The operation by means of baloon-kyphoplasty inaugarates a method that should achieve a rapid reduction in pain and improvement of the biomechanics of the spinalcollum with a minimally technique. The purpose of the study was to investigate the therapeutic importance of baloon-kyphoplaty versus conservative treatment.

Materials and Methods

In 2001/2002 21 Patients with a functional unstable osteoporotic vertebral fracture underwent kyphoplasty surgery, and 24 patients were treated conservatievly as a comparsion group. All patients appeared for checkups several times in a period of 18 month. The following validated measuring methods were used : VAS for back pain, German version NASS Instrumentarium, Oswestry Low-Back Pain Dissability.

A native radiological diagnosis was performed on the lumbar spine and thoracic spine of all patients.


In the group of patients trated by the baloon-kyphoplasty, there where no complications during the operation. In 88% a straightening of the vertebral body was achieved. Subsequent slumping of the kyphoplastied vertrebal bodies was radiologically undetectable. In the comparsion group there was a significant higher slumpinig of the fractured vertebral bodies. 19 patients treated by the baloon-kyphoplastie stated a very satisfied pain reduction. All patient said they would be willing to have the operation repeated. A significant higher slumpening of adjacent vertebral bodies was radiologically also undetectable.


The present study results assess, for said indication, baloon-kyphoplaty as an uncomplicated and sufficient procedure for treating functionally unstable osteoporotic vertebral fractures. Pain reduction was shown to be significantly improved. Slumpening of the treated vertebral bodies can be reduced.
