Introduction to Shoulder Instability with Dr. Garcia

In this video, Dr. Grant H. Garcia introduces the concept of shoulder instability, addressing a topic that frequently generates questions from both patients and other orthopedic surgeons.

Here is a summary of the key insights he shares:

• What is Shoulder Instability? Shoulder instability occurs when the shoulder joint dislocates, popping out of its socket either through the front (anterior) or the back (posterior). The joint might stay dislocated, or it may pop back into place on its own.
• The Problem with Subluxation/Dislocation: When a shoulder goes in and out of the socket, it generally damages the surrounding anatomy. While it doesn't always mean surgery is required immediately, it does mean the shoulder should be clinically evaluated right away to see what has been compromised.
• Labrum vs. Bone Damage:
  • Labral Tears: Most commonly, a dislocation damages the labrum—the ring of cartilage that pads the socket. In many cases involving isolated labral tissue damage, doctors can choose to monitor the injury over time rather than rushing straight into surgery.
  • Bone Fractures: Occasionally, a dislocation can actually break off a piece of the socket's bone. Dr. Garcia uses the analogy of a golf tee breaking to explain this. If a piece of bone is chipped or pulled off during the dislocation, the issue needs to be addressed and fixed much more promptly.
• Evolving Clinical Data: He mentions that while more and more medical studies suggest treating shoulder dislocations earlier rather than later, standard medical practice still doesn't automatically dictate immediate surgery after a single, first-time dislocation unless significant bone damage is present.
