Which of the following is least associated which congenital scoliosis (AIIMS Nov 2012)
Block vertebrae Ref: Campbells 11th edition
Classification of Congenital Scoliosis
Partial failure of formation (wedge vertebra)
Complete failure of formation (hemivertebra)
Failure of segmentation
Unilateral failure of segmentation (unilateral unsegmented bar)
Bilateral failure of segmentation (block vertebra)
a. The skin of the back should be carefully examined for signs such as hair patches, lipomata, dimples, and scars, which may indicate an underlying anomalous vertebra. The neurological evaluation should be thorough.
b. Many children with congenital scoliosis have other anomalies. 18% of these patients can have urological anomalies, congenital heart disease is seen in 7% of these patients.
c. Unsegmented bar has more severe progression than hemivertebra. Least severe progression is block vertebra.
d. Dorsolumbar scoliosis is more severe than lower thoracic which is more severe than upper thoracic
e. Because 75% of congenital curves are progressive and only 5% to 10% can be treated with bracing, surgery remains the fundamental treatment.
