title: Percutaneous vertebroplasty under three-dimensional radiography guidance. Technical note.
abstract: An accurate, safe, and convenient method for performing percutaneous vertebroplasty (PVP) under three-dimensional (3D) radiography guidance has been developed. Six PVP procedures were performed in 5 elderly stroke patients complaining of back pain caused by compressive fracture which interfered with further rehabilitation. T(1)-weighted magnetic resonance imaging showed low intensity and T(2)-weighted imaging showed high intensity in the fractured vertebral body. The most suitable trajectory for passing the lateral mass of the lamina and pedicle, and reaching the vertebral body was identified on the axial view of 3D radiography. A 13-gauge needle was advanced appropriately in all patients, and improvement of back pain was obtained after injection of polymethylmethacrylate. No major complications occurred in any patient. PVP under 3D radiography guidance is an accurate, safe, and convenient method.
