Overview

What is Stenosing Tenosynovitis?

Stenosing tenosynovitis is a particular form of tenosynovitis. The word stenosis comes from the Greek word and means narrowing. When there is a condition of stenosing tenosynovitis, it indicates that inflammation has taken place in a tendon which now no longer slides smoothly over a narrow area of the body.

If you ever have dressed warmly in winter, it feels just like the struggle to insert an arm into your jacket sleeve when you have extra layers on. It may not lodge inside, but getting it in is tricky compared to normal times.

What are the different kinds of stenosing tenosynovitis?

There are various types of stenosing tenosynovitis, including:

Trigger finger: Trigger finger involves irritation of the sheath that regulates and leads the tendons in the fingers and thumb. Most people experiencing trigger finger can feel a kind of catch or bump as they bend the affected finger.
De Quervain's tendinosis: De Quervain's tendinosis is an inflamed pain in the tendons where your thumb is. It is also called radial styloid tenosynovitis and will come in with pain on the backside of your wrist along your thumb.
Peroneal tenosynovitis: On each side of your ankles, you have peroneal tendons that can be affected by stenosing tenosynovitis should their synovial membrane become inflamed.
Forearm tenosynovitis: The tendons surrounding your forearm-extensor carpi ulnaris, extensor carpi radialis, and extensor digitorum communis-can also be involved in stenosing tenosynovitis.

Regardless of the condition you may have, if you are experiencing pain or you cannot move a part of your body as well as you would like to, see your health professional.

What are the symptoms of Stenosing Tenosynovitis?

The symptoms of tenosynovitis may include:

Pain.
Inflammation at a joint.
Inability to perform normal movement of a limb or any body part.
Pain with movement of an affected part.
Discoloration arranged in a straight line along a tendon.

What causes Stenosing Tenosynovitis?

Causes of tenosynovitis include:

Autoimmune diseases: Any disease in which your body's defense mechanisms attack itself leads to damage to the synovial membrane. Diseases that cause tenosynovitis include arthritis, such as rheumatoid arthritis and gout, and diabetes.
Overuse: Typically, overuse syndrome pertains to the repeated movement or motion during prolonged periods. Injuries associated with overuse syndrome occur quite frequently through tenosynovitis.
Infections: All common infections can spread to your synovial membrane and thus cause infectious tenosynovitis.
Trauma: Any form of injury or accident that damages your tendons or the area around them can trigger tenosynovitis.

What is the diagnosis of Stenosing Tenosynovitis?

Your doctor will examine you physically to determine if you have tenosynovitis. They will look at the severity of your symptoms and how much your range of motion (how far you can move a part of your body) has been affected. They may also ask for other blood tests or labs to rule out infections.

What tests will be done to diagnose Stenosing Tenosynovitis?

After your physical examination, you may need one of the following tests:

X-rays
Magnetic Resonance Imaging (MRI)
CT scan

What are the treatments of Stenosing Tenosynovitis?

Some people may experience spontaneous resolution of trigger finger, which does not require treatment.

If it is not treated, the finger or thumb affected might permanently bend, making everyday activities challenging.

When treatment is necessary, there are several options, such as:

Rest: Avoiding certain movements and activities.
Medications: NSAIDs can be taken to provide relief from pain.
Splinting: This is holding the injured finger against a plastic splint in position to immobilize it.
Surgery on the traumatized hand: Surgery can enable the affected tendon to move about again.

It is only used if the treatment offered previously has failed. It is effective 100%, although if you do a manual job, you will need to take off for 2 to 4 weeks to work at capacity.

What medications are used to treat Stenosing Tenosynovitis?

It has also been dependent upon what may be causing it. Therefore, what kind of medications one may need to take depends on what is causing tenosynovitis. Some of the medications prescribed include the following:

Antibiotics: In case your tenosynovitis is caused by an infection, then you should be given antibiotics.
NSAIDs: Over-the-counter NSAIDs, such as aspirin or ibuprofen, help to reduce pain and inflammation.
Corticosteroids: Your doctor will probably give you an injection of anti-inflammatory corticosteroids.

What are the risk factors?

Some of the risk factors include:

Frequent grasping: Working or hobbies that involve intense hand use and sustained gripping increase the susceptibility to acquiring trigger finger.
Certain medical conditions: People who have diabetes or rheumatoid arthritis are at an increased risk of developing trigger finger.
Your gender: Trigger finger is more common in women.

What is the complication of Stenosing Tenosynovitis?

Due to a trigger finger, it could also become very challenging for a person to type, button a shirt, or put a key into a lock. It can also affect one's grip on the steering wheel and tools.

How can I prevent my risk of Stenosing Tenosynovitis?

You can help avoid tenosynovitis by not overusing your tendons. Give your body time to recover after workouts, sports jobs or other activities that may require repetitions-for example, using your arms, hands, and fingers for the same actions repeatedly.

You also minimize the strain on your body, including your tendons, by wearing proper safety equipment and exercising safely.

What can I expect if I have Stenosing Tenosynovitis?

Full recovery from tenosynovitis can be expected. If it is caused by a bacterial infection, it is associated with higher risks of complications, and the time of healing will be much longer.
