Abstract
This disclosure describes exemplary screw and intramedullary devices that are better able to bring bone fragments into close proximity with each other, generate a compressive load, and maintain that compressive load for a prolonged period of time while healing occurs. The devices are made of a shape memory material.
Claims10
A compression screw system, comprising:
- a compression screw made of a shape memory material such that a portion of a shaft of the compression screw is positionable in a bent condition, wherein the compression screw includes a central lumen having an annular shoulder;
- and
- an internal retaining pin insertable into the compression screw and configured for moving the portion from the bent condition to a straightened and stretched condition, wherein the internal retaining pin extends into the central lumen, and the internal retaining pin is seated against the annular shoulder of the central lumen when the portion of the shaft is in the straightened and stretched condition.
