Abstract:

BACKGROUND: Laminoplasty and laminectomy are the most commonly used treatment methods for multilevel cervical spondylotic myelopathy, which is more common in elderly patients. C5 nerve root palsy is the common postoprative complication after posterior cervical repair.
OBJECTIVE: To compare the incidence of C5 nerve root palsy after laminoplasty with mini-titanium plate fixation and laminectomy with internal fixation in repair of multilevel cervical spondylotic myelopathy.
METHODS: Totally 134 patients with multilevel cervical spondylotic myelopathy from August 2010 to December 2014 were enrolled, and then divided into laminoplasty group (n=45) and laminectomy group (n=89) owing to different ways of repair. Patients in the laminoplasty group were treated with laminoplasty with mini-titanium plate fixation, and patients in the laminectomy group were treated with laminectomy with internal fixation. C5 nerve root palsy condition after repair was recorded and evaluated. The cervical lordosis angle (Cobb angle) and cervical curvature index were compared. The Japanese Orthopaedic Association score was used for neurological assessment.
RESULTS AND CONCLUSION: All patients in both groups were followed up for more than 6 months. There were no significant differences in cervical lordotic angle and cervical curvature index at the first week before and after  the treatment between these two groups (P > 0.05). The Japanese Orthopaedic Association scores of patients after 6 months of treatment were significantly improved compared with that before treatment in these two groups (P < 0.05). There were 2 cases of C5 nerve root palsy after the treatment of laminoplasty, the occurrence rate was 4% (2/45); there were 10 cases of C5 nerve root palsy after the treatment of laminectomy, the occurrence rate was 11% (10/89); there was significant difference between these two groups (P < 0.05). These results suggest that compared with laminectomy fixation, the incidence of C5 nerve root palsy was lower after the laminoplasty with mini-trianium plate fixation, which can be widely used in decompression repair treatment of multilevel cervical spondylotic myelopathy.
