Treatment of osteoporotic spinal compression fractures with percutaneous vertebroplasty / 中华创伤杂志

ABSTRACT

Objective To evaluate the curative effect and problems of X-ray fluoroscopy guided percutaneous vertebroplasty (PVP) in treating osteoporotic spinal compression fractures. Methods Twenty-four patients (15 females and 8 males) with 44 vertebral compression fractures underwent PVP. They were average 69 years of age (48-83 years). The fracture segment was within T 5-L 3 (20 thoracical vertebrae, 24 lumbar vertebrae). Under the guidance of C-arm fluoroscopy, bone marrow biopsy needle was inserted percutaneously via transpedicular way into the fractured vertebrae. Polymethylmethacrylate (PMMA) was then injected into the fractured vertebrae. Vasual analogue scale (VAS), mobility and analgesic usage were evaluated 2 days before and after PVP and in the follow-up period. Results PVP was successful in 21 cases (40 vertebrae ), but failed in 2 cases (4 vertebrae) due to weak position endurance. The volume of PMMA injected was 1.0-8.0 ml per vertebrae. The average follow-up period was 3.1 months (1-7 months). VAS was sharply decreased from pre-PVP 7.5?1.2 to 2.8?1.0 at day 2 after PVP (P
