Abstract
BACKGROUND: Currently, the scientific data lack well-substantiated clinical and radiologic indications for the differentiated use of anterior cervical discectomy with two-level interbody fusion versus anterior cervical corpectomy with single-level transbody fusion in patients with two-level degenerative cervical spine disease.
AIM: This work aimed to prospectively assess the long-term clinical outcomes of an algorithmic approach for the selection of anterior interbody cervical fusion versus anterior transbody cervical fusion in patients with two-level degenerative cervical spine disease.
METHODS: The treatment of patients with two-segment degenerative cervical spine disease was compared between a prospective cohort (n = 97), operated according to a preoperative clinico-morphologic algorithm in neurosurgical departments in Irkutsk and Krasnoyarsk during 2021–2023, and a retrospective control group (n = 186), operated at the Irkutsk Neurosurgery Center in 2009–2020 using the same surgical techniques according to surgeon preference.
RESULTS: After undergoing anterior interbody cervical fusion, the prospective group demonstrated significantly better trends in improvement as compared with the retrospective group, including neurologic function recovery (p < 0.05), regression of pseudoradicular symptoms (p < 0.05), improvement in cervical disability scale indices (p = 0.03) and modified Japanese Orthopaedic Association scores (p = 0.04), improvement in both physical (p = 0.01) and psychological (p = 0.01) SF-36 health components, and better MacNab scale outcomes (p = 0.006). After anterior transbody cervical fusion, the prospective group demonstrated significantly better trends in improvement than the retrospective group did, including neurologic function recovery (p < 0.05), regression of pseudoradicular symptoms (p < 0.05), improvement in cervical disability scale indices (p = 0.03) and modified Japanese Orthopaedic Association scores (p = 0.01), as well as better physical (p = 0.02) and psychological (p = 0.01) health components of the SF-36. Complication rates in the prospective subgroups were significantly lower than those in the retrospective subgroups.
CONCLUSION: In two-level degenerative cervical spine disease, an algorithm-based anterior approach to the differentiated selection of anterior interbody versus anterior transbody cervical fusion led to a significant improvement in clinical outcomes and a reduction in postoperative complications at a minimum 2-year postoperative follow-up.
