Summary

This summary is machine-generated.

Loss of cervical lordosis (LOCL) is a common post-surgery deformity. Preoperative T1s angle > 24.5° and postoperative CL angle < 9.5° predict LOCL development after cervical spinal tumor surgery.

Area Of Science

  • Neurosurgery
  • Orthopedics
  • Spinal Surgery

Background

  • Loss of cervical lordosis (LOCL) is a frequent complication following cervical spine surgery.
  • Identifying predictors of LOCL is crucial for improving patient outcomes after cervical spinal cord tumor resection.

Purpose Of The Study

  • To determine the predictors of LOCL after surgical resection of cervical spinal cord tumors.
  • To analyze the association between preoperative and postoperative cervical sagittal alignment and LOCL development.

Main Methods

  • Retrospective analysis of 51 patients undergoing cervical spinal tumor resection.
  • Collection and analysis of pre- and postoperative cervical sagittal alignment parameters.
  • Multiple logistic regression and ROC curve analysis to identify significant predictors.

Main Results

  • Postoperative Cervical Lordosis (Post-CL) angle < 9.5° (p=0.009) and preoperative T1 slope (Pre-T1s) angle > 24.5° (p=0.005) were significant predictors of LOCL.
  • ROC analysis confirmed significant associations: Post-CL (p=0.008, AUC=0.718) and Pre-T1s (p=0.025, AUC=0.687).
  • Tumor characteristics and patient demographics did not significantly predict LOCL.

Conclusions

  • Postoperative cervical alignment and preoperative T1 slope are key predictors of LOCL after cervical spinal tumor surgery.
  • Patients with specific alignment parameters (Post-CL < 9.5° or Pre-T1s > 24.5°) face a higher risk of LOCL.
  • Consideration of active intervention and surgical follow-up is recommended for high-risk patients.
