Vertebral augmentation, including vertebroplasty and kyphoplasty, refers to similar percutaneous spinal procedures in which bone cement is injected through a small hole in the skin into a fractured vertebra in order to relieve back pain caused by a vertebral compression fracture.
Radiofrequency targeted vertebral augmentation (also written as RF-TVA) is a form of kyphoplasty that uses radiofrequency heat to control the viscosity of polymethylmethacrylate cement and deliver it into the vertebral body to treat vertebral compression fractures.
The set time can be tailored to help the physician safely apply the bone cement into the bone bed to either anchor metal or plastic prosthetic device to bone or used alone in the spine to treat osteoporotic compression fractures. Bone cement heats up during the exothermic free-radical polymerization process, which reaches temperatures of around ...
A compression fracture is a collapse of a vertebra. It may be due to trauma or due to a weakening of the vertebra (compare with burst fracture). This weakening is seen in patients with osteoporosis or osteogenesis imperfecta, lytic lesions from metastatic or primary tumors, [1] or infection. [2]
DFINE developed products for the treatment of spinal diseases using a radiofrequency platform. [1] [12] The platform covers two procedures, one for the treatment of vertebral compression fractures and one for palliative treatment of metastatic spinal tumors.
The subsidiary, called Norian, and Synthes itself, were charged with a total of 52 felonies and 44 misdemeanors, all involving an alleged conspiracy to encourage doctors to conduct unauthorized clinical trials of the company’s products on patients being treated for compression fractures of the spine, a painful condition suffered mostly by the ...
Vertebral augmentation, which includes vertebroplasty and kyphoplasty, are similar spinal procedures in which bone cement is injected through a small hole in the skin into a fractured vertebra to try to relieve back pain caused by a vertebral compression fractures.
Clay-shoveler fracture – fracture through the spinous process of a vertebra occurring at any of the lower cervical or upper thoracic vertebrae; Burst fracture – in which a vertebra breaks from a high-energy axial load; Compression fracture – a collapse of a vertebra, often resulting in the form of a wedge-shape due to larger compression ...
