剛体バネモデルによるLoose Shoulderの力学的検討
Preserved Fulltext
The purpose of this study is to define the mechanical cause of the loose shoulder by using a twodimensional rigid body spring model. Mechanical models of the glenohumeral joint were formulated based on radiographic studies of normal shoulders and loose shoulders. In 0 degree of abduction the mechanical stress of the lower end of the glenoid increased and the humeral head shifted to the inferomedial direction. In 30 to 90 degrees of abduction, the results of
