3 The procedure
3.1 Percutaneous insertion of craniocaudal expandable implants for vertebral compression fracture aims to restore vertebral height and augment the fractured vertebral body to relieve pain and increase mobility.
3.2 Vertebral craniocaudal expandable implants are inserted under general, regional or local anaesthesia. With the patient in a prone position, using fluoroscopic guidance, trocars are inserted through the vertebral pedicles into the vertebral body, which is then cannulated. Unexpanded implants, mounted on a bespoke instrument, are placed inside the vertebral body and expanded to restore vertebral height. High-viscosity bone cement is injected into and around each implant, filling the space in the surrounding bone.
