title: New cervical laminoplasty polyethererketone cage - two case reports -.
abstract: Cervical laminoplasty is a widely used technique to enlarge the spinal canal for spinal cord decompression. The two common methods are an open door laminoplasty and a midline splitting laminoplasty. Several devices and materials have been used as a spacer for maintaining or stabilizing the lamina in the open or split position, however, some are difficult to implant. Moreover, they are not designed to restore the natural dynamics of the cervical spine, and can cause discomfort to the patient. There is a need to develop a device and material that will be effective in maintaining and stabilizing the position of the lamina after laminoplasty, being able to be implanted easily and safely to restore the natural dynamics of the cervical spine, as well as getting the bony union to the host bone. We report two cervical laminoplasty patients who were treated using a new laminoplasty polyetheretherketone cage.
