Preoperative cervical alignment parameters can predict postoperative disability scores and myelopathy outcomes

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Spinal Deformity

Background:

• Cervical myelopathy significantly impacts patient quality of life.
• Anterior cervical corpectomy and fusion (ACCF) is a common surgical treatment.
• Understanding factors influencing surgical outcomes is crucial.

Purpose of the Study:

• To investigate the relationship between preoperative cervical spine alignment and postoperative myelopathy.
• To assess the predictive value of specific alignment parameters on surgical outcomes.
• To correlate radiological findings with clinical assessments post-ACCF.

Main Methods:

• Retrospective analysis of patients undergoing ACCF for cervical myelopathy.
• Evaluation of preoperative cervical alignment: T1 sagittal angle, T1 slope, C2-7 sagittal vertical axis (SVA).
• Assessment of postoperative outcomes using mJOA, NDI, and VAS scores; statistical analysis via correlation and regression.

Main Results:

• No significant demographic differences between single-level and multilevel corpectomy groups.
• Significant differences noted in postoperative C2-7 Cobb angle, operative time, and blood loss.
• Higher C2-7 SVA correlated with worse operative outcomes.

Conclusions:

• Preoperative T1 slope and C2-7 SVA are potential predictors of myelopathy outcomes post-ACCF.
• Accurate prediction of clinical outcomes is vital for optimizing postoperative management.
• Cervical alignment parameters offer valuable insights for surgical planning and patient care.
