    The intravertebral vacuum phenomenon, a sign of non-healing vertebral fracture, was observed in 17 patients. This finding can occur alongside multiple myeloma and does not rule out malignancy.

    Area of Science:

    • Orthopedics
    • Radiology
    • Pathology

    Background:

    • The intravertebral vacuum phenomenon (IVP) is a rare finding within vertebrae.
    • It is often associated with non-healing vertebral fractures and can mimic other spinal pathologies.

    Purpose of the Study:

    • To describe the occurrence and potential causes of the intravertebral vacuum phenomenon.
    • To evaluate its association with malignancy and diagnostic imaging considerations.

    Main Methods:

    • Retrospective analysis of 17 patients with 19 affected vertebrae exhibiting the intravertebral vacuum phenomenon.
    • Review of medical histories and imaging findings, including radiographs taken during traction or extension.

    Main Results:

    • The intravertebral vacuum phenomenon was observed in 19 vertebrae across 17 patients.

  • Potential etiologies discussed include ischemic bone necrosis, trauma-induced necrosis, and intraosseous disc prolapse.
  • The phenomenon was present in two patients with multiple myeloma, indicating it does not exclude malignancy.

    • Conclusions:

    • The intravertebral vacuum phenomenon represents a non-healing vertebral fracture with several potential underlying mechanisms.
    • Its presence does not rule out underlying malignancy, such as multiple myeloma.
    • Radiographic imaging during spinal traction or extension may aid in diagnosis.
