Q

Ischiopubic rami

A

Combined form of ramus of the ischium and the inferior pubic ramus

19
Q

Inguinal Ligament

A

The boundary between the lower limb and the abdomen
-ASIS and pubic tubercle are attachments of inguinal ligament
-Inguinal region is the depression between the abdomen and thigh (referred to as groin)

20
Q

Hip (Coxafemoral Joint)

A

-Head of femur articulates with the acetabulum
-Synovial
-Multiaxial
-Ball and Socket
-Head of femur projects medially, superiorly, & anteriorly
-Acetabulum projects laterally inferiorly, & anteriorly

21
Q

Available Motions at Hip Joint

A

-Flexion
-Extension
-Medial Rotation
-Lateral Rotation
-Abduction
-Adduction

22
Q

Articular Surface of the Acetabulum

A

-Horseshoe Shaped

23
Q

Articular Cartilage

A

-Covers head of the femur and the horseshoe shaped part of the acetabulum
*Articular cartilage is part of a synovial joint

24
Q

Ligament of the Head of Femur

A

-a.k.a ligamentum teres, round ligament, foveal ligament
-Connects head of femur to the acetabulum

25
Q

Acetabular Labrum

A

-Fibrocartilagenous lip that attached to the bony rim of acetabulum
-Functions to deepen acetabulum (make ‘socket’ a deeper socket)

26
Q

Acetabular Fossa

A

-Centre of acetabulum
-Fossa is occupied by fat pad covered with synovium

27
Q

Acetabular Notch

A

-Notch between the 2 ends of the horseshoe
-Passage for blood vessels

28
Q

Transverse Ligament of Acetabulum

A

-Connects (closes) the acetabular notch

29
Q

Ligaments of the Hip

A

-All the capsular ligaments of the hip are coiled or twisted as they pass from the pelvis to the femur (in a neutral position)
-Extension/hyperextension tightens them further making extension part of the close-packed position and a position of stability in an upright posture
-Conversely, full hip flexion with abduction is an unstable position

30
Q

Iliofemoral Ligament (Y ligament)

A

Attaches: AIIS, acetabular rim - intertrochanteric line of femur
Checks: extension, abduction, lateral rotation

31
Q

Pubofemoral Ligament

A

Attaches: superior pubic ramus - iliofemoral ligament
Checks: abduction

32
Q

Ischiofemoral Ligament

A

Attaches: ischial part of acetabular rim - femoral neck and medial greater trochanter
Checks: hyperextension

33
Q

Trochanteric Bursa

A

-Between the gluteus maximus muscle and the (postero-lateral) greater trochanter

34
Q

Ischiogluteal Bursa

A

-Overlying the ischial tuberosity
-Weavers bottom (layman’s term for ischiogluteal bursitis) - people weaving would have to extend one leg forward then the other - the repetitive position changes put excessive pressures on the ischial tuberosity and therefore the bursa

35
Q

Weavers bottom

A

(layman’s term for ischiogluteal bursitis)
-People weaving would have to extend one leg forward then the other - the repetitive position changes put excessive pressures on the ischial tuberosity and therefore the bursa

36
Q

Iliopectineal Bursa

A

Between the iliopsoas muscle and the iliopubic eminence

37
Q

Pubic Symphysis (a.k.a. Symphyis Pubis)

A

-Joint between the 2 pubic bones
-Cartilaginous Joint (there is cartilage between 2 ends)
-Fibrocartilagenous disc between 2 bones which acts as a shock absorber
-Limited movement
-Ligaments: superior pubic ligament, inferior pubic ligament

38
Q

Sacroiliac Joint

A

-Joints between ilia and sacrum (sacrum is suspended between the ilia)
-Synovial Joints (very strong joint - capsule is strong, ligaments are strong, etc.)
*Does not fit under specific joint category
-Surfaces are irregular in shape and contour (elevations and depressions) which result in. a partial interlocking of the bones
-Limited movement (trade mobility for stability)
-Ligaments: anterior and posterior sacroiliac ligaments

39
Q

Pelvis is held together by _________________.

A

Ligaments

40
Q

Ligaments (and the pubic symphysis) progressively _____________ during pregnancy to allow passage of the fetus through the birth canal.

A

Relax

41
Q

Iliolumbar Ligament

A

-TVP’s L4 & L5 to the posterior iliac crest
-Key stabilizer of L5
-Limits/checks/restricts lateral flexion

42
Q

Sacrotuberous Ligament

A

-Posterior surface of the sacrum/coccyx to the ischial tuberosity
-Stabilizes the SI joint and provides a surface attachment for gluteus maximus

43
Q

Sacrospinous Ligament

A

-Lateral sacrum/coccyx to the ischial spine
-Converts the greater sciatic notch into the greater sciatic foramen
