Minimal Invasive Spine Surgery (MISS) as a surgical approach is increasingly utilized because of the advantages it offers over conventional spine surgery. The smaller incision results in decreased tissue damage, less blood loss, decreased hospital stay & faster postoperative recovery. The drawbacks of MISS are the long learning curve of working through a smaller incision, longer length of surgery, & potential higher complication rate due to compromised visual field. These limitations can be overcome by more effectively using imaging and navigational devices. The pedicle device simplifies the hardest part of MISS instrumented fusion of conventional pedicle screw insertion by introducing a percutaneous temporary device to locate and create the channel for later conventional pedicle screw implantation using available imaging techniques. This results in faster conventional pedicle screw insertion with precision, thereby decreasing implantation error and minimizing soft tissue injury and blood loss, as well as neurological, vascular, and dural injuries and complications.
