The three surfaces of the fibula are associated with the three muscular compartments (lateral, posterior, and anterior) of the leg.
Muscles of the thigh are arranged in three compartments separated by intermuscular septa (Fig. 6.57).
The anterior compartment of the thigh contains the sartorius and the four large quadriceps femoris muscles (rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius). All are innervated by the femoral nerve.
