As a “newbie” mother and father or grandparents or grandma and grandpa, every day to hold the baby, help the baby bath, but also stir-fry, wash diapers, cleaning, etc., a long time with the wrist posture is not correct and overworked, pain is easy to appear. The initial symptoms are often masked by the happiness of raising a baby, and only when it becomes too serious to “serve” the baby, do you realize that you need to see a doctor. What is wrong with it? This disease is radial stenosis tenosynovitis, and in fact it is not exclusive to newbies with children, but can also occur in professions that use their wrists for long periods of time, such as typists, chefs, and restaurant waiters. Clinical manifestations Slow onset of limited pain at the wrist joint below the thumb (i.e., radial styloid process), with a few appearing suddenly; sometimes radiating to the hand, elbow, or even shoulder, with pain increasing when moving the wrist or thumb; patients often have limited ability to extend the thumb or lift the wrist due to pain. Self-judgment The painful area has obvious limited pressure pain, and sometimes a hard node can be palpated; the grip thumb ruler deviation test can assist in the diagnosis: the thumb is flexed in the palm, the remaining four fingers grip the thumb, and the wrist is tilted in the direction of the little finger, and severe pain appears to suggest the disease. Pathological changes There is a small shallow and narrow bony groove at the radial styloid process, covered with a thick layer of ligaments, which together form a narrow channel; the two tendons controlling the thumb pass through it, folding into a certain angle and ending at the thumb bone; when the wrist and thumb move, the folding angle increases, resulting in increased friction between the tendon and the surrounding sheath, and over time, aseptic inflammation and swelling occur, and the originally unspacious channel becomes more narrow, i.e., forming a stenosis. In time, aseptic inflammation and swelling occur, and the originally unspacious channels become more narrow, resulting in stenosing tenosynovitis. Treatment The first step is to reduce hand activity, especially to avoid pain-inducing movements until the pain is completely relieved; if necessary, wear a brace to keep the thumb and arm fixed in the same line for 4-6 weeks; when the pain is sudden, you can apply a cold compress for 15 minutes, 4-6 times a day, and after a few days, change to a hot compress for 30 minutes, 4-6 times a day. At the same time, you can try other physical therapy such as shock wave. If the above measures have no obvious effect, local injection of hormone can be made once or twice for closure treatment; patients whose effect is still unsatisfactory, surgery can be considered.
