14. Arthrokinematics Convex- Concave Rule Concave- Convex Rule
Fixed Concave Surface, Moving Convex Surface
Glide occurs in opposite direction
Concave- Convex Rule
Fixed Convex Surface, Moving Concave Surface
Glide occurs in same direction

15. Arthrokinematics

16. Arthrokinematics Glenohumeral Joint
Convex on Concave
Glide in opposite direction to Roll
Flexion
Humerus rolls anteriorly and glides posteriorly
Abduction
Humerus rolls superiorly and glides inferiorly
Ignore external and internal rotation as the rules do not apply here

17. Arthrokinematics
As humerus rotate the capsule acts like a hammock and swings
During external rotation the humeral head begins to glide anteriorly, capsule tightness up and pull humeral head posteriorly

18. Arthrokinematics
If anterior inferior aspect of the capsule is lax it doesn’t restrict humeral head motion
Therefore no posterior glide occurs
Anterior dislocation can occur
Tightening of posterior capsule
