Equipment

Biplane or singleplane fluoroscopy technique.
  • Facilitating the rapid acquisition of guidance information in two planes, biplane fluoroscopic equipment is particularly recommended for beginners. If a biplane system is not available, one may be simulated by adding a mobile C-arm to the room with a fixed single-plane system, thus creating temporary biplane configuration that will speed the procedure. The higher quality image should be used for lateral projection because that projection is the most critical for monitoring cement injection.
  • The biplane fluoroscopic equipment allows multiplanar, real-time visualization for cannula introduction and cement injection and distribution in the vertebral body.  Rapid alternation between imaging planes is possible without complex equipment moves or projection realignment.
