Key result
Adolescent patients under 25 years old with recurrent shoulder dislocation had a significantly higher rate of glenoid off-track compared to adult patients (63.6% vs 37.8%, p=0.027).
Why the study?
Young age is the most important risk factor for recurrent shoulder dislocation, and glenoid off-track is claimed to increase recurrence and treatment failure risk, prompting evaluation of whether younger patients have higher off-track rates.
Do adolescent patients with recurrent shoulder dislocation have a higher rate of glenoid off-track compared to adult patients?
Cross-Sectional (n=70)
Do adolescent patients with recurrent shoulder dislocation have a higher rate of glenoid off-track compared to adult patients?
Absolute Event Rate: 63.6% vs 37.8%
p-value: p=0.027
Adolescent patients with recurrent shoulder dislocation have a significantly higher rate of glenoid off-track lesions compared to adults, which may explain their higher risk of recurrence and treatment failure.
Findings do not support higher glenoid off-track rates in younger patients; leaves open its role in age-related recurrence risk.
Background: Shoulders instability and anterior shoulder dislocation is a common problem in adolescents especially athletes and military personnel.Young age is known as most important risk factor of recurrent shoulder dislocation.The concept of "glenoid off-track" claimed to increase risk of shoulder dislocation and failure of treatment so we hypothesized that younger patients with recurrent shoulder dislocation have more rate of glenoid off-track than adult patients.Material and Method: 70 patients including military personnel referred with recurrent shoulder dislocation chose and 3D CT-scan of affected shoulder obtained.Then the expected glenoid diameter, glenoid defect and the Hill-Sachs lesion size measured and patients grouped as glenoid off-track or on-track.All these measurements and being off-track/on-track compared between adults (>25 years old) and adolescents (<25 years old). Results:The mean size of expected glenoid diameter, glenoid defect and Hill-Sachs lesion show no significant difference between adolescent and adult groups, however glenoid off-track cases are significantly more in adolescent group compared to adult group (63.6% vs 37.8% p-value:0.027CI:95%).Conclusion: Younger patients have significantly more rate of glenoid off-track compared to adult group, which could be the reason of higher rate of recurrent shoulder dislocation and treatment failure in this group of age.

A 2022 study conducted a cross-sectional in Recurrent anterior shoulder dislocation (n=70). Adolescent age (<25 years) vs. Adult age (≥25 years) was evaluated on Glenoid off-track rate (p=0.027). Adolescent patients under 25 years old with recurrent shoulder dislocation had a significantly higher rate of glenoid off-track compared to adult patients (63.6% vs 37.8%, p=0.027).
