Objective: Effectiveness and safety of Balloon Kyphoplasty as a method of treatment for osteoporotic vertebral fractures of the thoracolumbar spine.

Materials and Methods: From January 2003 to December 2008, 102 patients (27 males and 75 females), from 56 to 82 years old (mean age 72) were treated with balloon kyphoplasty procedures for 156 osteoporotic vertebral fractures of the thoracic or lumbar spine, in a mean follow up of 24 months (6 to 45 months). The patients had progressive and painful compression fractures more than 2 months. All fractures were analyzed for improvement in sagittal alignment (Cobb angle, kyphotic angle, sagittal index, vertebral height). The patients were evaluated using the visual analog scale (VAS) and the Oswestry Disability Score. Radiographs were performed postoperatively, and at 1, 3, 6, and 12 months.

Results: The score according to pain, the patient’s ability to ambulate independently and without difficulty, and the need for medications improved significantly (P < 0.001) after kyphoplasty. Vertebral height significantly increased at all postoperative intervals, with ≥10% height increases in 88% of fractures. Morphometric height ratios for treated fractures also significantly increased. There were no severe kyphoplasty-related complications, such as neurological defects, cement leakage or narrowing of the spinal canal whereas additional fractures occurred at the adjacent vertebrae at a rate of 10%.

Conclusions: Kyphoplasty provided a safe and effective treatment for pain and disability in patients with vertebral compression fractures due to osteoporosis.
