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 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. It creates an attachment point for the ligamentum patellae, or patellar ligament. Other tubercles of the tibia include the medial intercondylar tubercle ...
Both tubercle and tuberosity refer to a projection or bump with a roughened surface, with a "tubercle" generally smaller than a "tuberosity". These terms are derived from tuber (Latin: swelling)., [8] as is also protuberance, which occasionally is synonymous with "tuberosity".
In the human skeleton, a tubercle or tuberosity is a protrusion that serves as an attachment for skeletal muscles. The muscles attach by tendons, where the enthesis is the connective tissue between the tendon and bone. [4] For example, the tibial tuberosity creates an attachment point for the ligamentum patellae, or patellar ligament.
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 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 upper part of the patellar tendon attaches on the lower part of the knee cap, and the lower part of the patella tendon attaches to the tibial tubercle on the front of the tibia. Above the knee cap, the quadriceps muscle via the quadriceps tendon attaches to the top of the knee cap. This structure allows the knee to flex and extend, allowing ...
Gerdy's tubercle is a lateral tubercle of the tibia, located where the iliotibial tract inserts. It was named after French surgeon Pierre Nicolas Gerdy (1797–1856).. Gerdy's tubercle is a smooth facet on the lateral aspect of the upper part of the tibia, just below the knee joint and adjacent to the proximal tibio-fibular joint, where the iliotibial tract runs down the outside part of the thigh.
