Minimal invasive stabilization of osteoporotic vertebral fractures: a prospective nonrandomized comparison of vertebroplasty and balloon kyphoplasty.

Abstract

In nonrecent fractures, the reduction of the kyphotic wedge by balloon kyphoplasty was superior in decreasing pain persisting over a period of 2 years. The ability to improve disability after kyphoplasty was limited to 1 year. In nonrecent fractures, the consequences of age and osteoporosis seem to equalize the effects of the restored sagittal profile on disability but not on pain.
