Abstract
An interbody implant includes an implant body extending between an anterior surface and a posterior surface. The implant body includes a first vertebral engaging surface and a second vertebral engaging surface. At least one of the vertebral engaging surfaces defines a cavity configured for disposal of bone growth detectable via medical imaging. Systems, spinal constructs, surgical instruments and methods are disclosed.
Claims20
An interbody implant comprising:
- a body extending between opposite first and second end surfaces, the body including opposite first and second side surfaces each extending from the first end surface to the second end surface, the body including opposite first and second vertebral engaging surfaces each extending from the first end surface to the second end surface and from the first side surface to the second side surface, the end surfaces, the side surfaces and the vertebral engaging surfaces defining a cavity, the body defining a passageway extending through the side surfaces, the passageway being spaced apart from the cavity, the passageway having a cylindrical cross-section, the first end surface defining a slot, the first vertebral engaging surface defining a track, the cavity being positioned between the slot and the passageway, the slot and the track being in communication with the cavity;
- and
- a slider having a first portion movably disposed in the track and a second portion movably dispose in the slot,
- wherein the first vertebral engaging surface comprises a plurality of spaced apart apertures, and the passageway is not in communication with the apertures.

An interbody implant comprising:
- a body extending along a longitudinal axis between opposite first and second end surfaces, the body including opposite first and second side surfaces each extending from the first end surface to the second end surface, the body including opposite first and second vertebral engaging surfaces each extending from the first end surface to the second end surface and from the first side surface to the second side surface, the end surfaces, the side surfaces and the vertebral engaging surfaces defining a cavity, the body defining a passageway extending through the side surfaces, the passageway being spaced apart from the cavity such that the passageway is not in communication with the cavity, the passageway having a cylindrical cross-section, the vertebral engaging surfaces each having a honeycomb configuration defining a plurality of apertures, the apertures being spaced apart from the passageway such that the apertures are not in communication with the passageway, the first end surface defining a slot, the first vertebral engaging surface defining a track, the cavity being positioned between the slot and the passageway, the slot and the track being in communication with the cavity;
- and
- a slider having a first portion movably disposed in the track and a second portion movably dispose in the slot, the second portion including a threaded post,
- wherein the body is configured to be manipulated between a non-aligned orientation in which the passageway has a non-circular configuration when viewed along a line of sight and an aligned orientation in which the passageway a circular configuration when viewed along the line of sight.

An interbody implant comprising:
- a body extending along a longitudinal axis between opposite first and second end surfaces, the body including opposite first and second side surfaces each extending from the first end surface to the second end surface, the body including opposite first and second vertebral engaging surfaces each extending from the first end surface to the second end surface and from the first side surface to the second side surface, the end surfaces, the side surfaces and the vertebral engaging surfaces defining a cavity, the body defining a passageway extending through the side surfaces, the passageway having a cylindrical cross-section, the passageway being the cavity such that the passageway is not in communication with the cavity, the body including a recess extending into the first side surface, the vertebral engaging surfaces each having a honeycomb configuration defining a plurality of apertures, the apertures being spaced apart from the passageway such that the apertures are not in communication with the passageway, the side surfaces and the vertebral engaging surfaces converging with the first end surface to define a bullet nose, the passageway extending through the nose, the first end surface defining a slot, the first vertebral engaging surface defining a track, the cavity being positioned between the slot and the passageway, the slot and the track being in communication with the cavity;
- and
- a slider having a first portion movably disposed in the track and a second portion movably disposed in the slot, the second portion including a post, the post defining a female thread,
- wherein the recess is disposable between a non-aligned orientation in which the first side surface prevents visualization of the recess and an aligned orientation in which the first side surface is oriented to allow visualization of the recess through the body.
