To investigate the clinical results of balloon kyphoplasty in the correction of vertebral deformity (VCFs) due to osteoporosis. Methods: A prospective study was conducted on 60 patients diagnosed with VCFs at T12-L1 segment due to osteoporosis who were treated by balloon kyphoplasty at Viet Duc Hospital. Bone mineral density (BMD) levels, pain score using VAS, and the Oswestry Disability Index (ODI) for disability, the local kyphotic angle, Cobb angle and the vertebral height ratio (VHR) were measured. All patients were followed up for 6 months. Results: The effectiveness in height restoration of vertebral body from 59,3 ± 11,4% pre-op to 73,3 ± 7,9% post-op. The local kyphotic angle, and local Cobb angle improved after surgery were statistically significant and maintained after 6 months of follow-up. Average VAS score preoperative, 24h and 6 months postoperative was 6,5; 2,5; 2,8 respectively. Preoperative ODI and 6 months postoperative were 54,3% and 27,6%, respectively. There was cement leakage in 2 procedures (3,33%) and adjacent segment fracture in 2 procedures (3,33%). Conclusions: Kypholasty for patient with VCFs at thoracolubar junction T12-L1 is clinical effective.
