Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to an intraoperative coronal balance assessment tool for a spinal column.
Background
Scoliosis, also known as scoliosis, is a three-dimensional deformity of the spine, including abnormalities in the sequence of coronal, sagittal and axial positions.
Scoliosis deformity is particularly indicated in the deviation of the spine in the coronal position, mild scoliosis can be observed, and severe ones need surgical treatment. Scoliosis deformity is a common disease endangering adolescents and children, and is mainly discovered and treated early. Along with the improvement of the operation level, more and more scoliosis malformed patients are fixed and treated by posterior pedicle screw fixation and osteotomy orthopedic bone grafting fusion internal fixation, along with the development of instruments, the orthopedic effect of the operation gradually becomes better, but the incidence of the scoliosis malformation is still higher, and the scoliosis malformation can influence the living quality of the patients to a certain extent. In specific practice, it is often necessary to evaluate the coronal plane balance of a scoliosis patient, specifically when the distance between the perpendicular bisector of the anterior superior iliac spine connecting line and the spinous process of the C7 vertebral body is greater than 20mm, it is determined that the coronal plane of the vertebral column is unbalanced, i.e. a significant trunk deviation occurs. Therefore, evaluating the equilibrium state of the coronal plane of the spine can determine to some extent the severity of the scoliotic deformity and the damage to the human body. More importantly, the equilibrium state of the coronal part of the spine in the orthopedic operation and after the operation is an important evaluation index for the orthopedic curative effect of the spine operation; meanwhile, the method is one of the measurement standards for satisfaction of the appearance and the function of the patient after the operation.
Although the related research of the coronal position is controversial and is ignored by the same general public to some extent, a lot of researches show that the unbalance of the coronal position also affects the mobility and the quality of life of scoliosis patients, so that the assessment of the coronal position balance in the operation is important, and the traditional assessment in the operation only depends on intraoperative fluoroscopy, visual observation and experience estimation, and the method has great error; some are by T-stands, which are generally a relatively reliable choice, but have the disadvantage that: (1) When facing to the patients with partial lower limbs of unequal length or asymmetric pelvis, the method is more complicated, the pelvis inclination of the coronal X-ray pelvis of the standing position needs to be continuously compared, and the X-ray pelvis inclination is continuously adjusted and matched in the operation, and the repeated determination of the left and right sides causes the head of the operator to be bent; (2) A slight angular error of the "T-frame" base has the effect of magnifying the distance, and a 1 ° error at the sacral pelvis will cause C7 to deviate from the sacral midline (CSVL) by a distance (CBD) of about 1 cm.
