Subcoracoid Impingement: Signs, Causes, And How To Treat
Subcoracoid impingement happens when the tissues in the shoulder get pinched under the coracoid process, a bony projection in the shoulder joint. This can lead to discomfort and limited movement in the shoulder area. The condition can develop due to repetitive overhead activities or poor shoulder mechanics.
It's important to address the underlying causes and seek proper guidance from a healthcare provider to manage this issue effectively. By understanding how subcoracoid impingement occurs, you can take steps to prevent further strain on your shoulder and improve your overall shoulder health.
What Are the Symptoms of Subcoracoid Impingement
Patients may experience weakness and limited range of motion. Activities like lifting, reaching, or throwing may worsen the symptoms. Seeking early medical evaluation is essential for proper diagnosis and treatment to alleviate discomfort and prevent further complications.
- Pain in the front of the shoulder that worsens when lifting the arm overhead is a common symptom of subcoracoid impingement.
- Difficulty reaching behind the back or across the body due to shoulder pain can be a sign of subcoracoid impingement.
- Weakness or a feeling of instability in the shoulder may indicate subcoracoid impingement.
- Clicking or popping sensations in the shoulder joint when moving the arm could be a symptom of subcoracoid impingement.
- Limited range of motion in the shoulder, especially when trying to rotate the arm, is often experienced by individuals with subcoracoid impingement.

Other contributing factors include repetitive overhead activities, muscle imbalances, and poor shoulder mechanics. These issues can lead to compression of the subscapularis tendon and biceps tendon in the subcoracoid space, resulting in pain and limited shoulder movement.
- Subcoracoid impingement can be caused by repetitive overhead activities such as throwing or swimming, leading to compression of the structures beneath the coracoid process in the shoulder joint.
- Anatomical variations, such as a downwardly sloping acromion or a prominent coracoid process, can contribute to subcoracoid impingement by narrowing the subcoracoid space and increasing the risk of soft tissue compression.
- Traumatic injuries to the shoulder, such as dislocations or fractures, can result in subcoracoid impingement due to the disruption of normal shoulder biomechanics and the potential for structural damage within the joint.
Types of Subcoracoid Impingement
Subcoracoid impingement can be classified into two types: internal impingement and anterior subcoracoid impingement. Internal impingement occurs when the rotator cuff tendons and the labrum get pinched between the humeral head and the glenoid. Anterior subcoracoid impingement happens when the subscapularis tendon rubs against the coracoid process, leading to pain and limited range of motion in the shoulder.
- Anterior subcoracoid impingement occurs when the subscapularis tendon and adjacent structures become compressed beneath the coracoid process, leading to pain and limited range of motion in the shoulder joint.
- Subcoracoid bursitis is a type of impingement where inflammation and swelling of the bursa located beneath the coracoid process cause pain and discomfort in the front of the shoulder.
- Subcoracoid stenosis involves narrowing of the subcoracoid space, often due to repetitive overhead activities, resulting in compression of the soft tissues and nerves in the area.
Risk Factors
Risk factors for subcoracoid impingement include shoulder trauma, repetitive overhead activities, poor posture, muscle imbalances, and anatomical variations in the coracohumeral ligament. These factors can lead to compression of structures beneath the coracoid process, causing pain and restricted shoulder movement. Proper diagnosis and management are essential for addressing this condition effectively.
- Participating in overhead activities such as swimming, tennis, or weightlifting can increase the risk of developing subcoracoid impingement due to repetitive strain on the shoulder joint.
- Having poor posture, especially rounded shoulders, can lead to abnormal biomechanics in the shoulder complex and predispose individuals to subcoracoid impingement.
- Individuals with shoulder instability or previous shoulder injuries are more vulnerable to developing subcoracoid impingement as these conditions can alter the normal mechanics of the shoulder joint.
- Poor scapular control and muscle imbalances, particularly weakness in the rotator cuff muscles or scapular stabilizers, can contribute to the development of subcoracoid impingement.

Diagnosis of Subcoracoid Impingement
Subcoracoid impingement is diagnosed through a physical exam, where your doctor will assess your range of motion and pain in your shoulder. X-rays or MRI scans may also be ordered to visualize any bone spurs or soft tissue damage. By evaluating these findings, your healthcare provider can determine if subcoracoid impingement is the cause of your shoulder pain and recommend appropriate treatment.
- Physical examination by a healthcare provider to assess range of motion and strength in the affected shoulder, as well as identify any specific areas of tenderness.
- Imaging tests such as X-rays to rule out other shoulder conditions and evaluate bone structures for any abnormalities that may be causing impingement.
- MRI (magnetic resonance imaging) to provide detailed images of soft tissues, including muscles, tendons, and ligaments, to identify any tears or inflammation contributing to subcoracoid impingement.
- Ultrasound examination to assess the integrity of the rotator cuff tendons and identify any signs of impingement or inflammation in the subcoracoid space.
Treatment for Subcoracoid Impingement
Treatment options for subcoracoid impingement typically include rest, physical therapy to strengthen and stretch the shoulder muscles, anti-inflammatory medications, and corticosteroid injections to reduce pain and inflammation. In severe cases, surgery may be recommended to create more space in the shoulder joint. It is essential to follow your healthcare provider's recommendations and participate in rehabilitation to achieve the best outcomes.
- Physical therapy is often recommended for subcoracoid impingement to strengthen the muscles surrounding the shoulder joint and improve range of motion, helping to alleviate pain and prevent further impingement.
- Corticosteroid injections may be used to reduce inflammation and provide short-term pain relief in cases where conservative treatments have not been effective in managing symptoms of subcoracoid impingement.
- In some cases, arthroscopic surgery may be necessary to address structural issues causing subcoracoid impingement, such as removing bone spurs or repairing damaged tendons in the shoulder joint.
- Activity modification and ergonomic adjustments can help reduce strain on the shoulder joint, minimizing the risk of impingement.
