Unilateral Bar:

Segmented Vertebrae:
- Discussion:
- many pts have mild curves that are stable for years and then suddenly
become severe when the adolescent growth spurt begins;
- approx 75% of pts w/
Congenital Scoliosis will show progression,
& approx 50% will progress significantly and require treatment;
- two or more
hemivertebrae on the same side are likely to result in
scoliosis that progresses as the child grows.
- when 2
hemivertebrae exist on opposite sides, scoliosis
may be slight.
- failure of development of the anterior portion of one or more
vertebrae results in
Kyphosis.
-
Prognosis for progression of
Congenital Scoliosis depends on type of
congenital deformity present, its location in the spine, & age of pt
at presentation.
-
worst prognosis:
Unilateral Bar w/ contralateral
hemivertebra;

best prognosis :
block

- progressive spinal deformity is rarely produced by block vertebrae,
which are 2nd to bilateral failure of segmentation;
