Clinical and Radiological Comparison of Hybrid Surgery and Fusion Application with Peek Cage in Patients Undergoing Three-Level Anterior Cervical Discectomy.

Objective: In this study, we aimed to compare patients with degenerative cervical disc herniation (CDH) who had undergone three-level anterior cervical discectomy (ACD) and fusion with a peek cage supported by synthetic bone graft in all levels to the cases with CDH with hybrid surgery (HS) regarding their radiological findings and surgical results. Materials and Methods: The patients who had undergone three-level ACD were evaluated retrospectively. The cases who were followed up for 2 years and longer were evaluated regarding gender, age, radiological findings, and patient satisfaction. A radiological assessment was made by calculating the Cobb angle on lateral cervical radiographs. Clinical assessment was performed by the Neck Disability Index (NDI). Results: In the first group, 13 patients had undergone ACD and fusion with peek cage and bone graft, and in the hybrid group, there were 11 patients in whom fusion with peek cage and bone graft were made in two levels, and cervical disc arthroplasty was performed throughout the distance in-between. In the hybrid group, the 1-month and 24-month changes in cervical range of motion in hyperflexion were statistically significant ( Conclusions: HS is a reliable and effective treatment method in the three-level cervical disk disease for preserving and improving cervical ROM, particularly in the flexion position.
