  An injured rotator cuff is diagnosed when muscles and tendons that support and surround the shoulder joint are torn. […] Rotator cuff injury is the most common shoulder disorder and affects 20% to 40% of the general population. […] A rotator cuff injury happens when one or more of the four muscles or tendons that form the cuff are damaged. […] Tendons are injured more commonly than muscles. […] Shoulder problems such as shoulder impingement can lead to rotator cuff injuries over time. […] Both acute and chronic injuries can cause tearing of the rotator cuff muscles. […] Injury to the muscle or tendon occurs in one of 2 ways: Acute injuries: Overstretching or tearing of muscles or tendons that results from a one-time traumatic event, such as holding out the arm to break a fall or an acute sports injury (eg, horseback riding, hockey, and soccer)

• #37 Rotator Cuff Tear: Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/8291-rotator-cuff-tear

  A rotator cuff tear is an injury to your rotator cuff that can cause shoulder pain and the inability to use your arm. […] A tear may result from overuse or another injury. […] More commonly, rotator cuff tears occur over time as your tendon wears down with age and use (degenerative tear). People over age 40 are most at risk. […] Causes of degenerative tears include: […] Bone spurs: Bony growths can form on the top of your shoulder bone. These bone spurs rub against your tendon when you lift your arm. This shoulder impingement creates friction between your bone and tendon. Eventually, a partial or complete tear may occur. […] Decreased blood flow: Blood flow to your rotator cuff decreases as you get older. Your muscles and tendons need a healthy blood supply to repair themselves. If blood doesn’t nourish your tendons, they can tear.

  Its also common to form bone spurs on the underside of the acromion (a bony protrusion on top of your shoulder blade) as you age. These spurs rub on the tendons of the rotator cuff every time you lift your arms, resulting in a condition known as impingement that can weaken the tendon and cause a tear.

  Acute Tear An injury to your shoulder will often cause a rotator cuff tear. Common mechanisms of injury include falls onto your outstretched arm or lifting something too heavy with a jerking motion. It can also occur with other shoulder injuries, such as a dislocated shoulder. […] Degenerative Tear Many tears are the result of degenerative wearing down of the tendon that occurs slowly over time, as we age. If you have a degenerative tear in one shoulder, there is a high likelihood of developing a rotator cuff tear in the opposite shoulder. Several factors contribute to degenerative, or chronic, rotator cuff tears. Repetitive stress. Repeating the same shoulder movements again and again can damage your rotator cuff muscles and tendons over time. Many physical jobs and routine chores can cause overuse tears. They are also commonly seen in sportspeople. Bone spurs. As we age, bone spurs (bone overgrowth) often develop on the underside of the acromion bone. When we lift our arms, the spurs rub on the rotator cuff tendon. This condition is called shoulder impingement, and over time will weaken the tendon and make it more likely to tear. Poor blood supply. As we age, the blood supply in our rotator cuff tendons weakens impairing the body’s natural ability to repair tendon damage.

• #41 Shoulder Impingement (Rotator Cuff Tendinitis)

  https://my.clevelandclinic.org/health/diseases/shoulder-impingement-rotator-cuff-tendinitis

  Shoulder impingement happens when bones in your shoulder rub against or pinch your rotator cuff. […] Rotator cuff tendinitis is exactly what its name sounds like tendinitis that affects your rotator cuff. Tendinitis is swelling or irritation of a tendon. […] Shoulder impingement is almost always an overuse injury. This means it happens over time when an activity or motion repeatedly puts too much stress on your shoulder joint and rotator cuff. […] Healthcare providers call the kinds of movements that cause shoulder impingement overhead rotation motions any repetitive motion that requires you to twist and turn your shoulders with your arms raised. […] Some people develop shoulder impingement without an obvious cause (idiopathically). Its also possible for trauma (like a fall, car accident or sports injury) to cause impingement suddenly. […] Anything that irritates your rotator cuff and the tissue in your shoulder joint can cause shoulder impingement.

  Rotator cuff problems come in all shapes and sizes. Most of these issues can be divided into tendonitis, partial tears, or full tears of the rotator cuff. […] Up to 60% of patients who are over 60 years old have full thickness rotator cuff tears. […] The reason you can have both a partial and full thickness tear is because the rotator cuff is made up of multiple layers of tissue just like how toilet paper is made of two plies. The rotator cuff has its own layers of tissue. There are five layers in the rotator cuff, and you can have injuries or tears involving one or multiple tissue layers. […] The tear can grow with time, and the muscles can undergo fatty changes, which means the tendon has torn off the bone, and the muscle has nothing to pull against. Over time, the muscle wears out and turns into fat.

