Flashcards in hip Deck (36):
1

main hip flexor

iliopsoas

2

main hip extensor

gluteus maximus

3

main hip abductor

gluteus medius

4

main hip adductor

adductor magnus

5

main hip internal rotator

tensor fascia lata

6

main hip external rotator

gluteus maximus

7

what is a significan LLD?

2 cm

8

Proximal weakness is evidenced by a _________gait where the patient is relying on ________muscles, rather than flexor/extensors

Trendelenburn, abductors

9

This test puts patient in extended butterfly and tests the _______ joint

FABER, SI

10

This test is the same as the obturator test

FADIR (flexion adduction, internal rotation)

11

This problem is more common in males in 30's-50's who present c/o a dull ache/throbbing pain around hip (groin, lateral, or buttocks). It is most common in people with h/o EtOH, steroid use, SCC, or chemo

osteonecrosis of the femoral head (AVN)

12

Osteonecrosis AVN occurs over 5 stages on xray. What are they?

0) No change on xray
1) mottled densities
2) crescent sign, increased densities in femoral head
3) flattening of femoral head, normal joint space
4) narrowing joint space, acetabular changes
5) advanced degenerative changes

13

How can you treat ON/AVN of femoral head?

1) before collapse: core decompression
2) after collapse: hemi-arthroplasty or total hip

14

How many patients go on to have ON/AVN of the other hip?

50-90%

15

This problem is caused by friction from overuse, trauma, or a direct blow.

bursitis

16

This bursitis is worst when seated

ischial bursitis

17

This bursitis is due to microtrauma and s/s include anterior hip pain. Relief with hip flexion and external rotation

ilio-pectineal bursitis

18

this bursitis is a/w LLD, broad pelvis, poor running, and tight IT band. Worse with external rotation. Positive Ober test

trochanteric bursitis

19

Another term for sciatica is?

piriformis syndrome

20

nerve pain over the lateral thigh, most often in obese patients is likely affecting the ________nerve

lateral femoral cutaneous

21

If missed, _________ and __________ are a/w a 50% mortality rate in the setting of pelvic fx

vaginal laceration or perforated colon

22

What type of hip fx occurs just under the ball of the hip joint?

subcapital neck fx

23

what type of hip fx occurs mid neck?

transcervical neck fx

24

what type of hip fx occurs between the base of the neck of the femur and the base of the trochanters?

intertrochanteric fx

25

what type of hip fx occurs below the trochanters

subtrochanteric

26

What type of hip fx avulses the upper/lower trochanter

Greater/lesser trochanteric fx

27

What is included in "intracapsular" fractures?

femoral neck and capitulum

28

what is the likely MOI for intracapsular fx?

indirect shear force on angulated femoral neck.

29

PE for intra-capsular

shortened leg, external rotation, painful ROM

30

PE for extra-capsular

MORE external rotation, significant blood loss, no wt bearing

31

Most common type of hip dislocation

posterior

32

What is the MOI for posterior hip dislocation?

femoral head forced backward, tearing ligamentum teres and posterior capsule, fx of acetabulum

33

What are you worried about with posterior hip dislocation?

AVN, emergency reduction

34

What does leg with posterior hip dislocation look like?

internal rotation, hip flexed and adducted

35

what is the MOI for an anterior dislocation?

forceful abduction and external rotation

36

What do you notice on PE for anterior hip dislocation?

palpable groin mass, external rotation
