Shoulder instability — understanding the feeling of looseness, causes, and treatment options.
What you're feeling
You may feel pain in your shoulder that signals larger tissue damage. This pain often acts as a warning sign when you have shoulder instability. You might notice discomfort when reaching behind your back to fasten a bra or tucking in a shirt. Simple daily tasks can become difficult if your shoulder feels loose or painful.
Your symptoms can vary depending on the type of instability you have. If you have posterior instability, the condition is often hard to diagnose and can be technically challenging to treat. You might experience pain during motion without a clear feeling of the joint slipping out. Some patients feel minor instability that presents as extra-joint impingement symptoms. Pain can also flare up at night or after activity, making it hard to sleep on that side.
In some cases, you may have microinstability, which is difficult to diagnose. Young patients often report ambiguous shoulder pain during movement without a full dislocation. If you have recurrent posterior instability, the condition can be difficult to treat but reliable recovery is possible with modern arthroscopic management. Your surgeon will look closely at your bone loss and specific pathology to determine the best path forward for your recovery.
What's actually happening
Your shoulder is a ball-and-socket joint that relies on a tight sleeve of tissue called the joint capsule to stay in place. When you have instability, this sleeve stretches or tears, allowing the ball to slip out of its socket. This movement is not normal. Even a small change in how your shoulder moves, known as a 5% shift in motion, can alter how the joint works and cause pain.
The problem often involves the soft tissues that act like ropes and gaskets around the joint. Tears in these tissues, especially the subscapularis tendon, change how your shoulder handles weight and movement. This can cause the ball to slide forward or upward more than it should. While surgery aims to tighten these tissues, no current method can fully restore your shoulder to its exact pre-injury state.
Your surgeon looks at your specific bone loss and tissue damage to decide the best path. For some, the Latarjet procedure offers a durable solution for long-term stability. However, surgery is not done just to prevent future games or boost performance. The goal is to fix the mechanical failure so you can move without fear of the joint slipping again.
What we can do about it
Your journey often begins with self-management and physiotherapy. You might try resting the shoulder and avoiding movements that cause it to slip out. Physical therapy aims to strengthen the muscles around your joint to keep it stable. This non-surgical approach is often the preferred strategy if your chance of the shoulder slipping again is low after this care. However, please know that nonoperative treatment can carry substantial societal costs for you and your community. While this path may help you return to play faster, it does not prevent future dislocations as well as surgery does.
If pain persists, your surgeon may discuss medical management options. These include pain medication and anti-inflammatories to help you feel better in the short term. In some cases, injections like cortisone or hyaluronic acid might be used to reduce swelling and pain. While these treatments can provide relief, the evidence does not specify exactly how long the effect lasts for every person. Your surgeon will decide if these are right for you based on your specific symptoms and exam.
Surgery is considered when conservative care has reached its limit or if you are young and at high risk for recurrence. Your surgeon may recommend stabilization to restore joint stability while minimizing loss of motion. This is especially true for adolescents and young adults under 40 years of age with a first-time dislocation, where surgery is more effective than non-surgical options. The goal is to stop the shoulder from slipping out again so you can enjoy a longer, more active career.
When to see someone
See your GP if you have persistent shoulder pain that does not improve with rest. Ask for a specialist review if your shoulder feels weak, unstable, or gives way. You should also seek help if the joint locks or symptoms interfere with your sleep or work. Sudden worsening of symptoms is another reason to consult. Recurrent instability occurs in roughly one-third of patients under 40 after an initial dislocation. If you have a history of dislocation, long-term follow-up is important as outcomes can change over time.
