Area of Science:

  • Radiology
  • Neurosurgery
  • Orthopedic Surgery

Background:

  • Failed back surgery syndrome (FBSS) is characterized by persistent or recurrent pain following spinal surgery.
  • It encompasses diverse etiologies, including mechanical and non-mechanical causes.
  • Postoperative imaging is critical for evaluating complications contributing to FBSS.

Purpose of the Study:

  • To provide radiologists with a comprehensive understanding of normal postoperative imaging findings.
  • To aid in the identification of pathological imaging features indicative of FBSS.
  • To enhance diagnostic accuracy in the postoperative spinal surgery setting.

Main Methods:

  • Review of imaging techniques used in the postoperative follow-up of spinal surgery.
  • Analysis of normal postoperative changes associated with spinal fusion and decompressive procedures.
  • Identification of specific imaging findings related to FBSS complications.

Main Results:

  • Normal postoperative changes vary based on surgical technique (fusion vs. decompression) and time elapsed.
  • Key findings for fusion surgery include assessing bone fusion, hardware integrity, and adjacent bone/segmental changes.
  • Distinguishing expected decompressive changes from peridural fibrosis, recurrent herniation, and infections is crucial.

Conclusions:

  • Accurate interpretation of postoperative spinal imaging requires knowledge of surgical procedures and timelines.
  • Radiologists must be adept at recognizing both normal healing and pathological complications of spinal surgery.
  • This review serves as a guide for identifying imaging findings associated with failed back surgery syndrome.
