OBJECTIVE: The aim of this study was to observe the clinical efficacy and safety of minimally invasive posterior cervical foraminotomy (MI-PCF) and anterior cervical discectomy and fusion (ACDF) in the treatment of single-level unilateral cervical radiculopathy (SLUCR).

PATIENTS AND METHODS: We retrospectively analyzed 81 patients with SLUCR in two hospitals from February 2020 to February 2022, including the MI-PCF group (n=40) and the ACDF group (n=41). The differences in neck and shoulder pain, visual analog score (VAS), upper limb radiating pain (VAS), and neck disability index (NDI) were compared. Operative time, intraoperative bleeding, hospital stay, and complications were also compared between the two groups.

RESULTS: The degree of neck and shoulder pain relief at 1 day postoperatively was better in the ACDF group than in the MI-PCF group (p<0.05), while there were no significant differences between the two groups in terms of neck and shoulder pain relief at 1 month, 3 months, 6 months, and 12 months postoperatively, (p>0.05). There were no significant differences in the relief of upper limb radiating pain and the decrease of NDI scores between the two groups at 1 day, 1 month, 3 months, 6 months, and 12 months after surgery (p>0.05). The patients in MI-PCF group had shorter operative time, less bleeding, and shorter hospital stay, which were statistically different (p<0.05). There was no statistical difference in the complication rate between the two groups, (p>0.05).

CONCLUSIONS: The clinical efficacy and safety of MI-PCF and ACDF in the treatment of SLUCR are satisfactory, meanwhile, MI-PCF has shorter operative time, less bleeding and shorter hospital stay than ACDF, which is worthy of clinical promotion.
