Abstract
Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided intervertebral implants. The arcuate fixation members may be of different lengths, cross sectional geometries, and/or cross sectional areas. Applications of intervertebral implants utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.
Claims2
A bone fixation member configured to be inserted in a vertebral body, the bone fixation member comprising:
- a fixation body having opposing proximal and distal ends, the body including a curved intermediate portion extending between the proximal and distal ends, the distal end defining a tip configured to cut into bone;
- wherein the fixation body comprises a guidance member disposed near the tip and extending toward the proximal end, the guidance member configured to guide the tip along an insertion trajectory as the fixation member is inserted into the vertebral body.
A method for fixing an intervertebral implant in an intervertebral space defined between an upper vertebral body and a lower vertebral body, the method comprising the steps of:
- inserting the intervertebral implant into the intervertebral space, the intervertebral implant including a spacer body and a fixation plate coupled to the spacer body, the fixation plate defining a plurality of guide apertures extending therethrough;
- and
- inserting a plurality of curved bone fixation members into respective ones of the plurality of guide apertures such that at least one curved bone fixation member of the plurality of curved bone fixation members is rotationally fixed in a respective at least one of the plurality of guide apertures as the at least one curved bone fixation member is inserted into engagement with at least one of the upper and lower vertebral bodies such that, the plurality of curved bone fixation members fix the intervertebral implant to the at least one of the upper and lower vertebral bodies;
- wherein the inserting step includes guiding the at least one curved bone fixation member along an insertion trajectory through the at least one of the upper and lower vertebral bodies via a guidance member disposed at least partially along a distal end of the at least one curved bone fixation member.
