Anatomical terms of bone

Gerdy's tubercle is a lateral tubercle of the tibia, located where the iliotibial tract inserts. It was named after French surgeon Pierre Nicolas Gerdy (1797–1856).

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.[1]

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.[2]

It has been used as a source for bone grafts.[3]

The peroneal nerve runs near to it.[4]
