Because the shoulder is complex and intricate in design, it can also be prone to several types of injuries.
What is a Rotator Cuff?
The rotator cuff is the stabilizer of the shoulder. It is a group of four muscles and their tendons that wrap around the front, back, and top of the shoulder joint. These four muscles are also called the SITS Muscles: supraspinatus, infraspinatus, teres minor and subscapularis.
Most Common Types of Rotator Cuff Injuries:
Rotator Cuff Tear – an injury tears the rotator cuff tendon that has been weakened by age or wear-and-tear. Symptoms are pain and weakness in the arm. Therapy is needed and possible surgery depending on the severity of the tear.
Rotator Cuff Tendonitis – repetitive overhead use of the arms (as in painting or throwing), which causes a painful strain injury. Rest and ice. Possible therapy may be needed if pain does not lessen.
Impingement – tendons of the rotator cuff are squeezed between the humerus and acromion bones, causing pain, weakness and limited range of motion. Repetitive, overhead activities can cause this. The pain can be persistent and affect everyday activities. Treatment is needed to avoid thinning and tearing of the tendons.
Frozen Shoulder – also called adhesive capsulitis. This occurs when the humerus adheres to the shoulder blade, causing shoulder pain and stiffness. This needs time and exercises to heal. Steroid injections may help.
Sub-acromial Bursitis – inflammation of the small fluid-filled sac, or bursa, which cushions the rotator cuff tendons from the acromion bone. This can cause pain along the front and side of the shoulder, along with weakness and stiffness. Rest, ice, anti-inflammatory drugs, and therapy are needed.
