Abstract:

 Objective To evaluate the clinical effect of a kind of balloon kyphoplasty（C-pod kyphoplasty）in the treatment of osteoporotic thoracic vertebral compression fractures. Methods From December 2014 to March 2016, 21 cases of osteoporotic vertebral compression fractures in 25 vertebral bodies were treated with catheter fabrickyphoplasty. VAS and ODI were recorded before operation and within 24 hours after operation and the last follow?up. The changes of vertebral kyphosis Cobb angle were measured before operation and after operation and at the last follow?up. Results All cases were followed up 6 to33 months（average 15.3 months）. Before the operation, the VAS score was 7.6 ± 1.2, the ODI score was 87.4±11.5, and the cobb was 21±4.6. In 24 hours after the operation, the VAS score was 2.4± 0.6, the ODI score was 43.8±9.6, and the cobb was 5.8±0.6. In the final follow?up, the VAS score was 2.1±0.4, the ODI score was 42.6±10.1, and the cobb was 6.4±0.7.The VAS, ODI score and Cobb angle were significantly improved after operation and in the last follow-up, the differences were statistically significant. There was no significant difference in VAS, ODI score and Cobb angle between 24 hours after operation and the last follow-up. Conclusion The curative effect of C-pod kyphoplasty was good and in treating osteoporotic thoracic vertebral fracture. It can reduce the leakage of bone cement during the operation.
