Purpose

Vertebroplasty has been recognized as a powerful technique for vertebral fractures treatment, reducing the pain related with minimal risk. Sometimes, painful vertebral edema can occur in non-fractured vertebra, related to abnormal compression on the vertebral body. We evaluate the possibility to treat painful patients affected by vertebral edema using CT-guided PMMA injection in non-fractured edematous vertebral body.

Methods & Materials

Among 1244 patients undergone Vertebroplasty procedures, 8 cases were affected by focal vertebral pain related to compressive Schmorl nodes (6 patients) or thoracic totally calcified disc degeneration (2 patients). In all the patients the pain was referred during the normal day activities and even during the night, at bedrest. MRI revealed abnormal signal intensity compatible with edema inside the vertebra inferior to the Schmorl node or calcified disc, while CT scans excluded fracture and only mild sclerotic changes were appreciated. Vertebroplasty was performed with whole-body augmentation of the pathologic vertebra body.

Results

The patients became painless in 24 hours and no complication was detected at 1week-3months follow-up controls.

Conclusion

Vertebroplasty using PMMA seems to be a powerful technique in the treatment of non-fractured vertebras affected by painful edema.
