Shoulder Impingement

Shoulder impingement occurs when the rotator cuff tendons are compressed under the acromion bone, causing pain and limited overhead motion.

About Shoulder Impingement

Shoulder impingement, also known as subacromial impingement syndrome, occurs when the rotator cuff tendons become compressed or pinched between the humeral head (upper arm bone) and the acromion (bony prominence on the shoulder blade). This compression causes inflammation, pain, and progressive damage to the tendons. At Mountain Spine & Orthopedics, our shoulder specialists understand that impingement is often the first stage in a continuum that can progress to rotator cuff tears if left untreated.

Impingement typically develops from structural abnormalities like bone spurs on the acromion, poor posture, or muscle imbalances that cause the humeral head to ride up and compress the tendons. Repetitive overhead activities common in sports like swimming, tennis, or baseball, or occupations like painting or construction, are major risk factors. Early diagnosis and treatment are essential to prevent progression to more serious tendon damage.

What Are the Symptoms of Shoulder Impingement?

Patients with shoulder impingement typically experience pain when raising the arm overhead or reaching behind the back, pain at night especially when lying on the affected side, and weakness with overhead activities. The pain is often described as a sharp, catching sensation during specific movements. Many patients notice the pain is worse with repetitive overhead motions.

Are There Specific Risk Factors for Shoulder Impingement?

Risk factors include repetitive overhead activities (sports or occupations), poor posture with forward head position, bone spurs on the acromion, weak rotator cuff or scapular stabilizer muscles, advancing age, and previous shoulder injuries that altered joint mechanics.

Diagnosing Shoulder Impingement?

Diagnosis involves a comprehensive physical examination including specific impingement tests like the Neer test and Hawkins-Kennedy test. X-rays can reveal bone spurs or acromial shape abnormalities. MRI is often used to evaluate the rotator cuff tendons for inflammation or early tears. We offer complimentary MRI reviews to accurately assess your condition. Ultrasound can provide dynamic evaluation of the tendons during movement.

Treatment for Shoulder Impingement?

Non-Surgical Treatment Options

Initial treatment focuses on reducing inflammation and correcting muscle imbalances. This includes rest from aggravating activities, anti-inflammatory medications, and physical therapy to strengthen the rotator cuff and improve scapular stability. Corticosteroid injections into the subacromial space can provide significant pain relief.

Surgical Treatment

When conservative treatment fails, our surgeons perform arthroscopic subacromial decompression (acromioplasty) to remove bone spurs and create more space for the rotator cuff tendons. This minimally invasive procedure is highly effective for relieving impingement and preventing progression to rotator cuff tears.

Does Shoulder Impingement Cause Pain?

Impingement pain typically worsens with overhead activities and can become constant over time if left untreated. The pain often disrupts sleep, especially when lying on the affected shoulder. Early treatment can prevent the condition from progressing to more serious tendon damage.

What Can Patients Do to Prevent It?

Preventing shoulder impingement requires addressing the underlying causes:

  • Maintain proper posture to prevent forward head position
  • Strengthen rotator cuff and scapular stabilizer muscles
  • Avoid repetitive overhead activities without proper rest
  • Use proper lifting techniques and body mechanics
  • Address early symptoms promptly with rest and evaluation
  • Practice shoulder flexibility exercises regularly

Frequently Asked Questions

What is shoulder impingement syndrome?

Shoulder impingement occurs when the rotator cuff tendons are compressed between the humerus and acromion bone during arm elevation. Repetitive overhead activities, poor posture, and bone spurs narrow the subacromial space, causing inflammation and pain.

What are the symptoms of shoulder impingement?

Symptoms include pain when raising the arm overhead, especially between 60-120 degrees (painful arc), weakness, night pain, and difficulty reaching behind the back. Pain typically worsens with overhead activities and improves with rest.

Can shoulder impingement heal on its own?

Mild cases may improve with activity modification and rest, but most require targeted treatment. Physical therapy, NSAIDs, and corticosteroid injections address inflammation. Without treatment, chronic impingement can lead to progressive rotator cuff damage and tears.

How is shoulder impingement treated?

Treatment begins with physical therapy strengthening rotator cuff and scapular stabilizers, NSAIDs, activity modification, and subacromial injections. If conservative care fails after 3-6 months, arthroscopic acromioplasty removes the bone spur and creates more space.

How long does shoulder impingement take to heal?

Most cases improve within 6 to 12 weeks with proper therapy and avoiding aggravating activities. Severe or chronic impingement may require 3-6 months. Surgical decompression adds 3-4 months for full recovery including rehabilitation.
