Percutaneous vertebroplasty for treatment of osteoporotic thoracolumbar vertebral compression fracture by filling auto-solidification calcium phosphate cement / 中华创伤骨科杂志

ABSTRACT

Objective To explore the clinical effect of the percutaneous vertebroplasty(PVP) and filling auto-solidification calcium phosphate cement(CPC) in treatment of osteoporotic thoracolumbar vertebral fractures. Methods From January, 2004, 26 patients with osteoporotic thoracolumbar vertebral compression fracture (29 vertebral bodies) were treated with intraoperative manipulative reduction, PVP and filling auto-solidification CPC. Results PVP were successfully performed with unilateral or bilateral vertebral pedicles for the 29 vertebrae. The average injection dose of CPC was 4.6 mL. CPC leakage occurred during the procedure in 5 vertebrae of 5 cases. All the patients were followed up for 3 to 8 months (averaging 4.6 months) and experienced complete pain relief. There was no severe complication related to the treatment. Except in 3 patients who lost 15%of the vertebral body height, the anterior height of the injured vertebral body in the other 23 patients recovered averagely to 80%of the normal one. Conclusion PVP with filling auto-solidification CPC is safe and effective in the treatment of osteoporotic thoracolumbar vertebral compression fractures.
