SUMMARY

Objective: Report results of percutaneous vertebroplasty for treatment of osteoporotic compression fractures in the thoracic spine

Methods: There is a retrospective combined prospective study in 40 patients who had fractured thoracic vertebrae due to osteoporosis were performed vertebroplasty at Bach Mai Radiology Center from January 2018 to March 2019. Patient’s pain status was rated with Visual Analogue Scale (VAS) score and Macnab system, pre- and post-operative vertebral heights and Cobb’s angles were measured and complications were noted 1 week, 1 month, 3 months after surgery.

Results:40 patients with 56 fractured vertebraes show that there are no complications in the process of puncture needle and system complications, 12,5% cases of cement leakages into peri-vertebrae there is no case of cement cause pulmonary embolism, 5% case of pain post- operative. VAS scores were significantly reduced from 6.95 to 1.72, 86,95% has good and excellent, Cobb angle slightreduced from 14.4±9.1 to 13.2±8.5, the anteriorvertebral height slight increased from 18.5±4.3mm to 19.1±4.1mm, the middle vertebral height increases from 16.7±4.3mm to 17.4±4.3mmwith p<0.05, there is no significant changing in the post vertebral height after 3 months of intervention with p>0, 05.

Conclusion: Percutaneous vertebroplasty thoracic spine is a safe and effective method in order to provide rapid pain relief, but is less significant in improving the Cobb angle and vertebral body height.

Key words: Percutaneous vertebroplasty thoracic spine, treatment of Thoracic Fracture, pain reduction, change vertebral height.
