Shouder & Elbow
The shoulder is the most flexible joint in the body enabling a wide range of movements including forward flexion, abduction, adduction, external rotation, internal rotation, and 360-degree circumduction.
As a result, the shoulder joint is considered the most insecure joint of the body but the support of ligaments, muscles and tendons function to provide the required stability.
The elbow is a complex joint formed by the articulation of three bones –the humerus, radius and ulna. The elbow joint helps in bending or straightening of the arm to 180 degrees and assists in lifting or moving objects.
The bones of the elbow are supported by
- Ligaments and tendons
- Blood vessels
