Q

What is the injury goes all the way through degenerative cells of the epiphyseal plate? Treatment?

A

Most won’t but if they do it can cause serious damage to the epiphysis and plate and could result in shortening and deformity of limb

Treat with surgery and internal fixation to avoid shortening and deformity of limb

Q

Why is X-ray not as useful in children?

A

Cartilage does not show up as easily so you might not be able to see a fracture –> missed fracture diagnosis

Q

Where are casts placed? Types of cast?

Study These Flashcards
A

Over joint above and below the fracture so completely immobilized like upper extremity, lower extremity and spica

Plaster or Paris or synthetic light weight cast that are more water resistant

21
Q

What are the 5 Ps assessing for? What are they?

Study These Flashcards
A

Assessing for vascular damage

  1. Pain
  2. Pallor
  3. Parathsia
  4. Paralysis
  5. Pulselessness
22
Q

When do you assess the 5 Ps? Why?

Study These Flashcards
A

Prior to and after casting and surgery

May not have initial vascular damage but if cast is too tight or something went wrong in surgery can develop

23
Q

What is club foot? What are the different types of deformities?

Study These Flashcards
A

Congenital malformation of the lower extremity that affects the lower leg, ankle, and foot

One or a combo of
1. Plantar flexion
2. Dorsiflexion
3. Varus deviation (foot turns in)
4. Valgus deviation (foot turns out)

24
Q

What does club foot involve? Is it one or both feet? What are differences in the affected foot? At birth?

Study These Flashcards
A

Involves bone deformity and malposition soft tissue

Can be unilateral or bilateral

Affected foot is smaller and short with empty heal pad and transverse plantar crease

Easily recognized at birth

25
What is the management of club foot?
Serial manipulation and casting If sufficient correction not achieved in 3-6 months --> surgery Long term follow-up
26
What is developmental dysplasia of the hip (congenital dislocation of hip)? Unilateral or bilateral?
Variety of condition when the femoral head and acetabulum are improperly aligned and overtime the acetabulum does not grow appropriately Both unilateral or bilateral
27
What are risk factors for developing developmental dysplasia of the hip?
Twins (overcrowding in uterus) Breech delivery Maternal hormones Large infant (overcrowding in uterus)
28
How do you assess for developmental dysplasia of the hip? When is this done?
Postive Ortolanis maneuver Patient on back without diaper. One hand on hip and other on knee. Flex hip and knee to feel for a click Done at birth and every well baby visit
29
What are the clinical manifestations of dysplasia of the hip in an infant? Child?
Asymmetry in gluteal folds, leg folds, and length of leg Limited ROM in affected hip Asymmetric abduction Femur on affected side appears shorter Everything above plus minimal to prona=ouced variations in gait including lurching toward affected side, limp
30
What is the therapeutic management of dysplasia of the hip in newborn? After newborn?
Splinting the hip w/ pavlik harness to maintain flexion, abduction and external rotation - aligns hip into acetabulum and keeps it there After - traction or surgery to release muscles and tendons
31
Does the harness for dysplasia of the hip need to be worn at all times?
24/7 even when eating and sleeping
32
What is osteogenesis imperfecta? What does this cause? Are there different forms? Most common?
Bones are brittle and extremely brittle and fragile d/t deficit in synthesis of collagen Causes many fractures to occur easily Several forms that vary in severity Autosomal-dominant inheritance pattern most common
33
What are the s/s of osteogenesis imperfecta? (10)
Osteoporosis Excessive bone fragility Increase joint flexibility Blue sclera Discolored teeth Conductive hearing loss by 20-30 Skin can appear translucent Easily bruised Short stature Multiple fractures --> limb and spinal deformities
34
How do you diagnose osteogenesis imperfecta?
History of frequent fractures and clinical evaluation Xray Genetic testing
35
What is the therapeutic management of osteogenesis imperfecta?
Prevention of fractures by being cautious, braces, heel chair Medication: calcitonin and bi[hosphonates Orthopedic stabilizing procedures like traction, casting and fixation
36
How do you diagnose congenital dysplasia of hip?
Screening at birth with ortolani and barlow maneuvers Ultrasound between ages 4-6 weeks Xray for older infants and children
37
What is slipped capital femoral epiphysis (SCFY)? When does it occur? What increases the risk?
Femoral head separates/slip along growth plate --> affects upper femoral growth plate Occurs at time of rapid growth Increase body weight and height are at increased risk d/t increased stress on epiphysis so obese adolescent males
38
What is the patho of slipped capital femoral epiphysis (SCFY)?
Normally epiphyseal plate thins in d/t hormonal influences during adolescence and plate eventually permanently close in adolescence When there is increase body weight and height --> increase stress of epiphyses --> relative displacement/slip of femoral neck from the femoral head --> pain
39
What are the clinical manifestations of slipped capital femoral epiphysis (SCFY)?
Hip pain that is aching or mild along with limp and decreased ROM Aggravated by activity and relieved with rest Pain in groin, thigh, or knee Walk with leg turned outward (externally rotated) to relieve stress and pain in hip joint
40
What is the treatment for slipped capital femoral epiphysis (SCFY)?
Emergency Admitted to hospital and place on bed rest to prevent further slipping Traction to relieve muscle spasms and keep hip in alignment preoperatively Surgical internal fixation to secure to femoral head and prevent further slippage
41
What is scoliosis? What other disorders can it be seen in?
Lateral curvature of spine - compensatory or structural Seen in osteogenesis imperfacta, juvenile arthritis, and spinal cord tumors
42
What is mild scoliosis? Moderate? Severe? What test to confirm?
Mild: 20 degrees Moderate: 25-40/50 degrees Severe: over 50 degrees X-ray to determine curvature
43
What are the s/s of scoliosis? (6)
Rib hump when bending forward Asymmetric rib cage Uneven shoulder or pelvic heights Prominence of scapula (makes wing) or hip Differences in space between arms and trunk when child is standing Apparent leg-length discrepancy
44
How should you have a child stand when assessing for symmetry in scoliosis?
Arms at side, feet shoulder width apart
45
How is scoliosis diagnosed?
Physical exam X-ray
46
What is the therapeutic management of scoliosis? What does it depend on?
Depends on extent of curse, child's age and projected growth, and prescience of associated complications Regular and periodic observation for progression (mild) Bracing - not a cure but will delay/slow progression Spinal fusion surgery (severe)
47
What is some education about a spinal brace that should be discussed? (6)
Brace slows progression but does not protect Brace is worn 23 hours/day and is only off to shower or swim T-shirt worn under brace to protect skin Exercises done several times/day while in brace to correct thoracic lordosis Slight muscle ache common when first wearing brace Encourage teens to be as active as possible when in brace
48
What occurs in spinal fusion surgery? What is post care?
Remove spinous process and can crush to make a paste --> fuse spine Pain management (start with epidural --> IV meds --> PO meds) Foley cath - remove ASAP Mobility - usually up on day 1
