What is Rotator Cuff?
Four muscles make the rotator cuff to help move and stabilize the shoulder joint. If any one of the four muscles or their ligaments are damaged, it can occur because of acute injury, chronic overuse or gradual aging which can cause significant pain and disability with range of motion or use of the shoulder joint.
Shoulder is a ball socket joint that allows arm to move in different directions. It is made up of humeral head fitting into the glenoid Fossa of the scapula or shoulder blade. Rotator cuff muscles are dynamic stabilizers and movers of the shoulder joint that can adjust the position of the humeral head and scapula. In the case of rotator cuff injury, different problems that can take place include:
Shoulder pain and spasm limit the range of motion of the shoulder, disallowing muscles to make small adjustments within the joint to allow humeral head to move smoothly. Fluid accumulation within the joint for the reason of inflammation limits movements and arthritis and calcium deposits that for over time limit range of motion are other issues that may arise.
Causes of Rotator Cuff Injury
Rotator cuff injury can occur from an acute injury, from chronic overuse or from gradual degeneration of the muscle and tendon due to aging. Acute rotator cuff tear and chronic tear are common causes. Acute rotator cuff tear can develop from sudden powerful rising of the arm against resistance or due to heavy lifting or fall on the shoulder.
Symptoms of Rotator Cuff Injury
Inflammation that accompanies strain is a common symptom that can cause swelling and decreased range of motion. Some other symptoms include acute rotator cuff tear, sudden tearing sensation followed by severe sharp shooting pain from the upper shoulder area and down the arm toward the elbow.
Acute pain from bleeding and muscle spasm, large tears may cause the inability to abduct the shoulder. Pain is usually worse at night; gradual weakness and decreased shoulder motion, etc, are other symptoms of rotator cuff injury.
The doctors and orthopaedic surgeons at Singapore Sports and Orthopaedic Clinic are able to provide you treatments for normal rotator cuff and torn rotator cuff injuries.
