Cone-beam CT: Just as useful as MDCT before and after percutaneous vertebroplasty
November 04, 2008Cone-beam CT which is believed to deliver less radiation than MDCT is just as useful when evaluating patients before and after percutaneous vertebroplasty according to a study performed at the Department of Clinical Radiology, Kyushu University, Fukoka, Japan. Percutaneous vertebroplasty is a minimally invasive cement augmentation technique to relieve pain in the back that is non-responsive to conservative treatment.
The study included 22 patients who had osteoporotic compression fractures and underwent percutaneous vertebroplasty for treatment. During the study cone-beam CT and MDCT were performed on all patients before and after percutaneous vertebroplasty. Before vertebroplasty, all 75 cortical defects seen on MDCT were also observed on cone-beam CT with 100% sensitivity and specificity. After vertebroplasty, MDCT found cement leakages in 17 disk spaces, 15 paravertebral soft tissues and 12 veins; cone-beam CT identified all cement leakages.
"While there is no gross difference between MDCT and cone-beam CT, cone-beam CT is believed to deliver less radiation," said Akio Hiwatashi, MD, lead author of the study.
Percutaneous vertebroplasty is common throughout the United States and European countries. It is often used when conservative treatments like pain medication, activity limitation, physical therapy and bracing is not enough.
"Patients can be safely evaluated before and after vertebroplasty using the cone-beam CT system. It is a technical advance in image guided intervention," said Dr. Hiwatashi.

Vertebroplasty Current Events and Vertebroplasty News RSSNew expensive back procedure exposed as ineffective
A world-first study involving Monash University and the Cabrini Research Institute in Melbourne has revealed the injection of bone cement into broken vertebrae is not an effective treatment for patients suffering painful osteoporotic fractures.
Metastatic bone disease patients can walk in Lazarus' footsteps
Osteoplasty-a highly effective minimally invasive procedure to treat the painful effects of metastatic bone disease by injecting bone cement to support weakened bones-provides immediate and substantial pain relief, often presenting individuals who are suffering terribly with the miraculous so-called "Lazarus effect," according to researchers at the Society of Interventional Radiology's 34th Annual Scientific Meeting.
Engineers developing new cements to heal spinal fractures
New research could offer hope for victims of the most devastating spinal injuries - typically those caused in car crashes.
Studies unclear whether spinal cement procedure improves back pain
A procedure that fills in fractured vertebrae with injected cement has not been shown to improve a person's back pain or quality of life, according to a new analysis of studies.
New technique offers relief for patients with spinal tumors
A radiologist at the University of California, San Diego (UCSD) School of Medicine has developed a new procedure to treat fractured vertebrae caused by spinal tumors, a procedure that may decrease the risk of complications, which are experienced by 5 to 10% of patients with malignant tumors of the spine.
Vertebroplasty heals fractures but may cause others, Mayo Clinic study finds
A new Mayo Clinic study finds that vertebroplasty, a procedure used to treat painful compression fractures in the spinal vertebrae due to osteoporosis, appears to increase the risk for new fractures in adjacent vertebrae.
Vertebroplasty improves back pain, activity level, Mayo Clinic study reports
A Mayo Clinic study has found patients report less back pain at rest and while active following vertebroplasty, a procedure in which medical cement is injected into painful compression fractures in the spinal vertebrae due to osteoporosis.
Hope for People with Severe Spine Fractures
LEEDS UNIVERSITY is at the forefront of research into implant technology and that research is just about to take a big leap forward in the spinal injuries sphere. A new laboratory, The Frank Parkinson Tissue Engineering Laboratory, has just opened. It contains what is believed to be the world's first simulator capable of replicating the conditions of the human body to allow researchers to analyse how the spine might react to spine surgery techniques - the Prosim Spinal Biomechanical Fatigue Simulator. The simulator was developed by Simulation Solutions, a company with several years experience in the design and manufacture of knee, hip and friction simulators used in the testing of prosthetic
Engineering to protect brittle bones
Leeds University engineer Dr Ruth Wilcox, 27, is on a mission - to help people with the brittle bone disease osteoporosis. She has just won a Post-Doctoral Research Fellowship from the Royal Academy of Engineering, starting 1 August, which will enable her to devote the next five years of her research to improving treatment of patients with osteoporosis and other painful bone disorders. Ruth's main focus is to optimise a technique called percutaneous vertebroplasty (PVP), which can be used to treat vertebral compression fractures, suffered by many elderly people with osteoporosis. PVP involves injecting special bone cement into the vertebrae of the spine to stabilise them - it is minimally in

Percutaneous Vertebroplasty and Kyphoplasty by John M. Mathis (Editor), Hervé Deramond (Editor), Stephen M. Belkoff (Editor) This Second Edition has been thoroughly revised to reflect recent advances in the field of percutaneous vertebroplasty. Obsolete sections have been replaced with cutting-edge material, such as an in-depth look at the latest bone cements and devices. Chapters outline spine anatomy, medical management, and patient selection. The text is enhanced by a wealth of illustrations. The addition of practical and challenging case studies furthers the focus of the previous edition by bridging the gap between theory and practice for spine interventionalists, radiologists, neuroradiologists, orthopedic surgeons, and neurosurgeons. New to the Second Edition: - New data on alternate routes for therapy, sacroplasty, and treating tumors - New treatment techniques - Updated examination of biomechanics... |

Vertebroplasty and Kyphoplasty by Daniel Resnick (Editor), John Barr (Editor), Steven R Garfin (Editor) Vertebroplasty and kyphoplasty are two new procedures introduced in the past five years to treat pain from osteoporotic compression fractures. These procedures are carried out by neurosurgeons, orthopedic surgeons, and interventional radiologists - and the popularity of these procedures is growing. Because vertebroplasty and kyphoplasty were introduced recently, there is little information available on them. This book will fill this gap in literature. |
