Abstract/OtherAbstract:
Study Design: Prospective studyObjective: To analysis the effect of T1 slope on kyphotic alignment change after cervical laminoplasty in cervical myelopathy patientsSummary of Background Data: Laminoplasty is a posterior method, and maintenance of both preoperative and postoperative lordotic alignment is prerequisite for the successful surgery. However, unfortunately, patients who underwent laminoplasty tends to have kyphotic alignment change after operation despite preoperative enough lordosis, and such kyphotic alignment change after cervical laminoplasty can reduce surgical outcome and require additional surgery.Methods: Consecutive patients who underwent cervical laminoplasty for cervical myelopathy were enrolled. Cervical spine lateral radiography in neutral, flexion, and extension were taken before surgery and at 2-year follow-up. Patients were divided into two groups according to the preoperative T1 slope, and postoperative cervical alignment change was compared according to the preoperative T1 slope.Results: Total 51 patients were enrolled in this study. The mean age was 57.2 years (range, 39 to 88 years). There were 39 male patients and 12 female patients. There were no differences in age, sex, the presence and type of OPLL, and operation level between the patients with higher and lower preoperative T1 slope. Patients with higher preoperative T1 slope had more lordotic preoperative cervical alignment, however, they had more kyphotic alignment changes after laminoplasty (p<0.001). After univariate logistic regression, only higher preoperative T1 slope was associated with significantly increased odd ratio for postoperative kyphotic alignment changes.Conclusion: We hypothesized that kyphotic alignment change by posterior structural injury after cervical laminoplasty would be more marked in patients with high T1 slope, and demonstrated that cervical myelopathy patients with high T1 slope had more kyphotic alignment changes after cervical laminoplasty at 2-year follow-up.
