Introduction: Segmental spinal deformity results from vertebral compression fracture (VCF) and progressive collapse of the fractured vertebral body (VB). The VB stenting (VBS) systemⓇ comprises a balloon-assisted, expandable, intrasomatic, metal stent that helps maintain the restored VB during balloon removal and cement injection, which minimizes cement leakage. We performed a prospective, multicenter, clinical trial of the VBS system in Japanese patients with acute VCF owing to primary osteoporosis.
