Recurrent instability following shoulder dislocation in patients aged 14 years or younger is relatively high, with a portion of patients requiring surgical intervention. Shoulder dislocation is not a benign event and requires close attention.
Background: The natural history of traumatic glenohumeral dislocation is well-established in young adults, but it is less clear in pediatric patients. We aimed to determine the rate of recurrent instability and medium-term functional outcome following shoulder dislocation in patients aged 14 years or younger. Methods: All patients aged 14 years or younger who sustained a glenohumeral dislocation from 2008 to 2019 presenting to our regional health-board were identified. Patients who had subluxations associated with generalized laxity were excluded. Data was collected regarding further dislocations, stabilization surgery, sporting activity and patient-reported outcomes using the Western Ontario Shoulder Instability (WOSI) Index and Quick Disabilities of the Arm, Shoulder, and Hand score. Results: Forty-one patients with a radiologically confirmed traumatic glenohumeral dislocation were suitable for study inclusion [mean age at injury 12.3 y (range: 7.2 to 14.0 y), male sex 29 (70.7%), median 7.9 y follow-up]. The incidence rate of pediatric glenohumeral dislocation was 2.5 cases per 100,000 population (aged 0 to 14 y) per year. Recurrent dislocation occurred in 43.9% (n=18/41) at a median time of 14.7 months postinjury (range: 1 to 54 mo). Skeletal maturity was associated with significantly higher proportion of recurrent instability (immature 6/24 vs. mature 12/17, P=0.01). One in 5 patients required surgical intervention for recurrent instability [mean 8 (range: 1 to 14) dislocations before surgery]. Twenty-eight patients had completed outcome questionnaires. The median modified WOSI score was 87.1% [270 (interquartile range: 65 to 795)] and the median Quick Disabilities of the Arm, Shoulder, and Hand score was 3.4 (interquartile range: 0 to 9.7). Recurrent shoulder instability was significantly associated with poorer WOSI score (unstable 71.4% vs. stable 94.3%, 95% confidence interval of the difference 6.2-36.9, P=0.04). Conclusions: Traumatic glenohumeral dislocation in patients aged 14 years or younger occurs rarely but is not a benign event. One in 2 patients experienced recurrent dislocation and 1 in 5 ultimately underwent surgical stabilization.
