Abstract
Purpose: The purpose of this study is to compare and analyze the clinical results according to the complications occurring after laminoplasty for cervical myelopathy patients. Materials and Methods: Among patients diagnosed as cervical myelopathy, 152 cases in which patients underwent cervical laminoplasty from March 2006 to March 2011 from Chungnam National University Hospital and had follow-up for at least two years were selected for the study, and the mean follow-up period was 39.7 months. The cases were divided into two groups; cases that underwent plate fixation for hinge fracture during cervical laminoplasty or showed postoperative spontaneous interlamina fusion were included in group A and cases that did not show such complications were included in group B. Clinical results were measured using visual analogue scale (VAS) score and Neck Disability Index (NDI) preoperatively, postoperatively, and on the final follow-up. Results: Among 152 cases, 31 cases were included in group A and 121 cases in group B. Group A consisted of 11 cases of fixation due to intraoperative hinge fracture and 20 cases of postoperative spontaneous interlamina fusion. Mean preoperative VAS score was 7.52 in group A and 7.26 in group B, and mean postoperative VAS score was 2.87 in group A and 3.03 in group B. Mean NDI improved from 74.32% preoperatively to 43.84% postoperatively in group A and 75.74% preoperatively to 45.36% postoperatively in group B. In both groups, on postoperative follow-up, no significant difference of VAS score and NDI was found and both showed improvement compared to before surgery. Conclusion: The clinical results of cases that underwent plate fixation for hinge fracture that occurred during cervical laminoplasty and postoperative spontaneous interlamina fusion showed no significant difference compared to cases that did not show any complications.
