[Multivariate analysis of the operative effect on cervical spinal cord injury without fracture or dislocation]
1Department of Orthopaedics, the Affiliated Hospital of North Sichuan Medical College, Nanchong 637000, Sichuan, China.
Objective:
To explore the influencing factors of the operative effect on cervical spinal cord injury without fracture or dislocation.
Methods:
The clinical data of 69 patients with cervical spinal cord injury without fracture or dislocation from November 2010 to November 2016 who received operation were retrospectively analyzed. There were 37 males and 32 females, aged from 32 to76 years with an average of (51.6±7.3) years. The clinical data of 12 factors were selected, including age, gender, ASIA grade of spine cord injury, the length of spine cord injury by MRI, Pavlov ratio, ossification of the posterior longitudinal ligament (OPLL), intervertebral disc herniation, type of spine cord injury by MRI, time from injury to operation, treatment of high-dose methylprednisolone, operation time, intraoperative bleeding volume. In order to screen the main influencing factors of above items to prognosis, the single factor and multiple factor Logistic regression analysis were used in the clinical data by SPSS 22.0 statistical software.
Results:
Univariate analysis results showed that the factors including ASIA grade of spine cord injury, the length of spine cord injury by MRI, Pavlov ratio, ossification of longitudinal ligament, intervertebral disc herniation, the type of spine cord injury by MRI were associated with prognosis (P<0.05). Multi factor analysis of the selected factors indicated that the type of spine cord injury by MRI, the length of spine cord injury by MRI, Pavlov ratio, ASIA grade of spine cord injury were the main prognostic factors according to the influence intensity (P<0.05).
Conclusion:
The influencing factors of the operative effect on cervical spinal cord injury without fracture and dislocation were the type of spine cord injury by MRI, the length of spine cord injury by MRI, Pavlov ratio, ASIA grade of spine cord injury, and the foremost were the type and length of spine cord injury by MRI. Compared with other patients, preoperative MRI showed the patient with spinal cord injury type with bleeding and edema, or the length of spine cord injury larger than 45 mm may be less effective, therefore, it is necessary to thoroughly communicate with the patients and their kin before surgery.
