An adjustable intervertebral implant (100) for implantation into apatient's spine in-between first and second adjacent or neighboring vertebrae.The implant may include one or more of the following features : (i) inner(110)and outer (115) members coupled by a radiographically imageable expansionring (130), (ii) detachable endplates (120,125) coupled to the implant via apolygonal press-fit coupling interface that accommodate a range of lordoticendplates to be applied to the implant using any surgical approach, (iii) aninterference pre-loaded set screw (160) for selectively locking the height oftheconstruct, (iv) a radiographically imageable marker (180) for determining theexpansion of the implant, and (v) an asymmetric thread coupling (133,190)betweenthe expansion ring and the inner member.
