Q

Q: What is the important about the “fetal position”?

A

The fetal position is important of the development of the acetabulum. A cradle board (common in native american culture) or extended positions results in shallow acetabulums and a higher risk of hip dysplasia.

Q

Q: What are 3 important factors of a ped eval?

A
  1. Birth history - timing and type
  2. Developmental milestones
  3. Parent intuition
17
Q

Q: We are ________ in rating our pain but ___________ with ourselves.

A

unique, consistent

18
Q

Q: What are 3 important factors of a ped phsyical exam?

A
  1. Trust - pt. and parent
  2. Observation of spontaneous movements - kids like to perform
  3. Age appropiate verbal commands
19
Q

Q: What is Gower’s sign associated with?

A

Muscular dystrophy (walking hands up legs to stand)

20
Q

T/F: We are least mobile in infancy

A

False

21
Q

Q: What is the difference between growing pain and pain due to growing?

A

Growing pain = poorly localized, at night, no altered function, spontaneously resolves

Pain due to growing

ex. bones grow faster than mm, which results in tightness followed by compensations that cause pain
ex. overuse of developing structures results in pain

22
Q

T/F: MMT is appropriate at all ages.

A

False, not under the age of 5(ish)

23
Q

Content: Talipes Equionvarus (Club Foot) (3)

A
  1. Equinus, varus, adductus
  2. Mild = serial cast
  3. Severe = sx correction at 4-6 mo
24
Q

Q: What are 4 tests for developmental dysplasia of the hip?

A
  1. Barlow - distraction in ABD/ER/Flex
  2. Ortolani - distraction in ABD/ER/Flex
  3. Galeazzi sign - knee unlevel in supine hook lying
  4. Asymmetry of thigh folds
25
Q

Content: Congenital Muscular Torticollis (5)

A
  1. Shortened SCM
  2. Lateral flexion on short side with rotation on opposite side
  3. Can cause cranial/facial deformity
  4. DDX = vision deficits
  5. Primarily treated with botox and PT when < 1 yo
26
Q

Content: Legg-Calve-Perthes (5)

A
  1. Locailzed
  2. Boys (> girls), 3-13 yo
  3. Loss of IR, ABD, Ext
  4. Antalgic and trendelenberg gait
  5. PT = core stab, limited WB, activity modification, compliance
27
Q

Q: What is the motion limitation in Legg-Calve-Perthes?

A

Lack, ER, ABD, Ext of hip

28
Q

Content: Slipped capital femoral epiphysis (SCFE) (6)

A
  1. Due to mechanical stress
  2. Onset at puberty
  3. Limited IR, ADD, Flex
  4. Hallmark: ER with attempts of increased hip flexion
  5. Sx w/in 24 hrs to protect against AVN
  6. PT = Core stab, progressive WB
29
Q

Q: What is the motion limitation in SCFE?

A

Lack, IR, ADD, Flex of hip

30
Q

Content: Tibia vara (Blount’s) - asymmetric (3)

A
  1. Bow legged stance of one leg
  2. Sharp varus of metaphysis, wedging of medial epiphysis, widening growth plate, beakin of medial metaphysis
  3. Depending on age: HKAFO, tibial osteotomy, external fixation
31
Q

Q: What 2 types of fx are more common in peds?

A
  1. Avulsion
  2. Bending
32
Q

Defn: Buckle or Torus Fx

A

Compression fx resulting in a bulge in the cortex

33
Q

Q: Which Epiphyseal injury is most alarming?

A

Type 5 - will not show up on x-ray but rather years later when growth arrest is noticeable

34
Q

Content: Limb shortening (5)

A

Best practice is the arrest growth of the long limb

Options

  • Physeal arrest: 2-5 cm
  • Shorten femur: 5-6 cm
  • Shorten tibia: 2-4 cm

Caution

  • Can affect proportion/changes knee center
35
Q

Q: When would you lengthen the short limb?

A

When the discrepancy is greater than 5 cm

36
Q

Q: How do you lengthen a bone?

A

distract the fx .25 mm 3-4xday, do not exceed 1 mm/day of lengthening

37
Q

Q: When do the arches of the foot develop?

A

3-5 yo
