An adjustable intervertebral implant for implantation into a patient's spine in-between first and second adjacent or neighboring vertebrae. The implant may include one or more of the following features: (i) inner and outer members coupled by a radiographically imagable expansion ring, (ii) detachable endplates coupled to the implant via a polygonal press-fit coupling interface that accommodate a range of lordotic endplates to be applied to the implant using any surgical approach, (iii) an interference pre-loaded set screw for selectively locking the height of the construct, (iv) a radiographically imagable marker for determining the expansion of the implant, and (v) an asymmetric thread coupling between the expansion ring and the inner member.

Adjustable intervertebral implant

The present invention is directed to a low profile intervertebral implant () for implantation in an intervertebral disc space (D) in-between adjacent vertebral bodies (V). The intervertebral implant includes a plate () preferably coupled to a spacer (). The plate is preferably formed from a first material and the spacer is preferably formed from a second material, the first material being different from the second material. The plate is preferably sized and configured so that the plate does not extend beyond the perimeter of the spacer. In this manner, the plate preferably does not increase the height profile (hs) of the spacer and the plate may be implanted within the intervertebral disc space in conjunction with the spacer.

An adjustable intervertebral implant () for implantation into a patient's spine in-between first and second adjacent or neighboring vertebrae. The implant may include one or more of the following features: (i) inner () and outer () members coupled by a radiographically imageable expansion ring (), (ii) detachable endplates () coupled to the implant via a polygonal press-fit coupling interface that accommodate a range of lordotic endplates to be applied to the implant using any surgical approach, (iii) an interference pre-loaded set screw () for selectively locking the height of the construct, (iv) a radiographically imageable marker () for determining the expansion of the implant, and (v) an asymmetric thread coupling () between the expansion ring and the inner member.
