Key Takeaway
Adolescents aged 14–18 carry the highest dislocation risk and recurrence rates sufficient to justify early arthroscopic stabilization, while children under 12 are best managed conservatively given ligamentous-to-bone strength ratios.

Summary
This narrative review categorizes pediatric shoulder instability by developmental stage, proposes a diagnostic algorithm, and summarizes management strategies across anterior, posterior, multidirectional, and functional instability subtypes. Anterior dislocation in patients under 12 is managed conservatively; adolescents aged 12–16 face high recurrence risk warranting early arthroscopic Bankart repair. Significant glenoid bone loss in this population triggers consideration of Latarjet or iliac crest bone grafting, and functional posterior instability is highlighted as frequently misdiagnosed and responsive to neuromuscular electrical stimulation.
Key Limitation
As a narrative review without systematic search methodology or meta-analytic pooling, conclusions on recurrence rates and surgical timing thresholds are not quantitatively supported and reflect expert synthesis rather than aggregated evidence.
Original Abstract
ABSTRACT
Shoulder instability is increasingly prevalent among pediatric and adolescent populations due to growing participation in competitive sports at younger ages. However, the literature remains challenging to apply clinically, as it often fails to distinguish between different developmental stages, leading to potential overtreatment or undertreatment. This review aims to categorize types of shoulder instability in young patients, propose a diagnostic approach, and summarize current management strategies based on available evidence. Shoulder dislocations are rare in skeletally immature patients, with the highest risk observed in those aged 14–18 years. Younger children, particularly those under ten, are less prone to dislocations due to the relative strength of their ligaments compared to bone. Diagnosis relies on history, physical examination, and imaging modalities such as radiographs, computed tomography (CT), and magnetic resonance imaging (MRI). Special attention is required for functional posterior instability, which is frequently misdiagnosed. Treatment decisions—whether conservative or surgical—remain controversial. Conservative management, including immobilization and rehabilitation, is the first-line approach for primary anterior dislocations, particularly in children under 12. However, adolescents aged 12–16 face a high risk of recurrence, making early surgical stabilization a viable option. Arthroscopic stabilization is the preferred surgical technique, especially for athletes. In cases of recurrent instability with significant glenoid bone loss, the Latarjet procedure or iliac crest bone grafting may be indicated. Posterior instability, though rare, follows treatment principles similar to those in adults, with a primary emphasis on rehabilitation. Functional posterior instability responds well to neuromuscular electrical stimulation. Multidirectional instability, often associated with ligamentous laxity, is primarily managed nonoperatively, but surgical stabilization may be necessary if symptoms persist. In conclusion, pediatric shoulder instability is complex and requires an individualized approach. Understanding age-specific anatomical and physiological differences is crucial for optimizing treatment outcomes and preventing long-term complications.
