Rotator cuff tendinosis refers to the degeneration or wear-and-tear of the tendons of the rotator cuff in the shoulder. The rotator cuff is a group of four muscles and their tendons that help stabilize and move the shoulder joint. Tendinosis is different from tendinitis, which involves inflammation—tendinosis specifically refers to the chronic degradation or microtears in the tendons without significant inflammation.
Symptoms of Rotator Cuff Tendinosis:
- Pain: Often a dull ache in the shoulder, especially when lifting the arm, reaching overhead, or lifting objects.
- Weakness: Reduced strength in the shoulder and arm, which may make activities like lifting or rotating the arm difficult.
- Limited Range of Motion: Difficulty moving the shoulder freely.
- Pain at Night: Often worse when lying on the affected shoulder.
Causes:
- Aging: As people age, the tendons of the rotator cuff naturally weaken and are more susceptible to injury.
- Overuse: Repetitive overhead activities or heavy lifting can cause microtears in the tendons.
- Poor posture or mechanics: Imbalances in shoulder movement may lead to stress on the rotator cuff.
- Injury: Acute injuries or falls may also contribute to the condition.
Treatment Options:
1. Conservative (Non-surgical) Treatments:
- Rest: Reducing or avoiding activities that strain the shoulder can help the tendons heal.
- Physical Therapy: A tailored exercise program aimed at strengthening the rotator cuff muscles, improving flexibility, and correcting posture.
- Ice and Heat: Applying ice to reduce pain and inflammation and heat to relax the muscles and increase blood flow.
- Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Medications like ibuprofen or naproxen to manage pain and inflammation.
- Corticosteroid Injections: A shot of steroids into the shoulder to reduce inflammation and pain (used in cases with significant discomfort).
2. Surgical Treatments (for severe or chronic cases):
- Arthroscopic Surgery: A minimally invasive surgery where small incisions are made, and a camera (arthroscope) is used to remove damaged tissue or repair tears in the rotator cuff.
- Open Surgery: In more severe cases, open surgery might be needed to repair large tears or significant damage to the tendons.
- Tendon Repair or Reattachment: If the tendons are significantly torn, they may need to be surgically reattached to the bone or repaired using sutures or other methods.
3. Platelet-Rich Plasma (PRP) Injections:
This is an experimental treatment in which the patient’s own blood is processed to concentrate platelets, then injected into the affected area to promote healing and regeneration of the tendon.
4. Regenerative Medicine:
- Stem Cell Therapy: This is another emerging treatment option that involves injecting stem cells into the injured tendon to promote healing.
Preventing Rotator Cuff Tendinosis:
- Strengthening Exercises: Regularly strengthening the rotator cuff muscles can help prevent injuries.
- Proper Technique: Using proper lifting and movement techniques, especially during overhead or repetitive activities.
- Stretching: Keeping the shoulder joint flexible can reduce strain on the tendons.
It’s important to consult with a healthcare professional to determine the best treatment plan based on the severity of the condition. If left untreated, rotator cuff tendinosis can lead to further damage or tears that may require more intensive treatments or surgery.
