A shoulder dislocation rarely happens in isolation. When the shoulder pops out of its socket, the force involved can damage the surrounding structures, leaving a range of secondary injuries in its wake. These secondary injuries affect the stability and function of the joint, and they are a big reason why proper rehabilitation after a shoulder dislocation matters so much. Understanding what can be injured alongside the dislocation helps explain why recovery is about far more than putting the joint back in place.
Why Shoulder Dislocations Cause Secondary Injuries
The shoulder is the most mobile joint in the body, which is exactly what makes it prone to dislocating. That same mobility means the ball of the joint can be forced out of its shallow socket with considerable force, and in the process it can damage the cartilage, tendons, ligaments and bone around it. These secondary injuries are common, and they often explain why a shoulder feels unstable, weak or painful long after the dislocation itself. Recognising them is the first step to a full recovery.
Bankart Lesions
A Bankart lesion is one of the most common secondary injuries after a shoulder dislocation. It involves a tear or detachment of the labrum, the ring of cartilage that surrounds the socket and helps keep the joint stable. When the labrum is damaged, the shoulder loses some of its ability to stay properly aligned, which raises the risk of the joint dislocating again and reduces stability.
Hill-Sachs Lesions
A Hill-Sachs lesion is a dent or compression injury to the ball of the upper arm bone, caused when it presses hard against the edge of the socket during the dislocation. Larger lesions can affect how smoothly the joint moves and can contribute to ongoing instability and repeat dislocations. Bankart and Hill-Sachs lesions frequently occur together as a combined injury.
Rotator Cuff Tears
The rotator cuff is a group of muscles and tendons that control and stabilise the shoulder. A dislocation can place these tendons under sudden, high stress, leading to partial or complete tears. This is more common in older adults, and it can weaken the shoulder, reduce function and add to joint instability if not addressed.
Labral Tears
Beyond the specific Bankart lesion, the labrum can be torn or irritated in other areas during a dislocation. Because the labrum deepens the socket and adds stability, any tear can compromise how secure the joint feels and increase the chance of future dislocations. A labral injury is a frequent finding after a shoulder comes out of its socket.
Glenohumeral Ligament Sprains
The glenohumeral ligaments are strong bands that help hold the shoulder in place. A dislocation can stretch or tear these ligaments, reducing the passive support they provide and leaving the joint feeling loose or unstable. Restoring their function and stability through targeted rehabilitation is an important part of recovery.
Rehabilitation After a Shoulder Dislocation
Good rehabilitation addresses both the dislocation and any secondary injuries present, because treating one without the other rarely gives a lasting result. Physiotherapy focuses on restoring strength, range of motion and stability, tailored to the specific structures involved. That usually means rotator cuff and scapular strengthening, progressive range-of-motion work, and proprioceptive or balance training to rebuild the joint’s sense of position. Hands-on treatment can help with pain and movement along the way. The aim is not just to settle the current injury, but to reduce the risk of it happening again. A structured plan through return to sport conditioning helps bridge the gap back to full activity.
Common Questions
How Common Are Secondary Injuries After a Shoulder Dislocation?
They are very common. Labral injuries such as Bankart lesions and bony Hill-Sachs lesions occur in a large proportion of first-time dislocations, and the likelihood of associated damage rises with each repeat dislocation. This is why a thorough assessment is important.
Do I Need Surgery for a Bankart or Hill-Sachs Lesion?
Not always. Many people manage well with rehabilitation, while others, particularly younger athletes or those with recurrent dislocations, may be advised to consider surgery. The decision depends on the injury and your goals, and is made with a surgeon and physiotherapist.
Can Physiotherapy Prevent Another Shoulder Dislocation?
Physiotherapy cannot guarantee it, but building strength, control and stability around the shoulder can meaningfully reduce the risk of recurrence. A tailored programme is one of the most effective ways to protect the joint going forward.
How Long Is Recovery After a Shoulder Dislocation?
It varies with the severity of the dislocation, the secondary injuries involved and whether surgery is needed. Simpler cases may settle over a few months, while more complex injuries take longer. Your physiotherapist can give you a clearer timeframe after assessment.
How BeFit Can Help
At BeFit Training Physiotherapy, our physiotherapists assess and rehabilitate shoulder dislocations and their secondary injuries at our Edgecliff and Coogee clinics. We identify which structures are involved, build a programme to restore strength, movement and stability, and work to lower the risk of the shoulder dislocating again. Every initial consultation runs for forty-five minutes, one-on-one, with a thorough assessment and a clear explanation of what we find. Our sports physiotherapy team supports you from injury through to return, and no referral is required to book.
