29
Q

What is the acute management of Juvenile idiopathic arthritis

A

Physio

Pain relief - NSAIDs

30
Q

what is the chronic management of juvenile idiopathic arthritis

A

Disease modifying drugs - methotrexate/sulfasalezine
Folic acid
pain relief

31
Q

What are the risk factors for Developmental Dysplasia of the hip?

A
  • First born
  • Female
  • Breech
  • FH
  • Oligohydramnios
  • Macrosomia
  • Swaddling - cultural
32
Q

Dysplasia definition

A

Shallow or underdeveloped acetabulum (usually ant or anterolateral)

33
Q

Subluxation definition

A

displacement of the joint with some contact remaining between the articular surfaces

34
Q

What is a teratologic hip

A

o dislocated in utero and irreducible on neonatal exam
o presents with a pseudoacetabulum
o associated with neuromuscular conditions and genetic disorders
o commonly seen with arthrogryposis, myelomeningocele, Larsen’s syndrome, Ehlers-Danlos

35
Q

What does the barlow test do

A

Dislocates a dislocatable hip by adducting and depressiong a flexed femur – ‘click of exit’

36
Q

What does the ortolani test do

A

Reduces a dislocated hip be elevation and abduction of a flexed femur – ‘click of entry’

37
Q

What is the Galaezzi test

A

Hip flexed at 90 degrees, feet on table, femur appears shortened on dislocated side

38
Q

what would you find on examination between 3-12 months in developmental dysplasia of the hip

A
  • Limitations of hip abduction: laxity resolves and stiffness begins to occur (most sensitive) Will be decreased symmetrical in bilateral disloations.
  • Limb length discrepancies
39
Q

What is the klisic test

A

o used to detect bilateral dislocations
o line from the long finger placed over the greater trochanter and the index finger over the ASIS should point to the umbilicus
o if the hip is dislocated, the line will point halfway between the umbilicus and pubis

40
Q

What would you find on examination >12 months in a child with developmental dysplasia of the hip?

A
  • pelvic obliquity
  • lumbar lordosis: in response to hip contractures resulting from bilateral dislocations in a child of walking age
  • Trendelenburg gait : results from abductor insufficiency
  • toe-walking: attempt to compensate for the relative shortening of the affected side
41
Q

When would you do an Xray if suspected developmental dysplasia of the hip

A

o Primary imaging >4-6 months as femoral head begins to ossify
o Positive physical exam
o Leg length discrepancy
- AP view of pelvis

42
Q

When would you do an US scan if suspecting developmental dysplasia of the hip

A
  • 4 weeks – 6 months
  • Positive physical exam
  • RF
  • Monitoring of reduction using Pavlik harness
  • Not cost effective for routine screening
43
Q

What are the non operative management options for developmental dysplasia of the hip

A
  • abduction splinting/bracing (Pavlik harness)

-

44
Q

indications/contraindications for abduction splinting/bracing (Pavlik harness)

A
  • Indications
    o < 6 months old and reducible hip
  • Contraindications:
    o teratologic hip dislocations and patients with spina bifida or spasticity
     requires normal muscle function for successful outcomes
45
Q

What are the indications for closed reduction and spica casting

A

o 6-18 months old

o failure of Pavlik treatment

46
Q

What are the operative management options for developmental dysplasia of the hip

Open reduction and spica casting
Open reduction and femoral osteotomy
Open reduction and pelvic osteotomy

47
Q

What are the indications for Open reduction and spica casting

A

o > 18 months old

o failure of closed reduction

48
Q

What are the indications for Open reduction and femoral osteotomy in developmental dysplasia of the hip

A

o > 2 years old with residual hip dysplasia
o anatomic changes on femoral side (e.g., femoral anteversion, coxa valga)
o best in younger children (< 4 years old)
- after 4 years old, pelvic osteotomies are utilized

49
Q

What are the indications for Open reduction and pelvic osteotomy

A

o > 2 years old with residual hip dysplasia
o severe dysplasia accompanied by significant radiographic changes on the acetabular side (increased acetabular index)
