Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Traumatic thoracolumbar vertebral fractures are frequently treated with posterior fixation (PF) and vertebral augmentation, but sometimes vertebral augmentation is not performed, being judged too risky under fluoroscopic guidance alone. An adjuvant CT/fluoroscopy guided percutaneous vertebroplasty (PVP) could be an option.

The aim was to evaluate feasibility, safety and effectiveness of PVP in patients with vertebral non-union (VNU) following PF performed without concomitant vertebral augmentation.

All patients treated in our institution with PVP between July 2015-July 2020 were retrospectively reviewed. Patients treated with CT/fluoroscopy guided PVP under local anesthesia for symptomatic VNU following PF were selected. Three criteria were established to assess cement distribution, considering vertebral filling of: 1)fracture cleft, 2)anterior two-thirds of the vertebral body, 3)from superior to inferior endplates. Numeric pain rating scale (NPRS) assessing grade of discomfort (0=no pain; 10=worst pain) and complications were evaluated before and one month after PVP.
