Anterior corpectomy versus posterior laminoplasty for the treatment of multilevel cervical myelopathy: A meta-analysis.
OBJECTIVE
To compare the effectiveness between anterior corpectomy (CORP) and posterior laminoplasty (LAMP) for the treatment of multilevel cervical myelopathy.


METHODS
Systematic review and meta-analysis.


METHODS
We searched MEDLINE, EMBASE, PubMed, OVID, Web of Science and the Cochrane Central Register of Controlled Trials databases for all relevant articles that compared the two operations for the treatment of multilevel cervical myelopathy. Exclusion criteria were non-controlled studies, combined anterior and posterior surgery, follow-up <1 year and patients with tumors, trauma, soft disc herniation or previous surgery. The following outcome measures were extracted: Japanese orthopedic association (JOA) score, neurological recovery rate, surgical complications, reoperation rate, operation time and blood loss.


RESULTS
7 high quality studies were included in the meta-analysis. There was no significant difference in preoperative JOA score [P > 0.05, WMD 0.31 (-0.16, 0.79)] and complication rate [P > 0.05, OR 1.26 (0.82,1.94)] between the two groups. Significant less reoperation rate [P < 0.05, OR 8.16 (3.10, 21.51)], operation time [P < 0.05, WMD 67.94 (50.69, 85.20)] and blood loss [P < 0.05, WMD 170.06 (80.05, 260.08)] were found in posterior LAMP group. Whereas, patients in anterior CORP group obtained a better postoperative JOA score [P < 0.05, WMD 2.02 (1.61, 2.43)] and neurological recovery rate [P < 0.05, WMD 7.22 (0.36,14.08)] than that in posterior LAMP group.


CONCLUSIONS
Anterior CORP has a higher postoperative JOA score and neurological recovery rate compared with posterior LAMP. However, significant higher reoperation rate, operation time and blood loss should be taken into consideration when anterior CORP is used. High-quality RCTs with long-term follow-up and large sample size are needed.
