Abnormal development of the hip includes the osseous structures, such as the acetabulum and the proximal femur, as well as the labrum, capsule, and other soft tissues. (medscape.com)
Femoroacetabular impingement (FAI) syndrome is a motion-related clinical disorder of the hip involving premature contact between the acetabulum and the proximal femur, which results in particular symptoms, clinical signs and imaging findings. (physio-pedia.com)
This ball and socket joint consists of two basic parts - the acetabulum and the femur. (dpca.org)
The acetabulum forms the socket part of the joint and it is into this socket that the head of the femur rests. (dpca.org)
The separation between the bones is called subluxation, and at its most severe it can become a total dislocation (the head of the femur leaves the acetabulum). (dpca.org)
According to the actual size of the patient's acetabulum and femur, acetabular and femoral prostheses were assembled using Solidworks 2014 (Dassault, France). (hindawi.com)
The primary imaging modality for diagnosing FAI is a plain radiograph of the pelvis, which can be used to measure the alpha angle and the lateral center edge angle used to quantify severity. (openmedicalpublishing.org)
Femoral head and acetabulum1
This poor fit between femoral head and acetabulum is characteristic of dysplastic dogs. (dpca.org)
True acetabulum7
During THA surgery, an obvious superolateral bone defect has been reported to be frequently observed above the surface of the acetabular cup at the level of the true acetabulum, especially in patients with Crowe II or III DDH [ 7 , 8 ]. (hindawi.com)
Here comes to a conclusion that acetabular cups can meet the CC of more than 70% at the true acetabulum, and 60% of Crowe type Ⅱ and type Ⅲ DDH patients can obtain satisfactory CC at the true acetabulum by using a 44-mm cup without additional operation. (researchsquare.com)
When the acetabular cup is placed at the level of the true acetabulum, the bone defect caused by acetabular dysplasia may result in poor cup coverage (CC) in THA 1 , 2 , thus leading to unsatisfactory initial stability and low long-term survival rate 3 - 5 . (researchsquare.com)
In order to achieve adequate CC, several studies 6 - 8 have recommended bone grafting, the medial protrusio technique, and the use of extra-small cups at the true acetabulum to during acetabular reconstruction. (researchsquare.com)
The high hip center (HHC) technique placing the acetabular cup above the true acetabulum during acetabular reconstruction, is suitable for DDH patients, because it can make full use of the bone above the true acetabulum to ensure adequate host bone coverage of the cup 12 , 13 . (researchsquare.com)
Our previous study on morphological features of the true acetabulum in DDH patients shows that the bone stock at the true acetabulum of Crowe type Ⅰ and Crowe type Ⅳ patients was sufficient to support acetabular reconstruction, but for type Ⅱ and type Ⅲ patients, additional surgery may be required for in situ acetabular reconstruction 17 . (researchsquare.com)
In the present study, we firstly evaluated the CC of acetabular cup models with different sizes in patients with Crowe type Ⅱ and type Ⅲ DDH using the HHC technique to reconstruct the acetabulum, then analyzed the CC of host bone in all hips when reconstructing acetabulum at the true acetabulum with 44-mm acetabular cup models.

In case the measured value is beyond the normal range according to reference database, the hips are categorised as borderline, mild or severe dysplastic. (apple.com)
3) Automatically and interactively measure the 3D morphological parameters of the dysplastic acetabulum. (easychair.org)
The automatic parameter measurement function of this software could fast and accurately measure the 3D morphological parameters of the dysplastic acetabulum. (easychair.org)
So, we draw a distribution frequency map of uncovered portion of all 44-mm cups at the true acetabula to illustrate the distribution of bone defects of the acetabulum. (researchsquare.com)
The map shows that 95% of type Ⅱ and type Ⅲ DDH acetabula had bone defects in posterosuperior, and 60% were located outside the force line of the hip joint. (researchsquare.com)
Labrum2
The labral line runs from the labrum to the superior bony rim of the acetabulum or to the transition point from the convexity of the superior bony rim to the concave acetabular roof. (orthofixar.com)
Patients that sustain a small hip labrum tear may find non-surgical treatment measures beneficial for symptom management. (houstonsportsortho.com)
The normal growth of the acetabulum depends on normal epiphyseal growth of the triradiate cartilage and on the three ossification centers located within the acetabular portion of the pubis (os acetabulum), ilium (acetabular epiphysis), and ischium. (medscape.com)
All angles are measured in relation to the "baseline," which is tangent to the lateral border of the ilium. (orthofixar.com)
The acetabular roof line is drawn from the superior bony rim of the acetabulum to the lower edge of the ilium in the acetabular fossa. (orthofixar.com)
Acetabular rim2
Pincer morphology describes "overcoverage" of the femoral head by the acetabulum in which the acetabular rim is extended beyond the typical amount, either in one focal area or more generally across the acetabular rim. (physio-pedia.com)
A dorsal acetabular rim view is used by some surgeons to evaluate the acetabulum before reconstructive surgery. (msdvetmanual.com)
Pelvic4
As your leg moves, the ball of your thighbone (called the femoral head) moves and rotates against the socket portion of your pelvic bone (called the acetabulum). (indiahospitaltour.com)
Surgical treatments include pectineal myotenectomy to reduce pain, triple pelvic osteotomy to prevent subluxation, pubic fusion to prevent subluxation, joint capsule denervation to reduce pain, dorsal acetabulum reinforcement to reduce subluxation, femoral head and neck resection to reduce arthritis, and total hip replacement for optimal restoration of joint and limb functions. (msdvetmanual.com)
ASTM was measured for each hip on pelvic radiographs. (afsu.edu.tr)
Similarly, we measured the angles formed by these lines using the vertical axis of the anterior pelvic plane on the horizontal plane and the horizontal axis on the sagittal plane. (bvsalud.org)
