TLO 2.8 Musculoskeletal Child Flashcards

1
Q

What does the skeletal system do?

A

Provides structure and support
Protects vital organs
Provides movement
Storage space: blood cell production, regulates mineral and hormonal imbalances

**Bone structural disorders require follow up until child reaches skeletal maturity

Q

Pediatric musculoskeletal difference

A

Skull sutures don’t fuse until 12-18 months
Muscle tissue almost completely developed at birth
Soft tissues are resilient making dislocation and sprains less common
Infants’ bones only 65% ossified at 8 months age
Fractures in <1 year child, uncommon, consider abuse

Q

What is a sprain and strains?

A

Sprains:
Joint trauma where a ligament is stretched or partially torn
Strains:
Known as pulls, tears ruptures, result from excessive stretch of muscle
**Both manifest as:
pain, swelling, localized tenderness, limited ROM, poor weight bearing, pop sound (sprain)

Q

Management of sprains and strains

A

Primary goal is to reduce swelling and prevent further injury
RICE: rest, ice, compression, elevation
ICES: ice, compression, elevation, support
**swelling inhibits healing by keeping ligament ends separated. First 6-12 hours most important in controlling swelling and reducing muscle damage. Elevate above level of heart

Maintain nutritional status, high calories, protein, frequent small meals

28
Q

Scoliosis, what is it?

A

Lateral deviation/curvature of spine >10 degree
Curvature causes rotation of vertebral bodies of spine
Worsening curvature leads to:
Rib cage deformities= compromised respirator function
Distortion of intrathoracic and abdominal organs that does not affect organ function generally

Visible curvature of spine
Rib hump when child bends forward
Asymmetric rib cage
Uneven shoulder or pelvic heights
Scapular prominence
Hip and leg length discrepancy
30
Q

A

Curves <25 degree require long term monitoring

Curves >25 degree require brace treatment

31
Q

Scoliosis nursing interventions for brace treatment

A

Doesn’t correct curve but prevents progression
Wear fitted t-shirt under brace to protect skin
Remove for bathing, swimming, exercise only
Re check size as child grows
Analgesics for discomfort

32
Q

Scoliosis surgical intervention

A

Recommended for curvatures reaching 40-50 degrees
Goal is to reduce size of curvature and obtain solid fusion using metal rod and bone grafts (ribs, iliac crest, vertebral body)
May not completely correct spine but stabilized spine that centers head, shoulders and truck over the pelvis

33
Q

Scoliosis surgical interventions/complications

A

Significant blood loss common r/t vascular nature of vertebrae and spinal column
Injury to spinal cord
Infection

34
Q

Scoliosis surgical pre op care and teaching

A

Routine teaching (resp, circulation, pain)
Remain flat/log rolling technique
Express feelings/anxiety
PCA, foley, chest tube (if anterior approach)

35
Q

Scoliosis surgical post op care

A

Neurovascular checks q 2hr for 48 hr then q 4hr
Pain management
Teach log roll, turn q 2hr
Ambulate post op day 2-3 and d/c day 4-5
Respiratory status, inspirex, cough and deep breathing
Encourage self care activities as appropriate
Bed flat unplug bed controls
Bowel function
Wound healing/sit

36
Q

Hip Dysplasia, what is it?

A

Developmental dysplasia of the hip (DDP) described variety of disorders that present different ages and forms
-if present at birth called congenital
-develops after birth called developmental
Etiology: unknown
Instability of hip joint occur as result of laxity of ligaments holding head of femur in acetabulum

37
Q

Hip dysplasia risk factors

A 
First bone child
Female
Breech position
Low levels amniotic fluid in utero
African and Chinese decent low incidences
Native American high incidences
38
Q

Hip dysplasia manifestations, older infants

A

Older infants:
asymmetry of gluteal folds
limited ROM in affected hop
abduction present when supine with knees and hips flexed
femur on affected side appears shorter
s/s range from lax ligaments to contractures and stiffness in affected hip

