Then you “tent” the skin temporarily to bring the pin to an angle that will allow you to insert it into the fracture site.

Having worked the point of the pin into the fracture site, you tilt the pin back to the original angle (thus reducing the fracture) and drive it into the opposite cortex.

This “buttress pin” technique can also be used to fix sheared off fragments of metaphyseal cancellous bone though the technique is not as necessary  in this region.
