Answer |
| 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 ?
| pigeon toes |
| How could retroversion manifest in observation or gait ?
| toe out |
| The hip joint is designed for ______, while the glenohumoral joint is designed for ______ .
| stability, mobility |
| 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?
| extension |
| Which ligament is located primarily posterior to joint and wraps around from post. to ant. And tightens up with extension?
| Ishiofemoral ligament |
| 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?
| extension |
| 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?
| Resting 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 |
