본문내용

Associated conditions
: Congenital scoliosis
Down syndrome
Generalized ligamentous laxity
C0-C1 instability 60 %
C1-C2 instability 15%
Progressive instability most common in males > 10 yr
Surgical complications common
Graft resorption
Instability above, below fusion
Immobilize 6 mo post-op

Congenital scoliosis
Caused by disturbances in vertebral development during the sixth to eighth week of embryologic development

Morquio`s syndrome
Error of mucopolysaccharide metabolism with excretion of keratan sulfate in urine
Skeletal defects with short stature
Severe deformity of spine and thorax
Long bones with irregular epiphyses shafts of normal length
Enlarged joint
Flaccid ligaments
Waddling gait
AR inheritance
- type IV A mucopolysaccharidosis : absence of galactose-1-sulfatase
- type IV B : deficiency of a beta-galactosidase.
