Shoulder Dislocation: Treatment and Recovery Timeline

What happens during a shoulder dislocation?

The shoulder joint is the most mobile joint in the body and, consequently, the most commonly dislocated. In an anterior dislocation — by far the most common type, accounting for roughly 95% of cases — the humeral head (ball) shifts forward and out of the glenoid socket, typically from a fall on an outstretched arm or a direct blow with the arm raised.

The dislocation tears or stretches the labrum (a ring of cartilage that deepens the socket) and the joint capsule. The most common structural injury is a Bankart lesion — a tear of the anterior-inferior labrum — which is present in the majority of traumatic anterior dislocations and is the primary anatomical reason for recurrence.

A posterior dislocation — where the ball shifts backward — is much less common, often associated with seizures or electrical injury, and can be subtle to diagnose.

A dislocated shoulder can also injure nearby structures: the rotator cuff (more common in older adults 3Ref 3American Academy of Orthopaedic Surgeons (2019).Management of Rotator Cuff Injuries: Evidence-Based Clinical Practice Guideline.Rotator cuff tears as a concurrent injury in shoulder dislocations — particularly in older adults — and the evidence basis for structured physical therapy before surgical consideration), the axillary nerve (causing numbness over the outer shoulder), and rarely the axillary artery.

What is the immediate treatment for a dislocated shoulder?

Go to an emergency department. A dislocated shoulder should not be self-reduced without training and imaging — nerve and vascular injuries need to be assessed, and X-rays rule out associated fractures before manipulation.

In the ED: 1. X-rays confirm the direction of dislocation and identify fractures 2. Reduction — the clinician uses one of several techniques (Cunningham, FARES, Milch, or external rotation methods) to guide the ball back into the socket, usually with pain relief or sedation 3. Post-reduction X-ray confirms successful repositioning 4. Neurovascular check — sensation and pulse assessed before and after 5. Sling applied for initial immobilization

What is the recovery timeline after a shoulder dislocation?

Return to contact sport typically takes at least 12–16 weeks after a first dislocation, provided strength and stability criteria are met — criteria-based clearance is more predictive of safe return than time alone. Everything before that point varies by the person's age, direction of dislocation, associated injuries, and activity demands:

Weeks 1–3: Immobilization phase - Sling use for 1–3 weeks (duration varies; longer in younger high-risk patients) - Pendulum exercises to prevent stiffness - Pain and swelling management

Weeks 3–8: Active rehabilitation phase - Formal physical therapy begins: range of motion restoration, then scapular stabilization, then rotator cuff strengthening - No contact sports or overhead loading

Weeks 8–16: Strengthening and sport-specific phase - Progressive strengthening of shoulder external rotators and periscapular muscles - Sport-specific drills if cleared by the treating clinician

What is the risk of a repeat dislocation?

Recurrence risk is strongly associated with age at first dislocation. Non-operative treatment is associated with a recurrence rate of approximately 55% at more than 10 years of follow-up across the pooled evidence 1Ref 1van Spanning SH, Verweij LPE, Priester-Vink S, van Deurzen DFP, van den Bekerom MPJ (2021).Operative Versus Nonoperative Treatment Following First-Time Anterior Shoulder Dislocation: A Systematic Review and Meta-Analysis.Early operative stabilization (Bankart repair) reduces long-term recurrence to ~10% vs ~55% with non-operative treatment at >10 years follow-up — high-quality evidence supporting surgery discussion in young athletes after first dislocation. Rates are highest in young athletes under 25 who participate in contact or throwing sports.

The Bankart labral tear that typically occurs with the first dislocation is the primary structural reason for recurrence; once torn, the labrum does not reliably heal with immobilization alone.

Because of this, an orthopedic surgeon may discuss early surgical stabilization (Bankart repair) after a first traumatic dislocation in a young athlete who plans to return to high-demand sport. Early surgery reduces long-term recurrence to approximately 10% in the best comparative studies 1Ref 1van Spanning SH, Verweij LPE, Priester-Vink S, van Deurzen DFP, van den Bekerom MPJ (2021).Operative Versus Nonoperative Treatment Following First-Time Anterior Shoulder Dislocation: A Systematic Review and Meta-Analysis.Early operative stabilization (Bankart repair) reduces long-term recurrence to ~10% vs ~55% with non-operative treatment at >10 years follow-up — high-quality evidence supporting surgery discussion in young athletes after first dislocation. This is a genuine shared-decision situation — the evidence for early surgery in young athletes is different from the evidence in older or lower-demand patients.

When is surgery recommended for shoulder dislocation?

Surgery (typically arthroscopic Bankart repair, or Latarjet procedure for cases with significant bone loss) is more commonly recommended when:

• The patient is a young athlete returning to contact or overhead sport with a documented Bankart tear 1Ref 1van Spanning SH, Verweij LPE, Priester-Vink S, van Deurzen DFP, van den Bekerom MPJ (2021).Operative Versus Nonoperative Treatment Following First-Time Anterior Shoulder Dislocation: A Systematic Review and Meta-Analysis.Early operative stabilization (Bankart repair) reduces long-term recurrence to ~10% vs ~55% with non-operative treatment at >10 years follow-up — high-quality evidence supporting surgery discussion in young athletes after first dislocation
• There have been two or more recurrent dislocations
• Associated injuries are present — a large Hill-Sachs lesion (compression fracture of the ball), significant glenoid bone loss, or a rotator cuff tear 3Ref 3American Academy of Orthopaedic Surgeons (2019).Management of Rotator Cuff Injuries: Evidence-Based Clinical Practice Guideline.Rotator cuff tears as a concurrent injury in shoulder dislocations — particularly in older adults — and the evidence basis for structured physical therapy before surgical consideration
• Conservative care and rehab have not prevented recurrence

For older adults with a first dislocation and lower activity demands, a structured conservative program is often successful and surgery is less commonly needed. Even after Bankart repair, long-term follow-up studies show some ongoing recurrence rate and about 14% of patients may need revision surgery 2Ref 2Owens BD, DeBerardino TM, Nelson BJ, Thurman J, Cameron KL, Taylor DC, Uhorchak JM, Arciero RA (2009).Long-term follow-up of acute arthroscopic Bankart repair for initial anterior shoulder dislocations in young athletes.Long-term outcomes of arthroscopic Bankart repair in young athletes (mean 11.7-year follow-up): excellent subjective function but 14.3% redislocation and 21.4% subluxation rates highlight ongoing recurrence risk even after repair.

Who manages shoulder dislocation care?

• Emergency physician — initial reduction and assessment
• Orthopedic surgeon — structural evaluation, surgical decision, follow-up if recurrence is a concern
• Physical therapist — the rehabilitation program, which is essential regardless of whether surgery occurs
