Tibia and Fibula Bones – Anterior View

Tibia Bone Markings:

  1. image descriptionLateral condyle (condylus lateralis) is a lateral expansion of the tibia’s proximal end.

  • A fibrocartilage pad or lateral mensicus covers the condyle’s flattened superior surface so it can smoothly articulate with the lateral condyle of the femur.
  • The iliotibial tract attaches to the front of the condyle and the short head of the biceps femoris attaches to the back.
  1. image descriptionMedial condyle (condylus medialis) is a medial expansion of the tibia’s proximal end.

  • It’s superior surface is covered by the medial condyle of the femus.
  • The posterior of the medial condyle provides attachment for the semimembranosus muscle.
  1. image descriptionIntercondylar eminence (eminentia intercondylaris) is an elevated area between the condyles that contains the bump-like raised medial edges of each condyle.

  • Roughened depressions located anterior and posterior to the eminence are attachment sites for the anterior and posterior cruciate ligaments and the central tips of the medial and lateral menisci.
  1. image descriptionTibial tuberosity (tuberositas tibiae) is a raised, roughened area on the anterior surface of the bone, just inferior to the condyles.

  • This region, which is also called the tuberosity of the tibia, is an attachment point for the patellar ligament (= distal portion of the quadriceps tendon).
  1. image descriptionTibial shaft or body (corpus tibiae) is the long, cylindrical midsection of the bone.

  • It extends from the tuberosity to the medial malleolus and is the most prominent along the upper two-thirds of the bone
  • The deep fascia of the leg attaches here.
  1. image descriptionInterosseous border or margin (margo interosseus tibiae) is the tibia’s sharp-edged lateral margin that provides attachment for the interosseous membrane of the leg.

  • This ligament-like membrane binds the tibia and fibula.
  • It also seperates the leg into posterior and anterior compartments and is an attachment site for some of the leg muscles.
  1. image descriptionMedial malleolus (malleolus medialis) is a prominent downward projection at the distal end of the tibia, on the medial side.

  • It articulated with the talus bone to form the medial portion of the ankle joint.
  • The medial malleolus also serves as the proximal attachment for the deltoid (medial collateral) ligament, which binds the tibia calcaneus and talus bones of the foot.
  1. image descriptionFibular notch (incisura fibularis) is an concavity at the distal end of the tibia, on the lateral side.

  • It articulates with the fibula to form the inferior tibiofibular joint.

Fibula Bone Markings:

  1. image descriptionHead of fibula (caput fibulae) is a small, knob-like extension from the proximal end of the fibula that articulates with the lateral condyle of the tibia.

  • The head is an attachment site for the soleus, bicep femoris (long head), fibularis (peroneus) longus, and extensor digitorum longus muscles as well as the fibular (lateral) collateral ligament.
  1. image descriptionShaft of fibula or body (corpus fibulae) is the elongated midsection bone.

  • The medial malleolus, which extends more inferiorly than the lateral malleolus, articulates with the tibia and the talus bones of the foot to form the lateral portion of the ankle joint.
  • Several ligaments attach the lateral malleoulus to the tibia, talus, and calcaneus bones.
