Comparative efficacy of vertebroplasty, kyphoplasty, and medical therapy for vertebral fractures on survival and prevention of recurrent fractures

To evaluate the efficacy of surgical and medical therapies on recurrent vertebral fracture and mortality rates. A retrospective review of medical records was performed of patients seen at Emory University Spine Center and Hospital (Atlanta, Georgia) for vertebral fracture between 1998 and 2007. Patients with vertebral fracture or who underwent vertebroplasty or kyphoplasty were identified by use of the International Classification of Diseases, Ninth Revision and Current Procedural Terminology codes, respectively. Outcome measures included site and date of recurrent vertebral fractures and mortality. We identified 250 patients with vertebral fractures and classified them into 4 groups: surgical therapy only, surgical plus medical treatment, medical therapy only, and no treatment. There was no significant difference in the cumulative survival rates among the 4 study groups nor between the treatment groups. There was, however, a significant difference in the cumulative refracture-free rates among the 4 study groups (P
