Dr. Garcia demonstrates his repair technique for posterior shoulder instability.

This video features Dr. Grant Garcia demonstrating his specialized surgical repair technique for posterior shoulder instability. This condition occurs when the humeral head subluxates or dislocates out of the back of the shoulder socket, which typically requires structural reinforcement of the posterior labrum and joint capsule.

The procedure centers on the following key clinical steps:

• Joint Exploration & Mobilization: Dr. Garcia begins by arthroscopically evaluating the glenohumeral joint from an anterior vantage point to assess the extent of the posterior damage. The detached posterior labrum is carefully mobilized off the glenoid rim using a specialized elevator to ensure it can be shifted back into its proper anatomical position.
• Creating a Healing Bed: A curved rasp or shaver is inserted to gently abrade and prepare the posterior bone rim. This creates a raw, bleeding bone footprint that triggers a natural healing response and allows for strong, biological tissue-to-bone bonding.
• Anchor Insertion & Labral Fixation: Using specialized drilling guides tailored for the posterior anatomy, Dr. Garcia places high-strength, low-profile anchors along the back edge of the glenoid. He takes precise tissue bites through the detached labrum and a measured portion of the capsule.
• Tensioning & Stabilization: The sutures are sequentially tensioned and locked down flush against the bone footprint. This plicates (tightens) the redundant, stretched-out posterior capsule and fully reconstructs the labral bumper.

The final inspection confirms that the posterior tissue barrier is securely restored, eliminating the abnormal backward sliding of the shoulder joint while protecting the native mechanics of the arm.
