[Kyphoplasty in the treatment of osteoporotic spine fractures. Experience in over 500 patients].

For over 10 years, kyphoplasty has been established for the treatment of painful osteoporotic vertebral compression fractures. Its effectiveness has been substantiated in multiple clinical studies. Not only is prompt pain reduction achieved, but according to a new, large, long-term study, long-term survival is also increased. Balloon kyphoplasty was performed for 564 patients from 1 January 2008 until 31 July 2011. In all cases, pain was rated more than 6/10 points, and recent fracture was evident on cross-sectional imaging (CT or MRT) performed to supplement spine x-rays. Average patient age was 75.3 years; 71.3% of patients were female. Treated fracture levels ranged from Th3 to L5. A single level was treated in 372 cases, with two levels treated simultaneously in 128 cases, three levels in 48 cases, and four levels in 22 cases. Average operative time for all patients was 36 min. Eight different surgeons performed the procedures. Average convalescence time was 8 days which decreased progressively over the years. Pain was reduced from 8 preoperative to 2.4 points postoperative in the visual analogue scale. Six major complications (1.06%) occurred. Kyphoplasty is a good procedure to treat painful osteoporotic fractures from the lumbar to thoracic spine. Major complications occur seldom after kyphoplasty; however, they must be considered and clarified.
