In the outpatient clinic, it is common to see female patients in their 50s and 60s complaining of wrist pain, which sometimes radiates to the fingers and forearms. After prolonged activity, the local temperature increases or there is burning pain, and even late at night often woke up with pain. There is weakness of the wrist when lifting and carrying objects, and occasionally there is a loss of hand. Sometimes weakness and awkward movement of the thumb also occurs. Extension and rotation of the wrist is limited and sometimes rattling may occur. Over time, the range of motion of the affected wrist is further reduced. The strength of the hand to flex the wrist also decreases, and the patient is unable to lift and carry excessively heavy objects. Further investigation of the condition reveals that these people often work at home doing childcare, laundry and cooking. Tendinitis can be caused by injury, overstrain (especially in the hands and fingers), osteoarthritis, some immune disorders, and even infection. The treatment of tenosynovitis is aimed at reducing pain and inflammation, and restoring the function of the limb through rest, braking, and applying warm compresses to the affected area. Medications include oral non-steroidal anti-inflammatory medications and topical anti-inflammatory ointments. Physical therapy (e.g., laser or ultrasound and stretching exercises). In addition, local steroid injections may also be effective in some patients. If this does not work, surgery to remove the stenotic tendon sheath may be considered.
