Thumb tenosynovitis in children

Tenosynovitis is a relatively common disease, and the impact of this disease on the patient's physical health cannot be ignored. Many children have had tenosynovitis problems since childhood. If you want to completely alleviate this problem and enable your child to recover health as soon as possible, you must actively take certain methods to treat this disease! Here is an introduction to the treatment of tendonitis!

1. Radial styloid stenosing tenosynovitis

The tendon sheath is a double-layer, sleeve-like, closed synovial tube that is wrapped around the tendon. It is a synovial sheath that protects the tendon. It is divided into two layers that wrap around the tendon, and there is a cavity between the two layers, namely the synovial cavity, which contains tendon sheath synovial fluid. The inner layer is closely attached to the tendon, and the outer layer is lined inside the tendon fiber sheath. Together they are combined with the bone surface to fix, protect and lubricate the tendon, protecting it from friction or compression. If the tendon is excessively rubbed here for a long time, damaging inflammation of the tendon and tendon sheath may occur, causing swelling, which is called tenosynovitis. If left untreated, it may develop into permanent disability.

When it is first diagnosed or the symptoms are mild, conservative treatment such as immobilization, physical therapy or local blockade can be used. If non-surgical treatment does not significantly improve symptoms or symptoms recur, surgical treatment can be used. Surgical treatment does not end with cutting open the first sheath on the dorsum of the wrist. The sheath should also be checked for anatomical variations. If there are any, the excess part needs to be removed. If there is tendon adhesion here, it should be released at the same time. Since the superficial branch of the radial nerve and its branches pass subcutaneously here, they should be protected during surgery and not damaged.

2. Stenosing tenosynovitis of the finger flexor tendons

(1) Physical therapy or local blockade can be used when the disease first occurs, and most of them are effective;

(2) Surgery can be used for patients with severe or recurrent lesions. The thickened narrow ring should be removed during surgery. The extent of the removal should be determined by observing that the thickened part of the flexor tendon is not blocked by the sheath when the finger is flexed and extended.

3. Myosinitis

Most symptoms can disappear by immobilizing the wrist, applying local hot compresses, and performing local physical therapy or local blockade when necessary. If the symptoms recur over a long period of time, the peritendinous and synovial tissues become thicker, and local bulges occur, surgical treatment may be considered to remove the thickened synovium and fascia.

4. Ulnar wrist extensor tenosynovitis

In the early stage, immobilization or local closure is required, and in the late stage, synovectomy or partial sheath resection is performed. Similarly, similar symptoms may occur in the radial and ulnar flexor wrist muscles, often caused by corresponding tenosynovitis. If the disease recurs, patients may also consider surgical treatment.
