4Option B: Creating a tension band using the sesamoid bones

Placing the screws for the tension band

If the distal sesamoidean ligaments are being used to create the tension band, the screws are placed at this time.
One cortex screw is inserted using lag technique through the distal aspect of McIII/MtIII into each of the proximal sesamoid bones to stabilize the sesamoid bones and the distal seamoidean ligaments to the back of McIII/MtIII creating the tension band.
(It is important to place the screws in slight flexion so that when the limb is again placed in extension, the distal sesamoidean ligaments come under tension.)
