Causes of frozen shoulder. Frozen shoulder occurs when the sleeve that surrounds the shoulder joint, known as the capsule, becomes swollen and thickened. It's unclear why this happens. The shoulder is a ball and socket joint. The end of your upper arm bone (humerus) sits in contact with the socket of your shoulder blade (scapula).
A frozen shoulder is a shoulder joint with significant loss of its range of motion in all directions. The range of motion is limited not only when the patient attempts motion but also when the doctor attempts to move the joint fully while the patient relaxes.
