Anatomy
A thin, fibrous sheet attaching between the interosseous crests of the tibia and fibula.
The fibres pass downwards in criss-cross directions. Its upper margin does not quite reach the proximal tibiofibular joint, and there is a hole in its distal end. These holes are for passage of vessels in the lower limbs.
Functions
Connects the tibia and fibula and holds them together. It also separates the muscles of the posterior and anterior compartments and is an attachment point for many of these muscles.
