摘要:
The various embodiments described herein provide lateral mass and facet fixation implants, which may be inserted and applied via a posterior approach, using minimally invasive or less invasive techniques. The embodiments described below generally include an intrafacet implant (or “facet implant”) and a lateral mass fixation member attached to or attachable to the facet implant. The lateral mass fixation member can include one or more tabs extending from a middle portion and configured to secure the lateral mass fixation member to lateral masses of adjacent vertebrae. The tabs may be flexible, semi-rigid, or rigid, and may be collapsible to facilitate insertion of the device. Methods for delivering the lateral mass and facet fixation implants are also described.
