What is the sheath around a tendon called?
A protective sheath known as the synovium covers tendons. This sheath produces synovial fluid, which keeps the tendon lubricated. Injury to the tendon may result in the malfunction of the sheath. If this occurs, the sheath may fail to make synovial fluid or may not make enough fluid.
How do you treat an inflamed tendon sheath?
How are tendonitis and tenosynovitis treated?

What causes tendon sheath?
Repetitive motion. Knitting or playing video games can lead to tenosynovitis in the sheath that encloses the tendon that runs from your wrist to your thumb.

Does every tendon have a sheath?
However, not all tendons possess true synovial sheaths; these are in fact found only in areas where a sudden change in direction and an increase in friction require very efficient lubrication.
Can you tear a tendon sheath?
In activities that require a lot of a hand strength (e.g., rock climbing), tendons and/or their sheaths can also be stretched or torn. The crimp-grip position of the fingers necessary for rock climbing places a great deal of strain on the pulleys of the tendon sheath and can cause a rupture of the sheath.
Do tendon sheaths heal?
A brace can prevent overuse, which can help your joint, tendon, and tendon sheath recover. If there is a severe injury, surgery may be necessary to repair the joint and allow the tendon sheath and other structures to heal.
Does tenosynovitis require surgery?
