Spinal Implants

摘要

Disclosed are improved spinal implants that are configured to help prevent post-operative migration of the implant. In some embodiments, the implant system includes multi-axial tooth geometry and other geometrical configurations such as but not limited to peripheral curvatures that aid in the prevention of such post-operative migration. Also disclosed are asymmetrical implants having superior and inferior surfaces with different angulations relative to the sagittal midline.

主权项

1. A spinal implant device comprising:
a body for holding graft material therein, the body comprising: a sagittal midline; a posterior edge and an anterior edge opposite the posterior edge; a superior surface and an inferior surface opposite the inferior surface, at least one of the superior surface and the inferior surface comprising a plurality of teeth; wherein the plurality of teeth comprises a first row of outer teeth positioned along the anterior edge of the body and a second row of inner teeth positioned inwardly from the first row of outer teeth; and wherein the inner teeth of the second row project further from the sagittal midline than an outwardly adjacent outer tooth of the first row of outer teeth.
