Let us examine the structure of the tibia (tibia). It is one of the leg bones and is located medially.
It consists of three parts:
body (corpus tibiae/diaphysis)
proximal epiphysis (epiphysis proximalis)
distal epiphysis (epiphysis distalis)
Three surfaces are also distinguished (best seen in the region of the body of the bone):
posterior surface (facies posterior)
medial surface (facies medialis)
lateral surface (facies lateralis)
The tibia has three borders (which are best seen in the body area):
anterior border (margo anterior)
medial border (margo medialis)
interosseous border (margo interosseus)
There are two condyles on the proximal epiphysis — the medial condyle (condylus medialis)
and the lateral condyle (condylus lateralis).
They have an upper articular surface (facies articularis superior) that is used to connect to the condyles of the femur.
There is an intercondylar eminence (eminentia intercondylaris) between the condyles.
Within this eminence lies a lateral intercondylar tubercle (tuberculum intercondylare laterale)
and a medial intercondylar tubercle (tuberculum intercondylare mediale).
The anterior intercondylar area (area intercondylaris anterior) and the posterior intercondylar area (area intercondylaris posterior) can be distinguished in front of the tubercles. These areas are the attachment sites of the cruciate ligaments.
The lateral condyle has a fibular articular facet (facies articularis fibularis) for articulation with the fibula.
On the anterior border of the body of the tibia is the tibial tuberosity (tuberositas tibiae), to which the quadriceps is attached.
And on the posterior surface of the bone there is the soleal line (linea musculi solei).
On the distal epiphysis we can distinguish the fibular notch (incisura fibularis), which articulates with the fibula.
The medial malleolus (malleolus medialis) descends from the epiphysis.
It has an articular surface (facies articularis malleoli), which below passes into the inferior articular surface (facies articularis inferior) of the tibia. And both of these surfaces are involved in the formation of the ankle joint.
Behind the malleolus lies the malleolar sulcus (sulcus malleolaris).
