Summary
Cervical disc arthroplasty with the Prestige-LP device preserved cervical alignment and restored segmental lordosis. Restored C5-C6 lordosis correlated with reduced arm pain, suggesting its importance for clinical outcomes.
Area of Science:
- Spine surgery
- Orthopedic biomechanics
- Cervical spine research
Background:
- Cervical disc arthroplasty aims to maintain or restore spinal alignment and motion.
- The Prestige-LP disc is used for cervical disc replacement.
- Understanding the impact on cervical alignment and clinical outcomes is crucial.
Purpose of the Study:
- To evaluate the effect of Prestige-LP disc implantation at C5-C6 on cervical alignment.
- To investigate the association between cervical alignment and clinical outcomes post-surgery.
Main Methods:
- Retrospective review of 77 patients undergoing C5-C6 cervical disc arthroplasty.
- Assessment of clinical outcomes using Japanese Orthopaedic Association score, neck disability index, and VAS for pain.
- Measurement of cervical range of motion (ROM) and alignment (C2-C7 angle, C5-C6 angle).
Main Results:
- Significant improvements in VAS and neck disability index, and increase in JOA scores observed.
- Cervical alignment (C2-C7 angle) was preserved; C5-C6 angle significantly restored lordosis.
- A significant correlation found between C5-C6 angle restoration and reduced arm pain (VAS).
Conclusions:
- Cervical disc arthroplasty with Prestige-LP effectively restored C5-C6 segmental lordosis.
- Restored segmental lordosis is associated with improved clinical outcomes, specifically reduced arm pain.
