  <Scoliosis>

 

1. Def. : lateral deviation & curvature of spine usually with vertebral body rotation

* structural scoliosis vs. nonstructural scoliosis

3. Classification of scoiosis

Idiopathic : infantile (1-3 yrs old)

juvenile (4-9 yrs old)

adolescent (over 10 yrs old)

Congenital : failure of formation

failure of segmentation

Neuromuscular : neuropathic

myopathic

Scoliosis with neurofibromatosis

Miscellaneous : tumor, infection, D.A. etc

<1> Iiopathic scoliosis

a. most common in scoliosis

b. 3 type : infantile, juvenile, adolescent

c. Adolescent type : over 10 yrs old, female, Rt thoracic curve is common

d. Sx : slow progression, shoulder or pelvis elevated, scapula or buttock prominent

e. Dx : foreward bending -> prominent hump, standing x-ray

f. Tx : close observation

brace (TLSO, Milwakee brace)

corrective op.

<2> Congenital scoliosis

a. classification : Formation failure -> wedge vert.

Segmentation failure -> unilateral unsegmented bar

block vert.

b. Associated cong. anomaly ; U-T anomaly in 20 %, congenital heart disease in 15-20 %, intraspinal anomaly(syringomyelia, thetered cord, diastematomyelia) in 10 %
