Extraforaminal disk herniation, a rare condition, presents unique symptoms and is best diagnosed with CT scans. Surgical outcomes are generally good, with CT enabling more conservative treatment approaches.

Area of Science:

  • Neurosurgery
  • Radiology
  • Orthopedics

Background:

  • Extraforaminal disk herniation, located lateral to the intervertebral foramen, has distinct clinical and neurological features compared to other types.
  • Pre-CT imaging, diskography was the primary method for diagnosing this rare condition.

Purpose of the Study:

  • To present five cases of extraforaminal disk herniation diagnosed and confirmed surgically.
  • To highlight the diagnostic utility of CT scans in identifying extraforaminal disk herniations.
  • To discuss the surgical management and outcomes of these cases.

Main Methods:

  • Case series of five patients with surgically confirmed extraforaminal disk herniation.
  • Diagnosis based on clinical presentation and CT scans.

  • Surgical intervention included hemilaminectomy, facetectomy, and diskectomy.

    • Main Results:

    • All patients experienced severe motor deficits and predominantly sciatica.
    • CT scans accurately identified disk protrusion, extrusion, and sequestration in most cases.
    • Post-operative follow-up showed excellent or good clinical results in all patients after an average of 10 months.

    Conclusions:

    • CT scans have significantly improved the diagnosis of extraforaminal disk herniation, reducing the need for invasive procedures.
    • Early tomographic localization allows for more conservative surgical techniques.
    • Clinical examination remains crucial for accurate CT interpretation and treatment planning.
