While this sport uses different muscles, they all involve repetitive use of the shoulder that can lead to potential shoulder instability (when the shoulder joint is loose and slides around too much in the socket). This repetitive motion can cause the shoulder ligaments to loosen and in some cases, slip out and dislocate or lead to arthritis. Frequent use of the shoulder can also cause severe problems with the rotator cuff.
The rotator cuff is the name for four distinct muscles and their tendons that surround the shoulder, that provide strength and stability during motion. Some of the most common shoulder conditions to the rotator cuff that can occur in the warmer months include impingement syndrome, bursitis, tendinitis and tendon ruptures or tears. All of these can vary in severity and if ignored, can aggravate the shoulder even further. One of the top injuries that we see at DIS is rotator cuff tears. So how do you know if you have a rotator cuff tear and if you need an MRI?
Any concerns, sharp pains or prolonged discomfort is a reason to visit your doctor; and a doctor that specializes in orthopedics is one that can help address concerns with your shoulder and rotator cuff. Rotator cuff tears do not heal; they can retract, leading to muscle atrophy and eventually cause arthritis in the shoulder. For these reasons, many orthopedic surgeons tend to order MRIs to evaluate the rotator cuff when someone presents with ongoing shoulder pain and weakness.
MRI is particularly beneficial for internal organs, muscles, connective tissue and the central nervous system and uses cross-sectional imaging to create extremely clear and detailed picture, allowing your physician to make an earlier and accurate diagnosis. In the instance of a rotator cuff injury, your doctor may recommend an MRI not only to diagnosis a tear, but rather, to exclude the possibility of one.
If your doctor does recommend an MRI for your shoulder, there are two potential types of MRI procedures that can be used to diagnose a rotator cuff tear: A routine shoulder MRI, which takes about 25 minutes of actual scan time, and shoulder MR arthrogram, which involves an X-ray procedure during which contrast is injected directly into the shoulder joint space followed by an MRI. An MR arthrogram is more specific for shoulder joint injuries, but is also more involved and requires the patient to be at the facility for about two hours. Your doctor can help determine which scan is the right one for your injury.
Arthrograms are performed at our Metairie – Veterans Memorial Boulevard, Marrero – Avenue C and Slidell locations.
