7.3mm Cannulated Screw

7.3mm Cannulated Screws

Product Overview

The 7.3mm Cannulated screw is a part of Auxein's bone screw system. The screw is available in 16mm, 32mm and full length lengths.

Cannulated screws are used in bone and joint surgery to repair breaks and to secure artificial implants which may be used to replace part or all of a joint. The main advantage of cannulated screws is that they can be inserted over a guide wire or guide pin. The diameter of the guide pin is much smaller than the cannulated screw and can be more accurately placed in operating room. The screw is available with washer. The threaded washer allows use of the 7.3mm cannulated screw in indications requiring a completely recessed screw head.

Benefits

Cannulated shaft accepts 2.8mm diameter guide wires.
Hemispherical Head ensures optimal annular contact with washer and Auxein’s plates when screws are angled.
Low profile head reduces possibility of soft tissue irritation.
Reverse Cutting flutes assist in screw removal.
Choice of thread lengths offers best fit of threads into far bone fragment, for greater interfragmentary compression.
Cancellous thread profile uses deep cutting threads with a large pitch to increase resistance to pullout. The large pitch also accelerates screw insertion and removal.
Self-drilling, self-tapping screw tip facilitates screw insertion by eliminating the need of pre-drilling and tapping in most cases,
