Abstract

Abstract:

BACKGROUND: Normal sagittal balance of cervical spine is the key to cervical spine orthopedic surgery. As the complexity of the anatomical structure and physiological function of the cervical spine, accurate measurement of sagittal balance parameters and correlation between parameters become an important reference for preoperative planning and postoperative evaluation of curative effect. Current research focuses on patients with clinical symptoms of cervical syondylosis.

OBJECTIVE: To investigate the correlation of parameters of lordosis type cervical spine saggital plane in asymptomatic adults.

METHODS: Cervical anteroposterior and lateral DR images of 120 adult patients with asymptomatic lordosis type cervical spine were retrospectively analyzed. The subjects were divided into three groups according to age: group A (21-40 years), group B (41-60 years), and group C (61-80 years). The sagittal parameters of the cervical spine were measured, including C₂-C₇ sagittal vertical axis (C₂-C₇SVA), central of gravity to C₇ sagittal vertical axis (CG-C₇ SVA), T₁ slope, C₀-C₂ Cobb angle and C₂-C₇ Cobb angle. The correlation between different imaging parameters and age was analyzed. This study was approved by the Ethics Committee, First Hospital of Shijiazhuang and Second Hospital of Hebei Medical University. All subjects signed the informed consent.

RESULTS AND CONCLUSION: (1) C₂-C₇ SVA (F=11.188, P < 0.001), CG-C₇ SVA (F=6.132, P=0.003) and T₁ slope (F=11.682, P < 0.001) were significantly different among different groups. There was no significant difference in C₀-C₂ Cobb angle (F=1.178, P=0.311) and C₂-C₇ Cobb angle (F=0.860, P=0.426). (2) T₁ slope was (51.63±5.85)°, (54.66±5.58)° and (57.48±4.74)° in groups A, B and C, respectively. Linear correlation analysis showed that T₁ slope was positively correlated with age (r=0.533, P < 0.001). T1 slope was positively correlated with C₂-C₇ Cobb angle (r=0.561, P < 0.001). These results indicated that T₁ slope increased with age in asymptomatic cervical lordosis adults. Moreover, T₁slope was positively correlated with age.
