rognosisrognosis Most children with IJO experience a
.complete recovery of bone tissueAlthough growth may be somewhat
impaired during the acute phase of
,the disorder normal growth resumes - and catch up growth often occurs
. ,afterward Unfortunately in some
,cases IJO can result in permanentdisability such as curvature of the( )upper spine kyphoscoliosis or a
collapse of the rib cage

cquisition of peak bonecquisition of peak bonemassass The rate of bone mass acquisition
tends to mirror height velocity and.is greatest during puberty Bone
mass continues to accumulate until, ,the late teens early twenties at( )which time peak bone mass PBM is
achieved
Women tend to reach PBM sooner than
men and blacks sooner than whites[ ]. , %7 9 On average 90 of PBM isacquired by the age of 19 years

MD in pediatricsMD in pediatrics WHO criteria for diagnosing
osteoporosis in adults should not beapplied to children
-The use of T scores is not applicablebecause children have not yetreached PBM
, Instead a child s BMD must be-converted to a Z score by comparison
.to pediatric normative data Theterm low bone density for
chronologic age should be used if- - .the Z score is below 2 0 SD