39
Q

Hip dysplasia manifestations, older child

A 
Older child:
Any abnormalities in gait need evaluation
Child may:
Limp
Toe walking or waddling gait
40
Q

Hip dysplasia management

A

Pavlick harness: provides hip flexion, abduction, external rotation

Bryant’s traction: releases muscles and tendons to manipulate hip joint

Closed or open hip reduction surgery

Spica cast post op immobilization

41
Q

Hip dysplasia teaching

A

Don’t straighten legs or swaddle together
No car seats that restrict hip position
Check skin under harness daily
Check neurovascular status on feet
Cast care, management elimination, keep dry
Adapt clothing for weather
Never leave child unattended, kids still move, safety issue
Change positions q 2 hr
How to apply Pavlick Harness and only remove as provider order
Protect skin, use onesie

42
Q

Legg-Calve Perthes disease, what is it?

A

Cause is unknown but accepted as growth disorder
Involves femoral head progresses through 5 stages over 1-2 year period
-epiphysis shows ischemia
-reduction in size and increased femoral head density
-bone weakens and dies causing femoral head collapse
-avascular bone reabsorbed and begin to form new bone
-femoral head reform result in final healing
**disease is self limiting (runs its course generally)

43
Q

Legg-Calve Perthes disease manifestations

A

Pain in hip worsens with movement
Shortening of affected side, indicates collapsing of femoral head
Muscle wasting of thigh and buttocks
Unilateral hip involvement
Permanent deformity if healing process is incomplete (femoral head protrudes outside acetabulum)

44
Q

Legg-Calve Perthes disease diagnosis

A

X-ray
Bone scan or MRI can revel necrosis and irregularity of femoral head
**more common in boys than girls ages 4-9 year

45
Q

Legg-Calve Perthes management

A

Initial treatment:
anti-inflammatory meds
ROM exercises and bedrest

After 7-10 days if still unable to abduct hip:
traction or abduction braces
surgery to place femur securely into acetabulum

46
Q

Clubfoot/talipes equinovarus manifestations

A

Plantar flexed foot with inverted heel and adducted forefoot
unilateral or bilateral defect
cannot be manipulated into neutral position
readily apparent at birth

47
Q

Clubfoot diagnostics and therapeutic management

A

Ultrasounds prenatally

Therapeutic:
stared ASAP
serial stretching, manipulation and casting
surgery
recurrence is common
f/u until skeletal maturity
48
Q

Clubfoot nursing care

A 
Same as child with cast
Clear parental instructions
-bathing
-time feeding with manipulations to allow distraction
-encourage normal development
49
Q

Muscular Dystrophy, what is it?

A

Progressive degenerative diseases that affect muscle cells or specific muscle groups causing weakness and atrophy.

  • *most identified early childhood
  • *includes >30 types but Duchenne MD is most common. affects limb and trunk muscles first
50
Q

Muscular Dystrophy pathophysiology

A

Muscle fibers leak creatinine kinase and take on excess Ca+ causing more damage
Muscles degenerate and replace with fat and connective tissue
Muscle death causes weakness and wasting

51
Q

Muscular Dystrophy manifestations

A

Progressive, symmetric muscle wasting and weakness without loss of sensation
Symptoms become acute age 3-7 (hypertrophied muscles)
Waddling wide based gait, can’t climb stairs
Gowers sign, use hands to walk up legs to stand erect
Walking ability lost age 9-12 years
Shortened life span r/t affect on GI, brain, cardio
Cardiopulmonary complications common cause of death

52
Q

Muscular Dystrophy diagnosis

A

EMG and muscle biopsy
Genetic screening
Physical findings
Serum creatinine kinase (CK) elevated early stages of disease then decrease as muscle decreases

53
Q

Muscular Dystrophy therapeutic management

A

Goal to maintain ambulation and independence as long as possible
No effective treatment
Manage symptoms
Prevent contractures: ROM, bracing, PT, weight control
