|What is the angle between the neck and the shaft of the femur in the frontal plane is called? ||angle of inclination|
|When is the angle of inclination the largest? ||at birth|
|The angle of inclination __________ until adulthood. ||decreases|
|What is considered normal for the angle of inclination? ||125°(may range from 115°-140°)|
|If the angle of inclination smaller or larger in women? ||smaller|
|The angle between the neck and shaft of femur in horizontal plane is called?
||the angle of anteversion(torsion)|
|What is the average angle of anteversion? ||10°|
|How could anteversion manifest in observation or gait ?
|How could retroversion manifest in observation or gait ?
|The hip joint is designed for ______, while the glenohumoral joint is designed for ______ .
|The acetabular labrum is made up of what kind of cartilage? ||fibrocartilage|
|The acetabular labrum is attached to what two structures? ||acetabular rim and transverse ligament|
|What is the function of the labrum? ||to make the acetabulum more concave to increase stability.|
|Give two examples of fibrocartilage in the body?(besides the labrum) ||meniscus of knee, IV discs of spine|
|The ligaments of the hip are considered either _________ or _________. ||intracapsular or capsular|
|Which ligaments are considered intracapsular? ||transverse ligament and ligament of the head of the femur (ligamentum teres) |
|What ligament completes the gap of the acetabular notch? ||transverse ligament|
|Ligamentum teres attaches where? ||acetabular notch/transverse ligament to the
fovea of the femur.
|Does the ligamentum teres provide much joint stability? ||no|
|What is the main purpose of the ligamentum teres? ||to provide blood supply to femoral head until growth plate closure.(16-20 y/o)|
|What are the potential consequences of ligament disruption ||avascular necrosis|
|Where is the joint capsule the thickest/strongest? ||anteriorly and superiorly|
|What kind of membrane lines the capsule? ||synovial membrane|
|What are the capsular ligaments? ||Iliofemoral, Ischiofemoral, and Pubofemoral
|The Iliofemoral, Ischiofemoral, and Pubofemoral ligaments all tighten up with what motion?
|Which ligament is located primarily posterior to joint and wraps around from post. to ant. And tightens up with extension?
|Which ligament is located anterior and inferior to joint? ||pubofemoral|
|Which ligament is located primarily anterior to the joint and is also known as the Y ligament of bigelow? ||Iliofemoral|
|All capsular ligaments become taut in what hip motion?
|The position where, overall, joint surfaces are least congruent, least compression of the joint surfaces, capsule and ligaments are maximally relaxed, space & volume maximal, maximal distraction is possible & greatest movement available is what position?
|What is the clinical significance of the resting position? ||allows for joint play assessment, its the position of comfort following injury when swelling is present|
|What is the resting position of the hip(specific positions and degrees)? ||30° Flexion, 30° ABD, 30° ER
|What is the position where overall, the ligaments are maximally stretched and there is maximal congruency of articular surfaces?
||closed packed positoin|
|What is different about the hip's closed packed position? ||it has a bony closed packed position and a ligamentous closed packed position|
|What is the bony closed packed position of the hip? ||90° Flexion, Slight abduction, Slight ER
|What is the ligamentous closed packed position of the hip? ||Full extension, Abduction, IR
|What three motions are primarily limited with a capsular pattern? ||IR, flexion, abduction|
|Discuss how swelling differs w/ intracapsular vs capsular ligamentous sprains. ||Expect more swelling throughout jt in intracapsular sprain vs a minor/superficial/absent swelling w/ capsular sprains.|
