Abstract

Methods

 

This prospective study included 27 patients diagnosed with VCF (Magerl classification A.1.2, A.1.3, and A.3.1) of the thoracolumbar spine treated with percutaneous cement augmentation using the SpineJack® device. The study was conducted in Valladolid University Hospital, Valladolid, Spain from January to December 2012, with a minimum one-year follow up.
Preoperative evaluation included visual analogue scale (VAS) for pain, and radiological assessment of the VCF using 3-dimensional computed tomography (3D-CT) scans for measurements of vertebral heights and angles. The patients were followed at 3, 6, and 12 months with clinical VAS and radiological assessments.

Results

The procedure was performed in 27 patients with a mean age of 55.9 ± 17.3 years, 55.6% females. All patients underwent surgery within 6 weeks from time of injury. No procedure related complications occurred. Pain measured by VAS score decreased from 7.0 preoperatively to 3.2 within 24 hours, and remained 2.2 at 3 months, 2.1 at 6 months, and 1.5 at 12-months follow-up (p<0.05). Mean height restorations for the anterior was 3.56 mm, central was 2.49, and posterior vertebral was 1.28 mm, and maintained at 12-months follow-up (p=0.001).

Conclusion

This new percutaneous technique for VCF has shown good clinical results in pain control and the possibility to reduce both vertebral kyphosis angles and fractured endplates seen in 3D-CT scans assessment method. Further studies are needed to confirm those results on larger cohorts with long-term follow up.
