MISCONCEPTIONS
surgery is a last resort
weakness doesn’t improve
more trouble in the future
these get beDer by themselves

INDICATIONS FOR EARLIER SURGERY
HISTORY • intolerable pain
EXAMINATION • functional weakness
INVESTIGATIONS • MRI shows huge herniation

EXAMINATION • no positive supporting findings
INVESTIGATIONS • MRI shows small herniation

SPINAL STENOSIS
narrowing of the spinal canal with nerve compression What is it ?
leg pain and neurogenic claudication
What does it cause ?
![Page 19: Operative treatment for common back conditions](https://reader033.vdocuments.mx/reader033/viewer/2022051705/58832bd71a28abe2758b788b/html5/thumbnails/19.jpg)
SPINAL STENOSIS
when symptoms severe When do we operate ?
SURGERY IN THE FORM OF DECOMPRESSION
nonoperative treatment unsuccessful
Why do we operate ?

SPINAL STENOSIS
stenosis with instability • degenerative spondylolisthesis • degenerative scoliosis
When do we add fusion ?
SPONDYLOLISTHESIS SCOLIOSIS
![Page 23: Operative treatment for common back conditions](https://reader033.vdocuments.mx/reader033/viewer/2022051705/58832bd71a28abe2758b788b/html5/thumbnails/23.jpg)
Aetiology • due to degeneration of
facet joint • facet joint stability fails
and L4 slips forward on L5 • leads to spinal stenosis
DEGENERATIVE SPONDYLOLISTHESIS

DEGENERATIVE SCOLIOSIS
Aetiology • due to asymmetric
degeneration of disc and facet joint
• vertebral tilt leads to spinal deformity and
accelerated degeneration • associated spinal stenosis
