Attaches to anterior and medial borders of tibia
Thicker in proximal leg
Continues as extensor retinaculum distally
Extensions from deep surface-anterior and posterior intermuscular septa-attach to anterior and posterior margins of fibula
Intermuscular septa and interosseous membrane divide leg into three fascial compartments: anterior, lateral, and posterior
Muscles in posterior compartment are subdivided into superficial and deep compartments by transverse intermuscular septumJoints
Proximal tibiofibular joint
Plane-type synovial joint
Nonweightbearing
Between head of fibular and lateral condyle of tibia
Fibrous capsule reinforced by anterior and posterior ligaments of the head of the fibula
Distal tibiofibular
Fibrous joint (syndesmosis)
Medial surface of distal fibula articulates with facet on inferior end of tibia
Reinforced by anterior and posterior tibiafibular ligaments and interosseous ligament (extension of interosseous membrane)Muscles
