ReviewPercutaneous Vertebroplasty: A History of Procedure, Technology, Culture, Specialty, and Economics.
Percutaneous vertebroplasty (VP) progressed from a virtually unknown procedure to one performed on hundreds of thousands of patients annually. The development of VP provides a historically exciting case study into a rapidly adopted procedure. ⋯ It was designed as a revolutionary technique to treat vertebral body fractures with minimal side effects and was rapidly adopted and marketed in the United States. The impact of percutaneous vertebroplasty on spine surgery was profound.

ReviewPercutaneous Vertebral Body Augmentations: The State of Art.
Osteoporotic compression fractures of the vertebral body can result in pain and long-term morbidity, including spinal deformity, with increased risk of mortality resulting from associated complications. Conservative management includes opioids and other analgesics, bed rest, and a back brace. For patients with severe and disabling pain, vertebral augmentation (vertebroplasty and kyphoplasty) is often considered, with these procedures endorsed by multiple professional societies, and provides immediate structural support, and stabilizes and reinforces the weakened bone structure. The purpose of this article is to review the vertebral biomechanics, indications and contraindications, and techniques of performing successful vertebral augmentation.

This article reviews image-guided approaches for the treatment of common spine pain generators. The following treatment targets are discussed: epidural space (interlaminar and transforaminal approaches), facet joint, sacroiliac joint, and synovial cysts.

Spinal MR imaging is excellent for identifying details of spinal anatomy, including intraspinal contents, neural foramina, joints, ligaments, intervertebral discs, and bone marrow. Cortical bony structures of the spine are better imaged using CT. ⋯ Motion- and flow-related artifacts may occur during imaging and should not be mistaken for lesions. With advancements in MR imaging hardware and software, spinal MR imaging can expand its role in the delineation of normal and abnormal spinal anatomy.
