ABSTRACT
BACKGROUND: The osteoporotic vertebral compression fractures (OVCF) have attracted more and more attention due to increase in life span globally and aging population. Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) have been popularized rapidly by virtue of their unique advantage in minimal invasiveness. We analysed our results in osteoporotic thoracolumbar fractures using percutaneous kyphoplasty and posterior screw rod system. To investigate the possibility of treatment of rupture of the posterior vertebral osteoporotic fractures by means of kyphoplasty combined with the posterior screw-rod system. MATERIALS AND METHODS: Twenty six patients (65 years of age or older) with the single spine fractures included in study. The preoperative bone mineral density was measured by dual-energy X-ray. The PKP was done in all the cases. Decompression was done if neurological symptoms were present. RESULTS: The results demonstrated osteoporosis with BMD T value ≤ -2.5; injured posterior vertebral body (3 cases) had shown the whole damage accompanied by neurological symptoms through X-ray or CT. After 2 days, the remaining patients of back pain symptoms were relieved or disappeared except for three cases of patients with decompression incision. VAS score and Cobb angle changed from preoperative 8.23 ± 0.17 and 28.7 ± 0.33° respectively to postoperative 3.77 ± 0.44 and 3.8 ± 0.2° respectively. CONCLUSION: Treatment of rupture of the posterior vertebral osteoporotic thoracolumbar fractures by means of kyphoplasty combined with posterior screw-rod system is a safe, effective procedure.
