The femoral neck (also 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.
The femoral head (femur head or head of the femur) is the highest part of the thigh bone . It is supported by the femoral neck. Structure The head is globular and ...
The femur is the largest and thickest bone in the human body. It is considered the strongest bone by some measures, though other tests suggest the temporal bone may be stronger. On average, the femur length accounts for 26.74% of a person's height, [4] a ratio found in both men and women across most ethnic groups with minimal
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 ...
A hip fracture is a break that occurs in the upper part of the femur (thigh bone), at the femoral neck or (rarely) the femoral head. [2] Symptoms may include pain around the hip, particularly with movement, and shortening of the leg. [2] Usually the person cannot walk. [3] A hip fracture is usually a femoral neck fracture.
The other two borders of the femur are only slightly marked: the lateral border extends from the antero-inferior angle of the greater trochanter to the anterior extremity of the lateral condyle; the medial border from the intertrochanteric line, at a point opposite the lesser trochanter, to the anterior extremity of the medial condyle.
From its femoral attachment some of the fibers are reflected upward along the neck as longitudinal bands, termed retinacula. The capsule is much thicker at the upper and forepart of the joint, where the most resistance is required; behind and below, it is thin and loose. It consists of two sets of fibers, circular and longitudinal.
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.
