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. The ligament is implanted by its apex into the antero superior part of the fovea capitis femoris and its base is attached by two bands ...
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.
Muscle or ligament injuries can be contracted during heavy physical activity —however, it is important not to miss a slipped upper femoral epiphysis. Avascular necrosis of the femoral head (Legg-Calvé-Perthes disease) typically occurs in children aged 4–8, and is also more common in boys. There may be an effusion on ultrasound, similar to ...
Hip fracture. 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]
Frequency. 1/25,000 in boys and 1/100,000 in girls. Legg–Calvé–Perthes disease ( LCPD) is a childhood hip disorder initiated by a disruption of blood flow to the head of the femur. Due to the lack of blood flow, the bone dies ( osteonecrosis or avascular necrosis) and stops growing. Over time, healing occurs by new blood vessels ...
The third type of FAI is a combination of the first two deformities. When either abnormality is present, it changes the position that the femoral head occupies in the hip socket. The increased stresses that the femur and or acetabulum experience may lead to a fracture of the acetabular rim or a detachment of the overstressed labrum.
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 thickest region of the articular cartilage is at the centre of the ...
X-ray of Femoral Osteotomy hardware to correct femoral rotation caused by hip dysplasia. X-ray of the right hip in female patient in early thirties. Two main types of osteotomies are used in the correction of hip dysplasias and deformities to improve alignment/interaction of acetabulum – (socket) – and femoral head – (ball), innominate osteotomies and femoral osteotomies.
