Abstract:
Objective:To explore the use of anterior cervical corpectomy and fusion (ACCF) combined with anterior cervical discectomy and fusion (ACDF) in patients with multilevel cervical spondylopathy myelopathy (CSM).Methods:The clinical data of 83 patients with multi-segment CSM admitted to the Department of Spinal Surgery of Hubei Liuqi2 Orthopaedic Hospital of Integrated Traditional Chinese and Western Medicine from January 2018 to January 2021 were retrospectively analyzed. According to the different surgical methods used in their treatment, they were divided into group A and group B. In group A, 44 patients were treated with anterior cervical ACCF combined with ACDF, and 39 patients in group B were treated with posterior single-door laminoplasty. The general clinical indexes such as operation time, perioperative bleeding volume and hospitalization time were collected.The neurological function and cervical dysfunction improvement effect of the patients before and 6 months after operation were evaluated by using the Japanese Orthopaedic Association (JOA) score and neck disability index (NDI) scale. The cervical curvature of the patients before and 6 months after operation was compared, The complications of the two groups were observed 6 months after operation. The patients were divided into improved group (72 cases) and non improved group (11 cases). Comparison between count data groups χ 2 inspection. Independent sample t-test was used for comparison between measurement data groups conforming to normal distribution. According to the results of univariate analysis, the meaningful factors were included in the binary Logistic regression to analyze the influencing factors related to the surgical efficacy. Result:The perioperative blood loss ((153.36±10.68) mL) and hospital stay ((10.11±2.30) d) in group A were lower than those in group B ((171.47±11.32) mL, (15.58±3.76) d). There were significant differences between the two groups ( t values were 7.50 and 8.10; both P<0.001). Six months after operation, the JOA score (13.70±1.49, 12.94±1.63) and cervical curvature (22.10±3.23, 13.38±3.12) of patients in groups A and B were all higher than those before operation (9.40±1.32, 9.36±1.51; 11.16±2.60, 11.23±2.71), and group A was higher than group B, the difference was statistically significant (JOA scores before and after operation: t values were 14.33 and 10.07, respectively; cervical curvature: t values were 17.50 and 3.25, respectively; t values between groups were 2.22 and 12.47, respectively, and the P values were <0.001, <0.001, <0.001, 0.002, 0.029 and <0.001, respectively). Six months after the operation, the NDI indexes of groups A and B (11.38±4.76, 14.79±4.85) were lower than those before the operation (39.56±9.43, 39.74±9.51), and those in group A were lower than in group B, and the difference was statistically significant ( t values were 17.70, 14.60, and 3.23; all P<0.001). Binary Logistic regression showed that the duration of disease ≥6 months ( OR=59.045, 95% CI: 6.485-537.629), the presence of cervical spinal cord MRI signal changes ( OR=0.031, 95% CI: 0.002-0.587), the surgical approach (posterior approach single-door laminoplasty) ( OR=6.300, 95% CI: 1.269-31.273) was an independent risk factor affecting the surgical outcome ( P values were <0.001, 0.021, and 0.024, respectively). Conclusion:Anterior cervical ACCF combined with ACDF has an ideal surgical effect in the treatment of patients with multi-segment CSM, which can significantly improve the cervical spinal nerve function and cervical curvature, shorten the operation time and reduce the perioperative blood loss. It isstill necessary to pay attention to the patient's disease course, MRI signals changes of cervical spinal cord and the effect of surgical methods on their surgical outcomes.
