Unilateral Biportal Endoscopic Posterior Cervical Foraminotomy

Abstract

Study Design: Retrospective control study. Objective: To compare the curative effects of unilateral biportal endoscopic posterior cervical foraminotomy (UBE-PCF) with full-endoscopic posterior cervical foraminotomy (FPCF). Summary of Background Data: There are few studies directly comparing outcomes between UBE-PCF and FPCF. The objective of this study was to compare outcomes between UBE-PCF and FPCF. Methods: A retrospective control study was conducted for 69 patients of cervical radiculopathy from July 2019 to December 2021. Clinical outcomes scores, including neck disability index, visual analog scale (VAS)-arm, and VAS-neck were evaluated. Serum creatine kinase levels and the size of the operating hole were measured. Results: Postoperative neck disability index, VAS-neck, and VAS-arm scores showed statistically significant improvement over preoperative scores (P<0.01). The operating time was significantly shorter in the UBE-PCF group (P<0.001). No significant differences were found in serum creatine kinase levels between the 2 groups (P>0.05). The mean area of the operating hole was 1.47+0.05 cm2 in the FPCF group and 1.79+0.11 cm2 in the UBE-PCF group. The difference was statistically significant (P<0.001). Conclusions: Both UBE-PCF and FPCF are safe and effective procedures for cervical radiculopathy. Predictable and sufficient decompression could be achieved by UBE-PCF in a shorter operation time. Level of Evidence: Treatment Benefits Level III.
