Anatomy
The shaft is connected to that of tibia along its length by an interossous membrane, separating anterior and posterior muscles. The membrane is 1 of 3 articulations between tibia and fibula, along with the proximal tibiofibular joint above and the tibiofibular syndesmosis below.
Clinical
Fracture of tibia usually associated with fracture fibula, as interosseous membrane transmits the force. Fibula is not weight-bearing; with isolated fracture, can still walk. Proportionally the slenderest long bone.
