Purpose

The purpose of this research is to compare the clinical efficacy, postoperative complication and surgical trauma between anterior cervical corpectomy and fusion versus posterior laminoplasty for the treatment of oppressive myelopathy owing to cervical ossification of the posterior longitudinal ligament (OPLL).

Study design

Systematic review and meta-analysis.

Methods

An comprehensive search of literature was implemented in three electronic databases (Embase, Pubmed, and the Cochrane library). Randomized or non-randomized controlled studies published since January 1990 to July 2017 that compared anterior cervical corpectomy and fusion (ACCF) versus posterior laminoplasty (LAMP) for the treatment of cervical oppressive myelopathy owing to OPLL were acquired. Exclusion criteria were non-human studies, non-controlled studies, combined anterior and posterior operative approach, the other anterior or posterior approaches involving cervical discectomy and fusion and laminectomy with (or without) instrumented fusion, revision surgeries, and cervical myelopathy caused by cervical spondylotic myelopathy. The quality of the included articles was evaluated according to GRADE. The main outcome measures included: preoperative and postoperative Japanese Orthopedic Association (JOA) score; neuro-functional recovery rate; complication rate; reoperation rate; preoperative and postoperative C2–C7 Cobb angle; operation time and intraoperative blood loss; and subgroup analysis was performed according to the mean preoperative canal occupying ratio (Subgroup A:the mean preoperative canal occupying ratio

Results

A total of 10 studies containing 735 patients were included in this meta-analysis. And all of the selected studies were non-randomized controlled trials with relatively low quality as assessed by GRADE. The results revealed that there was no obvious statistical difference in preoperative JOA score between the ACCF and LAMP groups in both subgroups. Also, in subgroup A (the mean preoperative canal occupying ratio

Conclusion

In summary, when the preoperative canal occupying ratio
