MRI. This test uses a combination of large magnets, radiofrequencies, and a computer to make detailed images of organs and structures within the body. A rotator cuff may tear partly or fully. What causes a rotator cuff injury? Injury and degeneration are the two main causes of rotator cuff tears.
If it’s ignored, a torn rotator cuff can fray even further over time, causing the tear to deepen — and the ensuing shoulder pain, stiffness, weakness, and immobility to worsen. A short tutorial on frozen shoulder. Frozen shoulder occurs when the tough, flexible capsule that surrounds the shoulder joint becomes inflamed.
