Treatment Options for Shoulder Separation in Pediatric Patients
For pediatric shoulder separations (acromioclavicular joint injuries), treatment should be primarily conservative with immobilization and rehabilitation for most cases, reserving surgical intervention only for severe dislocations (Rockwood types IV-VI) or cases with persistent symptoms despite conservative management.
Classification and Initial Assessment
- Shoulder separations (acromioclavicular injuries) in children are classified using the Rockwood system:
- Type I: Sprain of AC ligaments without displacement
- Type II: AC ligament tear with minimal displacement
- Type III: Complete tear of AC and coracoclavicular ligaments with 25-100% displacement
- Types IV-VI: Severe displacements with various directional components
Treatment Algorithm by Classification
Type I and II Injuries (Mild to Moderate)
- Conservative management is the standard of care:
- Immobilization with a sling or posterior splint for 1-3 weeks 1
- Pain control with appropriate pediatric dosing of analgesics
- Early mobilization after acute pain subsides (typically within 1-2 weeks)
- Progressive rehabilitation focusing on range of motion and strengthening
Type III Injuries (Moderate to Severe)
- Initial conservative management recommended:
Type IV-VI Injuries (Severe)
- Surgical consultation recommended:
- Referral to pediatric orthopedic surgeon or pediatric surgeon with appropriate training 4
- Surgical repair typically indicated for these severe displacements
- Post-surgical rehabilitation protocol determined by surgeon
Rehabilitation Protocol
Acute Phase (0-2 weeks):
- Immobilization with sling
- Ice for pain and swelling control
- Gentle pendulum exercises after first week if pain allows
Intermediate Phase (2-6 weeks):
- Progressive range of motion exercises
- Isometric strengthening exercises
- Continued protection from contact sports
Advanced Phase (6+ weeks):
- Progressive resistance exercises
- Sport-specific or activity-specific training
- Return to full activities when:
- Full pain-free range of motion achieved
- Normal strength compared to unaffected side
- Functional testing demonstrates readiness
Special Considerations for Pediatric Patients
- Growth plate considerations: Children with open growth plates require careful monitoring to prevent growth disturbances
- Age-appropriate rehabilitation: Exercises should be tailored to child's developmental level
- Return to play decisions: More conservative approach recommended for younger patients
Follow-up and Monitoring
- Initial follow-up within 1-2 weeks of injury
- Radiographic evaluation at 6-8 weeks to assess healing
- Long-term follow-up recommended for severe injuries to monitor for:
- Growth disturbances
- Development of degenerative changes 2
- Persistent "step deformity" which may be cosmetic but functionally acceptable
Outcomes and Prognosis
- Excellent outcomes typically seen with conservative management for Type I-III injuries 2
- Most pediatric patients return to full activities without limitations
- Cosmetic deformity (visible "step" at the AC joint) may persist but is rarely functionally limiting
- Long-term studies show minimal functional deficits at 10-year follow-up even with persistent deformity 2
Pitfalls and Caveats
- Avoid prolonged immobilization beyond 3-4 weeks as this may lead to shoulder stiffness
- Don't confuse shoulder separation (AC joint injury) with shoulder dislocation (glenohumeral joint injury), which requires different management
- Beware of missed associated injuries (clavicle fractures, rotator cuff injuries)
- Surgical intervention in pediatric patients carries risks of growth disturbance and should be reserved for severe cases
The conservative approach to pediatric shoulder separations is supported by evidence showing excellent functional outcomes with non-operative management, even in cases where cosmetic deformity persists 2, 3.
