Bad posture, kyphosis, back pain in teen
Dx
Tx
Scheuermann dz
NSAID, pt, obs
What is sprengel deformity?
looks like torticollis, but its due to failure of scapula to descend and affected side is broader and shorter
Congenital elevation of the scapula
Barlow vs Ortolani
Which side usu worse?
Barlow: adduction w/ downward pressure
Ortolani: attempt to relocate
Left worse

chronic knee pain that locks and swells in adolescent?
Dx and tx?
osteochondritis dissecans
adolescent boys: immobilization, eventual removal of fragments if not improved
pain just below knee in adolescent athlete?
Osgood Schlatter
When to observe for scoliosis?
if curve < 25degrees
When to brace for scoliosis
if more than 2 yrs growth expected, and curve is 25-40
When surgery is needed for scoliosis
curve >40-45
Dx w/ swelling of bone shafts only in cortical bone, with progressive cortical thickening. DDX?
Caffey Dz.
DDX: NAT, but there is no periosteal involvement

Dx?
Tx?
how often both feet?
club foot, tx: stretch, cast serially (Ponsetti 4-5 wks), surgical release in late 1st year.
50% bilateral
genu varus ok until when, then think what?
bow legged okay until age 2 and if bilateral.
If not, think rickets, Blounts disease
Blount’s disease
What is it, what are the types
pathology of proximal tibial physis/epiphysis
Infantile: African Americans, no tx needed
Adolescent: obese African American: need tx
absent radius (thumb issues): name 3
- TAR: thrombocytopenia, absent radius
- Fanconi ANEMIA: fan blade cuts it off
- VATER: R: absent radius
two syndromes to think of w/ high arches?
- Friedreich (Fried arch)
2. Hurlers
Flat feet, pes planus tx:
usu no intervention
Tx for salter 1 frx
2-3 weeks cast
Type 2 SH fracture?
Tx
metaphysis splits w/ some physis (the dogbone part: meta)
closed reduction 3-6 wk cast
Type 3 SH?
Tx
through growth plate and epiphysis, may need open reduct. WORSE than 2 b/c goes into joint space…
the deal with fat pads on XR?
anterior fat pad: all right
posterior fat pad: poor…fracture?
snuff box pain?
scaphoid bone fracture even if negative XR
hip extended and externally rotated in obese teen male.
How to dx?
Tx?
SCFE
Frog leg/AP XR
Tx: immobilize, no wt bearing, may need pins/bone grafts

< 16 yr, at least 6 wks in at least 1 joint
Labs abnl in JRA?

When is JRA likely to have RF+
older pts w/ polyarthritis JRA usually with more serious issues and nodules, like adult version

+/- systemic disease?
unlikely
Oligo JRA / Pauci
- def