  As we get older, the blood supply in our rotator cuff tendons decreases. Without a good blood supply, the body’s natural ability to repair tendon damage is impaired. This can ultimately lead to a tendon tear. […] Because most rotator cuff tears are largely caused by the normal wear and tear that goes along with aging, people over 40 are at greater risk. […] People who do repetitive lifting or overhead activities are also at risk for rotator cuff tears. Athletes are especially vulnerable to overuse tears, particularly tennis players and baseball pitchers. […] Although overuse tears caused by sports activity or overhead work also occur in younger people, most tears in young adults are caused by a traumatic injury, like a fall.

  Rotator cuff strains or tears are generally caused by: […] Rotator cuff injuries can range from mild to severe. They tend to fall into one of two categories: acute or chronic. Tendinitis (acute) or tendinopathy (chronic) is typically caused by overuse of the rotator cuff muscle. This causes it to become irritated. The tendons that connect muscles to bones can overstretch (strain) or tear, partially or completely. […] Tennis players who use an overhead serve and painters who have to reach upward to do their jobs commonly experience this injury. The rotator cuff can also be strained or tear after a fall, a car accident, or another sudden injury. These injuries typically cause intense and immediate pain. […] Acute injuries usually occur from one particular incident. These can be caused by lifting objects that are too heavy, falling, or having the shoulder forced into an awkward position. Young people are more likely to experience this type of rotator cuff injury. […] Degenerative injuries are due to long-term overuse. People most at risk for these injuries include: athletes, particularly tennis players, baseball players, rowers, and wrestlers; people with jobs that require repetitive lifting, like painters and carpenters; people above 40 years of age.

  Rotator Cuff Injury: Causes, Symptoms, Treatment Wear and tear due to ageing is a common cause for rotator cuff problems. […] Normal wear and tear: As the tendon of the rotator cuff has poor blood supply, it tends to be prone to degeneration due to ageing. The degeneration can be aggravated by repetitive shoulder movements. Hence this condition typically occurs if you are above 40. […] Repetitive movements: Athletes who regularly use overhead repetitive movements such as swimmers, rowers or tennis players are at higher risk of rotator cuff injuries. However, the injury can also happen through seemingly trivial activities like carrying a heavy load overhead or hanging clothes outside. […] Trauma: The rotator cuff can also be damaged from a single traumatic injury such as a fall or a hard direct hit to the arm. […] Heavy lifting or pulling: Lifting or pulling an object that is too heavy or lifting in the wrong way can cause strain or a tear to the rotator cuff muscle or tendon.

  Acute Tear An injury to your shoulder will often cause a rotator cuff tear. Common mechanisms of injury include falls onto your outstretched arm or lifting something too heavy with a jerking motion. It can also occur with other shoulder injuries, such as a dislocated shoulder. […] Degenerative Tear Many tears are the result of degenerative wearing down of the tendon that occurs slowly over time, as we age. If you have a degenerative tear in one shoulder, there is a high likelihood of developing a rotator cuff tear in the opposite shoulder. Several factors contribute to degenerative, or chronic, rotator cuff tears. Repetitive stress. Repeating the same shoulder movements again and again can damage your rotator cuff muscles and tendons over time. Many physical jobs and routine chores can cause overuse tears. They are also commonly seen in sportspeople. Bone spurs. As we age, bone spurs (bone overgrowth) often develop on the underside of the acromion bone. When we lift our arms, the spurs rub on the rotator cuff tendon. This condition is called shoulder impingement, and over time will weaken the tendon and make it more likely to tear. Poor blood supply. As we age, the blood supply in our rotator cuff tendons weakens impairing the body’s natural ability to repair tendon damage.

[…] More commonly, rotator cuff tears occur over time as your tendon wears down with age and use (degenerative tear). People over age 40 are most at risk. […] Causes of degenerative tears include: […] Bone spurs: Bony growths can form on the top of your shoulder bone. These bone spurs rub against your tendon when you lift your arm. This shoulder impingement creates friction between your bone and tendon. Eventually, a partial or complete tear may occur. […] Decreased blood flow: Blood flow to your rotator cuff decreases as you get older. Your muscles and tendons need a healthy blood supply to repair themselves.

