“…As far as we know, this is the rst investigation to analyze the relationship between FO and FT and CSR based on more accurate and practical measuring methods on 3-dimentional views. In this work, middle-aged participants (aged from 30-65 years) were included because various con icting factors might interfere nal results in elderly individuals [26,36,37].…”

Background Facet parameters, such as facet orientation (FO) and tropism (FT) are thought to be predisposing factors for pathological changes in the lumbar spine. This study aimed to explore the association between facet parameters and cervical spondylotic radiculopathy (CSR) on 3-dimentional views. Methods A total of 226 patients with single-level CSR and 182 normal control participants were included. FO, FT and the incidence of FT (defined as FT ≥ 7) based on reconstructed CT images were measured. Univariate and multiple logistic regression analysis were used to investigate the association between facet joint parameters and the incidence of CSR. The Pearson Chi-square test was used to find out the relationship between the side of herniation and facet joint parameters in CSR patients. Results Axial FT of CSR group was significantly larger compared to control group at each spinal level, while sagittal except C5/6 and coronal FT shown not. The differences of incidence of axial FT at all levels between groups were statistically significant, as well as incidence of sagittal FT at C4/5 and C5/6. Incidence of axial FT with respect to all levels was significantly associated with CSR, and incidence of sagittal FT only at C4/5 and C5/6 was associated with CSR. The proportion between the left and right side of greater FO was significantly different on axial view. Conclusion Axial and sagittal FT but not FO were associated with CSR, and axial FT might exert more dominant function on the development of CSR. Moreover, CSR might be more vulnerable to more severe axial FT, which should be paid more attention. The side of herniation might prefer the side of greater axial FO.

Study Design. A retrospective case–control study. Objective. Investigating the correlation between the facet tropism (FT) and subaxial cervical disc herniation (CDH). Summary of Background Data. Although debatable, it was widely reported that FT was associated with lumbar disc herniation. However, the exact correlation between FT and subaxial CDH is still unclear. Methods. Two-hundred patients with any disc herniation at C3/4, C4/5, C5/6, or C6/7 and 50 normal participants without CDH (normal control group) were included in this study. For patients, the cervical levels with CDH and the levels without herniation were classified into the “herniation group” and “patient control group,” respectively. Bilateral facet joint angles at C3/4, C4/5, C5/6, and C6/7 on sagittal, axial, and coronal planes were measured on computed tomography (CT). The disc degeneration at each level was assessed on magnetic resonance imaging (MRI). Results. Both the mean difference between left and right facet angles and tropism incidence in herniation group were significantly greater than those in two control groups whenever at C3/4, C4/5, C5/6, or C6/7 level and whenever on sagittal, axial, or coronal plane. The mean differences of angles and tropism incidences in most patient control groups were not significantly greater than those of corresponding normal control groups. The incidence of greater facet angle at the left or right side was not significantly different among the left, central, and right herniation groups. The mean disc degeneration grades in both herniation and patient control groups were significantly higher than those in normal control groups while no difference between herniation and patient control groups. Conclusion. The FT on the sagittal, axial, and coronal planes are all associated with CDH in the subaxial cervical spine. The greater facet angle at the left or right side does not affect the side of herniation. The severity of cervical disc degeneration is not associated with FT. Level of Evidence: 3

The article discusses the main causes of development and clinical features of the instability of the cervical spine in children of different ages. A clinical and instrumental study of 146 children was carried out to determine the relationship between dysplastic instability of the cervical spine and clinical manifestations of neuroorthopedic pathology. Risk factors for the formation of undifferentiated connective tissue dysplasia (UCTD) were identified, signs of osteoligamentous dysplasia on radiographs of the cervical spine and external phenotypic osteoarticular and muscle signs of UCTD in children with instability of the cervical spine were identified. Predicting the development of connective tissue dysplasia before the birth of a child with preventive measures, as well as early diagnosis of pathological conditions and timely treatment will prevent the formation of chronic somatic, neurological and orthopedic diseases.
