The shin bone is one of the two tubular bones of the lower leg bones. It is located on the medial side of the leg. The fibula is laterally adjacent. It is the second longest bone after the femur and can be divided into three parts: the corpus tibiae (tibia shaft), the extremity proximalis (tibia head) and the extremity malleolaris.

===Tibiaschaft===
+
===Tibia shaft===
der Tibiaschaft stellt den längsten Anteil des Knochens dar. Er hat einen dreieckigen Querschnitt und weist somit drei Kanten und auch drei Flächen auf. Die stark ausgeprägte vordere Kante heißt Margo anterior. Diese beginnt am proximalen Ende des Tibiakopfes und Richtung Extremitas malleolaris flacht sie deutlich ab. Durch diese Kante werden die Außenfläche (Facies lateralis) und die Innenfläche (Facies medialis) voneinander getrennt. Zwischen der Rückseite (Facies posterior) und der Außenfläche befindet sich die Margo interosseus. Die letzte Kante ist die Innenkante (Margo medialis). Diese stellt den Übergang von der Innenfläche zur Rückseite dar. An der Rückfläche ist oben eine leicht raue Linie zu erkennen, die Linea musculi solei.
+
The tibia shaft represents the longest part of the bone. It has a triangular cross-section and thus has three edges and also three surfaces. The most pronounced anterior edge is called Margo anterior. It begins at the proximal end of the head of the tibia and flattens significantly in the direction of the extremity malleolaris. This edge separates the outer surface (facies lateralis) from the inner surface (facies medialis). Between the back (Facies posterior) and the outer surface is the margo interosseus. The last edge is the inner edge (margo medialis). This represents the transition from the inner surface to the back. At the top of the back surface a slightly rough line can be seen, the Linea musculi solei.
  
===Tibiakopf===
+
===Tibia head===
Beim Tibiakopf (Extremitas proximalis oder Caput tibiae) handelt es sich um die proximale Epiphyse. Diese ist verbreitert, so entsteht der deutlich erkennbare Tibiakopf mit seiner massiven Knochenstruktur. Aufgebaut ist dieser aus zwei großen Knochenteilen, dem Condylus medialis und dem Condylus lateralis. Zusammen bilden diese beiden Teile das Tibiaplateau. Dort artikuliert die Tibia über die Gelenkfläche (Facies articularis superior) mit dem Femur. Die Gelenkfläche weist in der Mitte einen knöchernen Hügel (Eminentia intercondylaris) auf, dieser trennt die Gelenkfläche in zwei Teile. Der distale Übergang des Tibiakopfes zum Tibiaschaft ist durch eine raue Erhebung, das Tuberositas tibiae, gekennzeichnet.
+
The head of the tibia (proximal extremities or caput tibiae) is the proximal epiphysis. It is widened, thus creating the clearly visible tibial head with its massive bone structure. It is made up of two large bone parts, the medial condyle and the lateral condyle. Together these two parts form the tibial plateau. There the tibia articulates with the femur via the articular surface (Facies articularis superior). The articular surface has a bony hill (Eminentia intercondylaris) in the middle, which divides the articular surface into two parts. The distal transition from the head of the tibia to the tibia shaft is characterized by a rough elevation, the tibial tuberosity.
  
 
===Extremitas malleolaris===
 
===Extremitas malleolaris===
Das Extremitas malleolaris ist das distale Ende der Tibia. An seiner medialen Seite befindet sich eine knöcherne Verlängerung. Diese stellt den Innenknöchel (Malleolus medialis) dar. Das distale Tibiaende ist im Allgemeinen aber schmaler als der Tibiakopf. Es artikuliert mit dem Talus über eine konkave Genlenkfläche, die Facies articularis malleoli medialis. Die Sulcus malleolaris stellt eine längliche Vertiefung an der Hinterseite des Malleolus madialis dar. Über die Incisura fibularis wird die Verbindung zur Fibula ermöglicht.
+
The extremity malleolaris is the distal end of the tibia. On its medial side there is a bony extension. This represents the inner ankle (malleolus medialis). The distal end of the tibia is generally narrower than the head of the tibia. It articulates with the talus via a concave joint surface, the facies articularis malleoli medialis. The sulcus malleolaris represents an elongated depression at the back of the malleolus madialis. The incisura fibularis provides the connection to the fibula.
  
