Lumbar Spine Pathology Flashcards
- Disc Herniation
Protrusion
NP bulges out through the tear to strain, but escape, te outer AF
- Disc bulges against the dura and posterior longitudinal ligament
- Dull, poorly localized low back and sacroiliac pain
- Pain worse in am, with sitting and bending
- Minimal to no leg pain, -SLR
Disc Herniation
Extrusion/Prolapse
-NP material bulges out through the tear to strain, but not escape , the outer AF
-Disc bulges against the dura and posterior longitudinal ligament
-Dull, poorly localized low back and sacroiliac pain
-Pain worse in the am, with sitting and bending
-Minimal to no leg pain, SLR
(happy with Extension to relieve posterior Annulus pain—dull deep not specifically localized pain) WIll be very sore in the morning.
Disc Herniation Sequestration
NP material breaks contact with the disc and becomes fragment in the intervertebral canal
Complete disruption of the annular wall
Fragments can lead to cauda equina syndrome
Strains
• Associated with a history of
trauma
• Caused by excessive muscle activity or muscle guarding
• Common locations
– Erector spinae common tendon just superior and lateral
to the PSIS
– Gluteal attachment on the
sacrum just lateral to the
PSIS
• Treatment: progressive movement and funtional
activities
Piriformis Syndrome
• 15% of the population have anatomic anomaly • Cardinal features – Hx of trauma to the SI or gluteal region – Pain in the region of the SIJ, greater sciatic notch, and piriformis extending down the leg – Symptoms exacerbated by stooping or lifting – Tender, palpable mass over the piriformis – + SLR – Gluteal atrophy • Treatment: stretching and massage
Facet Joint Syndrome
• Pain from the joint and its pain sensitive structures – Meniscoid entrapment, capsular tightness, muscle strain – Can result from hyper-‐or hypomobility – Localized unilat. LBP aggravated with specific movements, may have referred pain, - (‐neurosigns)
Spinal Stenosis
• Causes – Congenital, born with a smaller canal – Acquired, osteophytes from facets, laminae or pedicle • Signs and Symptoms – Back and LE pain or weakness – Multiple level findings are more common – Single level findings more common for HNP
Central Stenosis
– Narrowing of the spinal canal
– Caused by: facet joint arthrosis, bulging of the disc,
thickening of the ligamentum
flavum
Lateral Stenosis
– Spinal nerve compression in
the IVF or lateral recess of the
spinal canal
– Caused by: facet joint hypertrophy, dcreased disc height, bulging disc
Spinal Stenosis
• Elderly population, >50yo • Long history of LBP • Unilateral or bilateral leg pain • Neurogenic claudication pain with walking and standing, • Relief with siting • Decreased lordosis
Disc Disease
• With age the AF weakens and
the NP dehydrates aHer 25 yo.
• Trauma, combined with weakened muscles and stretched ligaments of the spine
– hernia<on can occur
• Risk is different depending on
the health of the person
– Smoking a significant risk factor for disc disease
Amount of Body Weight will be increased with posture changes

Degenerative Disc Disease
Degenerative changes are the body’s attempts at healing as it ages.
Early dysfunction
–disc herniation occurs at theis stage, see splits in the AF
–End plate fractures and Schmorl’s nodes
Degenerative Disc Disease
Immediate instability
–characterized by laxity of the posterior joint capule and posterior AF
–Increased loading results in increased fatigue damage
(episodes of back pain several times a year,,,instability tests poor responses…hyper mobility on central and unilateral PA’s…episodes of pain will get closer together and increase with time)
Degenerative Disc Disease
Final Stabilization
–characterized by al loss of disc material, decreased disc height, redial tears in the AF, osteophyte formation, fibrosis of the facet joints and capsule
-Osteophytes increase load bearing surface, decrease available motion, stiffer segment
—end game of the degenerative cascade is loosing all motion at all and a great amount of stiffness in the effected segments–Stiffness can decrease pain though!
Cause irritability of the surrounding joints trying to overcome for lack of motion
