To evaluate the clinical and radiographic outcomes of balloon kyphoplasty in patients with fractures of the thoracic and lumbar spine caused by metastatic disease.


64 balloon kyphoplasty procedures were performed in 31 patients (18 females and 13 males with bone metastasis), 28 of whom were followed up over a period of 1 year. Symptomatic levels were identified by clinical presentation, magnetic resonance imaging (MRI), radiographs, and computed tomography (CT). In the prospective 1-year follow-up, visual analog scale (VAS) and Oswestry Disability Score were documented. Radiographs were performed pre- and postoperatively, and at 3, 6, and 12 months. Vertebral height and kyphotic deformity were measured to assess restoration of the sagittal alignment.


The median pain scores (VAS) decreased significantly (P<0.05) from pre- to post-treatment, as did the Oswestry Disability Score (P<0.05). Polymethyl methacrylate (PMMA) cement leakage was detected in eight of 64 vertebral bodies (12.5%), but did not have any clinical relevance. During 1-year follow-up, balloon kyphoplasty stabilized vertebral height and prevented further kyphotic deformity.


Balloon kyphoplasty is an effective, minimally invasive procedure for the stabilization of pathological vertebral fractures caused by osteolytic lesions of vertebral bodies due to metastatic disease. It gives a statistically significant reduction of pain and prevents further kyphotic deformity of the spine.
