25
What is spondylolysis/Spondylolithesis?
Degeneration of spinal discs and joints (lysis) leads to segmental instability and displacement over time (lithesis)
26
What is the Cobb angle?
Degree of curvature of the spine - Draw lines from the most tilted vertebrae above and below the curve's apex. Measure the angle between two intersecting lines perpendicular to the tilts. (I cannot describe this, picture slide 20 is great) Measurement of the cobb angle is essential to determine management of scoliosis an risk progression
27
What is the Risser Sign?
The degree of ossification of the iliac crest, maturity occurs in a stepwise fashion from lateral to medial - can be used to assess skeletal maturity using an x-ray. Can correspond to menarche status in females
28
What patients with idiopathic scoliosis require monitoring and treatment?
Monitoring --> Angle < 25° & pt still growing --> Curve > 45° and finished spinal growth Treat is pt is still growing and --> Angle > 25° (bracing for Risser 0-2) --> Cobb angle > 45-50° at time of diagnosis will likely require treatment
29
What is the purpose of bracing for scoliosis? What Risser stage can it be attempted on?
Does not correct curvature, simply stops it - Reduces the chance of progressing to require surgery Must be skeletally immature (Risser 0-2)
30
What are the two kinds of bracing for scoliosis?
TLSO --> Thoracolumbarsacral orthosis Providence --> Night time only
31
How much time should be spent in a scoliosis brace daily?
18-24 hours daily --> 72% success rate at preventing surgery
32
What is the goal of operative interventions for scoliosis? What are two main types?
To prevent curve progression through spine stabilization --> Growth modulation techniques --> Definitive Fusion MAGEC rods - magnetic growing rod Vertebral Body Tethering Posterior spinal fusion - wait until child is not growing to allow lung capacity to develop
33
What is a MAGEC rod?
A magnetic rod that grows with the child and prevents curve progression with scoliosis
34
What is vertebral body tethering?
Tension on vertebrae to correct curvature, helpful for patients still growing
35
What is the gold standard treatment for scoliosis?
Spinal fusion --> Correction comes from healing phase following 6 months after fusion
36
What are nursing roles with pre-op patients?
Review day-to-day protocols, expectations for surgery so they know what to expect Assess mental health
37
How is mental health of children affected by scoliosis or spine disorders?
Children with ortho conditions are at increased risk of depression --> may be d/t bracing, poor body image, stress factors related to surgery
38
What is the ASQ?
Ask suicide-screening questions --> Tool that can identify adolescents at risk of suicide
39
What is covered in a HEADS assessment?
Home Education Activities/Anxiety Drugs Sex/Suicide
40
What happens if a person has a positive ASQ screen?
Referral to mental health team before d/c
41
What is the correlation between HEADS assessments and a positive ASQ screen?
Patients with a positive HEADS assessments are more likely to have a positive ASQ screen Psychosocial risk factors --> Increased risk of suicidal ideation
42
What are the main goals of post-op recovery following spinal surgery?
Pain management, early mobilization, fluid balance and regulation, diet tolerance same as usual
43
What assessments must nurses perform regularly following spinal surgery?
VS, neurovascular, ankle dorsiflexion
44
What restrictions are in place for someone who has gone through spinal surgery?
Keep in mind this will be teaching bc d/c is usually day 3. --> No shower 5-7 days, no soaking for 6 weeks --> Return to school 1 month post op --> No contact sports 6 months
45
What is a common finding immediately post-op for spinal surgery?
Numbness - often resolves
46
What non-pharmacologic pain management can be helpful for spinal post-op?
Warm compresses, frequent position changes
47
Early hip development progresses until what age?
Progresses until 6-8 and continues into adolescence
48
How does the hip differ in children and adults?
Acetabulum and femoral head are cartilaginous in children
49
What is developmental dysplasia of the hip (DDH)?
Refers to a spectrum of abnormality in the developing hip
50
What is the most common MSK abnormality in the NB period?
