The proximal or upper extremity of the tibia is expanded in the transverse plane with a medial and lateral condyle, which are both flattened in the horizontal plane. The medial condyle is the larger of the two and is better supported over the shaft.
Pes anserinus inserts onto the anteromedial (front and inside) surface of the proximal tibia. The muscles are the sartorius , gracilis and semitendinosus sometimes referred to as the guy ropes . The name "goose foot" arises from the three-pronged manner in which the conjoined tendon inserts onto the tibia.
Tibial tuberosity fractures are infrequent fractures, most common in adolescents. In running and jumping movements, extreme contraction of the knee extensors can result in avulsion fractures of the tuberosity apophysis. [3] A cast is all that is required if the fragment is not displaced from its normal position on the tibia. However, if the ...
The medial malleolus is found at the foot end of the tibia. The medial surface of the lower extremity of tibia is prolonged downward to form a strong pyramidal process, flattened from without inward - the medial malleolus. The medial surface of this process is convex and subcutaneous.
The gracilis arises from near the pubic symphysis and is unique among the adductors in that it reaches past the knee to attach on the medial side of the shaft of the tibia, thus acting on two joints. It share its distal insertion with the sartorius and semitendinosus, all three muscles forming the pes anserinus. It is the most medial muscle of ...
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 long, relatively straight main body of a long bone; region of primary ossification. Also known as the shaft. dia-+ physis, "between the growth parts" epiphysis: The end regions of a long bone; regions of secondary ossification. epi-+ physis, "on top of the growth part" physis (epiphyseal plate) Also known as the growth plate.
Medial condyle of tibia. ... The medial condyle is the medial (or inner) portion of the upper extremity of tibia. It is the site of insertion for the semimembranosus ...
