Outline
Urgent Vs. Elective.
Diagnosis of four common spine disorders
– Spinal Stenosis (with and without instability)
– Disk degeneration
– Herniated Disc
– Arthritis (spondylosis)
Treatment of common spine disorders
– Nonsurgical Vs. Surgical

Urgent Vs. Electives
Urgent
– Infection
– Tumor
– Trauma
– Caudal equina
Electives
– Everything else.

Stenosis with
Spondylolisthesis Derivation from Greek
– Spondylos: “vertebra”
– Olisthein: “to slip”
Myerding Grading
System
– Grade 1 25%
– Grade 2 50%
– Grade 3 75%
– Grade 4 100%

Pathophysiology
Narrowing cauda
equina to 63% of
normal raises
intrathecal pressure to
50 mmHg
capillary flow
electrical conduction
edema within &
along nerve roots

any activities
Sitting intolerance
More pain with
flexion than extension

4. Arthritis of the Spine
![Page 22: Common Spine Disorders Diagnosis and Treatment...MRI-HNP Treat patient not x-ray ! 67Asymptomatic volunteers: – MRI + Herniated disc • 60 yo = 36% • >80](https://reader036.vdocuments.us/reader036/viewer/2022062509/6105b13577e450315632ffad/html5/thumbnails/22.jpg)
Pathoanatomy
Begins w/ disc degeneration
Disc space collapse
OA of facet joints from abnormal loading
Osteophytes @ facets and bodies
Disc collapse, bulging ligamentum, and
new bone shorten canal and decrease
overall volume
Scoliosis/spondy/ instab worsen stenosis
![Page 23: Common Spine Disorders Diagnosis and Treatment...MRI-HNP Treat patient not x-ray ! 67Asymptomatic volunteers: – MRI + Herniated disc • 60 yo = 36% • >80](https://reader036.vdocuments.us/reader036/viewer/2022062509/6105b13577e450315632ffad/html5/thumbnails/23.jpg)
Inferior articular process
-Located posterior and
medially
-Forms lateral wall of
spinal canal
-Osteophytes cause
central canal
narrowing
![Page 24: Common Spine Disorders Diagnosis and Treatment...MRI-HNP Treat patient not x-ray ! 67Asymptomatic volunteers: – MRI + Herniated disc • 60 yo = 36% • >80](https://reader036.vdocuments.us/reader036/viewer/2022062509/6105b13577e450315632ffad/html5/thumbnails/24.jpg)
Superior articular process
-Located laterally and
anteriorly
-Osteophytes cause
narrowing of :
-lateral recess
-neural foramen

Osteoarthritis
Spondyloarthropathy
– Ankylosing spondylitis

Non-Surgical Treatment
(80-90% of patient) Bed rest (1-2 days)
Traction(at least 25% of body weight)
Acupuncture/trigger point injection
TENS
Corset/Braces
Manipulation
Medication
– NSAID
– Muscle relaxant

Physical Therapy
Aerobic (LA firefighter-higher fitness, lower risk of
subsequent back pain)
Stretching (YMCA-80% improvement/6wks)
Williams isometric flexion program(stenosis, arthritis)
McKenzie extension program (Discogenic)
![Page 30: Common Spine Disorders Diagnosis and Treatment...MRI-HNP Treat patient not x-ray ! 67Asymptomatic volunteers: – MRI + Herniated disc • 60 yo = 36% • >80](https://reader036.vdocuments.us/reader036/viewer/2022062509/6105b13577e450315632ffad/html5/thumbnails/30.jpg)
Epidural Steroid Injections
(ESI)May be helpful in acute flare-ups with
significant radicular complaints and/or
mild/moderate stenosis
Useful in older pt population with many co
morbidities (poor surgical candidates) after
failing medical Rx and PT
Complications - meningitis, nerve injury,
epidural hematoma, arachnoiditis
![Page 31: Common Spine Disorders Diagnosis and Treatment...MRI-HNP Treat patient not x-ray ! 67Asymptomatic volunteers: – MRI + Herniated disc • 60 yo = 36% • >80](https://reader036.vdocuments.us/reader036/viewer/2022062509/6105b13577e450315632ffad/html5/thumbnails/31.jpg)
Epidural Steroid Injections
(ESI)Prospective, randomized, double-blind
study in pts with radicular Sx (~ 50% had
Dx of lumbar stenosis)
No significant difference in symptomatic
improvement between steroid and placebo
injections at 24-hr and 1-year f/u

Surgical Treatment
Is a Quality of Life Issue!
A. Decompression
B. Stabilization

For Stenosis
Decompressive Laminectomy
![Page 34: Common Spine Disorders Diagnosis and Treatment...MRI-HNP Treat patient not x-ray ! 67Asymptomatic volunteers: – MRI + Herniated disc • 60 yo = 36% • >80](https://reader036.vdocuments.us/reader036/viewer/2022062509/6105b13577e450315632ffad/html5/thumbnails/34.jpg)
Surgical Decompression
Open technique
Unilateral/bilateral
laminotomy with
foraminotomy – Focal
lateral stenosis
Up to 50% of facet
joint usually may be
removed w/ low risk
of post-op instability
