1.Where has wrist arthroscopy been performed so far? Although wrist arthroscopy has been routinely performed in leading foreign medical institutions, it is still in the initial development stage in China in general. At present, there are few institutions that systematically perform wrist arthroscopy, mainly in Beijing, Shanghai, Guangdong, Jiangsu, Zhejiang, Hebei and Sichuan, but some other provinces also have medical institutions that have performed earlier in this field. You can search for the specific hospital that is carrying out the procedure on such websites. 2.What tests are needed before doing wrist arthroscopy? There are various causes of wrist pain. Before deciding whether surgery is needed, the most important thing is to have a physical examination of the wrist joint in person. This is the most critical and difficult step in making a diagnosis for a wrist disorder. Depending on the physical examination, it may be necessary to combine X-rays and, if necessary, MRI and CT films of the wrist joint to determine the diagnosis, and to determine the diagnosis so that we can know how to choose the treatment, whether surgery is needed, and what the costs are. 3. Do these tests vary greatly from hospital to hospital? Is it possible for patients to be examined in advance at the local hospital? Generally speaking, the in-person physical examination of the wrist is the part that requires the most experience of the doctor and is also the most difficult and important part for diagnosis and treatment. The diagnosis of the patient’s condition and the development of an accurate surgical plan cannot be made without a careful in-person physical examination. X-rays generally do not vary much from hospital to hospital, and except for special requirements, in most cases they can be taken at the nearest hospital that is convenient for you and brought in for consultation. However, CT examinations of the wrist joint, especially if you need to check the fracture or healing of the navicular bone, require a special CT scan of the long axis of the navicular bone, which is not routinely done in most hospitals. MRI of the wrist is mainly used to observe soft tissue injuries and lesions, and the soft tissue structures such as the ligamentous cartilage of the wrist are very delicate, so the quality of the MRI film is very high, usually preferably a 3.0T high-definition MRI with a special wrist coil for scanning. Therefore, in most cases I will ask the patient to have the MRI scan at a facility that I know can take such clear MRI films, otherwise there is a risk of having this test for nothing. Many times I encounter patients in the clinic who have had an MRI done locally at considerable expense and have to have it done again because the image quality is not good enough to help with the diagnosis.
