Lots of 2-joint muscles in lower limb (provide support) Kp221 lecture topic 33: transfer most of the weight from femur to foot (cid:858)hat(cid:859) seg(cid:373)e(cid:374)t = head, tru(cid:374)k 70% of body (cid:373)ass, medial and lateral condyles articulate with femoral condyles. Intercondylar eminence separates medial and lateral condyles: posterior aspect of lateral condyle articulates with fibula, shaft is triangular and has tibial tuberosity on anterior surface. Interosseous border faces laterally towards fibular interosseous border: distal end expands to form medial malleolus, lateral malleolus (fibula) extends lower than medial malleolus, easier to invert ankle than to evert it. Invert = typical sprained ankle: evert = fracture (ex. motor vehicle accident, hit from behind) Joints: tibiofibular joint, proximal attachment of tibia and fibula (interosseous membrane runs throughout most of the length of bones, tibiofibular syndesmosis, non-synovial joint at distal end (special ligaments, ex.
