Femur

Intertrochanteric line

A variable, fairly vertical, roughened line that passes between the lesser and greater trochanters on the anterior surface of the base of the neck of the femur

Adductor tubercle

A variable, raised tubercle on the medial supracondylar line just superior to the medial epicondyle

Neck

Connects the femoral head with the shaft and the greater trochanter

Nutrient foramen

Located about midshaft level on the posterior surface of the bone, adjacent to or on the linea aspera

Lesser trochanter

The blunt, prominent tubercle on the posterior femoral surface just inferior to the point where the neck joins the shaft

Lateral epicondyle

The convexity on the lateral side of the lateral condyle

Medial epicondyle

The convexity on the medial side of the medial condyle

Intertrochanteric crest

The elevated line on the posterior surface of the proximal femur between the greater and lesser trochanters

Lateral supracondylar ridge

The inferior (distal), lateral extension of the linea aspera

Medial supracondylar ridge

The inferior, medial extension of the linea aspera, marking the distal, medial corner of the shaft

Medial condyle

The large, articular knob on the medial side of the distal femur

Greater trochanter

The large, blunt, nonarticular prominence on the lateral, proximal part of the femur

Lateral condyle

The large, protruding, articular knob on the lateral side of the distal femur

Shaft

The long section between expanded proximal and distal ends of the bone

Linea aspera

The long, wide, roughened, and elevated ridge that runs along the posterior shaft surface

Intercondylar fossa

The nonarticular, excavated surface between the distal and posterior articular surface of the condyles

Head

The rounded proximal part of the bone that fits into the acetabulum

Fovea capitis

The small, nonarticular depression near the center of the head of the femur

Popliteal surface

The wide, flat, triangular area of the posterior, distal femur

Gluteal line

A long, wide, roughened, posterolaterally placed feature that extends from the base of the greater trochanter to the lateral lip of the linea aspera

Patellar surface

A notched articular area on the anterior surface of the distal femur, over which the patella glides during flexion and extension of the knee
