Area of Science:

  • Spine surgery
  • Surgical complications
  • Patient outcomes

Background:

  • Complication rates in adult spinal deformity (ASD) surgery lack standardized categorization.
  • This variability hinders accurate assessment of surgical outcomes.
  • A robust classification system is needed to evaluate complication impact.

Purpose of the Study:

  • To assess the impact of complication occurrence, severity (minor-major), and Clavien-Dindo classification (Cc) on clinical variables and patient-reported outcomes in ASD surgery.
  • To identify the most effective system for categorizing complications in ASD surgery.

Main Methods:

  • Retrospective review of a prospective database of adult spinal deformity patients.
  • Analysis of intraoperative, perioperative, and postoperative complications.
  • Evaluation of complication presence, minor-major status, and Cc score against surgical outcomes (EBL, LOS, reoperation) and HRQL scores at 2 years.

Main Results:

  • Over half of ASD patients experienced postoperative complications (58.7%).
  • Major intraoperative complications correlated with increased EBL and LOS.
  • Postoperative complications and higher perioperative Cc scores predicted worse 2-year HRQL outcomes.

Conclusions:

  • The Clavien-Dindo classification (Cc) is highly effective in predicting patient outcomes after ASD surgery.
  • Higher perioperative Cc scores and postoperative complications are linked to reduced long-term health-related quality of life improvement.
  • Complications significantly impact both short-term surgical results and long-term patient recovery.
