<p>A bone fixation system includes a bone fixation device, including a first element having a first channel extending therethrough and a second element including a proximal portion sized and shaped to be received within the first channel such that the longitudinal axes of the first and second elements are substantially coaxial and a distal portion including a bone engaging structure, a proximal end of the second element slidably locked within the first channel such that the first and second elements are longitudinally movable relative to one another between a permitted range of motion. The system also includes a driving tool, including an outer sleeve and an inner sleeve slidably received therethrough, a distal end of the outer sleeve configured to engage the proximal end of the first element to prevent relative rotation therebetween, a distal end of the inner sleeve configured to engage the proximal end of the second element.</p> |