  A rotator cuff tear is a tear in any one of the tendons of the rotator cuff. […] A minor, partial tear can occur over time from overuse, or prolonged wear and tear (degeneration). Partial tears can progress to full-thickness rotator cuff tears over time. Complete ruptures can also be caused by a trauma such as dislocating your shoulder or by performing a sudden and heavy lift. […] When trauma is the immediate cause of a tear, it is often the case that existing tendon degeneration or a prior, less severe rotator cuff injury has played a contributing role.

  Rotator cuff problems come in all shapes and sizes. Most of these issues can be divided into tendonitis, partial tears, or full tears of the rotator cuff. […] Up to 60% of patients who are over 60 years old have full thickness rotator cuff tears. […] The reason you can have both a partial and full thickness tear is because the rotator cuff is made up of multiple layers of tissue just like how toilet paper is made of two plies. The rotator cuff has its own layers of tissue. There are five layers in the rotator cuff, and you can have injuries or tears involving one or multiple tissue layers. […] The tear can grow with time, and the muscles can undergo fatty changes, which means the tendon has torn off the bone, and the muscle has nothing to pull against. Over time, the muscle wears out and turns into fat.

  The rotator cuff is a group of muscles and tendons surrounding the shoulder joint that provide strength for shoulder motion. A rotator cuff tear occurs when one of these tendons detaches from the bone, usually from overuse or traumatic injury. […] Most rotator cuff injuries are wear-and-tear overuse conditions, caused by repeated arm movements over time. The tissues in the rotator cuff can break down, leading to conditions such as tendinitis and bursitis. Rotator cuff tears can occur gradually from repetitive motion or suddenly from overloading, such as from a bike fall or crash. […] Rotator cuff injuries may be the result of a substantial injury to the shoulder. For example, a fall or other accident that leads to a broken collarbone or dislocated shoulder can also cause a sudden tear in the rotator cuff.

  https://floridasurgeryconsultants.com/conditions/rotator-cuff-tear/

  The rotator cuff is a set of four muscles supraspinatus, infraspinatus, subscapularis, and teres minor that come from the scapula (shoulder blade) and their tendons that keep your humerus (upper arm bone) attached to the shoulder socket. It is responsible for keeping the entire arm stable and mobile. Rotator cuffs get a lot of everyday use. The likelihood of rotator cuff tears will depend on a combination of factors like your age, occupation, daily activities, sports activities, or a traumatic injury. […] A rotator cuff tear develops more over time than through a sudden injury. Usually, it occurs in people who perform constant overhead motions or activities in their jobs such as carpenters, painters, basketball players, etc. The normal wear and tear or repetitive arm motions develop. The risk of developing these diseases increases with age.

  The rotator cuff is a group of 4 muscles that surround the shoulder (glenohumeral joint). The most commonly injured muscle is the supraspinatus. The supraspinatus often gets impinged upon (pinched) due to biomechanical dysfunction in the shoulder. […] If the process continues to occur (months) the tendon will slowly begin to degenerate, which can cause pain/discomfort, weakness – particularly with shoulder abduction and reduced range of movement; we term this tendinosis. […] If you have chronic supraspinatus tendinosis for long enough (years) eventually the tendon will begin to fray (tear), if it tears enough you will experience significant pain and reduced range of motion. […] Other causes include work related or sleeping postures, as well as repetitive activities which may be overloading certain structures and causing problems.

  When a tear occurs in the cuff, it can involve one, or potentially all, of the rotator cuff tendons. […] What causes a rotator cuff tear? For some people, it’s very obvious that a single event caused them a big pain in the shoulder – for instance if they picked up a very heavy object, or a fall caused them to severely jar the shoulder. When the rotator cuff is injured in this manner, we call it a traumatic tear. […] It may be that your pain has gradually accrued over time after working in the garden or doing lots of sport. This slower brewing tear is known as a degenerative or chronic tear.

  A chronic tear of the rotator cuff tendon occurs slowly over time. It is more likely when you have chronic tendinitis or impingement syndrome. At some point, the tendon wears down and tears. […] Rotator cuff tears may occur in two ways: A partial tear occurs when a tear does not completely sever the attachments to the bone. A complete, full thickness tear means that the tear goes all the way through the tendon. It may be as small as a pinpoint, or the tear may involve the entire tendon. With complete tears, the tendon has come off (detached) from where it was attached to the bone. It can also be retracted and be pulled away from the bone. This kind of tear does not heal on its own.
