The difference between pain medicine and orthopedics is mainly reflected in the following aspects: 1, the scope of treatment of diseases are different. As the name implies, pain medicine mainly targets diseases that can cause pain in various parts of the body, such as orthopedics, rheumatology, neurology, neurosurgery and other related diseases. However, the diseases treated by this type of department focus on the main symptom of pain. In contrast, orthopedics treats all diseases related to the locomotor system, which means that it is not limited to pain. 2. There are differences in the methods of treatment. The main treatment method of pain-related diseases in pain medicine is mainly conservative treatment, while minimally invasive surgical treatment can be used. Orthopedics, on the other hand, can use both conservative and surgical treatment methods in the treatment of related diseases. 3. Differences in the hierarchy of disciplines. This difference is only in academic terms. Because orthopedics is a secondary department under the Department of Surgery, while pain medicine is a crossover department that has emerged in recent years, its rank may be below that of orthopedics.
