Femur Anatomy

Posterior View of the Femur - Head and Trochanters00:00:06

The video begins by examining the posterior view of the femur, pointing out the head of the femur, which is covered with articular cartilage for articulation with the acetabulum. It then identifies the greater trochanter, lesser trochanter, and the intertrochanteric crest connecting them.

Posterior View of the Femur - Gluteal Tuberosity and Linea Aspera00:00:46

Next, the gluteal tuberosity, where gluteus muscles insert, is shown. Following this, the Linea aspera, an attachment point for some hamstring muscles, is highlighted further down the shaft.

Posterior View of the Femur - Supracondylar Lines and Condyles00:01:01

The lateral and medial supracondylar lines are identified. Moving further down, the medial and lateral condyles are presented, along with the intercondylar fossa, a space between the condyles.

Posterior View of the Femur - Epicondyles and Adductor Tubercle00:01:30

The medial epicondyle and a tubercle above it, called the adductor tubercle, which is an attachment for adductor muscles, are then explained. The lateral epicondyle is also identified.

Anterior View of the Femur - Head, Line, and Patellar Surface00:02:00

The video then transitions to the anterior view of the femur, again showing the head of the femur. The intertrochanteric line, a less prominent crest compared to the posterior side, is identified. Further down, the patellar surface, where the patella (sesamoid bone) sits, is highlighted.

Additional Noteworthy Features - Fovea Capitis and Surgical Neck00:02:41

Finally, two additional features are pointed out: the fovea capitis, a divot where ligaments attach to the acetabulum, and the surgical neck of the femur, an important area often implicated in fractures.
