7 Features of the proximal FEMUR BONE
1.Head; 2. Fovea Capitis; 3.Neck; 4.Greater Trochanter; 5.Lesser Trochanter; 6.Intertrochanteric line; 7.Intertrochanteric Crest.
The FEMUR is the…
longest and strongest bone in the body
Proximally, the FEMUR articulates with the…
acetabulum to form the hip joint.
As the FEMUR goes from proximal to distal, it courses…
medially. The medial coursing is generally more pronounced in women due to their wider pelvises.
The FOVEA CAPITIS is…
a small central pit on the femur’s head, from which a ligament runs to the acetabulum, helping to secure the femur.
The HEAD of the FEMUR attaches distally to..
the neck of the femur.
Which way does the NECK of the femur angle and why does it do so?
The neck of the femur angles laterally to join the shaft of the femur, because the femur articulates with the lateral aspect of the pelvis rather than the distal aspect.
The weakest part of the FEMUR is…
the neck, which is often the site of fracture when someone gets a “broken hip”.
The GREATER TROCHANTER is located…
at the juncture of the femur’s shaft and neck, proximal to the shaft on the lateral side.
The LESSER TROCHANTER is located…
At the juncture of the femur’s shaft and neck on the medial-posterior side, distal to the greater trochanter and head.
The GREATER TROCHANTER and LESSER TROCHANTER serve as…
sites of attachment for thigh and buttock muscles.
The INTERTROCHANTERIC LINE is located…
on the anterior femur, between the greater and lesser trochanters, which it connects.
The INTERTROCHANTERIC CREST is located…
on the posterior femur, between the greater and lesser trochanters, which it connects.
The GLUTEAL TUBEROSITY is located…
on the lateral side of the posterior shaft of the femur and just distal to the intertrochanteric crest.
The LINEA ASPERA is a …
long vertical ridge on the posterior shaft of the femur, which blends out of the more proximal gluteal tuberosity.
The MEDIAL and LATERAL SUPRACONDYLER LINES…
diverge in their respective directions from the LINEA ASPERA on the distal shaft of the femur.
The MEDIAL and LATERAL CONDYLES are…
wheel like protrusions on the distal end of the femur, which articulate with the tibia’s condyles to form the knee joint.
5 Features of middle FEMUR.
1 .Shaft; 2.Gluteal Tuberosity; ; 3.Linea Aspera; 4.Medial Supracondyler line; 5.Lateral Supracondylar line.
7 Features of distal FEMUR.
1.Medial Condyle; 2.Lateral Condyle; 3.Medial Epicondyle; 4.Lateral Epicondyle; 5.Adductor Tubercle; 6.Patellar Surface; 7.Intercondylar Notch.
The MEDIAL and LATERAL EPICONDYLES…
flank their respective condyles, proximally.
The ADDUCTOR TUBERCLE lies…
on the superior surface of the medial epicondyle.
The PATELLAR SURFACE is …
a smooth surface on the anterior aspect of the femur between the medial and lateral condyle, which articulates with the patella.
The INTERCONDYLAR NOTCH lies…
on the posterior aspect of the femur, between the medial and lateral condyles.
“PATELLA” means…
“small pan”.
