BackgroundAnterior cervical discectomy and fusion (ACDF) is the gold standard treatment for this cervical radiculopathy. Posterior endoscopic cervical foraminotomy (PECF), an effective alternative to ACDF, is becoming widely used by an increasing number of surgeons. However, comparisons of the clinical outcomes of ACDF and PECF remain poorly explored. The purpose of this study was to evaluate and compare visual analog scale (VAS)-arm scores, VAS-neck scores, neck disability index (NDI) scores, reoperation, and complications in PECF and ACDF.Materials And MethodsWe comprehensively searched electronic databases or platforms, including PubMed, Web of Science, EMBASE, and the Cochrane Controlled Trial Center, using the PRISMA guidelines. The required information, including VAS-arm scores, VAS-neck scores, NDI scores, reoperation, and complications, was extracted from qualified studies and independently tested and compared by 2 researchers. The methodological index for nonrandomized studies was used to evaluate study quality.ResultsNine studies consisting of 230 males and 256 females were included. The mean age of the included patients was 49.6 years, and the mean follow-up time was 20.6 months. The VAS-arm scores were significantly higher, and VAS-neck scores and NDI scores of PECF showed greater improvement trends for PECF than ACDF. The complication proportion of patients with PECF was lower, while the proportion of reoperation was similar between PECF and ACDF. ACDF was the most common revision surgery. The most common complication of PECF was transient paresthesia.ConclusionCompared with ACDF, PECF is safe and effective in patients with unilateral cervical radiculopathy without myelopathy, and PECF does not increase the probability of reoperation and complications.
