Incidence and Outcomes of C5 Palsy and Axial Pain After Open-Door Laminoplasty or Laminectomy and Fusion: A Meta-Analysis.

C5 palsy and axial pain are significant factors affecting the quality of life after posterior cervical surgery; however, there has been no clear and supportive conclusion on which method is more suitable in a certain case. As a result, we compare the clinical outcomes, complication rates, and anatomical changes between open-door laminoplasty (ODL) and laminectomy and fusion (LF) for cervical spondylotic myelopathy. This is a systematic literature review and meta-analysis. A comprehensive literature search was conducted using PubMed, Embase, and the Cochrane library. The following outcomes were extracted and analyzed: the cases of C5 palsy and axial pain patients, Japanese Orthopaedic Association, range of motion (ROM), and cervical curvature. Data analysis was conducted with RevMan 5.3. The I A total of 9 studies were included in the final analysis, all of which were prospective or retrospective cohort studies. The pooled data showed that the incidences of C5 palsy and axial pain in LF were higher than those in ODL. The study indicated that there was no significant difference in pre- and postoperative Japanese Orthopaedic Association scores, preoperative cervical ROM, pre- and postoperative cervical curvature between the 2 groups, but there was significant difference in ROM after operation. These results indicate that ODL was superior to LF in maintaining cervical ROM. Our results demonstrate that the lower incidence of C5 palsy and axial pain can be achieved by using ODL compared with LF. However, current data only provide weak support, if any, favoring ODL over for clinical improvement in reduce these 2 complications.
