Strengthen your shoulders and do not try to play or work through the pain.īone Spurs = small deposits of calcium, which build up along the edges of the bones.

The operation performed is Arthroscopic Subacromial Decompression (ASD) Prevention Surgery - Rarely Surgery is required - the goal of any surgery to reduce the effects of impingement, by increasing the amount of space between the acromion and the rotator cuff tendons, which will then allow for easier movement and less pain and inflammation. Injections - reduces inflammation and control the pain, allows the rotator cuff muscles a chance to recover and improve with the exercisesĤ. Physiotherapy - the key part of management to work on good posture, shoulder blade positioning and strengthening of the weakened rotator cuff musclesģ. Painkillers and anti-inflammatory medicationsĢ. Treatment of impingement syndrome involves:ġ. Subacromial bursa under the acromion Subacromial bursa removed to show rotator cuffĪcromial bone spur developed off acromion Bone spur removed by surgery with cut ligament Impingement may become a serious problem for some people and disturb their normal activities.

Each time the arm is raised there is a bit of rubbing on the tendons and the bursa between the tendons and the acromion, which may cause pain and inflammation. The rotator cuff and acromion will then rub against one another, causing a painful condition known as impingement. Therefore somebody with a rotator cuff injury who has a type III acromion and is their 50’s has a very high risk of developing significant impingement compared to a patient in their 20’s sustaining a supraspinatus strain who may have a type I acromion and no spurs. This further reduces the subacromial space increasing the risk of impingement. In addition to the above, with advancing age people tend to develop a bone spur on the front and side of the acromion. A person with a type II or type III acromion would be at a higher risk of impingement due to the narrowing of the acromiohumeral gap and bursal space. Type I is flat, type II is curved and type III hooked. These were described by Bigliani as type I, type II or type III. The acromion differs in individuals normally (morphological variants). Abnormal muscle patterning problems of the shoulder.Pathologies that could do this are those directly affecting the rotator cuff such as: Therefore as the arm is elevated, the depressing and centralising effect would be lost and the humeral head would ride upwards closer to the acromion at risk of causing impingement. Should any abnormality occur affecting the rotator cuff this would lead to dysfunction of the rotator cuff. As the arm is elevated the rotator cuff depresses the humeral head allowing it to glide easily underneath the acromion. The rotator cuff works a depressor and centraliser of the humeral head in the glenohumeral joint. This bursa is a fluid filled sac that allows for smooth gliding of the rotator cuff under the acromion with overhead movements of the shoulder. The space between the acromion and the rotator cuff tendons is filled by the subacromial bursa.

The rotator cuff lies under the roof of the shoulder (an extension of the shoulder blade known as the acromion ). The four muscles that raise and lower the arm (and their respective tendons) are collectively known as the rotator cuff. Also Known as: Trapped Tendons, Tendinitis, Bursitis What is it?
