Percutaneous vertebroplasty with polymethylmethacrylate (PMMA) is used increasingly for pain relief in symptomatic neoplastic or osteoporotic compression fractures. However, restoration of the stiffness of the treated vertebrae might propagate secondary fracture of adjacent vertebrae. Elastoplasty might prevent these secondary fractures. We assessed retrospectively our experience with elastoplasty in 12 patients, focusing on silicone migration. During the period from July 2011 to January 2012, all patients with an indication for vertebroplasty were treated with elastoplasty. The exclusion criterion was the presence of posterior wall defects. Chest computed tomography (CT) scans were performed to evaluate the presence of perivertebral leakage and pulmonary embolism. The prevalence of leakage was compared with the results obtained for vertebroplasty with PMMA reported in the literature. Other complications during the postprocedural period were recorded. Twenty-one vertebral bodies in 12 patients were treated with elastoplasty. Silicone pulmonary emboli were detected on the postprocedural chest CT in 60 % (6/10) of the patients. Leakage to the perivertebral venous plexus was seen in 67 % (14/21) of the treated vertebrae. One major complication occurred: severe, medication-resistant dyspnea developed in one patient with multiple peripheral silicone emboli. This preliminary evidence suggests that VK100 silicone cement should not be used in elastoplasty because of the increased risk of silicone pulmonary embolism, when compared with the use of PMMA, which occurs worldwide. The major technical disadvantage is that the time taken for the VK100 silicone material to achieve its final strength is too long for practical application.
