Bone tamps designed as inflatable balloons intended to perform dilatation of vertebral bone cavities during percutaneous procedures. These devices typically consist of flexible balloons with radiopaque markers that are inflated with contrast media after appropriate positioned positioning inside the vertebra using a small-diameter hollow cannula attached to a syringe. Both the balloon and the cannulae are available in several sizes. Vertebral cavity expansion balloons are mainly used during kyphoplasty procedures to expand the vertebral cavities prior to filling with orthopedic cement; the procedure is intended for the treatment of vertebral compression fractures.
