Subacromial Impingement

Subacromial Impingement_Banner

Shoulder pain is one of the most common musculoskeletal complaints and can affect people of all ages. A frequent cause of this pain is rotator cuff tendinitis and shoulder impingement, conditions involving irritation of the tendons and soft tissues around the shoulder joint.

The rotator cuff muscles and tendons play a key role in lifting and rotating the arm. When these structures become inflamed or compressed, shoulder movements can become painful and restricted.

Shoulder Anatomy – Understanding the Problem

The shoulder is a highly mobile joint made up of:

  • Humerus (upper arm bone)
  • Scapula (shoulder blade)
  • Clavicle (collarbone)

The rotator cuff tendons attach to the top of the humerus and help stabilize and move the shoulder.

Between the rotator cuff and the bony roof of the shoulder (the acromion) lies a fluid-filled sac called the bursa, which allows smooth movement during arm elevation.

What Is Shoulder Impingement?

Rotator cuff–related shoulder pain can occur due to:

  • Tendinitis – inflammation of the rotator cuff tendons
  • Bursitis – inflammation of the bursa
  • Impingement syndrome – narrowing of the space between the acromion and rotator cuff tendons

When you raise your arm, the acromion may rub against the rotator cuff and bursa, causing pain, irritation, and inflammation.

Causes & Risk Factors

Shoulder impingement and rotator cuff tendinitis are common in:

  • Young athletes involved in overhead sports such as cricket, tennis, swimming, volleyball, and baseball
  • People doing repetitive overhead or lifting activities, such as painters, construction workers, and electricians
  • Older individuals due to age-related tendon wear
  • Minor injuries or repetitive strain, sometimes without a clear injury

Symptoms of Subacromial Impingement

Early Symptoms

  • Mild shoulder pain with activity or rest
  • Pain radiating from the front or side of the shoulder down the arm
  • Pain during lifting or reaching movements
  • Discomfort during throwing or overhead sports

Progressive Symptoms

  • Increasing pain and stiffness
  • Severe night pain, affecting sleep
  • Loss of strength and shoulder movement
  • Difficulty with daily activities such as dressing, wearing a seatbelt, or grooming

In some cases, pain may begin suddenly, and shoulder movement may become severely limited.

Doctor Evaluation & Diagnosis

(1) Physical Examination

Your doctor will:

  • Check for tenderness around the shoulder
  • Assess range of motion and strength
  • Gently move the shoulder if pain limits active movement
  • Examine the neck to rule out nerve-related pain
  • Look for other shoulder conditions such as arthritis or instability

(2) Imaging Tests

  • X-rays: Usually normal but may show bone spurs on the acromion
  • Special outlet view X-ray: Can reveal acromial spurs causing impingement
  • MRI or Ultrasound:
    • Shows inflammation of the rotator cuff or bursa
    • Detects partial or full-thickness rotator cuff tears

Treatment Options for Subacromial Impingement

The aim of treatment is to reduce pain, restore movement, and improve shoulder function. Treatment is tailored based on age, activity level, and severity of symptoms.

(1) Non-Surgical Treatment

Most patients improve with conservative (non-surgical) care:

  • Rest and activity modification, especially avoiding painful overhead movements
  • Pain medications (NSAIDs) to reduce pain and inflammation
  • Physical therapy
    • Stretching exercises to restore motion
    • Strengthening of rotator cuff and shoulder blade muscles
    • Posture correction to prevent recurrence
  • Steroid injections
    • Reduce inflammation and pain
    • Usually injected into the subacromial bursa
    • May be done with ultrasound guidance for accuracy

Recovery may take several weeks to months, but most patients return to normal activities without surgery.

(2) Surgical Treatment

Surgery is considered when:

  • Pain persists despite adequate non-surgical treatment
  • Shoulder function remains significantly limited

(3) Arthroscopic Surgery (Keyhole Surgery)

The goal is to create more space for the rotator cuff tendons by:

  • Removing inflamed bursal tissue (bursectomy)
  • Removing bone spurs and reshaping the acromion (acromioplasty / subacromial decompression)

During surgery, other associated problems may also be treated, such as:

  • Acromioclavicular (AC) joint arthritis
  • Biceps tendinitis
  • Partial or full-thickness rotator cuff tears

Recovery & Rehabilitation

  • Short period of sling support if required
  • Early shoulder exercises as comfort allows
  • Structured physiotherapy to restore motion and strength
  • Most patients experience significant improvement within 2-4 months
  • Full recovery may take up to 1 year, depending on associated procedures
