Pediatric nursing: Orthopedic Disorders


Orthopedic Disorders


Alterations in Musculoskeletal Status


Musculoskeletal Differences in Children





Epiphyseal growth plate present


Bones are growing / heal faster


Bones are more pliable


Periosteum thicker and more active


Abundant blood supply to the bone


The younger the child the faster the healing.



Focused Physical Assessment





Inspect child undressed


Observe child walking


Spinal alignment


ROM


Muscle strength


Reflexes



Assessment





Concerns:


Pain or tenderness


Muscle spasm


Masses


Soft tissue swelling



CoREminder





If an injury has occurred, examine that area last and be gentle when
palpating the injury site



Nursing Alert





A child younger than 1 year who presents with a fracture should be
evaluated for possible physical abuse or an underlying musculoskeletal
disorder that would cause spontaneous bone injury.



Neurovascular Assessment





Pain


Where is it?


Is it reduced by narcotics?


Does the pain become worse when fingers or toes are flexed?



Neurovascular Assessment





Sensation


Can the child feel touch on the affected extremity


Motion


Can the child move fingers or toes below area of injury / nerve injury


Temperature


Is the extremity warm or cool to touch



Neurovascular Assessment





Capillary refill


Sluggish capillary refill may signals poor circulation


Color


Note color of extremity and compare with unaffected limb


Pulses


Assess distal to injury or cast



Neurovascular Impairment





Restriction of circulation and nerve function from injury or immobilizing
device.



Clinical Manifestations





Increased pain


Edema


Decreased movement or sensation


Diminished or absent pulses distal to injury


Patient often described as restless – pain medication do not work – pain
described as deep



Interventions





Assess area distal to injury, cast, splint, traction for adequate
circulation


Release pressure by splitting the cast or loosening restrictive bandage.


Notify physician



Compartment Syndrome





Pain is the hallmark sign, pain out of proportion to the normal clinical
course.


Must be diagnosed immediately or irreversible neurovascular, muscular,
vascular damage occurs that can lead to renal failure and death.



Clinical Manifestations





A combination of signs and symptoms characterize compartment syndrome. The
classic sign of acute compartment syndrome is pain, especially when the muscle
is stretched.


There may also be a tingling or burning sensation (paresthesias) in the
muscle.


A child may report that the foot / hand is "a sleep"


If the area becomes numb or paralysis sets in, cell death has begun and
efforts to lower the pressure in the compartment may not be successful in
restoring function.






Physical Assessment



Frequent pain assessment


If pain med does not work something is wrong


The muscle may feel tight or full.


Measure the affected muscle group and compare with the unaffected side


Pulses below area of injury







Treatment





Prevention



Don’t elevate the affected limb above or below the level of the heart.


Dressings should be removed if CS is suspected.


Casts should be bi-valved in high risk situations.



Assessment





Don’t forget the five P’s


Pain


Paresthesia


Passive stretch


Pressure


Pulse-less-ness



Surgical Management


Nerve Assessment





Important to due on admission from ER or to the unit


Repeat after cast, traction, or surgery done on the extremity



Radius and ulna nerve assessment


Ulnar Nerve Injury


Medial Nerve Injury


Radial Nerve Injury


Peroneal Nerve Distribution


Treatment Modalities





Goals of fracture care:


To regain alignment and length of the bony fragments


To retain alignment and length


To restore function of the injured part



Traction





Realign bone fragments


Provide rest


Prevent or improve deformity


Pre or post operative positioning


Reduce muscle spasm


immobilization



Fractures


Fractures


Salter Fracture I and II


Salter Fracture III, IV and V


Salter-Harris Classification


Bucks Traction


Principles of Traction





Counter traction with weights


Make sure all ropes and pulleys are aligned and weights are hanging freely


Do not remove weights unless instructed to do so


Traction must be applied at all times



Bryants Traction


Bryants Traction





Used for child under 3 yrs


Hip dysplasia / fractured femur


Buttocks do not rest on mattress


Assess neurovascular and restriction by ace bandages – compartment syndrome



Skeletal Traction


External Fixator


External Fixation


External Fixator


Pin Care





Provide pin care as ordered. Cleanse area around pin with normal saline or
half-strength hydrogen peroxide.


