Inserted guide wires enlarge

Cannulated or non-cannulated screws can be used according to the surgeon’s preference. We illustrate the use of 3.5 mm cannulated screws. Since interfragmentary compression is desired, use proper lag screw technique. Screw threads should not block fracture compression.

Guide wire insertion
At least two screws should be inserted to fix the fracture. Therefore, insert guide wires at the foreseen cannulated screw positions. Check the position of the guide wires by image intensification.

Note: beware the axillary nerve and the bicipital tendon.

Cannulated screw insertion

Insert 3.5 mm cannulated screws of correct length over the guide wires. The screw must not perforate the articular cartilage. Use washers only in osteoporotic bone.
