Key Points

The study aims to determine the relationship between pelvic incidence and proximal junctional failure after long-segment spinal fusion.
Analyzed data from patients undergoing long-segment spinal fusion.
Evaluated preoperative pelvic incidence morphology.
Assessed the occurrence of proximal junctional failure post-surgery.
Patients with lower pelvic incidence have a higher risk of proximal junctional failure.
Utilizing pelvic incidence can help preoperatively to reduce junctional pathologies.

Implication

This research demonstrates that pelvic incidence predicts proximal junctional failure in patients, suggesting improved surgical planning.

Abstract

Patients with lower PI are at an increased risk of PJF following long-segment fusion. Preoperative PI morphology may be used to inform surgical planning and reduce the risk of junctional pathologies.
