Clinical Scorecard: Shoulder Instability in Children: Overview of Epidemiology, Causes, Diagnosis, and Management

At a Glance

Key Highlights

• Shoulder dislocations are rare in children under 10 years; incidence increases significantly in adolescents with closed physes.
• Ligaments in young children are stronger than bone, making fractures more common than ligamentous injuries.
• Early surgical intervention may reduce recurrence rates compared to traditional conservative management.

Guideline-Based Recommendations

Diagnosis

• Perform thorough history focusing on pain, injury mechanism, prior instability, and family history of connective tissue disorders.
• Use physical examination tests: anterior load and shift, anterior apprehension, relocation sign for anterior instability; Jerk, Kim, push–pull tests for posterior instability.
• Assess capsular laxity and hypermobility with Beighton score, Sulcus and Gagey signs.
• Evaluate neurological status and muscular imbalances including scapulothoracic motion and rotator cuff strength.
• Refer to pediatric neurology if instability may be seizure-related.

Management

• Initial management of first-time anterior dislocation is conservative with sling immobilization followed by physical therapy.
• Consider early surgical intervention in recurrent or high-risk cases to reduce redislocation rates.
• Balance use of CT imaging against radiation risks; prefer MRI for soft tissue assessment without radiation.
• Radiographs should be obtained prior to reduction to assess for physeal fractures in patients with open physes.

Monitoring & Follow-up

• Monitor for recurrence of instability, functional outcomes, and return to sport.
• Assess ongoing apprehension or dissatisfaction after conservative treatment.
• Follow-up imaging as needed to evaluate healing and joint integrity.

Risks

• Higher risk of redislocation in adolescents with closed physes compared to younger children.
• Potential for physeal or metaphyseal fractures rather than ligamentous injury in skeletally immature patients.
• Radiation exposure from CT imaging in pediatric population.

Patient & Prescribing Data

Pediatric patients aged 5-14 years with shoulder instability and open growth plates

Conservative treatment is standard for first-time dislocations with good outcomes; however, recurrence rates vary and early surgery may be beneficial in select cases.

Clinical Best Practices

• Differentiate between age groups and skeletal maturity when diagnosing and managing shoulder instability.
• Use a combination of history, physical examination, and imaging tailored to pediatric anatomy and physiology.
• Incorporate assessment of ligamentous laxity and neuromuscular control in evaluation.
• Prefer MRI over CT to minimize radiation exposure in children.
• Consider multidisciplinary approach including pediatric neurology for seizure-related instability.
• Educate patients and families about risks of recurrence and treatment options.
