Peds Musculoskeletal/Neuromuscular Dysfunction Flashcards
One of the most difficult aspects of illness in a child is
immobility
contusion
(bruise) is damage to the soft tissue, subcutaneous structures, and muscle
*Escape of blood into tissues causes ecchymosis (black-and-blue discoloration)
Crush injuries
occur when children’s extremities or digits are crushed (finger slammed in the car door).
treatment for contusion
application of cold.
treatment for crush injury
hematomas may require a release of blood by creating a hole at the proximal end of the main with a special cautery device or a heated sterile 18-gauge needle.
dislocation
*Displacement of normal position of opposing bone ends or of bone ends to socket
*Occurs when force of stress on ligament is sufficient to cause displacement
what is the predominant symptom of dislocation
increased pain with active or passive movement of affected extremity
what is the concern with hip dislocation
potential loss of blood supply to head of femur: relocation within 60 minutes provides best chance for prevention of damage to femoral head
sprain
trauma to joint from LIGAMENT partially or completely torn or stretched by force
strain
microscopic tear io MUSCULORTENDINOUS unit
onset: sprain vs strain
sprain: rapid onset of swelling with disability
strain: generally incurred over time
Therapeutic Management ofSoft-Tissue Injuries
RICE AND ICES
RICE
rest, ice(3o mins at a time), compression, elevation
ICES
Ice, Compression, Elevation, Support
what is the most frequently broken bone in childhood
distal forearm
fracture
broken bone
simple or closed fracture
*Does not produce a break in the skin
open or compound fracture
*Fractured bone protrudes through the skin
complicated fracture
Bone fragments have damaged other organs or tissues
comminuted fracture
*Small fragments of bone are broken from fractured shaft and lie in surrounding tissue
growth plate injuries
*Weakest point of long bones: The cartilage growth plate (epiphyseal plate)
may affect future bone growth
growth plate injury treatment
*May include open reduction and internal fixation to prevent growth disturbances
neonatal bone healing period
2-3 weeks
early childhood bone healing period
4 weeks
later childhood bone healing period
6-8 weeks
adolescence bone healing period
8-12 weeks
diagnosis of fracture
*Radiographs (X-ray)
*History taking
*Suspicion of fracture in a young child who refuses to walk or bear weight
goals of fracture management
*Reduction and immobilization
*Restoring function
*Preventing deformity
fracture treatment
reduction and immobilization
splinted or casted to immobilize and protect the injured extremity
Assessment of Fractures: The Six Ps
*Pain and point of tenderness
*Pallor
*Pulselessness
*Paresthesia:
*Paralysis:
*Pressure
cast care
*Elevate casted extremity for first day
*Observe the extremities (fingers/toes) for swelling, discoloration
*Check movement and sensation of fingers/toes
*Do not allow child to put anything inside the cast
*Cool hair dryer can help with itching
Developmental Dysplasia of the Hip
abnormal development of the hip joint found that is congenital
Acetabular dysplasia
the mildest form of DDH, in which there is a delay in acetabular development evidenced by osseous hypoplasia of the acetabular roof that is oblique and shallow. The femoral head remains in the acetabulum.
Sublaxation
the largest percentage of DDH, incomplete dislocation of the hip. The femoral head remains in contact with the acetabulum, but a stretched capsule and ligamentun teres causes the head of the femur to be partially displaced. Pressure on the cartilaginous roof inhibits ossification and produces a flattening of the socket.
Dislocation
the femoral had loses contact with the acetabulum and is displaced posteriorly and superiorly over the fibrocartilaginous rim. The ligamentum teres is elongated and taut.
Clinical Manifestations of DDH: infant
*Hip joint laxity
*Shortened limb on affected side
*Restricted abduction of hip on affected side
*Unequal gluteal folds when infant prone
*Positive Ortolani test result
*Positive Barlow test result
Ortolani test
hip is reduced by abduction
Barlow test
hip is dislocated by adduction
Therapeutic Management of DDH: birth to 6 months
*Pavlik harness for abduction of hip
Therapeutic Management of DDH: 6 to 24 months
*Dislocation unrecognized until child begins to stand and walk; closed reduction and spica cast
Therapeutic Management of DDH: older child
*Operative reduction, tenotomy, osteotomy; correction is very difficult after age 4 years
Tenotomy
surgical cutting of a tendon
Pavlik Harness care
-Skin care
-Check frequently (2-3x/day) for red areas or skin irritation in skin folds and under the straps
-Gently massage healthy skin under the straps once per day to stimulate circulation
-Always place diapers under the straps
-Remove harness only to quickly bathe the infant if allowed by HCP
-Do not adjust the harness
clubfoot
a fixed congenital defect of the ankle and foot
Talipes varus
*Inversion or bending inward
Talipes valgus
*Eversion or bending out
