Abstract

An orthopedic fusion plate device has a rigid perimetral frame which embraces a pair of plates retained within the frame by a tongue and groove mechanism so that the plates can move in only a single dimension, toward and away from another. The device is intended to mitigate the effects of bone graft resorption and settling through either active or passive mechanisms.
