Cannulated Screws 3.5mm, 4mm, 4.5mm, 6.5mm, 7mm, 7.3mm
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 using fluoroscopy in the operating room. In addition, given its small diameter, the guide pin can be reinserted several times if necessary for accurate placement without excessive damage to bone.
