Abstract:
Objective To explore clinlical outcomes of using improved computer-assisted fluoroscopic navi-gation to guide the percutaneous vertebroplasty to treat multiple osteoporotic spinal compression fractures. Methods Twenty-eight multiple osteoporotic spinal compression fractures patients with 73 painful vertebral body were got an-terio posterior,lateral and oblique radiographic imaging by using computer-assisted fluoroscopic navigation to imitate anterior- posterior. Lateral spinal and axial pedicle virtual image was obtained to guide the percutaneous kyphoplas-ty. Results All painful vertebral body were one-sided punctured,all percutaneous kyphoplasties were succeed by guiding with computer-assisted fluoroscopic navigation. Navigation virtual puncture needle image basically matched with reality view. PMMA dosage was 2.5 ～ 4 ml. Postioporational CT showed that the PMMA filled spinal focus very well. 11 cases completely relieved and 17 cases partially relieved. Conclusion Using improved computer-assisted fluoroscopic navigation to guide the PKP to treatment multiple osteoporotic spinal compression fractures decreases op-erative time and radiation injury. It is a safe,precise,minimally invasive method.
