Closure as a conventional treatment method has been widely used in the treatment of many orthopedic diseases. However, many patients always feel very nervous when they hear the need for closure, because they do not understand its treatment mechanism on the one hand, and worry about the side effects of the injection on the other. Next, we will understand, “closed” is actually good or bad. “Closed”, what exactly is the fight? Closed refers to a certain proportion of mixed glucocorticoids and local anesthetics, the drug is injected into the pain site, joint capsule and other lesion areas, to relieve local sterile inflammation, rapid analgesia, release muscle spasm and other effects. “Closed”, will not be “addicted”? The closed injection can effectively relieve acute pain, so many patients worry that they rely on such hormonal drugs need to “fight again and again”, simply can not be cured. Indeed, the closed needle drug contains hormonal components, if long-term, large doses of repeatedly playing closed, there may be osteoporosis, affecting local soft tissue, causing local infection and other side effects. But patients do not have to worry too much, the general doctor will be based on the patient’s own situation to determine the course of closed treatment, generally follow at least a week to a month interval ranging from the principle that the number of consecutive injections should not be too many. After the course of treatment, if the pain is still not relieved, patients are not recommended to continue to use closed treatment, should be further examined, the cause of treatment. What diseases can be treated by “playing closed”? Most soft tissue diseases with chronic strain, such as: frozen shoulder, tennis elbow, tenosynovitis, lumbar muscle strain, lumbar supraspinous ligament injury, interspinous ligament injury, 3rd lumbar transverse process syndrome, lumbar disc herniation and various bursitis, etc. Why does it recur after the course of treatment? Although closure in the treatment of most diseases only plays a role in relieving pain, and cannot play a radical effect. However, there are still many patients with chronic pain in the clinic, after the closure treatment, the symptoms can completely disappear and no recurrence. Therefore, you can not absolutely think that the closure can not cure the disease. After the injection, the doctor will advise the patient to limit the relevant exercise and let the strained area rest for more than a month. However, some patients, after the pain disappears, think they are cured, often do not follow the doctor’s advice, resume the regular movement pattern, repeatedly repeatedly stimulate the original lesion, resulting in the recurrence of the injury. Finally, I hope that you can understand the closure, do not resist too much, and give you more options for your treatment.
