- Discussion:
-
scoliosis is present in > 20% pts who have symptomatic spondylolisthesis
but in only 13 per cent of those who have spondylolysis;
- incidence of scoliosis is higher in pts w/
dysplastic spondylolisthesis than
in those who have
isthmic spondylolisthesis;
- Olisthetic scoliosis:
- scoliosis usually is not structural & is second to lumbar muscle spasm;
- curves will resolve w/ recumbency and relief of symptoms;
- olisthetic scoliosis is a torsional lumbar curve, w/ asymmetrical
displacement & rotation that begins at the spondylolytic defect;
- about two-thirds of lumbar and olisthetic curves can be expected to
resolve after surgical stabilization of the spondylolisthesis, and
those that do not improve seldom progress;
- Idiopathic Scoliosis:
- idiopathic curves are confined to
thoracic or
thoracolumbar portion of
spine and develop in about 1/3 of patients who have
Spondylolisthesis;
- the question in these patients is whether the fusion should be carried down to S1;
