Shoulder Impingement Syndrome

Symptoms, Diagnosis & Treatment Options

Impingement is one of the most common causes of shoulder pain — a pinching of the rotator cuff tendons in the narrow space beneath the shoulder blade. Most cases settle without surgery.

Impingement happens when the rotator cuff tendons are compressed in the narrow space between the top of the arm bone and the bony arch of the shoulder blade (the acromion). Every time you lift the arm, that space narrows — and if it is too tight, the tendons are pinched and become inflamed.

1. Anatomy & Overview

Impingement happens when the rotator cuff tendons are compressed in the narrow space between the top of the arm bone and the bony arch of the shoulder blade (the acromion).

Clinical examination

2. Signs & Symptoms

Pain when lifting the arm — especially in the mid-range and overhead.

Diagnostic imaging

3. Diagnosis & Imaging

Specific tests load the shoulder in positions that reproduce the pinch, helping to confirm impingement and distinguish it from a cuff tear.

Treatment

4. Treatment Options

The great majority of cases improve with non-surgical care aimed at restoring movement and creating space for the tendons.

Rehabilitation

5. Recovery & Rehabilitation

With consistent rehabilitation, most patients improve over several weeks to a few months and return to overhead activity.

Frequently Asked Questions

What are the symptoms of Shoulder Impingement Syndrome?

Pain when lifting the arm — especially in the mid-range and overhead. A painful arc — with discomfort easing once the arm is fully raised. Night pain — particularly when lying on the affected side. Weakness or reluctance — to reach overhead or behind the back.

What causes Shoulder Impingement Syndrome?

Repetitive overhead activity — sport, painting, construction. A bony spur narrowing the subacromial space. Weakness of the rotator cuff and shoulder-blade muscles. Poor posture altering the position of the shoulder blade.

How is Shoulder Impingement Syndrome diagnosed?

Specific tests load the shoulder in positions that reproduce the pinch, helping to confirm impingement and distinguish it from a cuff tear. Ultrasound or MRI assesses the tendons and bursa and rules out a tear, while X-rays can reveal a bony spur.

How is Shoulder Impingement Syndrome treated?

The great majority of cases improve with non-surgical care aimed at restoring movement and creating space for the tendons. Physiotherapy: Strengthening the cuff and shoulder-blade muscles restores balanced movement and opens the subacromial space. Anti-inflammatories: Medication and, in selected cases, a targeted injection settle inflammation so rehabilitation can progress. Subacromial decompression: When pain persists despite full rehabilitation, keyhole surgery removes the spur and creates more room for the tendons.

What does recovery involve?

With consistent rehabilitation, most patients improve over several weeks to a few months and return to overhead activity. Where surgery is needed, a structured programme afterwards restores motion and strength, and outcomes are generally very good.
