Purpose: This study was to understand about the measurement of shoulder motion fraction and motion ratio. We proposed the radiological criterior of glenohumeral and scapulothoracic movement ratio.
Materials and Methods : We measured the motion fraction of the glenohumeral and scapulothoracic movement using CR(computed radiological system) of arm elevation at neutral, 90 degree, full elevation. Central ray was to the cephald for the parallel scapular spine, and the tilting of torso was external oblique for perpendicular to glenohumeral surface. Healthful donor of 100 was divided 5 groups by age(20, 30, 40, 50, 60). The angle of glenohumeral motion and scapulothoracic motion could be taken from gross arm angle and radiological arm angle. We acquired 3 images at neutral, and full elevation position and measured radiographic angle of glenoheumeral, scapulothoracic movement respectively.
Results: While the arm elevation was , the shoulder motion fraction was 1.22(M), 1.70(W) in right arm and 1.31, 1.54 in left. In full elevation, Right arm fraction was 1.63, 1.84, and left was 1.57, 1.32. In right dominant arm(78%), and Full motion fraction was 1.58, 1.43, in left(22%) 1.82, 1.94. In generation 20, and Full motion fraction was 1.56, 1.52, 30’ was 1.82, 1.43, 40’ was 1.23, 1.16, 50’ was 1.80, 1.28, 60’ was 1.24, 1.75. There was not significantly by gender, dominant arm and age.
Conclusion: The criterior of motion fraction was useful reference for clinical dignosis the shoulder instability.
