Abstract:
BACKGROUND:Bryan cervical disc replacement and anterior cervical discectomy and fusion have a dispute in the treatment of cervical spondylosis.
OBJECTIVE:To evaluate the clinical effects of Bryan cervical disc replacement and anterior cervical discectomy and fusion by meta-analysis, thereby providing clinical evidence for treatment strategy of cervical spondylosis.
METHODS:The authors searched Medline, PubMed, EMBASE, OVID, CBM, CNKI and also searched manual y seven relevant Chinese orthopedic journals for articles pertinent to clinical research of Bryan cervical disc replacement and anterior cervical discectomy and fusion. Extracted data included the range of motion of the cervical spine, visual analog scale score, neck disability index, the Japanese Orthopaedic Association score. Meta-analysis and forest plots were conducted with RevMan4.2.2 Software.
RESULTS AND CONCLUSION:There are eight articles in the meta-analysis, including 883 patients (430 patients receiving Bryan cervical disc replacement, and 453 patients receiving anterior cervical discectomy and fusion). Meta-analysis did detect statistical y significant differences in the range of motion of the cervical spine at 3 months and 24 months postoperatively between the two groups, but did not detect statistical y significant differences in visual analog scale score, neck disability index, the Japanese Orthopaedic Association score between the two groups. These findings indicate that Bryan cervical disc replacement is superior to anterior cervical discectomy and fusion in the range of motion of the cervical spine. However, the current literature offers no evidence to support superiority of the Bryan cervical disc replacement over the anterior cervical discectomy and fusion.
