title: THE INFLUENCE OF POSTERIOR APPROACH CERVICAL INTRASPINAL TUMOR RESECTION ON THE STABILITY OF CERVICAL VERTEBRA.
abstract: This paper discusses the influence of posterior approach cervical intraspinal tumor resection on the stability of cervical vertebra. A total of 32 patients with cervical intraspinal tumor were included and divided into a group undergoing posterior approach bilateral vertebral lamina resection (group A) (n=16) and a group undergoing posterior approach semi-laminectomy (group B) (n=16). It was found, through follow-up visits, that the incidence rate of cervical instability of the patients was 25% and the incidence rate of cervical curvature deterioration of the patients was 37.5% in group A, whereas the two incidence rates of group B were 6.25% and 12.5% respectively; the incidence rates of cervical curvature deterioration and instability were significantly increased compared to group B (P< 0.05). It is concluded that, both regular posterior approach vertebral lamina resection and semi-laminectomy influence the biomechanical change of cervical vertebra, but the influence of the latter is less. Also, it is found that, applying titanium connectors and titanium nails for rigid internal fixation maintains the completeness and stability of the structure of the cervical vertebra.
