Efficacy of HA Block Kyphoplasty for Old Osteoporotic Spine Fractures

Abstract:

We have successfully treated osteoporotic spine fractures for about three years, by using transpedicular kyphoplasty with hydroxyapatite blocks (HA Block: PENTAX) (refer with: Fig. 1), The 13 patients, four men and nine women, ranged from 61 to 86 years in age (mean, 73 years). The mean Visual Analogue Scale (VAS) was 8.5 points before operation, improved to 2.7 points on the next day of operation, and improved significantly to 1.8 points at the final evaluation. The mean deformity rate (Anterior height / Posterior height x 100) was 66.3% before operation, but improved to 91.7% immediately after operation. At the time of follow-up, this rate was 78.6%, indicating that the correction loss was 13.1%. This procedure caused none of serious complications such as neurological disorder and pulmonary infarction. Kyphoplasty with HA blocks may be safe and effective in the treatment of chronic vertebral fractures.
