Whether or not the cervical curvature can be restored is determined by a number of factors. If it is due to functional reasons, most of them can be restored; if pathological changes have already occurred, it is often more difficult to restore. 1. Functional changes: Most of the straightening of the cervical spine is caused by long-term postural errors or prolonged standing and sitting, which may lead to tension, fatigue, or aseptic inflammation of the cervical myofascia. If the bones of adolescents or children are not completely shaped, most of the normal curvature can be restored after timely correction. 2. Pathological changes: Some patients may experience straightening of the cervical vertebral physiological curvature due to cervical spine degenerative diseases. Degenerative diseases may lead to cervical vertebral bone hyperplasia, cervical intervertebral disc dehydration, and hypertrophy or calcification of the collateral ligament, which are pathologically altered, and most of them cannot be restored to their original state through conventional means or surgical treatments. If the cervical spine physiological curvature is straightened, it is recommended to carry out standardized treatment as soon as possible in order to reduce the adverse effects of the disease.
