During the physical exam, your doctor will press on different parts of your shoulder and move your arm into different positions. He or she will also test the strength of the muscles around your shoulder and in your arms.
In some cases, he or she may recommend imaging tests, such as:
X-rays. Although a rotator cuff tear won't show up on an X-ray, this test can visualize bone spurs or other potential causes for your pain — such as arthritis.
Ultrasound. This type of test uses sound waves to produce images of structures within your body, particularly soft tissues such as muscles and tendons. It allows dynamic testing, assessing the structures of your shoulder as they move. It also allows a quick comparison between the affected shoulder and the healthy shoulder.
Magnetic resonance imaging (MRI). This technology uses radio waves and a strong magnet. The images obtained display all structures of the shoulder in great detail. The quality of the images depends greatly on the quality of the equipment used.
Conservative treatments — such as rest, ice and physical therapy — sometimes are all that's needed to recover from a rotator cuff injury. If your injury is severe and involves a complete tear of the muscle or tendon, you might need surgery.
If conservative treatments haven't reduced your pain, your doctor might recommend a steroid injection into your shoulder joint, especially if the pain is interfering with your sleep, daily activities or exercise. While such shots are often helpful, they should be used judiciously, as they can contribute to weakening of the tendon.
Physical therapy exercises can help restore flexibility and strength to your shoulder after a rotator cuff injury. Sometimes it is possible to eliminate pain and restore function without surgery.
Many different types of surgeries are available for rotator cuff injuries, including arthroscopic tendon repair, open tendon repair, bone spur removal, tendon transfer and shoulder replacement.
