Tibia and Fibula

tibia

larger and stronger than the fibula, located more medially and superficially, the proximal end articulates with the femur, distal end articulates with the fibula and talus

fibula

smaller and more laterally located, at the proximal end articulates with the lateral condyle of the tibia, distally, medial and lateral malleoli form the boxlike socket for the ankle and can be palpated by the skin

condyles

bulging prominence at the proximal end of the tibia, concave upper surfaces articulate with the femur

intercondylar eminence

upward projection of the articular surface between condyles- cruciate ligament attachment of the ACL and PCL

fibular notch

small sooth surface along lateral tibial condyle

gerdy’s tubercle

lateral roughened area of tibia, insertion of IT tract

tibial crest

sharp ridge on anterior surface of tibia

tibial tuberosity

projection onto anteriro surface; insertion of patellar tendon on tibia; osgood-schlatter disease happens here

what is osgood-schlatter disease

pain at the tibial tuberosity due to pulling by the tendon

medial malleolus

rounded downward projection at the distal end of the tibia forms medial surface of the ankle

posterior malleolus

posterior region of articular surface with talus, rarely isolated in fracture but may be the site of injury

what muscle inserts on the IT band

gluteus maximus
