Q

Healing process of fractures in children is…

A
  1. Generally faster r/t rate of growth and no comorbidities
  2. Important not to wait for care w/fractures because the healing and remodeling phase will start quickly and can interfer with proper healing

Q

What factors affect remodeling in children

A
  1. Age: The younger the child the greater remodeling potiental
  2. Location: Growthplates are typically the hardest to heal and can impact the gorwth of the bone due to the complexity of the break
  3. Degree of deformity: Complex/compound fractures will take longer to heal

Q

How are fractures diagnosed?

A
  1. Xray
    • If xray is negative for fracture but childs symptoms suggest a fracture a CT or MRI may be done to r/o a fracture too small for xray to pick up

Q

What are different types of fractures?

A
  1. Plastic deformation (bend): Not an actual break, bones, bones are more pliable so they can actually bend up to 45 degree w/out breaking
  2. Buckle (torus): Bulged or raised area that present at fracture site
  3. Greenstick: break but not all the way
  4. Complete
  5. Spiral: Twisting force seen in sport & child abuse
  6. Growthplate: Epiphyseal break

Q

Why is a cast not applied immediately?

A

The swelling increases the risk of compartment syndrome. If applied when swelling is still present it can cause cast to become to big when swelling goes down

Q

Prior to casting what do we need to ensure?

A

Make sure skin surface is cleaned and dry. We will use a stocking net which is the liner between the skin and cast material folled by a cotton wrap then the cast material is applied

then we mold cast material to limb

Ensure smooth cast edge we may need to bring the stocking net up over the neck of the cast on synthetic casts due to roughness

Q

What are some cast considerations we need to educate patient/parents on?

A
  1. Drys from inside out
    • no heat lamps or warm hair dryers to help speed up the process this increases the risk of burns
  2. Reposition wet casts with palms instead of fingertips
    • using fingertips can leave indentions increasing the risk of skin break down as this can create pressure points
  3. Elevate cast extremity using a soft surface, pillow or blanket
  4. Apply ice but make sure no moisture from cold pack gets into castin material esp. platster because it doesnt have the water resistent liner
  5. Assess 6p’s

Q

What should we know about cast removals and what educationshould we provide?

A
  1. Avoid using the terminology saw… use cast removal tool. and tell them they may feel virbration and tickeling. Kids are scared and will freak if they think you will be using a saw near their legs

Education
1. Appearance: Limb may appear smaller due to muscle atrophy.. may be skinnier, may smell which is perfectly normal.. over time all this will be back to normal
2. Skin care: skin will be dry do not pick at dry skin allow to follow up normally… warm bath with mild soap
3. Return to activity: Full activity for minor breaks rule of thumb is however long you were casted is how long you must wait
4. Joint mobility: may have stiffness but with time will get better

  4. Promote rest/comfort
    • usually self-limiting just take it slow and cautiously
  5. Nutrional considerations
    • high protien because this will help healing
  6. Sugery, possibly
    • if no improvement on antibiotics they may go in for an I&D to clean out dead bone and tissue

Monitor lever and renal function d/t antibiotic

Unknown eitology

More common in the 1st born children, females, postive family hisotry, breech deliever, large birth weight, oligohydramnios

66
Q

What assessment can be done on a newborn 8-12 weeks

A

+ Barlow test
- DDH is present it will be a +barlow test
- ADDuctthe thigh
- Palpable “clunk” of femoral head dislocating from acetabulum

Postive Ortolani test
1. ABdducted while lifting leg anteriorly
2. Palpable “clunk” as dislocated femoral head reduces into acetabulum

After 12 weeks not going to produce a postive result

67
Q

  2. asymmetry of gluteal and thigh folds
  3. postive Galeazzi (allis)sign
    • Shortness of the femur with the hips and knees flexed
  4. Leg length discrepancy
69
Q

On our assessment of DDH what might we see in older infants and children?

A
  1. Postive trendelnburg signs
    • Child stands on one foot at a time
    • when weight is on affected hip, pelvis tilts downward on the normal side instead of upward as it should
  2. Leg length discrepancy
  3. Telescoping mobility of joint
  4. Marked lordosis and waddling gait (bilateral dislocations)
70
Q

How is DDH dx?

A
  1. Physical assessment
  2. Xray- not reliable if the child is under 4 months old child will need ultrasound
  3. Ultrasound: can be done as early as 2 weeks old
71
Q

What are our interventions for DDH?

A

Birth to 6 months
1. Pavlik harness
- Maintains flexion and abduction of hips
- Worn continuously (full-time) for 6-12 weeks
- HCP will adjust the brace ever few weeks.
- Will do ultrasound and xrays to watch for progress

72
Q

What education do we need to provide about Pavlik brace?

A
  1. Application and maintenance of device
    • fit of harness (HCP adjusts)
    • Skin care (cotton onside under harness parents will be taught how to take off and on for baths teach how to assess skin, No lotions,creams, powders, diaper goes UNDER strap
  2. Encourage parents to hold infant with harness
  3. Involve infant in activites with others
73
Q

What interventions do we implement for infants 6-24m with ddh who are no longer a candidate for palvik brace?

A
  1. Bryants traction: Skin traction bottom off bed
  2. Surgical reducation (open vs. Closed) to reduce hip joint
  3. Spica cast (after surgery typically on for 12 weeks)
  4. Flexion abduction brace (graduate to this haver fully heal and out of the SPICA cast some use it some dont.)
74
Q

What interventions do we implement for children older than 24 months with DDH that are no longer a candidate for the palvik brace?

A
  1. Open reduction
  2. Spica cast after surgery
  3. Flexion-abduction brace.

Surgical intervention is extremely difficult if caught after the age of 4 and pretty close to impossible if after 6 years due to severe shortening and contractures of the muscle.
