What is the recommended technique for reducing a dislocated elbow, including assessment, analgesia, sedation, traction method, and post‑reduction care?

Elbow Dislocation Reduction Technique

For a dislocated elbow, perform closed reduction using traction-countertraction technique under procedural sedation, followed by immediate active range of motion without immobilization to optimize functional outcomes.

Pre-Reduction Assessment

Imaging

• Obtain plain radiographs first to confirm dislocation and identify associated fractures 1
• Standard AP and lateral views are sufficient for initial assessment
• Post-reduction radiographs are mandatory to confirm adequate reduction and rule out occult fractures

Neurovascular Examination

• Document median, radial, and ulnar nerve function before reduction
• Assess brachial artery pulse and capillary refill
• Median nerve injury is common and typically resolves after reduction 2

Analgesia and Sedation

Use procedural sedation and analgesia (PSA) for reduction 3. While intra-articular anesthesia has been studied for shoulder dislocations, the standard for elbow reduction remains PSA, which provides:

• Adequate muscle relaxation for successful reduction
• Patient comfort during manipulation
• Ability to assess stability post-reduction

Reduction Technique

Traction-Countertraction Method (Primary Technique)

This is the most commonly employed and successful approach 3:

1. Patient positioning: Supine on stretcher
2. Assistant provides countertraction: Grasps upper arm proximal to elbow
3. Physician applies steady longitudinal traction: Pull on forearm with elbow in slight flexion (20-30 degrees)
4. Gentle anterior pressure on olecranon while maintaining traction
5. Avoid hyperextension during reduction maneuver

Alternative Techniques if Initial Attempt Fails 3:

• Patient-assisted countertraction: Patient's body weight provides countertraction
• Leverage approach: Using physician's hands as fulcrum
• Modified Stimson technique: Prone positioning with hanging weight

Common pitfall: Attempting reduction with inadequate sedation leads to muscle spasm and failed reduction attempts.

Post-Reduction Management

Immediate Post-Reduction Care

• Confirm reduction with radiographs 1, 2
• Reassess neurovascular status
• Test stability under fluoroscopy if available to guide treatment 1:
  • <10° joint widening = slight instability (conservative treatment)

  • 10° widening = moderate instability (may need surgical consultation)

  • Frank redislocation = gross instability (requires surgical fixation)

Immobilization Strategy

The evidence strongly favors early mobilization over prolonged immobilization 4, 5, 6:

• No immobilization or minimal splinting (0-3 days maximum) for simple dislocations
• Begin immediate active range of motion under supervision 4
• This approach achieves:
  • Final range of motion within 19 days on average
  • Extension within 5° of contralateral side
  • Excellent functional outcomes 4

Avoid prolonged immobilization (>1 week), which increases risk of:

• Elbow stiffness
• Delayed return to function
• Heterotopic ossification 6

Rehabilitation Protocol 4

• Start active ROM immediately (within 24-48 hours)
• No slings or splints after initial 1-3 days
• Close supervision during early mobilization phase
• Avoid passive stretching initially
• Progress to strengthening at 2-3 weeks

Complications to Monitor

• Recurrent instability: Rare in simple dislocations (<5%) 5
• Persistent stiffness: More common with delayed mobilization
• Heterotopic ossification: Risk increases with prolonged immobilization 2, 6
• Nerve injury: Usually resolves spontaneously after reduction 2
• Associated fractures: Coronoid, radial head, or olecranon fractures may require surgical intervention 1, 2

When to Consider Surgical Referral

• Gross instability on stress testing (frank redislocation) 1
• Complex dislocations with significant fracture fragments 2
• Persistent instability after 2-3 weeks of conservative treatment 5
• Irreducible dislocation after multiple closed attempts

Critical distinction: Simple elbow dislocations (no significant fractures) have excellent outcomes with closed reduction and immediate mobilization 5, 6. Complex dislocations with fractures frequently require surgical intervention for optimal stability 2.