DDH
51
Mild dysplasia with mild instability for the first few weeks of life generally has a benign course. When should we begin to worry about DDH?
Frank dislocation often leads to progressive dysplasia - spontaneous resolution in baby over 6 months is not likely (intervention is needed)
52
What are the 5 Fs of risk factors for DDH?
Family Hx Fetal breech position Fluid - oligohydramnios First born infant Females "packaging disorder"
53
What is club foot?
Inward deviation of metatarsals - associated with DDH
54
What is dysraphism?
An umbrella term for a number of conditions where the spine and spinal cord do not develop normally --> Such as spina bifida
55
What is congenital torticollis?
A condition where the infant neck muscles contract and cause head tilt to one side --> Indicative of spinal abnormalities
56
Asymmetrical creases or decreased ROM of hips can indicate what?
Hip dysplasia/dislocation
57
What are the Barlow and Ortolani Maneuvers?
Tests hip stability. Barlow --> Flex + adduct hip joint. Positive test results is palpable posterior dislocation Ortolani --> Flex + abduct hip, femoral head will reduce into acetabulum and audible clunk will be heard and felt.
58
What is the Galeazzi sign?
Asymmetrical knees when supine and soles of feet brought flat to surface
59
How does swaddling affect the hips?
Cultures that keep hips and legs together in extended knee position have higher rather of hip dysplasia Keeping baby's hips in M position is better
60
How can we treat hip dysplasia under 6 months?
Pavlik harness --> 12 weeks treatment (6 full/6 nights only) Goal is to obtain and maintain concentric reduction of the hip and allow for healthy development of the acetabulum and hip joint
61
When is a fixed harness (Rhino) or spica cast indicated for hip dysplasia?
Pavlik harness has failed, or the child is over 6-12 months
62
Up to what age can a spica cast be used to treat hip dysplasia?
Up to 2 years it can be tried with closed reduction
63
What are some procedures that would result in a spica cast being needed?
Femur fracture DDH Pelvic osteotomies Some treatments for cerebral palsy
64
What positioning is important for a child in a spica cast?
Well supported, prevent pressure sores --> Consider bean bag or spica table
65
What position should a child who had a osteotomy be in post-op? Why?
Head above legs (reverse Trendelenburg) --> anticipate edema, especially genital swelling
66
What is important parent teaching is a child had a spica cast?
Diaper care --> Must keep case clean, it cannot be removed and if it is soiled there will be skin breakdown --> On similar vein, keep food off of it Clothing on upper body only Watch skin for sores
67
What assessments are used to detect (not Dx) scoliosis?
Inspect for asymmetry Adam's forward-bending test (AFBT) Scoliometer (optional)
68

70
What is plagiocephaly?
Development of a flat spot of part of the skull
71
What is arthrogryposis? What causes it? How it is diagnosed and managed?
A number of congenital conditions characterized by stiff joint or abnormal muscle development. This condition is not progressive. Etiology - might be obstruction to uterine movement, early viral infection in utero. Diagnosis - Hx, examination. Imaging may also be used Management - OT, orthopedic surgery.
72
What are the three degrees of DDH?
1. Acetabular dysplasia 2. Subluxation 3. Dislocation
73
How is club foot diagnosed and managed?
Dx: Deformity readily apparent prenatally through ultrasound or at birth Management: Goal is to achieve painless, plantigrade, stable foot through correction of deformity, maintenance of correction, and follow-up observation
74
What is osteogenesis imperfecta? How is it managed?
Genetic disorder characterized by bones that fracture easily Managed supportively - bisphosphates + Ca + Vit D
75
Cobb curves of less than ____ degrees are considered mild and require observation during growth.
25°
76
Bracing for scoliosis is ineffective in managing curves greater than what?
50° --> But might be used to delay surgical interventions by slowing the curve progression Curves at this size require surgical intervention
