Study Notes
Tibia Overview
- Main bone of the lower leg, forming the shin
- Expands at proximal and distal ends, articulating at knee and ankle joints respectively
- Second largest bone in the body, playing a key role in weight-bearing
Proximal Tibia
- Widened by medial and lateral condyles, which aid in weight-bearing
- Condyles form a flat surface, known as the tibial plateau
- Articulates with femoral condyles to form the key articulation of the knee joint
- Located between condyles, the intercondylar eminence projects upwards on either side as medial and lateral intercondylar tubercles
- Intercondylar tubercles are the main site of attachment for ligaments and menisci of the knee joint
- Articulates with the intercondylar fossa of the femur
Shaft of Tibia
- Prism-shaped, with three borders and three surfaces: anterior, posterior, and lateral
- Anterior border is palpable subcutaneously down the anterior surface of the leg as a shin
- Proximal aspect of anterior border is marked by the tibial tuberosity, attachment site for the patella ligament
- Posterior surface is marked by the Soleal line, site of origin for part of the soleus muscle
- Soleal line extends inferomedially, eventually blending with the medial border of the tibia
- Usually, a nutrient artery is located proximal to the Soleal line
- Lateral border (Interosseous border) gives attachment to the interosseous membrane that binds the tibia and fibula together
Distal End of Tibia
- Widens to assist with weight-bearing
- Medial malleolus is a bony projection continuing inferiorly on the medial aspect of the tibia
- Articulates with tarsal bones to form part of the ankle joint
- On the posterior surface of the tibia, there is a groove through which the tendon of tibialis posterior passes
- Laterally, there is a fibular notch, where the fibula is bound to the tibia, forming the tibiofibular joint
