Spine Alignment During Pedicle Screw Fixation

In the cervical spine, the use of the pedicle screw is limited due to the flexibility of the cervical spine which makes placing the screws highly difficult. A device has been designed that uses clamps and rails to maintain spinal stabilization for pedicle screw placement during spinal surgery. This device ensures that optimal spine positioning is obtained, thus eliminating the chance of spinal movement during placement of a pedicle screw. Of the 200,000-plus spinal surgeries that are done in the U.S., pedicle screw fixation is the most common surgical technique used to stabilize the spine for patients with spinal degeneration, fracture, or scoliotic deformity. The effectiveness of this surgery is contingent on the accuracy of the screw placement.

Pedicle Screw Placement Accuracy

The cervical spine alignment and stabilzation device aligns and fixes the cervical vertebrae during surgery so that screw placement is more accurate. Increasing the accuracy of the screw placement will not only lead to greater use of pedicle screws in surgery, but will help reduce screw revision rates and improve patient outcomes. Another advantage is that this device is not limited to surgeries with pedicle screw placement, it also has potential applications in spinal fusion surgery and spinal reconstruction surgery.
