The Effects of Posterior Surgical Approach on Cervical Alignment in The Treatment of Cervical Spondylotic Myelopathy

Objective: To investigage the effect of surgical approaches used in the treatment of degenerative cervical spondylotic myelopathy on cervical alingment and vertebral canal diameter measurements

Material and Methods: 45 patients were operated with degenerative cervical sponylotic myelopathy (CSM) in our clinic between 2016 and 2020. 23 of them including 5 females and 18 males, were operated  with open door laminoplasty; and 22 of them including 4 females and 18 males, were operated with  laminectomy with  lateral mass screw fusion. SVA (Distance between C2 midline and C7 superior end plate midline), Cobb angles (The angle between the lines passing through C2 lower end plate and C7 lower end plate), and VCD (vertebral canal diameter measured from MR images) values of patients ​​were measured.

Results: Collected data of patients in preoperative period and 1 year after operation were evaluated statistically.

Conclusion: Plate and screw systems not causing facet joint damage use in patients with CSM are more effecticve in the cervical alignment protection
