Is cervical total disc replacement able to achieve a lordotic alignment?

Abstract

Introduction: A retrospective review was performed to evaluate clinical symptoms and the alignment of cervical spine for patients who underwent a cervical total disc replacement (C-TDR).

Methods: 10 patients underwent a single-level C-TDR. Their JOA score, EQ5D, EQ-VAS, range of motion (ROM), segmental lordosis, and C2-C7 angle were evaluated at preoperation and at 6 months postoperation.

Results: JOA score, EQ5D, and EQ-VAS, ROM, and segmental lordosis were significantly improved at 6 months compared with the preoperative state though C2-C7 angle did not change significantly.

Conclusions: C-TDR increases the local lordosis but does not affect the global lordosis of the cervical spine at 6 months postoperation.
