Does Shoulder Injury Require X-ray or MRI?

I started a weight-lifting program at home two weeks ago. When I increased to 20 pounds for shoulder movements, I felt a pop in my left shoulder. There was a twinge of pain at the time, and the next day I had extreme shoulder pain. I went to see the doctor, and she said I tore the supraspinatus tendon. There were no X-rays or other tests done. Shouldn’t I have X-rays or MRI?

X-rays have limited value in a case like this. Your doctor might have ordered an X-ray if she thought you could have fractured a bone. MRI (magnetic resonance imaging) is a useful test to identify damaged shoulder tendons. However, it is not always necessary to perform these studies. MRIs are very expensive, and most tendon tears can be accurately identified with a careful physical examination and history. An MRI is probably not necessary unless the doctor is considering surgery. If you do not get better after a program of physical therapy, the doctor may reconsider ordering an MRI. Getting a second opinion from another doctor may confirm the diagnosis at a lesser cost.

What is a rotator cuff and how does it get torn?

I recently fell and hurt my shoulder. The doctor told me that I have a rotator cuff tear. What is the rotator cuff, and what part is usually torn?

 

There are four muscles that make up the rotator cuff. The tendons from each muscle encircle the top of the shoulder, much like the cuff of a sleeve goes around the entire wrist. The rotator cuff holds the humerus in the socket of the shoulder joint while still allowing it to turn, or rotate (hence the word “rotator”).

Usually only one or two tendons of the rotator cuff are torn. The tear commonly occurs close to where the tendon attaches to the bone. It is rare for all four tendons to be injured at the same time.
