Exam Q: Hip region

Question 1

Name the bone

Answer 1

Pelvic bone

Question 2

Classify the bone according to its shape. Why is it classified this way?

Answer 2

Irregular.

Does not fit into any of the other categories

Question 3

Side the bone. Why is it from the … side?

Answer 3

Right/left.
Proximal end: iliac crest

Lat: acetabulum

Ant: ASIS

Question 4

Identify the 3 major components and the major bony features for each component:

Answer 4

ILIUM: (proximal)

• Iliac crest,
• ASIS, PSIS,
• tubercle of crest
• inf, ant, post gluteal line

ISCHIUM: (distal + posterior)

• tuberosity,
• ramus

PUBIS: (anterior)

• tubercle,
• body
• sup pubic ramus,
• pectineal line,
• pubic crest,
• inferior pubic ramus,
• obturator groove

Question 5

Name the joints the bone participates in

Answer 5

Hip joint

pubic symphysis

sacroiliac joint

Question 6

With reference to the hip jt - identify the type of joint and the articular surfaces

Answer 6

Ball + socket jt

Spherical head of femur + lunate surface of acetabulum of hip bone

Question 7

Describe and identify location of anatomical structures that contribute to the STABILITY of hip jt:

Answer 7

EG:

Bone ends - Ball & socket

Acetabular labrum: attached to margin of acetabulum

Capsule: thicker ant.sup where max stress occur in standing. Reinforced by 3 lig:

• Iliofemoral lig: (ANT) limits extension in standing.
• Pubofemoral lig: (ANT.INF) Thightens during extension + abduction.
• Ischifemoral lig (POST): ??
• Tips: All taut in ext, relaxed in flex

M: Glut max, med, Add L, Piriformis..

Question 8

On the model, palpate the major bony features around hip region

Answer 8

• Iliac crest
• ASIS
• PSIS
• GT
• ischial tub

Question 9

On the model, name and identify the location of the major blood vessels and nerves that traverse hip region

Answer 9

Blood vessels: Femoral artery + vein (ant to jt)

Nerves: Femoral (ant) + sciatic (post to jt)

Question 10

Name and demonstrate movements (incl plane + axis) that occur at the hip jt (use model)

Answer 10

Flex/ext: Sagittal plane, frontal axis

Abd/add: frontal plane, sagittal axis (OBS!)

Med/lat rotation: Horizontal plane, vertical axis

Question 11

Select 2 movements that occur at the hip jt:

For each movement:

• Name the movement
• Name the major M group involved
• on the model, identify location of M group + palpate M belly + tendons
• Demonstrate the major M group working either concentrically or eccentrically

Answer 11

EG: FLEXION

• flexors of the hip
• ant to the hip jt
• Exercise; contcentric - Hip flexion

Question 12

Explain why extension of knee jt in conjuction with hip flexon may limit hip flexion ROM?

Use model

Answer 12

Passive insuffiency of hamstrings (lengthened over both hip + knee jt)

Question 13

Position Rec fec in its lengthened position

Use model

Answer 13

Prone lying: Knee flexion + hip extention

Question 14

Demonstrate how you would test for the Trendelenberg sign (use model)

Differentiate between a +ve and -ve sign.

What M/group is involved?

Answer 14

Standing on one leg. Note position of pelvis and trunk.

+ve: drop of pelvis to side of the liften leg.