Morphological2
In order to help orthopedists, evaluate the morphological characteristics of the acetabulum of patients with osteoarthritis, a 3-dimensional (3D) acetabular morphologic parameters measurements software dedicated to the hip was developed. (easychair.org)
This software was used to measure acetabular morphological parameters in 61 patients. (easychair.org)
Sucker2
Both genera are similar, however, in having a ventral sucker (acetabulum) smaller than the oral sucker. (cdc.gov)
Noro- lies) of Libertad, for whom fasciolid sucker (acetabulum) was prominent virus recombination in ORF1/ORF2 over- lap. (cdc.gov)
The app is not a simple goniometer, is an enhanced product which help to monitor objectively during the course of the treatment how much is deepening the acetabulum and evaluate the remodelling. (apple.com)
When your hip pain increases to the point that it can not be helped by usual measures such as pain medicine and exercises (physical therapy) and your ability to move your hip decreases, affecting your ability to do your daily activities, it may become necessary to surgically replace the hip joint. (indiahospitaltour.com)
Factors by which the rate increases by raising temperature 10 C (Q10) and apparent activation energy (Ea) values for NADH and MVH activities measured in enzyme preparations without added FAD differed slightly from those measured with FAD. (academicconcepts.net)
Patient2
By clicking three points and inserting the age, the gender and the side of the patient in the App, the measured value is compared with values from normal reference database. (apple.com)
For example, a patient with osteoporosis may require additional measures to ensure the stability of the implant. (surgeonsync.com)
Radiographs2
From postoperative standardized radiographs vertical tilt was measured directly and anteversion was calculated. (nih.gov)
Standard ventrodorsal views of sedated or anesthetized animals can be graded by the Orthopedic Foundation for Animals , or stress radiographs performed and joint laxity measured (Penn Hip). (msdvetmanual.com)
As puppies grow, laxity of the muscles and ligaments surrounding the joint and the poor fit between the bones produces excess movement of the acetabulum. (dpca.org)
6,8 Pincer deformity describes excess coverage of the acetabulum over the femoral head, which can be secondary to coxa profunda or acetabular retroversion. (openmedicalpublishing.org)
Joint4
The hip joint is strengthened by a ligament going directly from the femoral head into and attaching to the acetabulum. (dpca.org)
This is called distraction which is a measure of how loose the joint is. (treendalevet.com.au)
The hip joint is a ball and socket joint and continual abnormal movement of the femoral head (ball) deforms the acetabulum (socket). (acvs.org)
Hip supports are often used to relieve strain on the joint - either to treat an existing complaint or as a preventative measure. (ottobock.com)
Necrosis1
Unfortunately, many patients with fractures of the acetabulum still suffer posttraumatic arthritis or femoral head necrosis regardless of whether operative or non-operative intervention was chosen as the initial treatment. (biomedcentral.com)
Measurements2
We based on two lines for measurements: The first line is the line connecting the highest convex subchondral points on the superior of both acetabulum. (afsu.edu.tr)
A goniometer for angle measurements and tape measure for circumference measurements may be helpful. (medscape.com)
Complications2
Anatomic reduction with rigid internal fixation of the acetabulum has been shown to restore hip function and prevent long-term complications. (biomedcentral.com)
However, it remains disputable whether these techniques are helpful for reconstructing the acetabulum in DDH patients, because these techniques have various complications and uncertain long-term survival rates 9 - 11 . (researchsquare.com)
Additionally2
Additionally, normal growth of the acetabulum depends on normal interstitial appositional growth within the acetabulum. (medscape.com)
Additionally, we measured the distances between the femoral head centers and the acetabular centers in the coronal plane. (bvsalud.org)
Angles2
1,9 Severity is measured with two calculated angles: the alpha (α) and lateral central-edge angles (LCEA) for cam and pincer lesions, respectively. (openmedicalpublishing.org)
Thus, we investigated innominate bone rotation in patients with DDH by measuring the associated angles and distances using three-dimensional (3D) computed tomography. (bvsalud.org)
Head6
The presence of the spherical femoral head within the acetabulum is critical for stimulating normal development of the acetabulum. (medscape.com)
It involves replacing the femoral head with a prosthetic implant while preserving the acetabulum. (surgeonsync.com)
If the connection between the posterior acetabulum and the femoral head shifts under gentle stress, it indicates instability in the hip. (orthofixar.com)
The distance between the centre of the acetabulum and the centre of the femoral head is measured on both views via templates or gauges. (dogsandpupsmagazine.com)
Patients1
A total of 30 consecutive patients were prospectively enrolled and the accuracy of placement of the acetabular component was measured using post- operative CT scans. (easychair.org)
Provide1
They also provide valuable information about the acetabulum, which is crucial for determining the appropriate size and position of the prosthetic implant. (surgeonsync.com)
Clinical2
In a busy everyday practice measuring in X-rays in clinical settings it is time consuming and cumbersome. (apple.com)
Intraoperative measures and preoperative and follow-up clinical, radiological, and functional outcomes were compared between the ORIF and non-ORIF groups. (biomedcentral.com)
Lines1
The distance between these two lines and measured on the trochanter major was defined as ASTM. (afsu.edu.tr)
Actual1
This is a quantitative method that measures the actual amount of hip laxity. (acvs.org)
Evaluation1
One useful index for objective evaluation, how deep the acetabulum is, is the Acetabular Depth Ratio (ADR) or Acetabular Index of Depth. (apple.com)
