A target device for placement of implants in the thoracolumbar pedicles.
Posterior spinal instrumentation with the placement of intrapedicular implants has become an important technique. We have designed a hand-held target device to facilitate the open or percutaneous location and penetration of the thoracolumbar pedicles. A cylindrical pin guide incorporates two metal rings and can be moved under image intensifier control until the rings are superimposed to show correct alignment. The radiation dosage for the surgeon is minimal; the device allowed accurate placement of 106 consecutive pedicle screws.
