Symptoms of tenosynovitis of the arm

summary

Tendon sheath is a double-layer sleeve like closed synovial tube, which is the synovial sheath to protect tendon. It is divided into two layers around the tendon, a cavity between the two layers, namely the synovial cavity, in which there is the 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, which is combined with the bone surface to fix, protect and lubricate the tendon and prevent it from friction or compression. Tendon long-term excessive friction here, can occur tendon and tendon sheath injury inflammation, cause swelling, known as tenosynovitis. If not treated, it may develop into permanent inconvenience.

It is one of the causes of ulnar pain of wrist joint. The tendon and sheath of extensor carpi ulnaris play an important role in supporting the distal radioulnar joint and carpal triangle fibrocartilage complex. When the wrist activity is too large, because of repeated traction or sprain, it can induce ulnar pain, especially when exerting.
