Abstract:
PURPOSE: To compare the outcome of vertebroplasty with kyphoplasty in the treatment of painful osteoporotic vertebral compression fractures. MATERIALS AND METHODS: From May 2002 through April 2004, 55 patients were analyzed. Vertebroplasties were performed on 29 patients under local anesthesia. The patients were divided into two groups: group I consisted of 15 patients who underwent vertebroplasties within two weeks from the onset of the fractures; group II consisted of 14 patients who underwent kyphoplasties after two weeks from the onset of the fractures. Kyphoplasties were performed on 26 patients under general anesthesia. These patients were also divided into two groups, based on the same criteria as those patients who underwent vertebroplasties. For the radiological assessment, we measured the kyphotic angle with Cobb's method and the reduction rate in the anterior, middle, and posterior portions of the vertebral bodies. The clinical results were assessed with the Oswestry Disability Index and Visual Analogue Scale. RESULTS: The reduction rates of the anterior and middle portions of the vertebral bodies were greater than 50 % in patients who underwent vertebroplasties within two weeks from the onset of the fractures and the patients who received kyphoplasty. The reduction rates of the anterior and middle parts of the vertebral bodies in patients who underwent vertebroplasties after two weeks from the onset of the fractures, was much less than in other three groups. There were no significant differences in clinical comparison among the 4 groups: i.e., all the patient had satisfactory results in terms of pain relief and pre-fracture activity levels. CONCLUSION: We obtained better results from kyphoplasties when we compared vertebroplasties with kyphoplasties, regardless of the operation dates. However, when we performed vertebroplasties within two weeks from the onset of the fractures, we obtained radiological results that were similar to those with kyphoplasties. In clinical comparison, there were no statistically significant differences among the 4 groups. The pain scores improved dramatically after the operations and pre-fracture activity levels resumed.
