Observation on recurrent vertebral compression fracture after percutaneous vertebroplasty for the patients with osteoporosis

Objective To explore the risk factors of recurrent vertebral compression fracture after percutaneous vertebroplasty (PVP) for osteoporosis. Methods One hundred and six patients with osteoporotic vertebral compression fracture were randomly divided into PVP group (n=65) and conservative group (n=41) . The patients in the two groups received PVP or conservative therapy respectively. The effects were observed according to the McGill questionnaire score (PRI) at one month and two years after the treatment. And the recurrent vertebral compression fracture were analyzed after 2 years. Results At 1 month and 2 years after treatment, the PRI of PVP group (5.71±3.56; 10.45±5.11) were significantly lower than the conservative group (16.75±5.25; 24.67±5.09) . The difference was statistically significant (P 0.05) . Conclusion PVP for osteoporosis can relieve the pain of patients with osteoporotic vertebral compression fracture, and it does not increase the risk of recurrent vertebral compression fractures within two years after treatment.
