Keywords: Anterior cervical discectomy and fusion, cervical disc arthroplasty, hybrid surgery, range of motion.


Objectives: The study aims to explore the management of two-level cervical disc disease and to compare outcomes of anterior cervical discectomy and fusion (ACDF), cervical disc arthroplasty (CDA), and hybrid surgery (HS).

Patients and methods: Between December 2011 and December 2021, a total of 120 patients (76 males, 44 females; mean age: 44.8±8.1 years; range, 18 to 68 years) who were diagnosed as two-level cervical disc disease and underwent anterior cervical surgery were retrospectively analyzed. The patients were randomly divided into three groups as ACDF, CDA, and HS each consisting of 40 patients. The Neck Disability Index (NDI), Visual Analog Scale (VAS), clinical and radiological findings, and range of motion (ROM) data were evaluated.

Results: All of the groups showed a significant improvement according to clinical and radiological outcomes (p=0.01). The mean follow-up was 27.5±6.1 months for ACDF, 20.0±4.7 months for CDA, and 21.1±5.0 months for HS, showing consistency in monitoring post-surgery outcomes. The mean postoperative NDI scores were 13.4±5.6, 14.8±5.2 and 15.0±5.5 in the ACDF, CDA and HS groups, respectively (p=0.056). The mean postoperative ROM values were 20.82±5.66, 32.45±11.21 and 27.18±10.89, respectively (p=0.045).

Conclusion: All three surgical techniques, ACDF, CDA, and HS, are safe and successful in the treatment of two-level cervical disc disease. However, HS and CDA may be more preferable over ACDF attributed to their motion-preserving benefits and effectively combining fusion and motion preservation techniques, with comparable clinical and radiological outcomes.
