Hip COPY

Question 1

FAI: CAM

Answer 1

Morphological abnormality of superior-anterior aspect of the femoral head neck

Question 2

FAI: Pincer

Answer 2

Excessive bone growth of the superior anterior aspect of the acetabulum

Question 3

FAI: Demographics

Answer 3

• 20-40 years old
• male
• groin pain w/ hip rotation, in sitting position or after sports

Question 4

FAI: Clinical Exam

Answer 4

• loss of hip IR
• limited flexion
• grinding/popping w/ hip ER

Question 5

Labral tear:

• most common MOI?
• most common location?

Answer 5

• MOI: rotation in weightbearing

- location: anterior

Question 6

4 types of labral tears:

Answer 6

• radial flap
• longitudinal peripheral
• radial fibrillated
• abnormally mobile

Question 7

What is the most valid test for dx of a stress fracture?

Answer 7

• fulcrum test

Question 8

Snapping Hip Syndrome:

• AKA:
• Sx:
• External vs Internal:

Answer 8

AKA: Coxa Saltans

• Sx:
  
  • snapping sensation in and around hip when it is in motion
• External vs Internal:
  • external (most common) IT band; snapping over the greater trochanter
  • internal: iliopsas tendon snapping over the bony prominence of the pelvis (Femoral triangle, lesser trochanter)

Question 9

Most common injury to the lateral knee?

Answer 9

IT band syndrome

- inserts on gerdy’s tubercle & proximal aspect of the fibular head

Question 10

Sports hernia:
AKA:
Treatment:

Answer 10

AKA: Athletic Pubalgia

Chronic, conservative management doesn’t work

Question 11

Define femoral anteversion

- Test?

Answer 11

Anything greater than 15 degrees

Craigs Test: measures femoral antversion and retroversion

Question 12

What are possible compensations of femoral anteversion?

Answer 12

• external tibial rotation
• lateral rotation at the knee
• lumbar rotation to the same side

Question 13

What is an indicator that a hamstring injury will take longer to rehabilitate?

Answer 13

Injury to the proximal free tendon

- ie. Semimembranous during kicking or dancing

Question 14

What is an indicator that a hamstring injury will take LESS time to rehabilitate?

Answer 14

Injury to intramuscular tendon or aponeurosis

- ie. Biceps femoris during high speed running

Question 15

What are the borders of the femoral triangle?

Answer 15

Superiorly: inguinal ligament
Medially: medial border of adductor longus
Laterally: medial border of sartorius
Floor: Adductor longus, Pectinus, and iliopsas

Question 16

What is a precipitating factor in adductor strains?

Answer 16

Adductor strength

Question 17

When do you initiate eccentric hamstring activation in hamstring strain rehab?

Answer 17

Phase II

Question 18

What is the normal angle of inclination?

Answer 18

125-130 degrees

Question 19

What does the center edge angle measure?

Answer 19

Normal seating of the femoral head (normal = 20-25 deg)

Less than 20 deg = acetabular dysplasia

Question 20

Pincer FAI on XRay: what sign would you see?

Answer 20

Cross over sign

Question 21

CAM FAI on XRay: what would you see?

Answer 21

pistol grip deformity on femoral neck

Question 22

Frontal plane pelvo-femoral stability is mediated by what muscle groups?

Answer 22

Gluteus medius
tensor fascia latae
adductor complex
quadratus lumborum

Question 23

What is the most significant risk factor for SCFE?

Answer 23

Obesity

Question 24

What mechanical version will you see in a patient w/ SCFE?

Answer 24

Femoral or acetabular retroversion

Question 25

How should a SCFE be managed? Stable or Unstable

Answer 25

ORIF
