Tibia Flashcards
Medial Condyle
The medial part of the tibial plateau. Its femoral articulartion is oval with the long axis orientated anteroposterally. Its lateral edge is straight.
Lateral Condyle
The lateral part of the tibial plateau. Its femoral articulation is smaller and rounder than the medial condyle.
Intercondylar Eminence
This is the raised area on the proximal tibial surface between articular faucets.
Superior Fibular Articular Facet
Located on the postoinferior edge of the lateral condyle.
Medial Surface
This part of the shaft forms the medial edge of the shin of the lower edge. This subcutaneous, anteromedially facing surface is the widest tibial shaft surface.
Lateral Surface
This lies opposite the the fibula. It’s the most concave of the three tibial surfaces.
Posterior Surface
This runs along the entire length of the shaft. The board, flat portion of the posterior surface closest to the knee is often called the popliteal surface - Although it is still part of the posterior surface. The popliteal line runs across the popliteal surface.
Anterior Crest
This forms the anterior edge of the shin. It is the most prominent of the three crests that give much of the tibial shaft its distinctive triangular outline.
Tibial Tuberosity
This is the rugosa area on the anterior surface of the proximal tibia. Superior part is the widest.
Nutrient Foramen
Located inferolaterally to the popliteal line. A large foramen that exits the bone proximally.
Medial Malleolus
The projection in the medial side of the distal tibia that forms the subcutaneous medial knob on the ankle. Its lateral surface articulates the talar body.
Grooves for the Flexor Hallucis Longus
A shallow groove found on the distalmost portion of the posterior tibia. Is less pronounced than the posterior groove.
