Abstract:
Objective To assess the relationship between anterior-inferior glenohumeral instability and glenoid version.Methods Both shoulders in 24 patients with unilateral anterior-inferior glenohumeral instability were scanned with multiplanar spiral CT scanner(MSCT).The scapula and the humerus were reconstructed by the volume rendering technique and multiplanar reformation in 4 slices on axial plane from glenoid top to its bottom.The scapular glenoid version angles of 24 patients were measured bilaterally in 4 levels,and compared bilaterally by statistic analysis.Results From the top to the bottom,the scapular glenoid version angle in the side with anterior-inferior glenohumeral instability was respectively(-15.24?10.18)?,(-8.22?8.47)?,(-2.88?4.56)? and(-2.49?6.43)?,while the angle in the healthy side was respectively(-15.07?12.11)?,(-10.63?7.25)?,(-6.04?3.61)? and(-5.26?3.02)?.Only the difference at the 4th plane was significant between the healthy side and the affected side(P
