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 .
The upper or proximal extremity (close to the torso) contains the head, neck, the two trochanters and adjacent structures. [3] The upper extremity is the thinnest femoral extremity, the lower extremity is the thickest femoral extremity. The head of the femur, which articulates with the acetabulum of the pelvic bone, comprises two-thirds of a ...
The head of femur, which articulates with the acetabulum of the pelvic bone, composes 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. long and the diameter is ...
Avascular necrosis is when the femur head loses blood supply, which can lead to the death of bone tissue. ... A femoral hernia develops when inner tissue protrudes from a hole in the thigh called ...
The ligament of the head of the femur (round ligament of the femur, foveal ligament, or Fillmore's ligament) is a weak [1] ligament located in the hip joint. It is triangular in shape and somewhat flattened.
Degree of bulging of the femoral head-neck junction: In normal conditions there is a symmetric concave contour at the junction of the femoral head and neck. Loss of this concavity or bone bulging may lead to cam type impingement. The degree of this deformity can be measured by the alpha angle.
This is what holds the head of the femur securely in the acetabulum. [2] The well-fitting surfaces of the femoral head and acetabulum, which face each other, are lined with a layer of slippery tissue called articular cartilage, which is lubricated by a thin film of synovial fluid. Friction inside a normal hip is less than one-tenth that of ice ...
A femoral head ostectomy is a surgical operation to remove the head and neck from the femur. It is performed to alleviate pain, and is a salvage procedure, reserved ...
