Yesterday, I met a young patient who came to the clinic 1.5 years ago with a chronic wrist injury. Two weeks ago, she had wrist pain, which did not improve after self-treatment, and came to me, saying that the old wrist injury had not healed completely and had recurred. I asked about the painful area and examined it. I asked about the pain and examined it, and considered it to be the disease I am going to talk about below. The pain in the wrist is mostly seen in radial stenosis tenosynovitis. A few days ago, my classmate published this topic on WeChat, also known as hug-boy hand, with excellent illustrations and text. I’m not familiar with WeChat, so I’ll talk about some rare wrist pain diseases here! I. Other names: twisted pronation tenosynovitis, babbling peritendinitis, babbling tenosynovitis. The mechanism of pathogenesis: in the dorsal middle and lower 1/3 of the forearm thumb long extensor muscle and thumb short extensor muscle from the radial carpal long extensor muscle, radial carpal short extensor muscle above the diagonal across, there is no tendon membrane, there is only a layer of loose fascia cover, when the thumb or wrist joint long-term frequent activities, the above intersecting tendons rub against each other, causing aseptic inflammation of the tendon and its surrounding fascia. Occurrence group: Mostly seen in carpenters, masons, etc. Longer periods of work beyond endurance are also a cause of periostitis of the wrist extensor tendons. For example, the disease can occur in clerical workers who suddenly change their job type to engage in intense elbow and wrist extension work. Clinical manifestations: swelling, pain, burning, and pressure on the dorsal radial side of the lower and middle forearm. The wrist movement is limited. During examination, the patient can feel the twisting sensation when pressing the swollen and painful area with the thumb and asking the patient to make a fist and do wrist extension and flexion. In mild cases, the pain is localized and there is pressure pain, and there may be no twisting sensation. Treatment: In mild cases, the symptoms can be cured by applying topical medication such as Fotarine cream or reducing activities. In the acute stage, it is generally inappropriate to perform tendon manipulation, but after the swelling has receded a little, light pinching and straightening techniques can be done. Those with painful activities should apply a wrist brake, apply anti-inflammatory and pain-relieving cream or Ruyi Jinhuang ointment, fix the wrist joint including the thumb with cardboard, suspend the affected limb with a triangular scarf for 1 to 2 weeks, remove the external fixation after the twisting sensation disappears, and gradually resume work. During the period, depending on the situation, Chinese and Western medicines can be used internally, and physical therapy such as medium frequency, or local closure can also be used for treatment.