Have parent / caretaker demonstrate pin care before discharge



External Fixator


External Fixator


Plates and Pins


Post-operative Care





Assess color, sensation, cap refill, movement, pain, and pulses


Circle any drainage noted on cast or dressing.


Pain control


Edema = ice to area


Pulmonary function = C&DB



Pulmonary Embolism





A complication of a fractured leg is a pulmonary embolism. Fat escapes the
marrow when the bone is fractured and can travel through the blood stream and
become lodged in small vessels like the arterioles and capillaries of the
lung.


Primary symptom is shortness of breath and chest pain.



Interventions





Place patient in high fowlers


Administer oxygen


Call MD


Chest x-ray


Outcomes are better for a health person; poorer for person with
pre-existing lung problems.



Orthopedic Disorders





Congenital


Acquired / trauma


Infectious



Tales Equinovarus


Tales Equinovarus





Club Foot


1 to 2 per 1000


Males more affected


Involves both the bony structures and soft tissue.


The entire foot is pointing downward.



Interventions



Manipulation and serial casting immediately


Surgery is performed between 4 to 12 months if full correction is not
achieved with casting



Nursing Diagnosis





Impaired physical mobility related to cast wear


Altered parenting related to emotional reaction following birth of child
with physical defect


Risk for impaired skin integrity related to cast wear.


Knowledge deficit: cast care and home care



Metatarsus Adductus





Most common foot deformity


2 per 1000


Result of intrauterine positioning


Forefoot is abducted and in varus, giving the foot a kidney bean shape.



Metatarsus Adductus


Dysplasia of the Hip





Abnormality in the development of the proximal femur, acetabulum, or both.


Girls affected 6:1


Familial history


Breech presentation


Maternal hormones

Risk for impaired skin integrity related to pressure from casts or braces


Altered skin perfusion due to casts or braces


Risk for altered growth and development due to limited mobility



Harness


Osteogenesis Imperfecta


Osteogenesis Imperfecta





Genetic disorder


Caused by a genetic defect that affects the body’s production of collagen


Collagen is the major protein of the body’s connective tissue


Less than normal or poor collagen leads to weak bones that fracture easy



Osteogenesis Imperfecta





Often called "brittle bone disease"


Characteristics





Demineralization, cortical thinning


Multiple fractures with pseudoarthrosis


Exuberant callus formation


Blue sclera


Wide sutures


Pre-senile deafness

Common age for child abuse.


Often present as suspected child abuse



3-month-old with OI


Type II



Autosomal Recessive


Pre- or perinatal death


Pulmonary hypoplasia



Fetus with severe OI


New Born with OI


Nursing Diagnosis





Risk of injury related to disease process


Risk for altered growth and development


Knowledge deficit: disease process and care of child



CaReminder





Signs of a fracture, especially in an infant, are important items to teach
caregivers. In a baby, these signs are general symptoms, such as fever,
irritability, and refusal to eat.


Bowden, 1998



Cerebral Palsy





Group of disorders of movement and posture





Prenatal causes = 44%



Labor and delivery = 19%


Perinatal = 8%


Childhood = 5%




Cerebral Palsy


Assessment





Developmental surveillance is key


Diagnoses often made when child is 6 to 12 months of age


Physical exam:





Range of motion


Evaluation of muscle strength and tone


Presence of abnormal movement or contractures




caReminder





Reflexes that persist beyond the expected age of disappearance (e.g., tonic
neck reflex) or absence of expected reflexes are highly suggestive of CP.


Bowden, 1998



Clinical Manifestations





Hypotonia or Hypertonia


Contractures


Scoliosis


Seizures


Mental Retardation


Visual, learning and hearing disorders


Osteoporosis – long term due to lack of movement



Team Management

Limping


Limited hip motion especially internal rotation and abduction is classic
sign



Management





Goal of care is to: Keep femoral head in the hip joint





Traction


Anti-inflammatory


Physical therapy




Osgood-Schlatters


Assessment





Tip: Asking the child to squat or extend his or her knee against resistance
usually elicits pain and is a good indicator of Osgood-Schlatter Disease.



