Abstract

An oblique interbody spacer system includes a spacer body, a fixation plate and a plurality of angled fixation channels. The fixation plate is integrated with the spacer body such that the spacer body and fixation plate form a singular component for insertion. The implant can be affixed to the superior and inferior vertebral bodies with screws obliquely (in the range of about 30° from straight anterior).

Claims

1. An oblique interbody spacer system with integrated fixation, comprising:

a spacer body;

a fixation plate integrated with the spacer body such that the spacer body and fixation plate form a singular component for insertion; and

a plurality of angled fixation channels defined within the spacer body and fixation plate.

2. The system of claim 1, wherein the plurality of angled fixation channels include a first angled fixation channel that is angled differently with respect to the spacer body than the a second angled fixation channel.

3. The system of claim 2, further comprising a plurality of fixation members corresponding to the plurality of angled fixation channels.

4. The system of claim 3, wherein each of the plurality of fixation members is a screw.

5. The system of claim 1, further comprising a fixation member backout preventer provided to the fixation plate.

6. The system of claim 1, wherein each of the plurality of angled fixation channels defines a different trajectory.

7. A method of placing an implant into an intervertebral space of a patient, the method comprising:

employing an oblique approach to the spine to place the implant and an integrated fixation plate simultaneously into the intervertebral space; and

inserting fixation screws obliquely prior to rolling the patient over and installing a posterior hardware component.
