Spinal vacuum phenomena: anatomical study and review

Area of Science:

• Spinal Imaging and Diagnostics
• Radiology
• Orthopedic Pathology

Background:

• Vacuum phenomena involve gas accumulation (primarily nitrogen) within spinal structures.
• These phenomena can occur in various spinal conditions, not exclusively degenerative disc disease.

Purpose of the Study:

• To clarify the diagnostic significance of vacuum phenomena in spinal disorders.
• To differentiate vacuum phenomena associated with degenerative disc disease from other spinal pathologies.

Main Methods:

• Review of imaging findings associated with spinal gas collections.
• Correlation of vacuum phenomena presentation with specific spinal pathologies.

Main Results:

• Vacuum phenomena are not pathognomonic for primary intervertebral osteochondrosis (degenerative disc disease).
• Gas collections can be observed in vertebral osteomyelitis, Schmorl node formation, spondylosis deformans, and vertebral collapse with osteonecrosis.
• The specific location and radiographic appearance of vacuum phenomena provide crucial diagnostic clues.

Conclusions:

• The interpretation of vacuum phenomena requires careful consideration of their context within the spine.
• Radiographic analysis of vacuum phenomena aids in differentiating between various spinal pathologies affecting the intervertebral disc and vertebral bodies.
