Has your shoulder ever felt loose, slipped out of place, or felt like it was about to? That unsettling feeling is known as shoulder instability. It happens when the structures that hold the “ball” of your upper arm bone (the humeral head) securely in its shallow “socket” (the glenoid) are stretched, torn, or damaged. For active individuals in the San Francisco Bay Area, a stable shoulder is crucial for everything from carrying groceries to enjoying sports like swimming, tennis, or baseball.
At California Pacific Orthopaedics, our team of board-certified shoulder specialists understands how disruptive and painful an unstable shoulder can be. We are dedicated to providing comprehensive care, from accurate diagnosis to advanced surgical treatments, designed to restore your shoulder’s strength, stability, and function. This page will guide you through the basics of shoulder instability and explain how surgical repair can help you get back to your life without fear of dislocation.
Common Symptoms and Causes of Shoulder Instability
Recognizing the signs of shoulder instability is the first step toward getting the right treatment. While a full dislocation is an obvious and painful event, the symptoms can sometimes be more subtle.
Common Symptoms:
- Sensation of Looseness: A feeling that the shoulder is about to slip or “give way.”
- Repeated Dislocations or Subluxations: The shoulder may pop completely out of the socket (a dislocation) or partially out (a subluxation) before slipping back in.
- Pain: Aching or sharp pain in the shoulder joint, which can be constant or only occur with certain movements.
- Clicking, Popping, or Catching: Audible or physical sensations in the joint during movement.
- Loss of Strength: Difficulty or weakness when lifting your arm or carrying objects.
- Numbness or Tingling: A “dead arm” feeling or tingling that radiates down the arm, often after a subluxation or dislocation.
Common Causes:
- Traumatic Injury (Acute Dislocation): This is the most common cause. A sudden, forceful blow to the shoulder, a fall onto an outstretched arm, or a violent twisting motion can force the ball out of the socket. This often tears the labrum (a ring of cartilage that deepens the socket) and stretches the ligaments (the strong bands that connect bones). This type of injury is frequent in contact sports like football and rugby.
- Repetitive Overhead Motion (Microtrauma): Athletes who perform repeated overhead motions—such as swimmers, pitchers, and volleyball players—can gradually stretch out their shoulder ligaments over time. This leads to a loose joint that becomes unstable without a single major injury. This is sometimes called “atraumatic instability.”
- Genetic Hypermobility (Ligamentous Laxity): Some individuals are naturally “double-jointed,” meaning their ligaments are looser than average throughout their bodies. This can make their joints, including the shoulder, more prone to instability without any specific injury.
Common Risk Factors
Certain factors can increase your likelihood of developing shoulder instability:
- Age: Young adults and teenagers are most susceptible, particularly those active in sports.
- Previous Dislocation: Once you’ve dislocated your shoulder, you are significantly more likely to do it again.
- Participation in Contact or Overhead Sports: Football, hockey, gymnastics, swimming, and tennis put significant stress on the shoulder joint.
- Genetic Predisposition: A family history of joint laxity.
Why Is Shoulder Instability Repair Surgery Performed?
While non-surgical treatments like physical therapy and activity modification are often the first line of defense, they aren’t always enough. When the shoulder continues to be unstable, surgery becomes the most effective option to prevent long-term damage and restore quality of life.
The primary goals of shoulder stabilization surgery are to:
- Prevent Future Dislocations: Re-injury can cause further damage to cartilage and bone, increasing the risk of developing arthritis later in life. Surgery tightens and repairs the damaged structures to keep the joint in place.
- Eliminate Pain and Apprehension: Constant worry about your shoulder popping out can cause you to avoid activities you love. Surgery aims to create a stable, trustworthy joint so you can move with confidence.
- Restore Function and Strength: By securing the joint, surgery allows you to rebuild strength and return to high-level activities and sports.
Your surgeon at California Pacific Orthopaedics may recommend surgery if you have experienced recurrent dislocations, feel your shoulder is too unreliable for daily activities, or if non-surgical treatments have failed to solve the problem, especially if you are a young, active athlete.
What to Expect: Your Surgical Journey
Deciding to have surgery is a significant step, and our team is here to support you through the entire process. Here’s what you can expect before, during, and after your procedure.
Before the Procedure
Your journey begins with a thorough consultation at one of our San Francisco locations. Your surgeon will discuss your symptoms, perform a physical examination, and review imaging tests like an X-ray or MRI to assess the damage to your labrum, ligaments, and bone.
Once surgery is scheduled, our team will provide you with pre-operative instructions. This may include guidelines on eating and drinking, stopping certain medications, and arranging for someone to drive you home. This is the perfect time to ask any final questions you may have.
During the Procedure
Shoulder stabilization surgery is typically performed under general anesthesia, and you may also be given a nerve block to help manage pain after the procedure. There are two main surgical techniques:
- Arthroscopic Repair (Bankart Repair): This is the most common, minimally invasive approach. The surgeon makes several small incisions around your shoulder and inserts a tiny camera (arthroscope) to view the inside of the joint on a screen. Using specialized miniature instruments, the surgeon repairs the torn labrum and tightens the stretched ligaments. A Bankart repair, a common type of arthroscopic stabilization, specifically involves re-attaching the torn labrum to the rim of the glenoid (socket) using small anchors.
- Open Surgery (Latarjet Procedure): In cases of severe instability, significant bone loss from the socket, or when a previous arthroscopic repair has failed, an open procedure may be necessary. The Latarjet procedure is a type of open surgery where the surgeon transfers a piece of bone from another part of your shoulder blade (the coracoid process) to the front of the socket. This creates a bone block that acts as a bumper, preventing the humeral head from dislocating.
Your San Francisco-based surgeon at California Pacific Orthopaedics will determine the best surgical approach for your specific condition.
After the Procedure
Recovery is a crucial part of the process and requires your active participation.
- Immediately After Surgery: You will wake up in a recovery room with your arm in a sling to protect the surgical repair. Most patients can go home the same day. Pain will be managed with medication.
- The First Few Weeks (Immobilization): You will need to wear the sling for approximately 4 to 6 weeks. During this time, it’s vital to let the repaired tissues heal. You will be given gentle exercises, like moving your wrist and elbow, to prevent stiffness.
- Physical Therapy (Rehabilitation): This is the key to a successful outcome. You will begin formal physical therapy a few weeks after surgery. Your therapist will guide you through a progressive program to first restore your range of motion, and then gradually rebuild strength in the shoulder muscles.
- Returning to Activities: The recovery timeline varies for everyone. Most people can resume light daily activities within a few weeks. A return to desk work may happen in 1-2 weeks, but more physically demanding jobs will require more time. A full return to contact sports and heavy overhead activities typically takes 4 to 6 months, once you have regained full motion and strength.
