Gerdy's tubercle is a smooth facet on the lateral aspect of the upper part of the tibia, just below the knee joint and adjacent to the proximal tibio-fibular joint, where the iliotibial tract runs down the outside part of the thigh. It is the point of insertion for the Iliotibial band of the lateral thigh.
It is used as a site for the insertion of a periosteal needle by which intramedullary fluids may be infused in neonates. It can be fractured along with the tibial tuberosity.
The peroneal nerve runs near to it.
