Efficacy of percutaneous kyphoplasty for osteoporosis vertebral compression fractures

Abstract

Objective To conclude the technology and clinical outcomes of percutaneous kyphoplasty for the treatment of osteoporotic vertebral compression fractures. Methods From June 2011 to June 2014, 29 cases of osteoporoticthoracic and lumbar vertebral compression fractures patients, who were diagnosed by ultrasonic bone mineral density measurement. X-ray, CT and MRI were treated with percutaneous kyphoplasty in Beijing 401 Hospital of China Nuclear Industry. Observed and recorded the degree of pain, patient's activity and the recovery of vertebral height in patients with 24 hours, 3 months and 6 months after operation. The index data were analyzed by SPSS17.0 statistical software, and the measurement data were analyzed by paired t test. Results Twenty-nine patients were operated successfully, 17 cases (58.62%)of back pain disappeared and 12 cases (41.38%) of back pain significantly reduced. Twenty-seven cases (93.1%) were allowed to get off bed after 24 hours of operation and 2 cases (6.9%) after 3 days. Three cases (10.34%) occurred PMMA leakage. After 24 hours, 3 months and 6 months VAS and vertebral height of the original vertebral height percentages are much better than before surgery (P 0.05). Compared after surgery 3-month and 6-month with after surgery 24 hours, the vertebral height have lost, but the lost height of the vertebral was no statistical significance (P>0.05). No infection, hematoma, spinal nerve injury and PMMA poisoning complications occurred. Conclusions Percutaneous kyphoplasty can relieve the pain and restore part of the vertebral height satisfactory with better outcomes.
