diastrophic dwarfism
short-limbed dwarfism ("diastrophic" means twisted, thus scoliosis)
x-ray features:
- short flared metaphyses with flattened epiphyses in tubular bones
of extremities
- equinovarus deformity of feet -- major joints subluxed
- spine: kyphoscoliosis with gradual decrease in interpediculate
distance toward caudal end of L-spine
- hands
- "hitch-hiker's thumb" - widely abducted
- hypoplastic first metacarpal
- other metacarpals too broad, esp. at growing end
- carpal bones with too many centers ossified
