What is radial tenosynovitis

summary

My job is to work in front of the computer every day, and my fingers keep knocking on the keyboard every day. I found that my fingers are swollen these days. I didn't care much about it, but later it became more and more painful. I saw the doctor and said it was tenosynovitis. Now let's talk about what is radial tenosynovitis.

What is radial tenosynovitis

First, the tendon sheath is a double-layer sleeve like closed synovial tube, which is the synovial sheath to protect the tendon. It is divided into two layers around the tendon, there is a cavity between the two layers, namely the synovial cavity, in which there is synovial fluid of tendon sheath. The inner layer is closely attached to the tendon, and the outer layer is lined in the tendon fiber sheath to heal with the bone surface, which has the function of fixing, protecting and lubricating the tendon from friction or compression.

Second, stenosing tenosynovitis of radial styloid process is caused by frequent thumb or wrist activities, which makes extensor pollicis brevis and abductor pollicis longus rub each other repeatedly in the sheath of radial styloid process for a long time, resulting in aseptic inflammatory reaction between tendon and sheath, local exudation, edema and fibrosis, thickening of sheath wall, local thickening of tendon, and obstruction of tendon sliding in sheath The clinical symptoms of the disease.

Third: the treatment of this disease can be used to puncture or hit, pressure, squeeze through the wall of the capsule, the capsule liquid into the subcutaneous, waiting for its self absorption. Thick needle can also be used to draw out the colloidal sac fluid and inject cortisone drugs, which can temporarily relieve symptoms and is easy to relapse. If necessary, the cyst can be removed by operation. If the removal is not thorough enough, there is the possibility of recurrence after operation.

Radial tenosynovitis is generally easy to find in the early stage. After finding and confirming the disease, we need to pay attention to rest, avoid local activities and cold. We can paste some plaster for promoting blood circulation and removing blood stasis locally. After treatment, we still need to pay attention to continuous observation.
