Problems solved by technology

For example, most existing laminoplasty plates are too large for insertion into small incisions or for effective attachment to the cervical vertebrae
Furthermore, existing plates often lack the stability needed to permanently position the lamina in place
Additionally, the design of existing laminoplasty plates often makes the process of attaching the plate to the vertebrae and lamina very difficult
Finally, many existing laminoplasty plates are insufficiently constructed to allow the joint use of bone amalgamation materials
Existing plates are not yet easy to use with minimally invasive surgical methods

Description

[0001] Continuing Application Information [0002] This application claims priority to US Patent Application No. 61 / 185,360, filed June 9, 2009, entitled "Laminoplasty Plate and Method of Use." technical field [0003] The present application relates generally to surgery, and more particularly to surgery for performing laminoplasty to treat cervical stenosis in the spine. More specifically, the present invention pertains to a method of increasing the area of ​​the spinal canal by securing the desired discrete lamina portions of the cervical vertebrae into a relief position. Background technique [0004] Spinal stenosis is a spinal disorder that causes narrowing of the spinal canal through which the spinal cord and nerve roots run. This narrowing can be congenital and thus can affect patients of any age. Spinal stenosis can be caused by thickening and calcification of the ligaments in the spine. For example, calcification can result from the deposition of calcium salts in ...
