TLO 2.8 Musculoskeletal Child Flashcards
What does the skeletal system do?
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
Pediatric musculoskeletal difference
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
Diagnostic tests
X-ray Bone scan MRI CT scan **non-invasive
Diagnostic tests, X-ray purpose, viewing, nursing
Purpose: detect abnormalities or determine bone age View: Air looks black Fat looks dark grey Water looks light grey Bone looks whitish Nursing: noninvasive not generally NPO place in gown assist young children with proper positioning
Diagnostic test, bone scan, purpose, nursing
Purpose (investigates): trauma, early stress fractures, tumors, infections (diskitis, osteomyelitis)
Radioactive material given IV and scan occurs 3-4 hours later
Nursing:
encourage fluids 2-4 hr prior helps rid radioactive material
void before scan, improves pelvic bone visualization
young children may need sedation
Diagnostic test, MRI, purpose, nursing
Purpose:
Clearly define organ structures
Show changes in soft tissue (edema, infarcts)
Magnet and radio waves create energy field that’s translated to an image
Nursing:
No NPO
Ensure no metal on pt
Is loud, can take 1 hr
Assess claustrophobia
Must remain still (kids might need sedation, NPO is sedation)
Diagnostic test, CT scan, purpose, nursing
Purpose; Visualize boney and soft tissue details Has more radiation exposure X-ray beams scan in successive layers and can be shown in 3D if needed With or without contrasts Nursing: Not NPO Scary for children, sounds like loud washing machine Place in gown NPO if sedation Assess allergies for dye
What is a sprain and strains?
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)
Dislocation, what is it?
Force of stress on the ligament results in displacement of the bone from it's socket Pain and joint deformity results Most common sites: phalanges elbow hip shoulders **ligaments bind bones together
Management of sprains and strains
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
Sprains and strains, nursing considerations
Analgesics: acetaminophen ibuprofen (controls pain and swelling) Distraction and play can help with pain Healing time depends on extent of injury Weigh bearing gradually increased as pain decreases
Common causes of fractures
Accidental trauma; falls, MVA
Non accidental trauma; child abuse
Pathologic conditions; osteogenesis imperfecta, tumors cysts
**children heal faster than adults
**weakest point of long bones is cartilage growth plat or epiphyseal plate
Types of fractures
Greenstick: partial break on one side of bone while bone bows on other side, common in forearm
Spiral: twisted break/circular break seen in child abuse
Oblique: diagonal break
Transverse: break occurs at right angle
Comminuted: bones splintered into pieces rare in kids
Compound: bone exposed through skin
Manifestations for fractures in children
Pain/tenderness at site Decreased ROM/immobility Deformity Swelling Ecchymosis, muscle spasm Inability to bear weight Crepitus Erythema
Diagnostic test for fractures
X-ray: both side view to compare
**distal forearm and clavicle common fracture sites
Fracture management, reduction, retention
Goal: maintain function without affecting growth
Reduction= align
Repositioning of the bone into normal alignment, open- surgically inserting devise (rod, pins)
Retention= hold
Application of a device to maintain alignment until healing occurs, splints, casts, traction, external fixation
Immobilization of fractures
Splints
Casts
Traction: manual, skin, skeletal
External fixation
Purpose of traction?
Reduce muscle spasm
Position distal and proximal bone ends in realignment
Immobilize the fracture site until realignment has been achieved and healing has taken place to permit casting or surgical fixation
Skin traction, what is it?
Noninvasive and well tolerated
Best for kids <15kg or <3 years of age
Applied to pelvis, spine, extremities (long bones)
Use external devices (foam, straps, bandages) applied to skin attached to pulleys and weights
Not appropriate if skin infections, open wounds, extensive tissue damage, abnormal sensations in extremities
Skeletal traction, what is it?
Exerts greater force than skin traction
Tolerated for longer periods of time
Maintains alignment of bony fragments and assists in proper healing
Traction maintained by metal device inserted into bone
Osteomyelitis most serious complication
External fixation device, what is it?
Used to treat:
Complex fractures
Length bones
Correct angular deformities involving bones and soft tissue
Allows for periodic changes in alignment with external device with pines inserted into bone
Infection is risk r/t pin sites, 50% develop problems
