Subacromial Impingement Syndrome

Subacromial impingement syndrome occurs when the tendons of the rotator cuff become pinched under the acromion. This common shoulder condition often affects athletes and individuals engaged in repetitive overhead activities.

Quick Facts

  • Condition: Compression of rotator cuff tendons.
  • Common symptoms: Pain during overhead motion, weakness.
  • Risk factors: Repetitive strain, poor posture, anatomical variations.
  • Diagnosis tools: Physical examination, MRI, X-ray.
  • Treatments: Physical therapy, corticosteroid injections, surgery.
  • Rehabilitation focus: Strengthen rotator cuff muscles, improve posture.

Anatomy & Condition

The subacromial space is located between the acromion and the rotator cuff tendons. Narrowing of this space leads to impingement, causing pain and inflammation during movement.

Symptoms & Causes

Patients often report sharp or aching pain in the shoulder, especially during lifting or overhead activities. Causes include repetitive strain, structural abnormalities of the acromion, and inflammation of the surrounding tissues.

Treatment & Recovery

Treatment begins with conservative measures like physical therapy and anti-inflammatory medications. Severe cases may require surgical intervention, such as acromioplasty, to widen the subacromial space.

FAQ

Can impingement resolve without surgery?

Yes, many cases improve with physiotherapy and proper management.

How can I prevent recurrence?

Strengthening shoulder muscles and maintaining good posture can reduce risk.
