Understanding Rotator Cuff Tear Injuries
Shoulder injuries involving a rotator cuff tear are common in my San Diego chiropractic office, this is because these muscles are small and easily strained (strain means that some fibers have torn). Sports injuries work injuries and auto accidents commonly cause strains in the rotator cuff muscles.
The muscles of the rotator cuff coordinate rotational movements of the shoulder. There are four rotator cuff muscles as follows: supraspinatus, infraspinatus, teres minor and the subscapularis. The supraspinatus works to lift your arm off the site of your body and it is the most frequently injured of the rotator cuff muscles. The infraspinatus and teres minor both externally rotate your shoulder. Finally, the subscapularis works to internally rotate your shoulder.
