Youthful hump

This disease is also known as "Juvenile Humps" and Scheuermann Disease. The lesions mainly involve the middle and lower thoracic vertebrae. The lesion occurred at the second ossification center of the vertebral body, that is, the sacral plate above and below the vertebral body. For various reasons, the blood supply to the diaphragm is reduced, the cartilage plate is thinner, the pressure is reduced, and fragmentation occurs under excessive load. The nucleus pulposus protrudes into the vertebral body at the rupture, forming a so-called Schmorl nodule. The thoracic segment of the spine is bent backwards, so that the pressure on the front of the vertebral body is greater than that on the rear. Through the doctor's passive movements, humpbacks can be corrected as active humpbacks. Cannot be corrected called fixed hump, such as ankylosing spondylitis.
