Abstract: ObjectiveTo assess the efficacy and results of cervical double door laminoplasty for the treatment of cervical spinal cord injury without radiographic spinal fracture and dislocation.Methods24 patients (all men) with cervical spinal cord injury without radiographic spinal fracture and dislocation were treated with operation of cervical double door laminoplasty. The follow up period ranged from 3 months to 21 months. ASIA scores of motion and sensation before and after operation were compared.Results After surgical treatment, ASIA scores of motion and sensation of patients were improved from 35.2±7.1 and 72.4±13.1 to 59.3±6.8 and 122.2±15.2 respectively and having a significant difference compared with that before operation (P<0.01).Conclusion Cervical double door laminoplasty, which is characterized by thorough decompression of spinal cord and preserving the posterior supporting tissue as much as possible to maintain the stabilization of cervical spine after operation, is an ideal optional method for cervical spinal cord injury without radiographic spinal fracture and dislocation.
