pedicle screw

pedicle screw

A rigid surgical implant used to stabilize adjacent spinal segments in spinal fusion surgery. Pedicle screws have been used to treat spinal disorders, including those caused by spinal cancer, congenital anomalies, trauma, and chronic pain syndromes. Potential complications may include increased pain, infection, or mechanical failure (breakage of the screws or the rods that connect them).
