AB  - Background Cervical radiculopathy is a spine ailment frequently requiring surgical decompression via anterior cervical discectomy and fusion (ACDF) or posterior foraminotomy/discectomy. While endoscopic posterior foraminotomy/discectomy is gaining popularity, its financial impact remains understudied despite equivalent randomized long-term outcomes to ACDF. In a cohort of patients undergoing ACDF vs endoscopic posterior cervical foraminotomy/discectomy, we sought to compare the total cost of the surgical episode while confirming an equivalent safety profile and perioperative outcomes.Methods A single-center retrospective cohort study of patients with unilateral cervical radiculopathy undergoing ACDF or endoscopic cervical foraminotomy between 2018 and 2023 was undertaken. Primary outcomes included the total cost of care for the initial surgical episode (not charges or reimbursement). Perioperative variables and neurological recovery were recorded. Multivariable analysis tested age, body mass index, race, gender, insurance type, operative time, and length of stay.Results A total of 38 ACDF and 17 endoscopic foraminotomy/discectomy operations were performed. All patients underwent single-level surgery except for 2 two-level endoscopic decompressions. No differences were found in baseline characteristics and symptom length except for younger age (46.8 ± 9.4 vs 57.6 ± 10.3, P = 0.002) and more smokers (18.4% vs 11.8%, P = 0.043) in the ACDF group. Actual hospital costs for the episode of surgical care were markedly higher in the ACDF cohort (mean ±95% CI; $27,782 ± $2011 vs $10,103 ± $720, P < 0.001) driven by the ACDF approach (β = $17,723, P < 0.001) on multivariable analysis. On sensitivity analysis, ACDF was never cost-efficient compared with endoscopic foraminotomy, and endoscopic failure rates of 64% were required for break-even cost. ACDF was associated with significantly longer operative time (167.7 ± 22.0 vs 142.7 ± 27.4 minutes, P < 0.001) and length of stay (1.1 ± 0.5 vs 0.1 ± 0.2 days, P < 0.001). No significant difference was found regarding 90-day neurological improvement, readmission, reoperation, or complications.Conclusion Compared with patients treated with a single-level ACDF for unilateral cervical radiculopathy, endoscopic posterior cervical foraminotomy/discectomy can achieve a similar safety profile, pain relief, and neurological recovery at considerably less cost. These findings may help patients and surgeons revisit offering the posterior cervical foraminotomy/discectomy utilizing endoscopic techniques.Clinical Relevance Endoscopic posterior cervical foraminotomy/discectomy offers comparable safety, pain relief, and neurological recovery to traditional methods but at a significantly lower cost.Level of Evidence 3.
