Dynamic Plate With Inserts

Abstract

A spinal plate that is self-adjusting along its longitudinal axis to accommodate subsidence that may occur and aid in loading the bone graft to promote boney fusion while providing rigid fixation. The spinal plate is configured to inhibit loosening or backing out of bone screws.

What is claimed is: 
     
         1 . A bone plate operatively attachable to bone comprising:
 a first segment; and   a second segment, the first and second segments positioned along a longitudinal axis and movable relative to one another; and   a locking mechanism that inhibits relative axial movement of the first and second segments along the longitudinal axis toward one another and any non-axial movement of the first and second segments relative to one another.
