Percutaneous extrapedicular vertebroplasty with expandable intravertebral implant in compression vertebral body fracture in pediatric patient-technical note.
OBJECTIVE
The aim of the article is to present the new extrapedicular percutaneous technique for posttraumatic vertebral column fracture.


METHODS
A 15-year-old boy needed a surgical Th8 posttraumatic vertebral body (VB) compressive fracture reduction due to insufficient conservative treatment and consistent severe clinical symptoms. After 6 months of external Jevett long-roll brace stabilization, progressive sagittal balance disturbance of thoracic kyphosis was measured and persistent clinical symptoms were observed. It was decided to present a surgical technique method allowing to attempt to reduce VB fracture, rebalance the vertebral column (VC) without any motion limitation, and decrease clinical symptoms. The procedure was performed percutaneously from extrapedicular approach with intravertebral implant (Spine Jack®-Vexim™) and cement (Interface®-Vexim™) under fluoroscopic imaging (Ziehm™ 8000®).


RESULTS
The whole procedure was uneventful. Now, the child is free from clinical symptoms and the partial reduction of VB fracture was achieved. The patient has been followed for 3 months. In the control CT scans, the VB fracture reduction is stable and no progression of thoracic kyphosis angle is observed. Furthermore since the surgical procedure, the patient is clinical symptom free.


CONCLUSIONS
The extrapedicular percutaneus technique of VB fracture reduction with intravertebral fixation allowed to partially reduce the VB compressive fracture, rebalance the VC without any motion limitation, avoid external long-roll brace, and eliminate clinical symptoms. The procedure is minimally invasive, fast, and clinically effective. However, the technique should be restricted only to carefully selected clinical cases.
