    摘要: A method of manufacturing a curved spinal rod is disclosed. The method includes heating PEEK; injecting the PEEK into an arcuate spinal rod mold; holding the injected PEEK in the mold until the PEEK substantially sets; and removing the injected PEEK from the mold. In another aspect, a spinal rod is disclosed. The spinal rod includes an arcuate main body having a first end portion, a second end portion, and a central portion. The central portion has a non-circular cross-section with a height greater than its width. The first and second end portions and the central portion of the arcuate main body are integrally formed of a polymer such as polyetheretherketone (PEEK). The spinal rod also includes a rounded end cap adapted to mate with at least one of the end portions. The end cap is radiopaque.

    摘要: An intervertebral process brace is disclosed and can include a frame that can support a first vertebral process and a second vertebral process. The intervertebral process brace can also include a first vertebral process support strap that can span a first portion of the frame. The first vertebral process support strap can engage the first vertebral process and bind the first vertebral process between the first vertebral process support strap and the first portion of the frame.
