Definition
Tenosynovitis is an inflammation of the tissue that covers a tendon. Tendons are cords that connect bones to muscles. It is most common in the hand, wrist, and foot.
Causes
Common causes are:
- Injury
- Infection
- Strain
-
Repetitive motions
Risk Factors
Things that may raise the risk of this problem are:
- Jobs, sports, or activities that involve repetitive motion
-
Diseases that cause inflammation, such as
gout
and
rheumatoid arthritis
Symptoms
Problems may be swelling and pain, especially with motion.
Diagnosis
The doctor will ask about your symptoms and health history. A physical exam will be done. It will focus on the painful tendon. This is often enough to make the diagnosis. Imaging tests may be done to confirm it.
A blood test may also be done to look for signs of infection.
Treatment
The goal of treatment is to ease pain and swelling. This will make it easier to move. Options may be:
- A brace or splint to prevent motion
- Exercises to help with strength, flexibility, and range of motion
- Medicine to ease pain and swelling
- Antibiotics to treat any infection
Surgery
Surgery may be done if other methods do not help. The surgery will release the tendon and allow it to move freely.
Prevention
To lower the risk of tenosynovitis:
- Take breaks from activities.
- Adjust workspaces to minimize the strain on joints.
