The tibia (/ ˈ t ɪ b i ə /; pl.: tibiae / ˈ t ɪ b i i / or tibias), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects the knee with the ankle.
The tibial tuberosity thus forms the terminal part of the large structure that acts as a lever to extend the knee-joint and prevents the knee from collapsing when the foot strikes the ground. [1] The two ligaments, the patella, and the tibial tuberosity are all superficial, easily palpable structures. [2]
The cnemial crest is a crestlike prominence located at the front side of the head of the tibiotarsus or tibia in the legs of many mammals and reptiles (including birds [1] and other dinosaurs). The main extensor muscle of the thigh is attached to this ridge.
The intercondyloid eminence, intercondylar eminence or tibial spine is a structure of the tibia. It lies between the articular facets of the proximal tibia, but nearer the posterior than the anterior aspect of the bone, surmounted on either side by a prominent tubercle, on to the sides of which the articular facets are prolonged.
The most prominent tubercle of the tibia, a leg bone which is more commonly known as the shinbone or shankbone, is the tibial tuberosity. The tibial tuberosity is located on the tibia's anterior surface, distal to the medial condyle. It creates a bony prominence just below the patella, and can be easily located with the fingers.
The foot's upper bones are fused with the tibia to form the tibiotarsus, while the centralia are absent. [5] [6] The anterior (frontal) side of the dorsal end of the tibiotarsus (at the knee) contains a protruding enlargement called the cnemial crest. [2]
[9] [4] One tibial section attaches to soft tissue, 1 cm distal to the joint line. The other tibial section attaches directly to the tibia, anterior to the posteromedial tibial crest, 6 cm distal to the joint line. [2] [9] This distal attachment is the stronger of the two and makes up the floor of the pes anserine bursa.
The other thumb is placed on the head of the fibula with the index finger on the tibial crest. The ability to move the tibia forward (cranially) with respect to a fixed femur is a positive cranial drawer sign indicative of a rupture (it will look like a drawer being opened). [9]
