Neck of femur fractures (NOFs) are increasingly common and tend to be sustained by the elderly population as a result of low energy falls in the presence of osteoporotic bone. This artery begins immediately behind the inguinal ligament. The flat popliteal surface lies between them. femoral head and surrounding tissue, left, hip arthroplasty: - non-vital bone consistent with fracture. The posterior inferior nutrient artery of the femoral head is not present in all cases. Distally, the linea aspera widens and forms the floor of the popliteal fossa, the medial and lateral borders form the medial and lateral supracondylar lines. 6th ed. - Femoral Neck Angle: - neck extends inferolaterally from head to meet shaft of femur at angle of about 125 deg; - angle varies w/ age, stature, & width of pelvis, being less in … It is the site of attachment for the iliofemoral ligament (the strongest ligament of the hip joint). The ball-and-socket configuration provides stability while allowing a wide range of joint motion. Left hip-joint, opened by removing the floor of the acetabulum from within the pelvis. Femoral vein (Vena femoralis) The femoral vein is a large vessel located deep within the thigh.It is sometimes referred to as the superficial femoral vein in order to distinguish it from the deep femoral vein.This term is, however, misleading and rarely used due to the fact that the vessel is located deep in the thigh. This portion of the vessel, approximately 2 - 3 cm distal from the inguinal ligament, is the safest site for femoral puncture (see Figure 3 above). The distal end of the femur is characterised by the presence of the medial and lateral condyles, which articulate with the tibia and patella to form the knee joint.

On the posterior surface of the femoral shaft, there are roughened ridges of bone, called the linea aspera (Latin for rough line). Fig 3 – Posterior surface of the right femoral shaft. The fovea capitis is located "slightly posterior and inferior to the center of the articular surface of the femoral head (Cerezal)" Furthermore, unlike the head of the femur, the fovea capitis lacks any hyaline cartilage. These fractures can be broadly classified into two main groups: The shaft of the femur descends in a slight medial direction. It is slightly ovoid in shape and is oriented "superior-to-posteroinferior. In orthopedic surgery, the head of the femur is important because it can undergo avascular necrosis and consequent osteochondritis dissecans. The hip is a ball-and-socket joint. It is the largest bone in the body and is the only bone in the upper leg. Anatomy. Try again to score 100%. Avascular necrosis of the femoral head (ANFH) is a degenerative condition which causes the upper ends of the thigh bones (femurs) to break down due to a disrupted blood supply and poor bone repair. It is the site of attachment for many of the muscles in the gluteal region, such as gluteus medius, gluteus minimus and piriformis. The socket (acetabulum) is located in the pelvis. They are more prevalent in women. The upper extremity is composed of the head, neck, greater trochanter and lesser trochanter. The coxofemoral joint is a diarthrodial articulation between the femoral head and acetabulum.

If there is a fracture of the neck of the femur, the blood supply through the ligament becomes crucial. Fractures of the femoral shaft are typically a high energy injury but can occur in the elderly as a result of a low energy fall. Femoral Angle of Torsion: Formed by looking at the relationship between the axis of the femoral head and neck and the femoral condyles. While the cartilage covers the entire head of the femur, the acetabulum cartilage is in the shape of a horseshoe with a depression (fossa) in the center of the socket. The femoral head is removed in total hip replacement surgery. They can often occur as a spiral fracture, which causes leg shortening. This formation allows for three planes movement at the hip joint: abduction and adduction in the frontal plane, flexion, and extension in the sagittal plane and internal and external rotation in the horizontal plane.Distally, the femoral condyles of the femur articulate with the condyles of the tibia, making the tibiofemoral joint. The proximal femoral head articulates with the acetabulum of the pelvis, forming a “ball-and-socket” joint. RadioGraphica.
