It consists of a head and neck, and two bony processes – the greater and lesser trochanters. There are also two bony ridges connecting the two trochanters; the . Inside the body of the femur is the medullary cavity, which contains bone marrow. At the ends of the femur are areas of compact bone, which is solid and does not contain marrow. Surrounding the compact bone is spongy bone, which has lots of small cavities dispersed throughout it. The neck and head of the femur contain spongy bone. Anterior surface. The femoral neck ( femur neck or neck of the femur) is a flattened pyramidal process of bone, connecting the femoral head with the femoral shaft, and forming with the latter a wide angle opening medialward.

What supplies the head and neck of femur?

The medial and lateral circumflex femoral arteries anastomose to form a ring around the neck of the femur, from which many small arteries branch off to perfuse the femoral head. Another direct source of blood supply is from the foveal artery, aka the artery of the ligamentum teres.

What is the head of the femur made of?

The femoral head’s surface is smooth. It is coated with cartilage in the fresh state, except over an ovoid depression, the fovea capitis, which is situated a little below and behind the center of the femoral head, and gives attachment to the ligament of head of femur.

What is the femoral head and neck?

The femoral neck (femur neck or neck of the femur) is a flattened pyramidal process of bone, connecting the femoral head with the femoral shaft, and forming with the latter a wide angle opening medialward.

What represents the head of the femur?

The femoral head is the most proximal portion of the femur and is supported by the femoral neck. It articulates with the acetabulum of the pelvis. The femoral head is nearly spherical (two-thirds) but has a medial depression known as the fovea capitis femoris that serves as an attachment point for the ligamentum teres.

What is the neck of the femur?

The neck of the femur is around 130 degrees to the shaft (also anteverted by roughly 10 degrees), with the femoral head sitting within the acetabulum. The femoral head’s blood supply is primarily uni-directiona l, most arriving from the medial femoral circumflex artery* (arising from the deep femoral artery).

What is the femoral head?

How is the femur connected to the pelvis?

The head of the femur, which articulates with the acetabulum of the pelvic bone, comprises two-thirds of a sphere. It has a small groove, or fovea, connected through the round ligament to the sides of the acetabular notch. The head of the femur is connected to the shaft through the neck or collum. The neck is 4–5 cm.
