What is Tendovaginitis?

Tendovaginitis is an often overlooked yet painful condition that affects the tendon sheaths around your wrists and fingers. If you frequently experience wrist pain, stiffness, or snapping sensations during movement, tendovaginitis could be the cause. This inflammation commonly arises from repetitive motions like typing, manual work, or certain sports, making it a frequent problem in today’s busy lifestyles. Knowing the early signs and effective treatments can prevent long-term damage and help you get back to pain-free movement. In this article, we’ll break down what tendovaginitis is, its main symptoms, causes, and the best ways to manage and treat this condition.

What is Tendovaginitis?

Tendovaginitis, also called tenosynovitis, is an inflammation of the protective sheath around your tendons. Tendons connect muscles to bones and allow movement. The tendon sheath is a thin layer filled with lubricating fluid that helps tendons glide smoothly. When this sheath becomes irritated or swollen, it causes pain and stiffness. Tendovaginitis often affects the hands, wrists, and fingers but can happen elsewhere. It is different from tendinitis, which is inflammation of the tendon itself. Understanding this condition is key to recognising symptoms early and getting effective treatment.

How Does Tendovaginitis Develop?

The tendon sheath’s role is to protect tendons from friction during movement. When the sheath is injured or irritated, it can swell and narrow. This narrowing is called stenosis and makes it harder for the tendon to slide through its canal. The friction leads to pain and sometimes a snapping or clicking feeling. Over time, tendovaginitis causes stiffness, weakness, and limited motion in the affected joint. It may develop due to repetitive strain, injury, infection, or autoimmune disease.

Types of Tendovaginitis

There are several types of tendovaginitis, each with unique features. De Quervain’s tendovaginitis affects the thumb side of the wrist. It is common in people who use repetitive thumb motions, like new mothers or office workers. Stenosing tendovaginitis, or trigger finger, causes the fingers or thumb to lock or snap when bent. Infectious tendovaginitis is caused by bacteria and often needs urgent treatment. Noninfectious types are linked to conditions like rheumatoid arthritis or gout.

What Causes Tendovaginitis?

Repetitive movements are a common cause. Tasks like typing, writing, manual labour, and sports can strain tendons and sheaths. Injuries or wounds near a tendon can cause inflammation or infection. Medical conditions such as diabetes, rheumatoid arthritis, and gout increase risk. Age and poor ergonomics also contribute. Being aware of these causes can help you prevent or manage tendovaginitis early.

Causes of Tendovaginitis

• Repetitive hand and wrist movements
  
• Injury or trauma to tendons or sheath
  
• Infection of tendon sheath
  
• Medical conditions like rheumatoid arthritis, diabetes, gout
  
• Poor ergonomics and overuse

Symptoms of Tendovaginitis

Symptoms often start gradually. You may feel a dull ache or pain when moving your wrist or fingers. Swelling, redness, and tenderness around the affected area are common. As it worsens, stiffness and difficulty moving the joint develop. Some experience clicking, snapping, or a “triggering” sensation when bending fingers. Grip strength may lessen, making it harder to hold objects. Severe cases can cause tendon rupture or weakness.

Symptoms of Tendovaginitis

• Pain when moving the joint
  
• Swelling and redness
  
• Tenderness on pressure
  
• Stiffness and limited motion
  
• Clicking or snapping of fingers or thumb
  
• Weak grip strength
  
  

How is Tendovaginitis Diagnosed?

Doctors usually diagnose tendovaginitis through a physical exam. They check for pain when pressing the tendon sheath and assess your range of motion. Imaging tests like ultrasound can detect swelling or thickening of the sheath. X-rays help rule out fractures or other problems. In complex cases, MRI or CT scans provide detailed images. Blood tests may be needed to check for infections or autoimmune causes. Early diagnosis helps tailor effective treatment.

Treatment Options for Tendovaginitis

Most tendovaginitis cases improve with simple measures. Treatment includes:

• Resting the affected tendon and avoiding aggravating activities
  
• Applying ice or heat to reduce pain and swelling
  
• Wearing splints or braces to support the joint
  
• Taking anti-inflammatory medications such as ibuprofen
  
  

If symptoms continue, further treatments include corticosteroid injections to reduce inflammation. Antibiotics are necessary for infections. Hand therapy helps restore motion and strength. Surgery is reserved for severe or persistent cases, releasing tight tendon sheaths to free movement.

Surgical Treatment for Severe Tendovaginitis

Surgery is considered when pain or locking fingers persist despite other treatments. The common procedure is an A1 pulley release, where the surgeon cuts the tight sheath. This frees the tendon to glide smoothly again. The operation is usually done under local anaesthetic and on an outpatient basis. After surgery, gentle finger movements start early to prevent stiffness. Recovery typically takes three to five weeks. Most patients regain full function and strength.

Can Tendovaginitis Return?

Tendovaginitis can recur if repetitive strain continues. Without changing activities or using supports, flare-ups are common. Taking breaks from repetitive tasks and improving ergonomics helps reduce risk. Supports like braces during activity can protect tendons. Managing underlying conditions such as arthritis or diabetes lowers chances of recurrence. Watching for early symptoms and acting quickly improves long-term outcomes.

Preventing Tendovaginitis

Prevention focuses on reducing strain on your tendons. At work, take frequent breaks and use ergonomic equipment. For sports or hobbies, warm up properly and avoid overusing the same movements. Maintain general health by stretching regularly and managing medical conditions. Proper posture and weight control also protect your joints. Preventing tendovaginitis is easier than treating it after it develops.

Living With Tendovaginitis

Living with tendovaginitis requires patience and care. Follow your doctor’s instructions and avoid pushing through pain. Early treatment usually leads to full recovery. If symptoms persist beyond a few weeks or you notice signs of infection such as redness, swelling, fever, or discharge, seek medical help promptly. Taking care of yourself can prevent complications and speed your return to normal activities.

Tendovaginitis vs. Other Hand Conditions

Tendovaginitis differs from conditions like carpal tunnel syndrome, which mainly affects nerves causing numbness. Tendinitis involves inflammation of the tendon itself, not the sheath. Proper diagnosis helps avoid confusion and ensures the right treatment. If you have pain or difficulty moving your hands or wrists, see a specialist for an accurate assessment.

Products That Can Help

To help manage tendovaginitis symptoms and support healing, consider using specialised products like the ErgoThumb Spica Splint, which provides targeted support for thumb and wrist conditions such as De Quervain’s and trigger thumb. The TFCC Support Wrist Brace offers stability for ulnar-sided wrist pain, helping to reduce strain and promote recovery. For general wrist support, the Performance Wrist Brace is lightweight and adjustable, ideal for relieving discomfort from repetitive strain and protecting the wrist during activities. Using these braces alongside rest and medical treatment can significantly improve comfort and aid recovery.

Conclusion

Tendovaginitis can cause significant discomfort, but with early recognition and proper care, most people recover fully. Paying attention to symptoms and using the right treatments helps restore pain-free movement. Taking steps to reduce strain and support your tendons is key to preventing future problems.
