Clinical Report: Shoulder Instability in Children: Epidemiology, Diagnosis, and Management
Overview
Shoulder instability in children aged 5 to 14 years is relatively rare but increasing due to early sports participation. Diagnosis relies on detailed history, physical examination, and imaging, while management balances conservative and surgical approaches, with recent evidence supporting early surgery to reduce recurrence.
Background
Shoulder instability in the pediatric population is challenging to study due to variations in skeletal maturity and age ranges. Children with open growth plates are more prone to physeal or metaphyseal fractures rather than ligamentous injuries. Most data are extrapolated from adults, which may lead to inappropriate treatment. Understanding the epidemiology, clinical presentation, and management specific to children is essential for optimal care.

14 times higher than open physis
Key Findings
Shoulder dislocations are rare in children under 10 years, comprising only 2% of traumatic dislocations.
Children with open growth plates tend to sustain fractures rather than ligamentous injuries due to stronger ligaments relative to bone.
Physical examination includes specific tests for anterior and posterior instability and assessment of ligamentous laxity and neurological status.
Imaging with radiographs, CT, and MRI is essential, with MRI preferred to avoid radiation and to assess soft tissue injuries.
Conservative treatment with immobilization and rehabilitation is standard for first-time anterior dislocations, but recurrence rates vary from 6% to 33%.
Recent evidence suggests early surgical intervention may reduce recurrence and improve outcomes in pediatric shoulder instability.
Clinical Implications
Clinicians should carefully evaluate pediatric shoulder instability with age-appropriate diagnostic tests and imaging, considering skeletal maturity. Conservative management remains first-line for initial dislocations, but early surgical referral should be considered in recurrent cases or high-risk patients to prevent further instability and functional impairment.
Conclusion
Shoulder instability in children requires tailored diagnosis and management strategies distinct from adults. Early recognition and appropriate treatment can improve outcomes and reduce recurrence in this vulnerable population.
