25
Osteogenesis Imperfecta
* defects in type 1 collagen
* increased bone turnover
* genetic cause
* often short stature, poor tooth formation, hearing loss, blue sclera, translucent skin, triangle face
* osteoporosis, ligamentous laxity, scoliosis, propensity for fractures
* fragility limits play and ADL opportunities, mobility limitations
26
Scurvy
* decreased thickening of bone cortex and epiphyseal plates
* decreased bone available for calcification
* caused by insufficiency of vitamin C
* fragile bones, can fracture. Limits options for play
27
Rickets
* deficiency interferes with bone calcification
* caused by deficiency of vitamin D
* long bones bend under body weight
* may interfere with play, ADLs
28
Fractures
* peak for typically developing, health children in early adolescence
* bone turnover is high at this age
* mineralization may lag behind height, weight growth
29
Risk of subsequent fracture increases ____ after first fx
* 2-3x
* increases w/decreased calcium intake, first fx before 5 yo, and obesity
30
Epiphyseal Fracture
* fracture through growth plate
* may cause growth arrest
* about 20% of peds fractures
31
Salter Harris Classification
* determines extent of growth plate involvement
* Type 2 is the most common
* type 5 has poor prognosis
* type 1-2 = does not completely cross epiphysis
* type 3-4 = crosses epiphyseal border
* type 5 = crushing injury
32
Growth arrest
* complete may lead to significant limb length inequality
* asymmetrical may result in angular deformities if portion of bone keeps growing
usually happens in type 3-4
33
Greenstick Fracture
* occur in long bones when force breaks the cortex on side of impact and bends the other
* causes angular deformity
* refer to ortho physician
34
Treatment of fracture depends on
extent of involvement
follow WB precautions, and advise/education with AD as necessary
35
Nondisplaced/displaced treatment
Non = typically treated with cast
Displaced = closed or open reduction
