Hip Replacement Surgery-The Normal Hip,facts

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) January 29, 2008 -- The "Normal" Hip





The hip is a ball-and-socket joint comprised of the following structures:


Head of the femur


Acetabulum of the pelvis


Ligaments of the hip joint

The head of the femur or "ball" of the hip joint articulates or moves within the cup-like "socket" called the acetabulum of the pelvic bone. Together, these structures are referred to as a "ball and socket" joint. The femoral head and acetabulum are covered by a specialized surface called articular cartilage. This allows smooth and painless motion of the hip joint.


Several strong ligaments help hold the head of the femur within the acetabulum. They are named according to their attachments:


The iliofemoral ligament attaches the front of the ilium (pelvic bone) to the femur. It is fan-shaped, resembling an inverted Y and is sometimes referred to as the Y ligament of Bigalow.


The pubofemoral ligament attaches from an area on the front region of the pelvis called the pubis and connects to the femur.

The ishchiofemoral ligament attaches to a bony area on the rear aspect of the pelvis (where the hamstrings attach) and then connects to the femur bone.


The articular capsule, which is very dense and strong, encompasses the entire acetabulum.
