On its proximal end, the rounded head of the femur articulates with the coxal bone, within the acetabulum. |
|
The pelvic component of the hip joint is called the acetabulum, which has contributions from the ischium, ilium and pubis. |
|
The radial grooves and ridges are visible on the infundibulum and the orifice that opens into the acetabulum is visible. |
|
In this operation both the head of the femur and the acetabulum are replaced. |
|
The hip is a ball-and-socket joint where the thigh bone's femoral head fits into the acetabulum of the pelvis. |
|
An x-ray is taken postoperatively to verify that the acetabulum is corrected and the acetabular fragment is secured with cortical screws. |
|
The acetabulum contains the socket portion of the hip joint and must be reshaped to restore its original center. |
|
The musculature of the wall of the infundibulum is similar to that of the acetabulum. |
|
The cuticle is shed from the infundibulum and the acetabulum simultaneously as a single unit. |
|
Treatment aims to contain the femoral head in the acetabulum to reduce the risks of future osteoarthritis. |
|
The hip is a synovial, ball-and-socket joint formed by the head of the femur and acetabulum of the coxal bone. |
|
The porous acetabulum may be secured with screws to allow cancellous bone ingrowth. |
|
Immediately anterior to this buttress, a small, deep concavity is located along the anterodorsal margin of the acetabulum. |
|
There are moderate depressions in the lateral surfaces of the ilia posterior and dorsal to the acetabulum. |
|
Ultrasonography provides visualization of the cartilage, hip stability and features of the acetabulum. |
|
The chitinous cuticle that covers the infundibulum extends into and covers the inner surface of the acetabulum. |
|
The articulation between the head of the femur and the acetabulum form the hip joint. |
|
Some surgeons impact the shell implant into the acetabulum, and other surgeons prefer to fixate the implant with screws. |
|
Gradually the blood vessels to the hip cut off nourishment to the head of the femur where it fits into the acetabulum. |
|
The hip is a true ball-and-socket joint, where the ball of the femur is securely cradled in a deep socket of pelvic bone called the acetabulum. |
|
|
The acetabulum is a hemispherical socket formed in the os coxae of a newborn where the ilium, ischium, and pubis bones come together. |
|
Easily visualizing the acetabulum, the surgeon places retractors, avoiding sciatic nerve injury. |
|
The extension of the outer connective tissue capsule that encloses the infundibulum is thinner than the portion covering the acetabulum. |
|
The hip joint is a ball-and-socket joint because the spherical head of the femur moves inside the cup-shaped acetabulum. |
|
For example, fractures of the acetabulum and pubic ramus or stress fractures may present with signs and symptoms similar to those of a hip fracture. |
|
Regardless of the chosen system, a primary THA replaces the proximal femur, including the femoral head, and resurfaces the acetabulum, creating a new ball-and-socket joint. |
|
A cotyloid bone, formed in the cartilage in the bottom of the acetabulum, is usually found. |
|
The flanges are fixed onto the ilium and ischium to build a bridge over the acetabulum, allowing for massive bone grafts to be used. |
|
Another contrast, in terms of function, is seen in the shallowness of the glenoid fossa, as contrasted with the depth of the acetabulum. |
|
All three serve as attachments for leg muscles and contribute to the acetabulum, which forms the articulation for the femur. |
|
The Bipolar head is indicated in cases of fractures of the femoral neck where the acetabulum is still in a healthy condition. |
|
The oversizing at the cup's equator ensures an optimal primary press-fit fixation of the implant in the acetabulum. |
|
A straight cut is made to a point cranial of the acetabulum to the ischiatic lymph node at the dorsal edge of the rump. |
|
Hip disease due to involvement of the femoral head or acetabulum is common. |
|
The patient showed significant osteolysis of the acetabulum with a Paprosky IIIa defect. |
|
Simultaneous contraction of the meridional and radial muscles probably flattens the infundibular surface and bends the rim of the infundibulum towards the acetabulum. |
|
The acetabulum is also the socket for the head of the femur. |
|
The acetabular labrum is a triangular fibrocartilage that is attached at its base to the rim of articular cartilage surrounding the perimeter of the acetabulum. |
|
Thus, to describe the mechanism of attachment, we must describe both how pressure can be reduced in the acetabulum and how a seal can be formed with the surface of attachment. |
|
The muscle volume has to go somewhere, so the circumference of the cup-shaped acetabulum has to increase, increasing the volume of the acetabular chamber. |
|
|
Using scanning electron microscopy, the parasite's body shows transverse ridging and tegumentary papillae around the oral aperture, genital pore and acetabulum. |
|
The pelvic girdle consists originally of three bones, which become fused in early adulthood and each of which contributes a part of the acetabulum, the deep cavity into which the head of the thighbone, or femur, is fitted. |
|
Alternatively, VDRO or double, triple, or shelf osteotomy of the acetabulum can be used to keep the head more congruently reduced. |
|
The elliptical design and the slight polar flattening permit a secure placement of the cup into the acetabulum. The flattened pole prevents a force transmission to the thinnest point of the acetabulum. |
|
Drawing top: the femora head which represents the top of the femur has the shape of a sphere which comes to be articulated in a concave cavity: the acetabulum. |
|
The ability to take reliable and reproducible measurements of the inclination and anteversion of the acetabulum using eOS was confirmed in a recently completed study. |
|
When the cartilage is being worn away, the femoral head and the acetabulum will rub one another. |
|
The initial target was immediately inferior to the anterior inferior iliac spine in the upper third of the acetabulum. |
|
A contraindication is given in case the acetabulum is diseased or injured. |
|
The Leg is removed by a cut parallel to the Forequarter removal line at right angles at a measured distance from the hip joint to clear the acetabulum. |
|
Three of these patients had bone marrow edema at the acetabulum, and the other three at the lateral aspects of the femoral heads and the tuberculum majus. |
|
Sizing the acetabulum on an orthogonal lateral view of the acetabulum will provide additional insight on sizing, particularly in the nonhemispheric acetabulae. |
|
There was also an avulsion fracture of the anterosuperior acetabulum and a severely comminuted fracture of the right femoral neck with cephalad displacement. |
