Abstract:

BACKGROUND: Injectable polymethylmethacrylate (PMMA) with percutaneous kyphoplasty can increase vertebral strength, stabilize vertebral body, relieve pain, but its histocompatibility is poor with no biodegradability, which is easy to cause adjacent or vertebral body denaturation, even fractures.
OBJECTIVE: To observe the clinical effect of percutaneous kyphoplasty by calcium phosphate cement on osteoporotic vertebral compression fractures.
METHODS: Twenty cases of osteoporotic vertebral compression fractures were selected from the Fourth Affiliated Hospital of Harbin Medical University from 2007-12 to 2010-06. All cases were treated with injected calcium phosphate cement with percutaneoue kyphoplasty by bilateral transpedicular balloon approach. Preoperative and postoperative visual analog scale (VAS) score, X-ray, Cobb’s angle, variation of vertebral body height were measured.
RESULTS AND CONCLUSION: Average recovery height of the vertebral body was (3.38±1.44) mm (P < 0.05). The Cobb’s angle average recovery was (7.63± 2.52)° (P < 0.05). The restorations of kyphosis was (38.9±11.28)%. Preoperative VAS score was higher than that postoperative 3 days and 3 weeks (P < 0.01). Percutaneous kyphoplasty with injected calcium phosphate cement can effectively relieve the pain and treat osteoporotic vertebral compression fractures.
