Orthopaedics in Children Flashcards
common orthopaedic presentations in children
fractures - salter harris classification
osteochondritis - perthes
SCFE
Scoliosis
common musculoskeletal and sports presentation
apophyseal inflammation and avulsion
hip complaints e.g FAIS
What outcome measure may be used to examine the child’s musculoskeletal system
pediatric gait, arms, legs, spine screen
screening questions - ask about pain or stiffness across joints muscle back, ask about difficulty with functional tasks e.g going up/down stairs or dressing yourself
gait assessment - do they walk in tip toes/heels
what should be assessed before you approach the child for an orthopaedics physio session
- Review notes
- PEWS*
- Talk to Nursing Staff
- Has the child had pain relief
- Has the child had any anxiety/fear
- Is there a parent present
- Communication – is the child likely to be impulsive
- Are there any attachments IVs etc
what physical differences are between between children and adults
articular cartilage thicker in children
junction b/w epiphyseal plate and metaphysis is vulnerable to shear forces and disruption in children
relatively weak apophyses
metaphysis of long bones in kids resilient and elastic - prone to greenstick fracture
growth temporarily impacts co-ordination
classification salter harris fracture
fracture involving physis/growth plate
describe a type 1 salter harris fracture
slipped - complete physeal break comprised of 2 components
2 components are slightly displaced
describe a type 2 salter harris fracture
physeal fracture extends to Metaphysis = produce chip fracture
describe a type 3 salter harris fracture
a physeal fracture that extends to the articular epiphysis
describe a type 4 salter harris fracture
a complete physeal fracture that includes metaphysis and ephiphysis
describe a type 4 salter harris fracture
a complete compression physeal fracture of the growth plate
what are the clinical implications of a type 1 salter harris fracture
Most common (75%), uncomplicated and 2-3 week healing time
what are the clinical implications of a type 2 salter harris fracture
- Triangular fragment can be reduced normally and cast applied
- Sometimes open reduction needed
what are the clinical implications of a type 3 salter harris fracture
- Mostly seen in older children when growth plates have begun to close
- Most require ORIF
- Can form a pyseal bar leading to assymetric growth
what are the clinical implications of a type 4 salter harris fracture
- Fracture through all elements – ORIF often
- If growth hs ceassed then ok
- If not, careful monitoring needed to ensure no physeal bar/grwoth disturbance
what are the clinical implications of a type 5 salter harris fracture
- Often missed, spotted when growth has be impacted.
SCFE what is it?
Slipped upper femoral epiphysis/ Slipped capital femoral epiphysis
damage to the growth plate of the femur
resulting in the head of the femur to slip and become misaligned with the remaining femur
what is a risk factor of slipped capital femoral epiphysis
obesity
explain the epidemiology of slipped capital femoral epiphysis
Bilateral in ~ 20% of cases
* Affects boys more than girls
* Affects boys later (10-17) than girls (8-15
what are the presentations of slipped capital femoral epiphysis
- Antalgic gait
- Pain in groin thigh or knee
- If you flex the hip it will externally rotate and abduct
- Advise to restrict weight bearing
potential complications of slipped capital femoral epiphysis
Osteonecrosis (risk up to 50% in untreated SUFE)
Chondrolysis (risk 7%)
Osteoarthritis
Femoral acetabular impingement - severe
what is osteochondritis
joint disorder in which a segment of bone and cartilage starts to separate from the rest of the bone after repeated stress or trauma.
what is perthes disease
- Idiopathic avascular necrosis of the head of the femur
- Ostechondrosis
what are risk factors of perthes disease
transient synovitis*, paternal smoking/passive smoking in pregnancy,
thrombophilia,
low birthweight,
family history
where in the body does osteochondritis dessicans typically occur
medial femoral condyle
capitellum
talar dome
what is the typical presentation of perthes disease
- Pain and limp
- Pain in groin, thigh or knee
- Pain increases with hip movement
- Decreased hip medial rotation and abduction
- Thigh muscle atrophy
what are the possible consequences of perthes disease not being appropriately addressed
can cause leg length discrepancy
may need THR long term
what long surgical interventions available for perthes disease
- Pain relief with anti-inflammatories
- Observation
- Protected weight bearing
- Splinting/casting - Petrie
- 4-6 weeks
- Bed rest with traction
