Sentences with word «acetabulum»

In 1966, Henricson, Norberg and Olsson refined the definition of CHD describing it as: «A varying degree of laxity of the hip joint permitting subluxation during early life, giving rise to varying degrees of shallow acetabulum and flattening of the femoral head, finally inevitably leading to osteoarthritis.»

In young dogs, hip dysplasia usually is caused by conformational abnormalities that cause a «poor fit» between the head of the femur and the pelvic acetabulum, which in turn causes laxity of the hip joint.

Hip Dysplasia advanced beyond the point where a Total Hip Replacement is not possible due to extensive bone being worn away along with acetabulum.

Teleocrater (meaning «completed basin», in reference to its closed acetabulum) is a genus of avemetatarsalian archosaur from the Middle Triassic Manda Formation of Tanzania.

In affected dogs, there is laxity present between the femoral head and acetabulum resulting in incongruency of the joint.

The femoral head and acetabulum then become injured and their bony structure changes.

The procedure involves a surgical breaking of the pelvic bones and a realignment of the femoral head and acetabulum restoring the coxofemoral weight - bearing surface area and correcting femoral head subluxation.

The socket or acetabulum loses its depth and becomes shallow as the bone remodels.

This surgery entails cutting free the socket or acetabulum at three points (A, B&C) and rotating it so that the pressure of the femoral head is directly into the cup and not pressing on it's upper edge.

The modular prosthetic hip replacement system used today has three components, a femoral stem, a femoral head, and the artificial acetabulum.

Canine Hip Dysplasia (CHD) is the dislocation of the hip joint; it occurs when the head of the femur (thighbone) does not properly fit into a too shallow acetabulum, the cup - socket at the base of the hipbone.

Hip dislocation is the common term for the separation of the femoral head from the pelvic acetabulum.

Within the acetabulum is a cartilage structure called the labrum which deepens the «socket» and increases the surface area and strength of the hip.

The «socket» is the acetabulum which is one part of the pelvic bone.

This is a condition in which there is a small extra «bump» of bone on the top of your femur (called a «cam» lesion) or on your acetabulum (called a «pincer» lesion) that causes pain when your hip moves.

What happens when the femurol head isplaced well in the acetabulum?

This puts the femur head into the perfect position of the acetabulum (hip socket) for the hip cartilage to harden properly.

This position allows for the very best fit of thefemural head (hip ball) in the acetabulum (hip socket).

With repeated pushing the femoral headand neck against the acetabulum in an unphysiological way, theintegrity of the acetabulum edge is compromised.

This finding is usually caused by a dislocated femoral head which is situated posterior to the acetabulum, instead of in the acetabular fossa.

When an infant's legs are flexed and straddled, the instinctive position that his little body assumes when picked up, the head of his femur (bone of the thigh) fills out the hip socket (acetabulum).

There will be less resistance in the ball - and - socket joint since the femoral head will not be placed in an angled position in the acetabulum as the squat progresses.

The hip socket (acetabulum) isn't located in exactly the same place on everyone's pelvic girdle.

The long bone in the leg, the femur, articulates with the pelvis and thus with the spine through the acetabulum.

coxae), is the joint between the femur and acetabulum of the pelvis and its primary function is to support the weight of the body in both static (e.g. standing) and dynamic (e.g. walking or running) postures.

The femur sits in the acetabulum, which is part of the pelvis.

Surrounding the acetabulum is additional cartilage called the labrum, which forms a lip around the cup shaped bone to provide additional stability in the joint.

The top of the femur (called the femoral head) neatly fits into the pelvic socket (acetabulum), and is held in place by ligaments.

The acetabulum is then rotated to provide better coverage.

In other words, the instability created by weak supportive ligaments keeps the body from being able to manufacture a deep, smooth hip socket for the ball to fit snuggly into, resulting in the flattening of the acetabulum (hip socket) and a squaring of the femoral head (the ball).

Both the ball (head of the femur) and socket (acetabulum) of the hip joint are replaced with prosthetic implants.

This procedure eliminates the bone - to - bone contact of the acetabulum or socket with the femur which can cause much pain, especially in arthritic joints.

Fractures of the acetabulum cause major pain and surgery may not be an option.

The socket is the acetabulum, a scooped out area on the pelvic structure.

Dysplastic dogs have shallow acetabulums — the head of the femur will not rest in the hip socket and instead slides around against the surface of the shallow hip socket.

The Femoral Head fits into the acetabulum and allows it to move freely.

These two bones should fit perfectly together, supported by a strong ligament which attaches the femoral head directly to the acetabulum.

In a healthy dog, the hip socket (acetabulum) is nicely rounded and deep enough to accommodate the femoral head so that the hip's ball and socket joint forms correctly.

The Femoral Head is the ball, and the acetabulum is the socket of the joint.

The surgery involves the creation of an artificial ball and socket joint by removing the natural components (head of femur - «ball», and acetabulum of pelvis - «socket») of the hip joint and inserting synthetic replacement parts that result in a smooth, stable, pain - free hip joint (s).

Muscles hold the bone against the hip / The muscle holds the femoral head in place against the acetabulum, the cup that holds the bone.

The femoral heads (ball) are completely out of the acetabulum (socket).

X-rays can be taken by any veterinarian (no special certification required) and then are submitted to the OFA to be evaluated by a radiologist for hip congruity, subluxation, the condition of the acetabulum, and the size, shape, and architecture of the femoral head and femoral neck.

In HD, however, the head of the femur (the ball) fits poorly in the acetabulum (the socket).

The acetabulum (the hip socket) is easily deformed by continual movement of the femoral head.

The joint capsule and ligament gradually get stretched allowing the femoral head to come out of the acetabulum even further.
