The supraspinatus is one of the four muscles that make up the rotator cuff, which helps to lift and rotate the arm. A tear in the supraspinatus tendon can be caused by trauma or repeated micro-trauma and can present as a partial or full-thickness tear. The pain from a supraspinatus tear can lead to sleep interruptions and make daily tasks such as putting on a jacket difficult. While a torn supraspinatus can cause pain in the shoulder and arm, it is not clear if it can cause pain in the pectoral muscle. The pectoralis minor, a small muscle that arises from the front of the upper ribs and attaches to the scapula, can exert a powerful influence on the shoulder and has been described as a hidden culprit in rotator cuff injuries.

Supraspinatus tears can be partial or full-thickness tears
A torn supraspinatus can cause pain in the pectoral muscle. The supraspinatus is part of the rotator cuff of the shoulder. It is one of the most frequently damaged tendons and is often accompanied by another rotator cuff muscle tear. A supraspinatus tear can occur due to trauma or repeated micro-trauma and can present as a partial or full-thickness tear.
Partial tears cause incomplete disruption to the muscle fibres. They can progress to complete tears, with increasing pain being the first sign of progression. Partial tears can be treated with medication, physical therapy, steroid injections, or surgery. Medication may include pain relief and anti-inflammatory drugs to reduce swelling in the shoulder. Physical therapy involves advice on exercises to restore flexibility and strength to the shoulder. Steroid injections can provide short-term pain relief if medication does not work.
Full-thickness tears cause a complete disruption of muscle fibres. They are larger tears (1-1.5cm) with a high rate of progression. They should be considered for earlier surgical repair in younger patients if the tear is repairable and muscle degeneration is limited. Surgical repair of full-thickness tears involves suturing the two parts of the tendon back together or attaching the tendon back to its original place by an anchor.
The treatment approach for supraspinatus tears depends on the severity of the tear, whether it is partial or full-thickness. It is important to regularly monitor both types of tears to detect any further progression or damage.

Tears can be caused by trauma or repeated micro-trauma
The supraspinatus muscle is one of the four muscles that make up the rotator cuff, which is essential for shoulder joint stability and movement. A torn supraspinatus muscle can indeed cause referred pain in the pectoral region, although it typically presents with pain over the front and side of the shoulder joint. The pain may radiate down the arm, but it is less common for it to localize to the pectoral muscle.

Rotator cuff tears are associated with older patients
A torn supraspinatus can cause pain in the pectoral muscle. It is one of the most frequently damaged tendons, usually developing alongside other rotator cuff tears. The rotator cuff is a group of four muscles that come together as tendons to form a covering around the head of the humerus. The supraspinatus tear can occur due to trauma or repeated micro-trauma and present as a partial or full-thickness tear. Most of the time, the tear occurs in the tendon or as an avulsion from the greater tuberosity. The tear can result in pain, loss of range of motion and weakness.
In addition to decreased blood flow, bone spurs can form on the top of the shoulder bone, creating friction between the bone and tendon. This shoulder impingement can eventually lead to a partial or complete tear. Rotator cuff tears can also be caused by overuse or another injury. Repetitive shoulder movements during sports or on the job can stress the muscles and tendons, causing a tear. Athletes are especially vulnerable to overuse tears, particularly tennis players and baseball pitchers.
The risk of a rotator cuff tear increases with age, and by the time someone is 60 years old, they are likely to have some partial or complete tears. However, people younger than 35 can also experience these tears, especially if they are athletes who engage in overhead sports. While rotator cuff tears are more common in older adults, they can affect people of all ages. Treatment options include nonsurgical methods such as rest, pain relievers, and physical therapy, as well as surgical repair in more severe cases.

Pain, loss of range of motion, and weakness are common symptoms
A tear in the supraspinatus tendon can result in pain, loss of range of motion, and weakness. This tendon is located at the back of the shoulder and is one of the most frequently damaged tendons. It is part of the rotator cuff, a group of four muscles that form a covering around the head of the humerus (upper arm bone). The rotator cuff tendons cover the head of the humerus and help to lift and rotate the arm.
When the supraspinatus tendon is torn, it can be either a partial or full-thickness tear. Partial tears cause incomplete disruption to the muscle fibres, while full-thickness tears result in a complete disruption. Traumatic tears can cause sudden, intense pain accompanied by immediate weakness in the upper arm. On the other hand, repetitive strain tears start with mild pain when lifting the arm, and the pain can become more noticeable over time, even at rest.
The pain and weakness caused by a supraspinatus tear can make daily tasks such as putting on a jacket difficult. It can also lead to sleep interruptions. The loss of range of motion associated with this type of tear can make it challenging to raise the arm above the shoulder. This difficulty in raising the arm is a common symptom of rotator cuff tears and can be evaluated through orthopaedic movement tests.
The pectoralis minor muscle, a small but powerful muscle in the chest, plays a crucial role in shoulder function and can be implicated in rotator cuff injuries. When this muscle is held in a shortened position or overused, it can pull the scapula forward, causing the upper arm to be held in an abnormally internally rotated position. This places tension on the supraspinatus tendon, making it susceptible to injury and potentially leading to tendonitis and impingement syndrome.
To summarise, pain, loss of range of motion, and weakness are indeed common symptoms associated with a torn supraspinatus tendon. These symptoms can significantly impact daily activities and sleep quality. The pectoralis minor muscle's influence on the shoulder complex can also contribute to rotator cuff injuries, including those involving the supraspinatus tendon.

Treatment options include medication, physical therapy, steroid injections, or surgery
A torn supraspinatus can cause pain in the pectoral muscle. It is a tear or rupture of the tendon of the supraspinatus muscle, which is part of the rotator cuff of the shoulder. The tear can be partial or full-thickness, with pain being one of the most common symptoms. Treatment options include medication, physical therapy, steroid injections, or surgery.
Medication may include pain relief and anti-inflammatory drugs to reduce swelling in the shoulder. Non-steroidal anti-inflammatory drugs (NSAIDs) are often recommended as they can help reduce pain and inflammation.
Physical therapy involves performing specific exercises to restore flexibility and strength to the shoulder. This is a common treatment approach for minor shoulder injuries and for patients recovering from shoulder surgery. It is important to note that the extent of the tear will determine the physical therapy management approach.
Steroid injections are sometimes used to provide short-term pain relief if medication has not been effective. However, the use of steroid injections for treating full-thickness rotator cuff tears is still controversial. While some studies support their use, others do not.
Surgery may be considered if the tendon has been severely torn and is unlikely to heal on its own. The approach to surgery depends on the severity of the tear. For partial tears, the tendon and surrounding bone may be smoothed to allow the tendon to heal. For complete tears, the two parts of the tendon may be sutured back together or reattached to the bone using anchors or screws. In extreme cases, surgery might involve replacing the shoulder joint.

Frequently asked questions
A supraspinatus tear is a tear or rupture of the supraspinatus tendon, which is located at the back of the shoulder. It is one of the most frequently damaged tendons and can occur due to trauma or repeated micro-trauma.
The three most common symptoms of a torn supraspinatus are pain, loss of range of motion, and weakness. Pain can be sudden and intense, or it can start off mild and become more noticeable over time.
Yes, a torn supraspinatus can cause pain in the pectoral muscle, specifically the pectoralis minor. This is because the pectoralis minor, when held in a shortened position or overused, can pull the scapula forward, causing the upper arm to be held in an abnormally internally rotated position. This places tension on the supraspinatus tendon, which can lead to tendonitis and pain.
