Abstract

   Background: cervical myelopathy usually results from compression on cervical spinal cord, caused by unstable and degenerative spine, cervical disc herniation, ossification of posterior ligamentum flavum or spinal tumors. Posterior decompression with laminectomy,  lateral mass screws and articulating facet fusion is the first choice because it is easy to perform, low risk of complications and achieve the stability of cervical spinal structure. Objectives: to evaluate recovery rate of Japanese Orthopaedic Association score, healing rate of articulating facet fusion and complications. Materials and methods: a cross-sectional study included 59 consecutive patients (53 males, 6 females) that were treated for cervical myelopathy with C3-7 laminectomy, lateral mass screws and articulating facet fusion from 1/2018 to 12/2019. Results: median follow-up time was 17.51 ± 6.5 months. Data showed the recovery rate of Japanese Orthopaedic Association score was 65.07% (min 29%, max 88%). The healing rate of articulating facet fusion was 96.1%. There were no neurologic or vascular complications and postoperative instrumentation failures. Conclusion: posterior decompression with laminectomy, lateral mass screws and articulating facet fusion was a simple, safe and effective procedure that could be achieved stability for spine structure, bone healing and recovery of damaged spinal cord in cervical myelopathy.
