Rotator Cuff Injury: Symptoms, Diagnosis, Treatment, and Prevention

Key Takeaways

  • The supraspinatus tendon tears most frequently due to its poor blood supply and location beneath the acromion bone, where it gets pinched during overhead movements.
  • Pain that worsens at night and prevents sleeping on the affected side is often the first sign, occurring before significant weakness develops.
  • Partial tears affect 25% of people over age 60 and may heal with 6-12 weeks of physical therapy, while full-thickness tears typically require surgical repair within 6 months to prevent muscle atrophy.
  • Workers in overhead occupations like painters, carpenters, and tennis players have a 3-fold higher risk of injury compared to sedentary workers.
  • Strengthening exercises targeting the posterior deltoid and rhomboids can reduce injury risk by 40% when performed 3 times weekly for 8 weeks.

The rotator cuff is a group of muscles and tendons that stabilize your shoulder joint and allow you to move your arm. Injuries to the rotator cuff can cause pain, weakness, and limited range of motion. In this article, we'll explore the causes, symptoms, diagnosis, treatment, and prevention of rotator cuff injuries.

What Is the Rotator Cuff?

The rotator cuff consists of four muscles and their tendons: supraspinatus, infraspinatus, teres minor, and subscapularis. These muscles attach your upper arm bone (humerus) to your shoulder blade (scapula), forming a cuff-like structure. The rotator cuff helps you lift and rotate your arm, enabling you to perform daily activities and participate in sports.

Common Rotator Cuff Injuries

Rotator cuff injuries can occur due to overuse, repetitive motions, or sudden trauma. The most common types of rotator cuff injuries include:

  • Rotator cuff tear: A partial or complete tear in one or more of the tendons that attach the rotator cuff muscles to the humerus.

  • Tendinopathy: Inflammation or irritation of the rotator cuff tendons, often caused by repetitive stress or overuse.

  • Bursitis: Inflammation of the bursa, a fluid-filled sac that cushions the rotator cuff tendons, usually due to repetitive motions or infection.

Symptoms of Rotator Cuff Injuries

If you have a rotator cuff injury, you may experience the following symptoms:

  • Dull pain in your shoulder, especially when reaching overhead or behind your back

  • Weakness in your arm

  • Difficulty sleeping due to shoulder pain

  • Grinding or crackling sensations when moving your shoulder

  • Limited range of motion in your arm

Rotator Cuff Injury: Symptoms, Diagnosis, Treatment, and Prevention

Diagnosing Rotator Cuff Injuries

To diagnose a rotator cuff injury, your doctor will perform a physical examination, moving your arm and pressing on your shoulder to assess pain and strength. Imaging tests, such as X-rays, ultrasound, or MRI, may be used to visualize the soft tissues and structures of your shoulder.

Treating Rotator Cuff Injuries

Most rotator cuff injuries improve with conservative treatment, which may include:

  • Rest and avoiding activities that aggravate your shoulder pain

  • Applying ice and heat to reduce pain and inflammation

  • Taking over-the-counter pain relievers, such as ibuprofen or naproxen

  • Participating in physical therapy to stretch and strengthen your shoulder muscles

  • Receiving steroid injections to provide short-term pain relief

In some cases, surgery may be necessary to repair a torn rotator cuff tendon or rebuild the shoulder joint. Your doctor will recommend the best treatment approach based on the severity of your injury, age, overall health, and activity level.

Preventing Rotator Cuff Injuries

To reduce your risk of developing a rotator cuff injury or re-injuring your shoulder after treatment, follow these prevention tips:

  • Maintain good posture and avoid holding heavy objects away from your body

  • Strengthen the muscles in your shoulder, upper back, and arms with targeted exercises

  • Stretch your shoulder muscles regularly to improve flexibility and reduce stiffness

  • Use proper form when participating in sports or activities that involve overhead arm movements

Consult with your doctor or a physical therapist to develop a personalized exercise program that addresses your specific needs and goals. By taking steps to protect and strengthen your rotator cuff, you can minimize your risk of injury and maintain optimal shoulder health.

The Bottom Line

Most rotator cuff injuries respond well to conservative treatment when caught early, but delaying care can lead to irreversible muscle damage requiring complex surgery. The key is distinguishing between minor strain and significant tears through proper evaluation. If you're experiencing persistent shoulder pain or weakness that interferes with daily activities, Doctronic can help you understand your symptoms and determine the right next steps.
