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 ...
Anterior cruciate ligament reconstruction ( ACL reconstruction) is a surgical tissue graft replacement of the anterior cruciate ligament, located in the knee, to restore its function after an injury. [ 1] The torn ligament can either be removed from the knee (most common), or preserved (where the graft is passed inside the preserved ruptured ...
As the lateral portion is twisted like a screw, the two parts together take the form of an inverted Y. [4] [verification needed] Arising from the anterior inferior iliac spine and the rim of the acetabulum, the iliofemoral ligament spreads obliquely downwards and laterally to the intertrochanteric line on the anterior side of the femoral head.
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.
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.
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.
The earliest recorded attempts at hip replacement were carried out in Germany in 1891 by Themistocles Gluck (1853–1942), [104] [105] who used ivory to replace the femoral head (the ball on the femur), attaching it with nickel-plated screws. [106] Subsequently, he used a cement made from plaster of Paris, powdered pumice and glue. [107]
Medial knee injuries (those to the inside of the knee) are the most common type of knee injury. [ 1 ] The medial ligament complex of the knee consists of: [ 2 ] This complex is the major stabilizer of the medial knee. Injuries to the medial side of the knee are most commonly isolated to these ligaments. [ 1 ][ 3 ] A thorough understanding of ...
