Recurrent Shoulder Dislocation: Why It Keeps Happening and How It Is Treated

Recurrent shoulder dislocation means the ball of the arm bone comes out of the socket more than once. It usually happens because the first dislocation tore the labrum and capsule at the front of the joint and they did not heal back in place. The risk is far higher in young people and athletes, and every new dislocation adds damage to the cartilage and the bone of the socket rim. Rehabilitation works for selected patients, but when dislocations keep recurring, arthroscopic shoulder stabilisation surgery is usually the most effective treatment.

Why does the shoulder keep dislocating?

The shoulder is the body’s most mobile and least stable joint: a large ball sits on a small, shallow socket. What keeps it in place is the “bumper” formed by the labrum around the socket rim, the ligaments and capsule, and the rotator cuff muscles. In a first forward dislocation the labrum is usually torn off the front rim (a Bankart lesion), and the back of the humeral head may be dented (a Hill-Sachs defect). If these do not heal in place, the joint loses its front bumper and comes out again with less force each time.

Risk factors for recurrence

  • Young age: the risk is much higher under 20–25, exceeding half in some studies of young patients.
  • Contact and throwing sports: goalkeeping, handball, basketball, martial arts, swimming.
  • Generalised ligament laxity.
  • A large Hill-Sachs defect or bone loss at the socket rim on imaging.
  • Number of previous dislocations: each one adds damage and makes the next easier.

Symptoms

  • The shoulder comes out with certain movements — raising the arm out and turning it back — or even in sleep.
  • A feeling that the shoulder is about to slip out (apprehension).
  • Pain and weakness after each episode.
  • Avoiding sport or overhead activity for fear of dislocation.
  • Putting the shoulder back yourself — a sign of advanced tissue damage.

The damage from ignoring recurrent dislocation

Each dislocation grinds the front rim of the socket against the humeral head, gradually wearing the bone and enlarging the Hill-Sachs defect; in older patients the rotator cuff may tear. Over time the problem can move from a simple arthroscopic repair to needing a bone procedure such as a Latarjet, and the long-term risk of shoulder arthritis rises.

Full and partial dislocation

In a full dislocation the ball comes completely out and usually needs reduction in hospital. In a partial dislocation (subluxation) it slips out partly and returns by itself, with painful slipping and temporary weakness. Repeated subluxations are a sign of true instability and deserve the same assessment, because the damage to the labrum and capsule can be similar.

Diagnosis

  • Examination: apprehension and relocation tests for anterior instability, and assessment of laxity.
  • X-rays: show Hill-Sachs defects and rim fractures.
  • MRI: shows the torn labrum and capsule.
  • CT: measures bone loss at the socket rim and guides the choice of operation.

Key numbers to know

  • In an analysis of 10 studies (1,324 patients), 39% had recurrent instability after a first anterior dislocation, and the risk was about 13 times higher in people aged 40 or under (Olds et al., BJSM 2015).
  • In randomised trials of first-time dislocation, recurrence was 6.3% after surgical stabilisation versus 46.6% with a sling alone, and 30.8% of non-operative patients later needed surgery (Belk et al., AJSM 2023).
  • Among 124 athletes, recurrence was 1.6% after Latarjet versus 16.1% after arthroscopic Bankart repair, with similar return-to-sport rates (Hurley et al., 2021).
TreatmentWhen we use itWhat to expect
Reduction, sling and rehabilitationA first dislocation in non-athletes or older adultsGradual return of movement while watching for recurrence
Arthroscopic Bankart repairRecurrent dislocation, or a first dislocation in a young athlete with a Bankart tear and minimal bone lossSmall incisions; return to sport in roughly 4–6 months
Bankart with remplissageA large (off-track) Hill-Sachs defect with minimal glenoid bone lossLower recurrence risk without open surgery
Latarjet procedureSignificant glenoid bone loss or a failed Bankart repairThe lowest recurrence rates, especially in contact sports

At Prof. Dr. Ibrahim Shaarawi’s clinics in Nasr City, Mohandeseen and New Cairo (5th Settlement) we test shoulder stability and review your CT and MRI at the same visit, measuring bone loss to choose rehabilitation, Bankart repair or Latarjet.

Treatment: without surgery or with surgery?

OptionUsually suitsNotes
Physiotherapy and strengtheningOlder, less active patients; a single dislocation with good stabilityDoes not reattach the torn labrum but improves muscle control
Arthroscopic BankartRecurrent dislocation without major bone lossLabrum and capsule repaired with anchors and sutures
Bankart with remplissageLarge Hill-Sachs defect with limited bone lossFilling the defect with posterior tendon reduces recurrence
Open LatarjetMajor bone loss or failed previous surgeryRebuilds the rim with a bone block

Treatment without surgery

A rehabilitation programme strengthens the rotator cuff and shoulder-blade muscles and improves control of shoulder position, while avoiding the positions that cause dislocation. It can work for people who avoid high-risk sport, but exercise does not put the torn labrum back, so recurrence remains common in young people. A randomised trial found that early arthroscopic stabilisation after a first dislocation in young patients reduced re-dislocation compared with a sling and rehabilitation.

Recurrent dislocation in athletes

Young athletes in contact or throwing sports are both the most likely to re-dislocate and the most affected by it, since each episode means time off. Some are therefore advised to consider stabilisation after the first dislocation, especially with a clear Bankart lesion on MRI. The decision weighs the season, sporting ambition and examination findings, with the goal of a stable shoulder that can return to play safely.

First aid when the shoulder comes out again

  • Do not force the shoulder back in or let an untrained person try; it can break bone or injure nerves.
  • Support the arm in a sling or scarf and apply wrapped ice.
  • Go to the emergency department for X-rays before and after reduction and a nerve and circulation check.
  • After reduction, book an assessment of the instability rather than just having it put back each time.
SituationUsual approach
Young athlete, first dislocation, Bankart lesion on MRIDiscuss early arthroscopic stabilisation
Young non-athlete, first dislocationRehabilitation and follow-up; surgery if it recurs
Over 40, first dislocationCheck the tendons first; a rotator cuff tear may be the bigger problem
Recurrent dislocation with bone lossUsually a bone procedure such as Latarjet

Frequently asked questions about recurrent shoulder dislocation

What causes recurrent shoulder dislocation?

Usually a torn labrum and capsule at the front of the joint (Bankart lesion) after the first dislocation, with or without a Hill-Sachs defect or socket bone loss.

Can recurrent dislocation be treated without surgery?

Physiotherapy may be enough for older, less active people, but it does not reattach the torn labrum, so recurrence is common in young athletes.

What damage does recurrent dislocation cause?

Wear of the socket rim, a larger Hill-Sachs defect, possible tendon tears and a higher risk of arthritis; treatment can shift from simple arthroscopy to a bone procedure.

When do I need surgery?

When dislocations recur or instability persists despite rehabilitation, or in young athletes at high risk; examination and imaging decide which operation.

How can I reduce the risk of dislocating again?

Keep up cuff and shoulder-blade strengthening, avoid forcing the raised-and-turned-back position, warm up well and do not return to play before strength and confidence recover.
