The anatomy of the rotator The Back Pain Breakthrough Review cuff consists of 4 muscles - the supraspinatus, the infraspinatus, teres minor and subscapularis. There main function is to help move the arm in various directions as well as maintain normal mechanics when moving the shoulder. Rotator cuff pain can occur when theses muscles are injured or they cannot work together like they should.Injury to the shoulder muscles can cause inflammation to occur. This injury can be traumatic (like falling or lifting too heavy a weight) or it can be repetitive (like pounding a hammer overhead for a prolonged time). Either way both can cause pain and swelling in the muscles. The cuff muscles are surrounding by bone and when they swell they can easily get pinched under this bone, especially when trying to raise your arm overhead. This pinching is called an impingement can can be very painful. You can also get an impingement even if your muscles are not swollen. If the cuff muscles are weak then your shoulder won't move correctly and this will cause the muscles to get pinched under the bone, again causing pain.
Other common causes of rotator cuff pain are from tendonitis and bursitis. Tendonitis means that a muscle tendon is inflamed. Bursitis means that the bursal sac is inflamed. The bursal sac is a fluid filled sac that sits between muscle and bone to protect the muscle from scraping on the bone. It has a lot of nerve endings so when it is inflamed it becomes very painful. Both of these structures can cause significant pain at the shoulder region and both can be effectively treated with conservative measures.
Laxity at the shoulder can be due to your normal genetics. Some people are just born that way. This type of "looseness" at the shoulder will cause your joint mechanics to be abnormal which can result in overuse type injuries affecting the tendons and bursa. Laxity can also be caused by trauma - car accident, falling on an outstretched arm, injuries that force your shoulder to its end range of motion unexpectedly. These types of situations can cause the shoulder to pop out of joint (a dislocation). This causes the shoulder capsule to stretch and become loose. Once the capsule is loose the shoulder joint can pop out of its socket more easily and frequently. This can be helped with the right exercises to strengthen the surrounding muscles. The stronger the muscles are the better they can stabilize and stiffen the joint. If the capsule is stretched out too far then surgery is likely needed to correct this problem
Rotator cuff pain can also be caused by a condition known as frozen shoulder. This means that the capsule that surrounds the shoulder has become very stiff and it won't move well. This immobility causes your shoulder motion to become very limited and painful. In many cases the correct performance of exercises can improve the immobility and relieve the pain.Have you been dealing with rotator cuff pain (pain in or near your shoulder) in hopes that it will just go away? This type of pain can be debilitating and force you to stop your normal level of activity. It can prevent you from doing basic things like getting dressed, washing your hair, playing with your kids and recreational activities. Rotator cuff pain can also force you to lose time from work as it affects your ability to do your job. This article will highlight some of the more important aspects of this painful condition.
