Balloon Kyphoplasty under Three-dimensional Radiography Guidance
Percutaneous balloon kyphoplasty (PBKP) is generally performed under two-dimensional (2D) radiography guidance (lateral- and anteroposterior (A-P) views) using C-arm fluoroscopy. However, 2D images taken by single-plane or bi-plane fluoroscopy cannot provide information regarding axial views, particularly the Z axis. Lack of information regarding the Z axis prevents the creation of three-dimens...
متن کاملIntraoperative three-dimensional fluoroscopy-based computerized tomography guidance for percutaneous kyphoplasty.
OBJECT Percutaneous kyphoplasty is an established method for the treatment of pathological vertebral compression fractures (VCFs). This procedure is usually performed with the aid of biplanar fluoroscopic image guidance. There are currently no published clinical studies in which the use of three-dimensional (3D) image guidance to facilitate this technique has been evaluated. The purpose of this...
متن کاملBalloon-Kyphoplasty for Vertebral Compression Fractures
• pathologic fractures, as for: • osteoporosis (the most common cause: about 750,000 people per year in United States): in people with severe osteoporosis, a VCF may be caused by simple daily activities, such as stepping out of the shower, sneezing vigorously or lifting a light object; • metastatic tumors; • multiple myeloma; • vertebral hemangiomas; • traumatic fractures, which can occur with ...
متن کاملBalloon kyphoplasty: an evidence-based analysis.
OBJECTIVE To review the evidence on the effectiveness and cost-effectiveness of balloon kyphoplasty for the treatment of vertebral compression fractures (VCFs). CLINICAL NEED Vertebral compression fractures are one of the most common types of osteoporotic fractures. They can lead to chronic pain and spinal deformity. They are caused when the vertebral body (the thick block of bone at the fron...
متن کاملA Three-dimensional Predictive Entry Guidance Approach
The Space Shuttle’s two-dimensional entry trajectory planning method is extended to three dimensions. Both angle-of-attack and angle-of-bank variations are used to control the entry trajectory. The trajectory planning is done with a third-order system of differential equations using the drag and lateral accelerations as intermediate controls. The reduced-order planning problem is solved first i...
