Wrist tendinitis

　　Injuries, excessive strain, osteoarthritis, some immune diseases, or even infections can trigger this condition. Occupations that require long-term repetitive strain on the joints, such as typists, instrumental musicians, cargo handlers, or those who need to use computers for extended periods, can trigger or exacerbate the disease. Women and diabetics are more prone to this condition. Patients may experience joint pain, morning stiffness, with the sensation of joint stiffness usually being most pronounced upon waking up, and symptoms will not significantly alleviate with frequent movement. The affected joints may swell, even produce a popping sound, and have limited joint mobility.

　　The most common complication of this disease is concomitant tenosynovial stenosis, which is a chronic aseptic inflammation caused by the long-term mechanical friction of tendons within the tenosynovium. The pathological changes mainly involve inflammatory cells in the peritenon tissue, and with the progression of the disease, the collagen fibers of the tendons may degenerate, leading to concomitant tenosynovial stenosis.

　　As urban white bones - senior white bones = white-collar + business backbone + industry elite, long-term use of computers has almost become an unavoidable lifestyle. However, the computer that you rely on every day to work is slowly eating away at your hands. At the end of a day of tense work, when you stretch your arms and move your fingers, have you ever found that there is a hidden pain in the joints of your fingers and wrists? Don't think that this is just overwork of the fingers. It may be that you are suffering from 'keyboard hand'.

　　"Keyboard hand" refers to the wear and inflammation of some finger joints caused by long-term use of keyboards and mice, which is known as "tenosynovitis" in medical terms. As long as the same action is performed repeatedly and with force for a long time, it may cause tenosynovitis in the joints, and pain and restricted movement will arise from this. Daily use of computer keyboards, mice, MP3 players, even sending text messages with a mobile phone, will cause certain fingers to bend and extend repeatedly and with force for a long time, which will cause excessive friction of the tendons in the hand, which is also the "prerequisite" for the formation of tenosynovitis.

　　Office workers often maintain the same posture in front of the computer for a long time, unaware that this has already laid a hidden danger for tenosynovitis, commonly known as 'mouse hand'. Doctors have found that the higher the position of the mouse, the greater the damage to the wrist; the farther the distance from the body, the greater the damage to the shoulder. Therefore, the mouse should be placed at a slightly lower position, which is equivalent to the height of the elbow when the upper arm is perpendicular to the ground in a sitting posture. The position of the keyboard should also be similar. Many computer desks do not have a dedicated position for the mouse, so placing the mouse on the desk for long-term work is self-evidently harmful to people.

　　The distance between the mouse and the body can also be increased because the mouse is placed on the table, and the long-term force is borne by the shoulder and elbow, which is also one of the causes of tenosynovitis. When the angle between the upper arm and the front body is kept below 45 degrees, the distance between the body and the mouse is more appropriate. If it is too far, the forearm will bring the upper arm and shoulder to tilt forward, causing continuous tension in the joints and muscles.

　　If there is numbness, swelling, tingling, decreased sensitivity, or pain upon pressure in the wrist or fingers, joint stiffness, difficulty and weakness in bending fingers to hold objects, or discomfort that worsens with finger movement, these are obvious symptoms of tenosynovitis.

　　If there is numbness, swelling, tingling, decreased sensitivity, or pain upon pressure in the wrist or fingers, joint stiffness, difficulty and weakness in bending fingers to hold objects, or discomfort that worsens with finger movement, these are obvious symptoms of tenosynovitis. If you have tenosynovitis, it is important to seek treatment promptly.

　　1. Prevent excessive use of the thumb, and avoid prolonged squeezing or pushing actions.

　　2. Make full use of the palm to support objects while avoiding using the thumb and fingers to pinch or lift.

　　3. Reduce the use of the thumb for pushing and wiping actions.

　　4. Replace tools that require a lot of strength to捏 with tools with larger handles.

　　5. Avoid picking up heavy objects with the thumb and fingers.

　　6. You can also go to the hospital for physical therapy, acupuncture, and other methods, but the efficacy is hard to say.

　　7. Local injection of hydrocortisone acetate under the guidance of a doctor is very effective

　　Examinations to be done for tenosynovitis of the wrist: Flexor muscle tension test, Extensor muscle tension test

　　1. Local swelling: See the early symptoms of tenosynovitis mentioned above;

　　2. Local tenderness: Local tenderness is obvious around the injured tenosynovitis and surrounding area;

　　3. Positive resistance test: Due to inflammation or swelling of the tendons and sheaths of the affected muscles, pain may worsen when the joint is hyperextended or hyperflexed, such as when the styloid process of the radius is narrow or overflexed, and there will be a positive Finkelstein sign.

　　Eat more vegetables

　　Eat more vegetables, such as rapeseed, green vegetables, celery, etc., and eat more foods rich in protein and calcium, such as lean meat, chicken, eggs, soy milk, etc.

　　Eat more fruit

　　You can eat some oranges, apples, green pears, hawthorn, etc., to supplement vitamins and balance nutrition.

　　Acupuncture Treatment: Acupuncture treatment is very effective for tenosynovitis.

　　Acupuncture takes the root and knot of the meridians as the standard, with the five-shu points and collateral points as the main points, and is prohibited from needling locally.

　　Traditional Chinese medicine explains that tenosynovitis belongs to the category of 'meridian injury' in traditional Chinese medicine, which is caused by overwork in the local area, accumulated labor injury of the tendons, or exposure to cold and coolness, leading to stagnation of Qi and blood, and failure to nourish the tendons and collaterals, resulting in the onset of the disease. Treatment should follow the principles of promoting blood circulation and removing blood stasis, reducing swelling and relieving pain, and needs to drive away the external pathogenic factors of cold and dampness, and also needs to unblock the meridians and collaterals, harmonize Qi and blood, so that the flow of Qi and blood is smooth, the local circulation is improved, and the damaged tissue is repaired, thus achieving the goal of cure.

　　Traditional Chinese medicine believes that tenosynovitis of the wrist is caused by labor injury and meridian injury, or invasion of cold and dampness into the collaterals, causing obstruction of the meridians and collaterals, unsmooth flow of Qi and blood, and stagnation of Qi and blood. Traditional Chinese medicine treatment follows the principles of promoting blood circulation and removing blood stasis, reducing swelling and relieving pain, and needs to drive away the external pathogenic factors of cold and dampness, and also needs to unblock the meridians and collaterals, harmonize Qi and blood, so that the flow of Qi and blood is smooth, the local circulation is improved, the damaged tissue is repaired, and immunity is enhanced to prevent the recurrence of diseases.
