The rotator cuff is made up of four muscles and the tendons are attached to them under the roof of the shoulder that lowers and raises the arm. The acromion is an extension of the scapula. The subacromial pocket is in the space between the acromion and the rotator cuff. The subacromial bag is a sac filled with fluid that allows the rotator cuff below the acromion to slide smoothly when the shoulder is moved.
If all four tendons in the rotator cuff are injured, tense or Bone spore It develops in the acromion, it can result in the swelling of the tendons and also in the rubbing or pinching against the acromion as the space between the tendons and the acromion narrows. The tendons become irritated when they pass through this acromial space. This is called subacromial shock.
The subacromial shock is also known as shoulder impingement syndrome, supraspinatus syndrome, painful arch syndrome, shoulder of the thrower and shoulder of the swimmer.
Repeated activity where the shoulders move over, such as in tennis, painting, swimming, lifting heavy objects and abnormalities in bones and the joints are the risk factors of the subacromial shock.
The exact cause of the impact is not explicitly known.
The tendon can be divided if there is continuous wear. It can be caused by minor injuries. However, this injury can also be caused by repeated overload activities. Age is another cause. As one ages, bone spurs may develop in the acromion. In addition, tendons are prone to break after age 40. Sometimes, the shape of the acromion can make people prone to suffer a subacromial impact.
Subacromial impingement presents with the following symptoms:
Reaching over your back and reaching over your arms becomes difficult. The shoulder muscles weaken. The tendons can be broken in two if the lesions persist for a considerable time. This can result in a rotating break sleeve. Raising your arms becomes very difficult. Bicep tears are common if the shock persists.
