After a shoulder dislocation, the most important thing you can do is keep the joint completely still and get to an emergency room. Do not try to push the shoulder back into place yourself. Forcing the joint can damage muscles, ligaments, nerves, or blood vessels, and there may be a fracture that needs to be ruled out with imaging before the shoulder is repositioned.
Immediate Steps Before You Reach the ER
Immobilize the arm in whatever position it’s in. If you have a sling, use it. If not, hold your arm against your body or have someone help you fashion a makeshift support from clothing or a towel. The goal is zero movement at the shoulder joint.
Apply ice to the injured shoulder right away. A cold pack, a bag of frozen vegetables, or ice wrapped in a cloth all work. Keep it on for 15 to 20 minutes at a time. Ice controls swelling, limits internal bleeding around the joint, and reduces pain while you wait for medical help. Over-the-counter pain relievers like ibuprofen or acetaminophen can also take the edge off, but the real relief comes once the joint is professionally reduced (put back in place).
What Happens at the Hospital
A doctor will typically order X-rays before touching your shoulder. This matters because fractures around the upper arm bone are a direct contraindication to standard reduction techniques. If a fracture is missed and someone manipulates the joint, the damage can be far worse than the dislocation itself.
Once fractures are ruled out, the medical team will reposition the shoulder using one of more than 20 recognized techniques. Some involve gentle traction, others use leverage or scapular manipulation. You’ll usually receive some combination of pain medication, a muscle relaxant, or sedation beforehand, since the muscles around a dislocated shoulder go into spasm. In rare cases, general anesthesia is needed. The entire reduction process is usually quick once the medication takes effect, and the relief afterward is significant.
The First Two Weeks: Protection Phase
You’ll leave the hospital in a sling. The first priority is controlling pain and inflammation while the stretched and torn soft tissues begin healing. During this phase, you should ice the shoulder every couple of hours for the first day or two, then as needed after that.
Sleep can be tricky. Avoid lying on the affected side entirely. The safest position is on your back or on the opposite side, with a supportive pillow tucked under or beside the injured arm to keep the shoulder in a neutral position. Sleeping slightly reclined (in a recliner or propped up with pillows) is another option that many people find more comfortable in the early days.
Your doctor may recommend gentle range-of-motion exercises even in this early phase, particularly light internal and external rotation work using a resistance band. These aren’t meant to strengthen anything yet. They keep the joint from stiffening and maintain some muscle engagement around the rotator cuff and shoulder blade. Expect to use the sling for a few weeks, depending on your age, activity level, and the severity of the injury.
Weeks Two Through Four: Restoring Range of Motion
Once pain and swelling are under control, rehabilitation shifts toward getting your shoulder moving through a broader range. Exercises in this phase typically target the deltoid, trapezius, and serratus anterior muscles, working the shoulder through horizontal and diagonal movements. Resistance increases compared to the first phase, and you’ll start pushing toward 90 to 150 degrees of overhead motion.
This is the phase where many people make the mistake of thinking they’re fine and abandoning their exercise program. The shoulder may feel functional for everyday tasks, but the stabilizing muscles are still weak, and the ligaments are still healing. Skipping this phase significantly raises the odds of re-dislocation.
Weeks Four Through Six: Strengthening and Endurance
The final rehabilitation stage introduces heavier resistance work, plyometric exercises (quick, explosive movements), and endurance training for the shoulder. The target is full range of motion, around 190 to 200 degrees, with strength that matches your uninjured arm. After this phase, avoid lifting heavy objects for a total of 8 to 12 weeks from the date of injury.
For athletes looking to return to contact sports, the bar is higher. Clinical return-to-sport criteria include full, pain-free passive range of motion, at least 95% of your pre-injury bench press strength, and symmetrical pulling and pushing strength between both arms. Rotator cuff strength is also tested specifically: your external rotators should produce force equal to roughly 18 to 23% of your body weight, and your internal rotators 26 to 32%. These benchmarks exist because returning too early is one of the strongest predictors of re-injury.
Why Recurrence Risk Depends on Your Age
Younger patients face dramatically higher odds of dislocating again. In one long-term study following patients for 25 years after a first dislocation treated without surgery, 72% of those aged 12 to 22 experienced a recurrence. Among patients aged 23 to 29, the rate was 56%. For those over 30, it dropped to 27%. Another study found that within five years, 87% of patients aged 15 to 20 had recurrent instability, compared to 31% of those aged 31 to 35.
The reason is partly anatomical. Younger people tend to have more ligament laxity, and they’re more likely to return to high-demand sports. But the numbers also reflect the nature of the injury itself: a first dislocation often tears the labrum (the cartilage rim of the shoulder socket) or creates a dent in the ball of the upper arm bone. These structural changes make the joint mechanically easier to dislocate again, regardless of how strong the surrounding muscles become.
When Surgery May Be Necessary
Most first-time dislocations are managed without surgery. But certain structural damage changes the calculus. A torn labrum (called a Bankart lesion) that doesn’t heal on its own, a large dent in the humeral head (a Hill-Sachs lesion) that catches on the socket rim, or significant bone loss from the socket edge (more than 20%) are all scenarios where surgical repair produces better long-term outcomes than rehab alone.
For young, active patients, especially males in contact sports, some orthopedic surgeons now recommend surgical stabilization after a first dislocation rather than waiting for recurrence. The logic is straightforward: if the five-year recurrence rate for a 17-year-old is nearly 87%, waiting for a second or third dislocation means allowing further structural damage with each episode. Roughly 38% of patients aged 12 to 25 eventually undergo surgical stabilization at some point anyway.
Risk factors for surgical failure include joint laxity, young age at first dislocation, and the length of time between the first dislocation and surgery. The longer you wait with recurrent instability, the more bone and cartilage erode, making repair more complex.
Long-Term Joint Health
Chronic shoulder instability, whether from repeated dislocations or from a single dislocation that never fully healed, generally leads to degenerative arthritis over time. The cartilage surfaces of the joint wear down unevenly when the ball doesn’t sit centered in the socket. This process can take years or decades, but it’s the predictable endpoint of untreated instability.
Older patients (typically over 40) face a different complication pattern. They’re less likely to dislocate again but more likely to have a rotator cuff tear alongside the dislocation. If a rotator cuff tear is present and goes unrepaired, it leads to progressive weakness and loss of overhead function that rehab alone can’t fully address. This is why imaging after a dislocation in an older patient often includes an MRI, not just X-rays.
The single most protective thing you can do for your shoulder long-term is complete the full rehabilitation protocol, even after the pain is gone and daily activities feel normal. Strong rotator cuff muscles and stable scapular control are the best defense against both re-dislocation and gradual joint deterioration.
