• Lumbago is acute low backache.
• Sciatica is the neuralgic pain that starts in the back and radiates along the posterior aspect of lower limb to heel.
Causes
• Combination of lumbago with sciatica is invariably due to acute intervertebral disc protrusion in the lumbar region (L3-L4; L4-L5; L5-S l ).
• Other rare causes are the following:
• Metastasis
• Tumours
• Tuberculosis of spine
• Spinal canal stenosis
Clinical Features of lntervertebral Disc Prolapse (IVDP)
Lumbago
• Lumbago is localised low backache in the midline that increases on movements of spine or straining (like coughing, sneezing, etc.). There is associated paraspinal muscular spasm.
• Pain starts acutely, usually while attempting to lift weight in bent posture. Lumbago may or may not be associated with sciatica.
Sciatica
• Also known as lumbar radicular pain.
• Occurs due to irritation of a spinal root compressed by the protruded disc close to the intervertebral foramen.
• Pain is shooting, burning or shock-like in character. It maybe continuous or brought on by spinal movements and straining.
• Patient prefers to lie down on his sides with flexed lower limbs.
• Syndrome of pain may or may not be associated with symptoms of neurological deficit, which depends on the root involved.
• L4 root Weakness of invertors of foot, sensory impairment at L4 dermatome (inner aspect of leg) and depressed knee jerk
• LS root Weakness of extensor hallucis longus with sensory impairment at LS dermatome (outer aspect of leg and dorsum of foot)
• S1 root Weakness of plantar flexors of toes, foot and hamstrings with depressed ankle jerk and sensory impairment at S1 dermatome (outer aspect of foot)
• Positive straight leg raising (SLR) test is present.
• Large disc protrusions may cause bilateral, more extensive neurological deficit (cauda equina syndrome)
Investigations
• Plain radiograph of lumbosacral spine:
• Loss of lumbar lordosis
• Scoliosis
• Reduced intervertebral disc space
• On most occasions, radiograph is normal
• CT scan shows the protruded disc. MRI is more sensitive and specific.
Management
• Bed rest for 1-3 weeks; however, presently early return to daily activities is encouraged.
