30 Οκτ 2023 · Individually, each muscle has its own pulling axis that results in a certain movement (prime mover), while together they create a concavity compression. This is a stabilizing mechanism in which compression of the humerus into the concavity of glenoid fossa prevents its dislocation by translating forces.
Deltoid is the prime mover of shoulder abduction. All heads of the deltoid work together to produce abduction of the Shoulder Joint. It helps lift the arm front, side, and backward.

This is a stabilizing mechanism in which compression of the humerus into the concavity of glenoid fossa prevents its dislocation by translating forces.
In this paper, we summarize the structural and biomechanical information neces- sary for analysis of movement of the shoulder complex. We then review the literature describing shoulder complex movement and analyzing spe- cific muscle functions.
