Symptoms of tenosynovitis of the arm

It often occurs in the thumb, middle finger and ring finger, and the onset age is generally over 40 years old. In the early stage of onset, there is a snapping and pain when the fingers bend and stretch, so it is also called "trigger finger". Patients often report joint mobility is not flexible, joint swelling. In severe cases, the joint is locked in flexion or extension position, and the joint cannot be extended or flexed.

This disease is occasionally seen in children, bilateral thumb in flexion position, can not actively straighten. The light one can straighten the thumb by local massage when the child is asleep, and the heavy one can't straighten the thumb passively. It is also called rubella myosheath inflammation. When wrist activity increased, swelling, fever and local tenderness appeared on the proximal side of the dorsal wrist, which could produce twisting or snow stepping.

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. It is one of the causes of ulnar pain of wrist joint.
