Strictly speaking, spine surgery belongs to a subspecialty within orthopaedics, which includes joints, spine, trauma, hand, foot and ankle, sports medicine, pediatric orthopaedics, orthopaedic oncology and other sub-specialties, and is a collection of various sub-specialties. In large tertiary hospitals or larger orthopaedic hospitals, the specialty classification is very fine, and each subspecialty will be independently formed into a department, so as to achieve the purpose of specializing in specialized diseases and the development of the discipline is more professional and more accurate. Therefore, spinal surgery is a subspecialty of orthopedics, relatively more in-depth in the direction of specialization, including the spine, spinal nerves, ligaments, muscles and other related diseases. In many smaller hospitals, it is not separated out.