Osgood-Schlatters





Due to repetitive motion


Affects children 10 to 14 years old


Males 3:1


Diagnosis is based on clinical signs and symptoms





Pain, heat, tenderness, and local swelling




Management

Clinical Manifestations





Pain is not a normal finding


for idiopathic scoliosis


Often present with uneven hemline


Unequal scapula


Unequal hips



Screening


Screening


Mild Scoliosis


Severe Scoliosis


Assessment





Alert: If pain is a reported symptom of the child’s scoliosis, it should be
investigated immediately. Pain is not a normal finding for idiopathic
scoliosis, and the presence of this symptom could be signaling an underlying
condition such as tumor of the spinal cord.



Bracing


Moderate Scoliosis


Scoliosis


Post-operative Care





Pain management


Chest tube in many cases


Turn, cough, and deep breath


Log-roll



Nursing Diagnoses

Bone scan – most definitive test for osteomyelitis



X-Ray


Osteomyelitis


Management





Culture of the blood


Aspiration at site of infection


Intravenous antibiotics x 4 weeks


PO antibiotics if ESR rate going down


Monitor ESR





Decrease in levels indicates improvement




Goals of Care





To maintain integrity of infected joint / joints



Septic Arthritis





Infection within a joint or synovial membrane


Infection transmitted by:





Bloodstream


Penetrating wound


Foreign body in joint




Septic Arthritis of Hip





Difficulty walking and fever


Diagnosis: x-ray, aspirate fluid from joint, ESR



Septic Hip


Diagnostic Tests





Erythrocyte Sedimentation Rate





ESR


Used as a gauge for determining the progress of an inflammatory disease.


Rises within 24 hours after onset of symptoms.


Men: 0 - 15 mm./hr


Women: 0 – 20 mm./hr


Children: 0 – 10 mm./hr





C-Reactive Protein





During the course of an inflammatory process an abnormal specific protein,
CRP, appears in the blood.


The presence of the protein can be detected within 6 hours of triggering
stimulus.


More sensitive than ESR / more expensive



Joint Space Fluid


Management





Administration of antibiotics for 4 to 6 weeks.


Oral antibiotics have been found to be effective if serum bactericidal
levels are adequate.


Fever control


Ibuprofen for anti-inflammatory effect



Goals of Care





Maintain integrity of affected joint



Juvenile Rheumatoid Arthritis





Chronic inflammatory condition of the joints and surrounding tissues.


Often triggered by a viral illness


1 in 1000 children will develop JRA


Higher incidence in girls



Clinical Manifestations





Swelling or effusion of one or more joints


Limited ROM


Warmth


Tenderness


Pain with movement



Diagnostic Evaluation





Elevated ESR / erythrocyte sedimentation rate


+ genetic marker / HLA b27


+ RF 9 antinuclear antibodies


Bone scan


MRI


Arthroscopic exam



Goals of Therapy





To prevent deformities


To keep discomfort to a minimum


To preserve ability to do ADL



Management





ASA


NASAIDS around the clock


Immunosuppressive drugs: azulvadine


Enbrel: new class of drugs to treat JRA





Attacks a specific aspect of the immune response




ASA Therapy





Alert: The use of aspirin has been highly associated with the development
of Reye’s syndrome in children who have had chickenpox or flu. Because aspirin
may be an an ongoing p art of the regimen of the arthritic child, parents
should be warned of the relationship between viral illnesses an aspirin, and
be taught the symptoms of Reye’s syndrome.



Management





Physical therapy


Exercise program


Monitor ESR levels


Regular eye exams: Iriditis





Iriditis





Intraocular inflammation of iris and ciliary body


2% to 21% in children with arthritis


Highest incidence in children with multi joint involvement disease.





Iriditis
