摘要:
A pedicle screw and rod system that has particular application for spinal fusion surgery. The system includes pedicle screws having ball-shaped heads that are threaded through pedicles of adjacent vertebra into the vertebral body. The system also includes two cannulated posts having a head portion with a planar portion and an opening for accepting the head of the pedicle screw in a secure and multi-axial engagement. The system further includes a tube portion that is coupled to the head portion and extends above the patient's skin. The system also includes a lordotic slotted rod that is slid down the tube portions to be positioned on top of the head portions of the posts so that the planar portions are locked within the slot. Bolts are then slid down the tube portions and are threaded to a threaded portion on the planar portion.
