Abstract

Introduction:
In our study, the
aim was to assess the glenoid with glenopolar angle (GPA) measurements in cases
with anterior shoulder dislocation and a control group.

Methods: This comparative, retrospective radiologic study
compared the GPA measured on direct radiographs of patients with shoulder
dislocation (Group 1) with a control group (Group 2).

Results: The GPA in Group 1 was observed to be 32.34⁰ (std.
dev. 1.96), while it was 34.50⁰ (std. dev. 2.32) in Group 2 {significant
difference was observed as p<0.001 (p<0.05)}.

Conclusion: The results of this study show the GPA of patients
with anterior shoulder dislocation was significantly lower compared to a
control group. Glenoid alignment is a possible risk factor for anterior
shoulder dislocation and should be considered during assessment and management
of these cases.
