Paediatric Flashcards
What is bone age used to assess?
Used to assess skeletal maturity in certain growth/puberty disorders
What are some examples of growth/puberty Disorders?
Bone dysplasia – short stature
Endocrine pathology example hypothyroidism – short stature
How is bone (skeletal) age estimated?
The dates at which carpal bones ossify
DP rest non-dominant hand must be used if it’s being used for estimation of age
When are the carpal bones ossified?
Capitate: 2/12
Hamlet: 3/12
Triquetral: three years
Lunate: four years
Scaphoid: 4–5 years
Trapezium: 4–5 years
Trapezoid: 4–5 years
pisiform: 9–12 years
When do bones in the elbow ossify?
CRITOL
Capitellum: Two months – 2 years
Radiohead: 3–6 years
Internal medial epicondyle: 4–7 years
Trochlea: 8–10 years
Olecranon: 8–10 years
Lateral epicondyle: 10–13 years
Why is it difficult to see fractures in paediatric patients?
Grow centres/growth plates may be confused as a fracture fracture may be confused as a growth plate
How do children’s bones react differently to trauma?
 they bend more - they are more flexible
Give examples of certain fractures that are more common in certain age groups?
Toddlers fracture: 1–2 years
Supracondylar fracture: 4–8 years – distal humerus
Give the two fractures which are notorious in paediatrics:
Buckle (Torus) fracture - Turn like shape on cortex upon – only one side and no splintering
Greenstick fracture - partial fracture – pending appearance
What is the Salter-Harris classification?
It’s a way to easily classify fractures that occur close to the epiphyseal plates
Name the five different types of Salter-Harris classifications:
Type one – physis fracture –
Type two – metaphysis + physis fracture
Type three – epiphysis and physis fracture
Type four – epiphysis and metaphysis fracture
Type five - crush
What does SUFE stand for?
Slipped upper femoral epiphysis
What is a slipped up a femoral epiphysis and how do patients present?
A growth plate injury
patient’s present with a limp, pain and possibly even leg length discrepancy
What is the aetiology of a slipped upper femoral epiphysis?
Unknown - often seen during a period of rapid growth
however obesity is a significant risk factor; history of trauma is in 50% of cases
What is the prevalence of a slipped upper femoral if it is this?
M:F
3:1
M -present later 13 to 16 years
F - Present earlier 11 to 14 years
What percentage of SUFE injuries are bilateral?
60% of SUFE is bilateral
What is the treatment for a slipped open femoral epiphysis?
Surgical opening may lead to physeal closure if so an osteotomy is often required
What is Perthes disease (legg–calve– Perthes)?
It’s avascular necrosis of the femoral head epiphysis
What is the prevalence of Perthes disease?
M: F equals 5:1; peak presentation 5–6 years
What is the incidence of Perthes disease?
Relatively uncommon (5–15 per 100,000 in western world)
