Technical Field
The invention relates to the technical field of medical instruments, in particular to a fine adjustment device of a lumbar vertebra fixator.
Background
Scoliosis, commonly referred to as scoliosis, is a three-dimensional deformity of the spine that includes sequence abnormalities in the coronal, sagittal, and axial positions. The normal human spine should be a straight line as viewed from the back, and the torso is bilaterally symmetrical. If the shoulders are not high in the front view or the back is not flat, the scoliosis is suspected. At this time, the whole spine X-ray film in the standing position is photographed, and if the positive X-ray film shows that the spine has lateral curvature of more than 10 degrees, the scoliosis can be diagnosed. Mild scoliosis is usually without significant discomfort and no apparent somatic deformity is visible in appearance. A severe scoliosis may affect the growth and development of infants and teenagers, deform the body, and severely affect the cardio-pulmonary function and even involve the spinal cord, resulting in paralysis. Mild scoliosis can be observed and severe ones require surgical treatment. Scoliosis is a common disease which endangers adolescents and children, and the key is early discovery and early treatment.
