Anatomy of the Lower Leg: Tibia, Fibula & Interosseous Membrane

Tibia:

- Medially located

- articulates with the femur at the knee joint

- articulates with the talus at the ankle joint

- weight-bearing bone of the leg

Fibula:

- Laterally located

- articulates with the tibia at the proximal and distal ends

- provides attachment for muscles

- not weight-bearing

Interosseous membrane:

- connects the tibia and fibula

- reinforces the leg and prevents it from buckling
