Pin insertion

The pin is started at a 20 degree angle relative to the axis of the bone to minimize slippage in the trochanteric fossa.

Gently slide the pin down into the trochanteric fossa.

As soon as the pin penetrates the fossa, the pin is redirected to align with the medullary axis of the bone. The pin is directed slightly caudally and medially to avoid the pin engaging the cranial cortex at the level of the proximal metaphysis.
