Abstract
An orthopedic screw assembly including a proximal member positioned at a proximal end of the orthopedic screw assembly, a distal member positioned at a distal end of the orthopedic screw assembly, and an elongate element having a first end and a second end. The elongate element is coupled to the proximal member at the first end and coupled to the distal member at the second end. The elongate element is configured to apply a dynamic compressive force on each of the proximal member and the distal member, thereby coupling the proximal member to the distal member.

An orthopedic screw assembly, comprising:
- a proximal member positioned at a proximal end of the orthopedic screw assembly;
- a distal member positioned at a distal end of the orthopedic screw assembly;
- and
- an elongate element having a first end and a second end, wherein the elongate element is coupled to the proximal member at the first end and coupled to the distal member at the second end,
- wherein the elongate element is configured to apply a dynamic compressive force on each of the proximal member and the distal member, thereby coupling the proximal member to the distal member.

A method of bone fixation, comprising:
- providing a proximal member and a distal member and coupling the proximal member to the distal member;
- providing an elongate member comprising a responsive zone of a shape memory material;
- inserting the elongate member into the proximal member and into the distal member to form a bone fixation assembly;
- inserting a guide wire through bone fragments;
- inserting the guide wire through the bone fixation assembly;
- and
- coupling the bone fixation assembly to bone fragments so that the responsive zone is positioned adjacent a fracture site in the bone fragments,
- wherein the responsive zone is adapted to apply a desired compressive force to the bone fragments when coupled thereto.