==Funktion==

==Function==
Die Hauptfunktion des Schienbeines liegt darin, den Oberschenkeln bzw. das Knie mit dem Fuß zu verbinden. Des Weiteren hat das Schienbein eine große Funktion als Tragpfeiler des Beines. Es trägt den Großteil des menschliches Gewichtes und hat somit Anteil am Stand sowie Gang des Menschen.  
+
The main function of the shinbone is to connect the thigh or knee to the foot. Furthermore, the shin bone has a major function as a supporting pillar of the leg. It carries most of the human weight and thus contributes to the human stance and gait.

==Development==
Der Tibiaschaft beginnt bereits in der siebten Embryonalwoche zu verknöchern. Die Verknöcherungen des proximalen und distalen Endes finden erst deutlich später zwischen dem 10. Fetalmonat und dem ersten Lebensjahr statt. Das vollständige Schließen der Epiphysen erfolgt erst zwischen dem siebzehnten und dem zwanzigsten Lebensjahr.

The tibia shaft begins to ossify in the seventh week of embryonic development. The ossifications of the proximal and distal ends do not occur until much later, between the 10th fetal month and the first year of life. Complete closure of the epiphyses does not occur until between the seventeenth and twentieth year of life.

The shin bone (lat. Tibia) represents one of the two lower leg bones. In contrast to the fibula, it has a connection to the thigh bone and is considerably stronger.


Anatomy

View of the tibia

View of the tibia

The shin bone is one of the two tubular bones of the lower leg bones. It is located on the medial side of the leg. The fibula is laterally adjacent. It is the second longest bone after the femur and can be divided into three parts: the corpus tibiae (tibia shaft), the extremity proximalis (tibia head) and the extremity malleolaris.

Tibia shaft

The tibia shaft represents the longest part of the bone. It has a triangular cross-section and thus has three edges and also three surfaces. The most pronounced anterior edge is called Margo anterior. It begins at the proximal end of the head of the tibia and flattens significantly in the direction of the extremity malleolaris. This edge separates the outer surface (facies lateralis) from the inner surface (facies medialis). Between the back (Facies posterior) and the outer surface is the margo interosseus. The last edge is the inner edge (margo medialis). This represents the transition from the inner surface to the back. At the top of the back surface a slightly rough line can be seen, the Linea musculi solei.

Tibia head

The head of the tibia (proximal extremities or caput tibiae) is the proximal epiphysis. It is widened, thus creating the clearly visible tibial head with its massive bone structure. It is made up of two large bone parts, the medial condyle and the lateral condyle. Together these two parts form the tibial plateau. There the tibia articulates with the femur via the articular surface (Facies articularis superior). The articular surface has a bony hill (Eminentia intercondylaris) in the middle, which divides the articular surface into two parts. The distal transition from the head of the tibia to the tibia shaft is characterized by a rough elevation, the tibial tuberosity.

Extremitas malleolaris

The extremity malleolaris is the distal end of the tibia. On its medial side there is a bony extension. This represents the inner ankle (malleolus medialis). The distal end of the tibia is generally narrower than the head of the tibia. It articulates with the talus via a concave joint surface, the facies articularis malleoli medialis. The sulcus malleolaris represents an elongated depression at the back of the malleolus madialis. The incisura fibularis provides the connection to the fibula.

Function

The main function of the shinbone is to connect the thigh or knee to the foot. Furthermore, the shin bone has a major function as a supporting pillar of the leg. It carries most of the human weight and thus contributes to the human stance and gait.

Development

The tibia shaft begins to ossify in the seventh week of embryonic development. The ossifications of the proximal and distal ends do not occur until much later, between the 10th fetal month and the first year of life. Complete closure of the epiphyses does not occur until between the seventeenth and twentieth year of life.
