Vertebroplasty in the Treatment of Spine Disease

Abstract

We report our experience in the treatment of thoracic and lumbosacral spinal pain due to vertebral bone fractures. This pathology can be related to osteoporosis but also to metastatic disease and less frequently vertebral haemangioma. From April 2001 through December 2004 we treated 238 patients for a total of 455 vertebral bodies. 175 patients had osteoporosis, 70 had metastasis and 13 had vertebral haemangioma. Sacroplasty was performed in six patients to obtain a cement filling of sacral metastasis. The procedures were mostly performed under fluoroscopy and only in cases of metastasis or sacroplasty was CT/fluoroscopy guidance preferred for optimal filling of the area of osteolysis. We evaluated the results at six and 18 months follow-up and analysed the incidence of new vertebral fractures, vascular and disk leakage and the incidence of major and minor complications. Biopsy was performed only in doubtful cases. We obtained different results considering the etiology of the disease. We obtained a 92% success rate at six months follow-up and 89% success at 18 months follow-up in osteoporosis, a 77% and 72% success rate at six and 18 months follow-up in metastastic patients, and no change at six and 18 months follow-up in patients with vertebral haemangioma in which the success rate was of 95%. We noted extravertebral leakage in 41% of vertebral bodies of which 31% were treated at the level of the vascular space and only 10% at the level of the disk space, and symptomatic in only two cases (acute compressive radiculitis, medically treated and resolved within a month). Six patients presented new fractures in the adjacent vertebral body and 30% had a partial recovery in the height of the vertebral body with kyphosis curve reduction. Vertebroplasty is a good technique to obtain spine pain relief and has a low incidence of side effects. Good quality equipment is important to obtain these results.
