Abstract

An intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The implant includes a spacer portion, a plate portion operatively coupled to the spacer portion and one or more blades for securing the implant to the adjacent vertebral bodies. The blades preferably include superior and inferior cylindrical pins for engaging the adjacent vertebral bodies. The implant may be configured to be inserted via a direct lateral trans-psoas approach. Alternatively, the implant may be configured for insertion via an anterior approach.

Claims16

Dependent claims

An intervertebral implant for insertion into an intervertebral disc space between a firsts vertebral body and a second vertebral body, the implant comprising:

a spacer portion having a top surface for contacting the first vertebral body, a bottom surface for contacting the second vertebral body, a first side surface, a second side surface, a leading surface, and a trailing surface, the first and second side surfaces each have a length that is longer than a length of each of the leading and trailing surfaces;
a plate portion having a top surface, a bottom surface, a first side surface, a second side surface, a leading surface for operatively contacting the trailing surface of the spacer portion and a trailing surface, the plate portion being coupled to the spacer portion;
and
a first cylindrical securement member supported by the plate portion and spaced in its entirety superiorly relative to the top surface of the spacer portion, wherein the first cylindrical securement member is configured to be received in the first vertebral body;
and
a second cylindrical securement member supported by the plate portion and spaced in its entirety inferiorly relative to the bottom surface of the spacer portion, wherein the second cylindrical securement member is configured to be received in the second vertebral body.

3 more elements

A method for inserting an intervertebral implant into a disc space between a first vertebral body and a second vertebral body, the method comprising the steps of:

coupling the intervertebral implant to the insertion instrument, wherein the intervertebral implant includes a spacer portion having a leading end and a trailing end, and a plate portion coupled to the trailing end;
forming a passageway to the disc space;
inserting the spacer into the disc space along an insertion direction defined from the trailing end to the leading end;
inserting a first cylindrical securement member into the first vertebral body, wherein the first cylindrical securement member is supported by the plate portion after the step of inserting the first cylindrical securement member has been completed;
and
inserting a second cylindrical securement member into the second vertebral body, wherein the second cylindrical securement member is supported by the plate portion after the step of inserting the second cylindrical securement member has been completed,
wherein an entirety of the first cylindrical securement member is spaced superiorly from the spacer portion, and an entirety of the second cylindrical securement member is spaced inferiorly from the spacer portion.
