ORTHOPEDIC COMPRESSION DEVICE

Abstract: an orthopedic compression device comprises an outer shaft portion having a threaded outer distal end and having an inner cannulation extending from an opening in a proximal end towards an inner distal end, the inner cannulation having a proximal region; a head portion, the head portion having a distal end portion with a geometry keyed to the proximal region of the cannulation of the first shaft to allow rotation of the head portion to drive rotation of the outer shaft portion, the head portion including an inner channel; and an inner shaft portion. the inner shaft portion is formed from a superelastic material and has a stop at a proximal end thereof. the stop engages a stop surface formed within the head portion when the inner shaft portion extends through the inner channel. the inner shaft portion is coupled to the outer shaft portion such that the inner shaft portion elongates and is placed into tension upon separation of the head portion and outer shaft portion.
