Acetabulum

ACETABULUM OF RIGHT HIP BONE (FEMALE)
The cavity or depression on the lateral surface of the innominate bone (hip bone). This bone is composed of the three bones ilium, ischium, and pubis, and provides the socket into which the head of the femur fits. acetabular (-lăr), adjective See: illustration

acetabulum

The socket in the side of the bony pelvis into which the spherical head of the thigh bone (FEMUR) fits. The word is derived from the Latin acetum , vinegar and abulum , the diminutive of abrum , a container. The acetabulum was thought to resemble a small vinegar cup.

acetabulum

one of two cup-shaped sockets in the PELVIC GIRDLE articulating with the ball of the FEMUR.

Acetabulum

The large cup-shaped cavity at the junction of pelvis and femur or thigh bone.

acetabulum

(from the Latin for a vinegar-cup) the cup-shaped cavity on each side of the pelvis into which the head of the femur fits, forming the 'ball-and-socket' of the hip joint. Figure 1.

It is characterized by early pathologic contact during hip joint motion between skeletal prominences of the acetabulum and the femur that limits the physiologic range of motion of the hip-typically flexion and internal rotation.
With this, the femur head was replaced in acetabulum and then sutured.
Also the predicted contact pressure distribution from the centre of the contact to edge of acetabulum was compared for three-dimensional, anatomic and two and three dimensional axisymmetric finite element models as shown in Figure 4.
Ganz and colleagues (3) summarized the mechanism of FAI, in which morphologic abnormalities of the acetabulum and proximal femur lead to anterosuperior soft tissue damage and continued bony contact.
