Spine implants

摘要

An example device for the fixation and support of bone bodies includes a base member for implantation into a patient at a location between two bone bodies. The base member of the device includes an enclosed chamber for receiving fusion material and apertures for receiving bone fasteners that can be embedded into the adjacent bone bodies. The device further includes protrusions extending from the base member, wherein the protrusions are configured for engagement with one or more bone bodes upon implantation and for progressive penetration into at least one bone body over a period of time subsequent to the implantation.

主权项

1. An implant device including:
a base member configured to interface with two or more bone bodies, wherein the base member includes a primary member that forms a peripherally-surrounded bone chamber for receiving fusion material and a secondary member, contiguous with the primary member as part of the base member, that extends at an angle relative to the primary member; a plurality of interface members extending from at least one surface of the base member, the interface members being configured to provide controlled subsidence of the implant device into at least one bone body over a period of time subsequent to implantation of the device adjacent to the at least one bone body; and a plurality of bone fasteners extending through apertures provided in the base member; wherein the peripherally-surrounded chamber for receiving fusion material includes at least two interior compartments.
