Abstract
An adjustable bone fusion implant includes a first plate having an interior face with a plurality of spaced apart first support members projecting therefrom. Each support member has a plurality of teeth projecting therefrom. A second plate has an interior face with a plurality of spaced apart second support members projecting therefrom. Each second support member has at least one tooth projecting therefrom. At least a portion of the plurality of teeth of each first support member mechanically engages with the at least one tooth of a corresponding second support member so that the first plate and the second plate can be selectively separated while forming a compartment therebetween. A reinforcing member is disposed between the first plate and the second plate such that the application of a compressive force between the first plate and the second plate applies compression on the reinforcing member.
