Patients who have been diagnosed with tenosynovitis generally do not require radiographic examination, mainly because other soft tissues, including tendons, tendon sheaths, and ligaments, generally do not show significant images on radiographs, so tenosynovitis generally does not require radiographs after diagnosis, while patients who have not been diagnosed with tenosynovitis may require radiographic examination, and generally need to exclude other joint or bone diseases. This is why the test is needed. However, most patients with tenosynovitis can be diagnosed through physical examination and clinical symptoms, and take symptomatic treatment, usually the first choice is local closure therapy, the efficacy is more obvious and fast, and generally after a course of treatment, about 4 times of closure therapy can make the mild to moderate tenosynovitis can be cured. But after the use of closed treatment, must reduce the local limb activities to prevent recurrence of the disease, if after closed treatment, the symptoms are not significantly improved, should be further diagnosed to exclude other diseases.
