Flashcards in The hip Deck (12):
1

blood supply to the head and neck of femur

superior - branch of the obturator artery
inferior - lateral femoral circumflex artery and medial circumflex artery

2

#NOF

intracapsular - proximal to intratrochanteric line
extracapsular - distal to intratrochanteric line

3

trendelenbergs sign

shows weakness n the gluteus medius on the leg standing on the floor

4

common hip problems

childhood: developmental dysplasia of the hip (DDH) (0-3yrs); Pethes disease (4-8yrs); slipped upper femoral epiphysis (SUFE)(10-15+yrs)
adult: arthrits

5

perthes disease

temporary disruption to the blood flow to the head of the femur. this can lead to avascular necrosis

6

DDH

incindence - 1-2/1000
risk factors:
girls:boys 7:1
FH
breech
post natal position

7

tests for DDH

done during 6 week check
Galeazzi's sign
Barlo's test
Ortolani's test

8

Tx for DDH

harness maintaining hips in congruent reduction will allow normal hip development. late presentation will require surgical repair

9

Perthes

age 4-8years
incidence 1/10,000
boys:girls 4:1
pain, limp, limited ROM
unknown cause
transient AVN of femoral epiphysis
revascularisation
repair
remodelling

10

Tx of perthes

pain relief
maintian ROM
containment of the head of the femur
maintain shape
surgery

11

SUFE

during pubertal growth spurt
boys 12-16, girls 10-15
hormonal imbalance (GH>sex) - fat, hypogonadal; tall, thin; hypothyroid
trauma
acute or acute-on-chronic
bilateral ~30%

12

Tx of SUFE

surgery to pin head of femur back into correct position
