Introduction: During the last years minimal-invasive augmentation techniques of vertebral bodies have been established to stabilize painful height losses. Kyphoplasty was described in osteoporotic fractures for stabilisation and high restoration of the collapsed vertebral body. Kyphoplasty intends to achieve a reduction of kyphosis prior to cementing.

Aim: The study was performed to analyze the Kyphoplasty technique in patients with tumour induced back pain due to affected vertebral bodies.

Method: 7 Patients with Tumour induced back pain were enrolled. MRI, CT and x-ray were performed to confirm the diagnosis and for staging. All patients have severe and significant back pain. Primary spine tumours were excluded. To evaluate the clinical outcome the Oswestry

Score and McNab Score were used. CT scans after procedure were performed to detect cement extrusion. The follow up examinations 12 weeks after Kyphoplasty were performed by an independent blinded observer.

Results: 6 patients complete 12 week follow up. All subjects reported significant subjective improvement on the McNab Score (2 excellent, 3 good,1 moderate outcome.) Oswestry Score showed the same results (74±12 Pts at Baseline and 28±9 at 12 week follow up).
