Clinical Application of Percutaneous Vertebroplasty in Treatment of Senile Osteoporosis Spinal Compression Fractures

Objective To observe the clinic outcome of the percutaneous vertebroplasty (PVP) in treatment of senile osteoporosis spinal compression fracture. Methods From January 2006 to January 2009,147 patients (91 females and 56 males) with 214 verteral compression fractures underwent PVP with an average of 69 years old ranged from 61 to 80. The fracture segments were within T8-L3 (98 thoracical vertebrae,116 lumbar vertebrae). Under the guidance of C-arm fluorosecopy,bone marrow biopsy needle was inserted percutaneously via transpedicular way into the fractured vertebrae. Polymethylmethacrylate (PMMA) was then injected into the fractured vertebrae. The anterior and posterior edge of the vertebral body were measured and calculated the rate before and after PVP. The outcome was evaluated by WHO standard. Results A total of 118 cases were followed up for 3 to 7 months,and the average follow-up period was 4 months. PVP was successful in 147 cases (214 vertebrae). The volume of PMMA injected was 1.0-8.0 mL per vertebrae. The low back pain was remarkable remitted 2 to 4 hours after operation,and there was no any notable complication encountered. Comparing to preoperation,the rate of the anterior edge to posterior edge had no significant difference after operation,the CR+PR rate was 100%. Conclusions PVP is an effective minimal invasive technology,which can rapidly remit the low back pain caused by the senile osteoporosis vertebral compression fracture,reinforce the intensity of the vertebral body and stabilize the spine.
