Insights

Hyperlipidemia (HLD) impacts posterior cervical spine fusion (PCF) outcomes. While HLD increased cervicalgia in multilevel PCF, it decreased other complications like respiratory failure and spinal cord injury.

Area of Science:

  • Spine Surgery
  • Cervical Spine Fusion
  • Hyperlipidemia Research

Background:

  • Hyperlipidemia (HLD) is a prevalent condition linked to atherosclerosis and associated diseases.
  • The impact of HLD on outcomes following posterior cervical spine fusion (PCF) remains under-investigated.
  • Understanding HLD's role is crucial for managing patients undergoing spinal procedures.

Purpose of the Study:

  • To evaluate the effect of hyperlipidemia (HLD) on perioperative complications after posterior cervical spine fusion (PCF).
  • To compare complication rates between patients with and without HLD undergoing PCF.

Main Methods:

  • Retrospective database study using the MSpine subset of the PearlDiver Patient Record Database (2010-2020).
  • Analysis of perioperative complications using ICD-9, 10, and CPT codes.
  • Age-, sex-, and Charlson Comorbidity Index (CCI)-matched populations compared using chi-squared analysis.

Main Results:

  • Propensity score matching analyzed 1600 patients (single-level PCF) and 6855 patients (multilevel PCF).
  • HLD decreased respiratory failure in single-level PCF (OR=0.58).
  • In multilevel PCF, HLD increased cervicalgia (OR=1.26) but decreased spinal cord injury, dysphagia, respiratory failure, pneumonia, neurological bladder, and urinary tract infection incidence.

Conclusions:

  • Hyperlipidemia (HLD) is associated with an increased incidence of postoperative cervicalgia in multilevel PCF.
  • Conversely, HLD was linked to a significant decrease in several other perioperative complications.
  • Further research is warranted to explore HLD treatment efficacy and intraoperative factors.
