Embodiment Construction

[0056] Spinal stenosis reflects a narrowing of one or more regions of the spine, usually in the upper or lower back. This narrowing can put pressure on the spinal cord or the nerves branching from the compressed area. The individual vertebrae of the spine are positioned relative to each other and are kept separate by separating the intervertebral discs of the main vertebrae and the capsules located within the facet joints. The discs and capsules are separated from the bone of their respective joints by cartilage. Spinal stenosis usually indicates degeneration of the discs, capsules, or cartilage in the joints, which can lead to joint compression and the aforementioned narrowing.

[0057] To relieve spinal stenosis, distract two adjacent vertebrae of the spine (eg, figure 1 Options for the cervical spine shown in ) are varied and can include the use of implants, or cages and screws. In many cases, the facet joint implant can be inserted into the facet joint itself, and due t...

Abstract

A spinal fixation access and delivery system is disclosed. In some aspects, the system is used to access the cervical facet joint via a posterior access approach. The system may include an access device including a body having a proximal portion and a distal portion and a chamfered or beveled end feature positioned at the distal portion of the body and configured for insertion at the cervical facet joint. The system may further include a guide device having access device engagement features and a spinal fixation member. The access device includes at least one guide device receiving feature complementary to or keyed to the engagement feature of the guide device.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Patent Application No. 62 / 508,434, filed May 19, 2017, entitled "SPINALFIXATION ACCESS AND DELIVERY SYSTEM," which is hereby incorporated by reference in its entirety. into this article. technical field [0003] The present application relates to medical devices and methods. More specifically, the present application relates to devices and methods related to spinal fixation to provide stability to the spine and promote spinal fusion. Background technique [0004] Chronic low back problems are one of the most common causes of pain and disability in the United States and other developed countries. By at least one estimate, the most common surgical procedure in the United States is a spinal fusion procedure that uses plates, screws and other implants to fuse two adjacent vertebrae together. The purpose of performing spinal fusion is to attempt to increase the space between the t...
