Purpose: To evaluate the clinical outcome of the extrapedicular approach of
percutaneous vertebroplasty (PVP) for upper and mid-thoracic vertebral compression
fractures in patients.


Material and Methods: Extrapedicular vertebroplasty was performed in painful
compression fractures at T4?T8 levels. The assessment criteria were changes over time
in visual analog scale (VAS) and mobility score. We evaluated the volume of cement
injected, the size of needle required, and complications.


Results: Procedures were performed in 27 patients with a total of 34 affected vertebral
bodies. Early (within a week) and one year later, clinical follow-ups showed that pain
intensity had decreased by 50% one day after operation and later by 70?80%. Mobility
scores of all patients were improved immediately after the procedure. Average volume of
polymethylmethacrylate (PMMA) per vertebral body was 3.8¡1.2 ml. Leakage of
PMMA occurred in one vertebral level (intradiskal space), but did not cause clinical
complications.


Conclusion: PVP of upper and mid-thoracic spine with an extrapedicular approach is an
efficient and safe procedure for treating painful thoracic vertebral compression fracture
under a cautious patient selection and meticulous technical procedure.


Key words: Spine; treatment effects; vertebroplasty
