treatment for anterior impaction fractures of the humeral head (reverse Hill-Sachs lesions). Arthroscopic surgery is typically indicated, with a tendency toward resorting to knotless techniques in recent years.

Latarjet Cerclage: The Metal-Free Fixation.

The Latarjet technique is a widely used technique for anterior shoulder instability with glenoid bone defects, irreparable capsuloligamentous lesion, or in patients at greater risk of recurrence. The use of this technique has been reported to obtain satisfactory clinical and biomechanical results. Although other methods exist, the coracoid process is typically fixed with 2 metal screws.

Arthroscopic "Bone Block Cerclage" Technique for Posterior Shoulder Instability.

Many open and arthroscopic techniques have been described to treat posterior glenohumeral instability. Multifactorial features of posterior shoulder instability pathoanatomy and varied patient characteristics have challenged the understanding of this condition and have led to dissimilar results, without a strong consensus for the most adequate technique to treat it. We describe an arthroscopic anatomical metal-free posterior glenoid reconstruction technique, using a tricortical iliac crest allograft with 2 ultra-high strength sutures (FiberTape Cerclage System; Arthrex, Naples, FL) with concomitant posterior capsulolabral complex reconstruction procedure.
