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 ...
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 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 sphere. It has a small groove, or fovea, connected through the round ligament to the sides of the acetabular notch.
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 ...
It is not that important as a ligament but can often be vitally important as a conduit of a small artery to the head of the femur, that is, the foveal artery. [28] This artery is not present in everyone but can become the only blood supply to the bone in the head of the femur when the neck of the femur is fractured or disrupted by injury in ...
The iliofemoral ligament is a thick and very tough triangular capsular ligament of the hip joint situated anterior to this joint. It attaches superiorly at the inferior portion of the anterior inferior iliac spine and adjacent portion of the margin of the acetabulum ; it attaches inferiorly at the intertrochanteric line .
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 ...
The transverse acetabular ligament (transverse ligament [1] or Tunstall's ligament [citation needed]) bridges the acetabular notch, creating the a foramen (through which blood vessels and nerves pass into the joint cavity). [2] The ligament is one of the sites of attachment of the ligament of head of femur. [1] [3]: 789
