Shoulder Dislocation: First-Time vs Recurrent Treatment

A shoulder dislocation is one of the most painful orthopedic emergencies — the ball of the shoulder pops fully out of the socket, usually anteriorly and inferiorly. The shoulder has the largest range of motion of any joint in the body, and that mobility comes at the cost of stability. The right treatment for a shoulder dislocation depends heavily on whether it is a first event or a recurrent one, the patient’s age, and the demands they place on the shoulder. This article explains the modern approach to both scenarios.

What happens during a dislocation

In most dislocations, the labrum — the ring of fibrocartilage around the rim of the socket — is detached from the front of the socket. This injury is called a Bankart lesion. Often there is also a dent on the back of the humeral head where it impacted against the rim of the socket — a Hill-Sachs lesion. These structural changes mean the shoulder is no longer as stable as it was before the first dislocation, even after the joint is put back in place.

First-time dislocation in a young athlete

A young athlete (under 25, particularly under 20) who has a first traumatic anterior dislocation faces a stark statistic: the recurrence rate is over 80% if managed non-surgically. The labral injury rarely heals well enough to restore full stability, and most return-to-sport attempts end with another dislocation, often during the first season back. For this group, modern practice increasingly favours early arthroscopic stabilisation after the first event rather than waiting for recurrence. Each subsequent dislocation worsens the structural damage and makes a later operation more difficult.

First-time dislocation in older adults

In a patient over 40, a first dislocation has a different profile. Recurrence rates are lower (around 20–30%), but a rotator cuff tear is much more likely as part of the injury. Imaging — MRI in addition to X-ray — is essential. Many older patients are managed non-surgically initially with sling, physiotherapy, and observation; cuff tears that contribute to instability are addressed surgically as needed.

Recurrent dislocation

Once a shoulder has dislocated more than once or twice, surgical stabilisation is almost always recommended regardless of age. Each dislocation is painful, often happens in low-demand situations (rolling over in bed, reaching for a top shelf), and progressively damages the joint surfaces, predisposing to later arthritis.

Surgical options

Two operations dominate modern practice:

Arthroscopic Bankart repair

The standard operation. Suture anchors are used to reattach the labrum to the rim of the socket through small portals. Day-care procedure under general anaesthesia. Sling for 4–6 weeks; full sport at 4–6 months. Excellent outcomes (>90% return to sport) in patients without significant bone loss.

Latarjet procedure

For patients with significant bone loss (a large Hill-Sachs lesion, or erosion of the front rim of the socket from multiple dislocations), the coracoid process — a small piece of bone with attached muscle — is transferred to the front of the socket. This restores stability through a combination of bone block effect and dynamic sling effect. Open or arthroscopic. Recovery slightly longer than Bankart repair. Lower recurrence rate in high-risk patients.

Recovery

After Bankart repair, the typical pathway is sling for 4–6 weeks, gentle range starting at week one, active range from week six, strengthening from week twelve, and return to contact sport at 4–6 months after passing functional testing. Latarjet recovery is broadly similar with a slightly slower start.

Reducing the chance of re-dislocation

After stabilisation, ongoing rotator cuff strengthening, scapular stability training, and sport-specific neuromuscular work all reduce recurrence risk. For collision sports, the use of a stabilisation brace during play for the first season back is sometimes recommended.

What not to do

Two things commonly go wrong. First, leaving a first dislocation in a young athlete untreated and hoping for the best — this almost always leads to recurrence and worse damage. Second, attempting to reduce a dislocation at home — this can fracture the bone and damage nerves; reduction should be performed in a hospital setting with appropriate analgesia and post-reduction imaging.
