Abstract:
1. A cervical implant for stabilizing adjacent vertebral bodies in the cervical area, the cervical implant comprising: one or more securing means; an upper surface having a contact area configured for engaging a superior vertebrae of the adjacent vertebral bodies, a lower surface having a contact area configured for engaging an inferior vertebrae of the adjacent vertebral bodies, an outer perimeter surface extending in between said upper and lower surfaces, said outer perimeter surface including an anterior side surface, and an posterior side surface, the anterior and posterior side surfaces having superior and inferior curved edges that adjoin said outer perimeter surface to the upper and lower surfaces of the implant, respectively, and being configured to reduce frictional interference with adjacent body portions, the implant further comprising one upwardly projecting through aperture that extends through said anterior side surface and the upper surface of the implant, and one downwardly projecting through aperture that extends through said anterior side surface and the lower surface of the implant for receiving said one or more securing means, each of said through apertures having proximal and distal openings and a channel extending therebetween, said apertures having respective longitudinal axes M a retaining means for retaining said one or more securing means within said apertures, the retaining means comprising a rotatable plate securable to said anterior side surface of said implant by a rotation mount for covering said apertures of said implant at the same time when secured to prevent removal of said one or more securing means from said apertures, the plate being rotatable about said rotation mount between a first position in which said plate acts to obturate said apertures at the same time, and in a second position in which said plate acts to unobturate said apertures at the same time, said retaining means including one or more projections extending from an inner surface of said plate and configured for placement into said apertures when said plate is secured to the anterior side surface of said implant to positively engage a portion of said securing means when residing within the apertures to prevent said securing means from backing out, the retaining means further including a frictional engagement portion comprising a detent on said inner surface of the plate for engaging an edge of at least one of the apertures when deployed to resist further rotation of the plate in the obturated position relative to the implant.
