Prolapse Intervertebral Disk
PID
• Lumber back ache is
most common cause of
chronic disability.
• Majority of case are
associated with Inter
vertebral disk at L5 /
S1.
Pathology
• With ageing disk dries out the
nucleus pulposes turgid and
gelatinous bulb to desiccated
structure annulus fibrosis develop
fissure .
• Small herniation of nucleus
material squeeze through the
annulus.
• They penetrate the vertebral end
plate to produce SCHMORLS nodes
in 75 % of pt
• Displacement of facet joint is
inevitable due to disk space
collapse leading to OA.
Acute disk herniation or prolapse
• Less common but more dramatic.
• Physical stress is the causative factor.
• The dick will not rupture unless there is disturbance in hydrophilic property
of nucleus.
• When it rupture fibro cartilaginous material extrude posteriorly.
• With complete rupture nucleus may sequestrate and lie free spinal cord.
• Pain in PID is due to disruption of annulus fibrosis and tearing of post
longitudinal ligament and dura.
Stage
Clinical Features
• There is
–Sciatic radiation
–Parenthesis
–Numbness
–Weakness
–Depress reflex may be present
Clinical Feature
• Acute PID is uncommon in very young and very old.
• It occur in fit adult of 20 to 45 years.
• There is H/O lifting and stooping.
• Pain will be more on coughing and straining.
• Cauda equana is affected to cause urinary retention.
• There is sciatic sclerosis.
• Range of motion diminished.
• Para vertebral muscles spasm.
• SLR positive.
• Cross sciatic test may be positive.
Imaging
• X-ray
• Myelography( for rediculopathy)
• CT and MRI
Differential Diagnosis
• Inflammatory diseases
• Vertebral tumor
• Nerve tumor
Treatment
• 4R’s
–Rest
–Reduction
–Removal
–Rehabilitation
