Objectives
• Define and understand low back pain (LBP).
• Discuss epidemiology and risk factors.
• Review relevant anatomy of the spine.
• Understand causes and clinical features.
• Discuss investigations and management.
• Highlight prevention and key takeaways.
Introduction
• Low back pain is a common musculoskeletal condition.
• Affects up to 80% of adults at some point in life.
• One of the leading causes of disability worldwide.
• Significant socioeconomic and healthcare burden.
Epidemiology
• Lifetime prevalence: 60–80% of population.
• Most common in ages 30–50 years.
• Higher prevalence in sedentary lifestyle populations.
• Accounts for significant work absenteeism.
Relevant Anatomy of the Spine
• Five lumbar vertebrae (L1–L5).
• Intervertebral discs act as shock absorbers.
• Supporting muscles: erector spinae, multifidus.
• Nerve roots and spinal cord involvement important in LBP.
Causes of Low Back Pain
• Mechanical: muscle strain, ligament injury.
• Degenerative: disc herniation, osteoarthritis.
• Traumatic: fractures, spondylolisthesis.
• Inflammatory: ankylosing spondylitis.
• Other: infections, tumors, referred pain.
Risk Factors
• Poor posture and ergonomics.
• Sedentary lifestyle or lack of exercise.
• Occupational heavy lifting or repetitive strain.
• Obesity and poor core muscle strength.
• Smoking and psychosocial factors.
Clinical Features
• Localized or radiating back pain.
• Stiffness and limited range of motion.
• Neurological symptoms: numbness, tingling, weakness.
• Red flag symptoms: fever, weight loss, night pain, bladder/bowel
dysfunction.
Differential Diagnosis
• Herniated disc.
• Spinal stenosis.
• Ankylosing spondylitis.
• Osteoporotic compression fracture.
• Metastatic spinal tumor.
• Pyogenic spondylitis.
Investigations
• X-ray: rule out fractures, degenerative changes.
• MRI: gold standard for soft tissue evaluation.
• CT scan for detailed bony anatomy.
• Blood tests: ESR, CRP for infection/inflammation.
• Electromyography (EMG) for nerve involvement.
Management
• Conservative: rest, posture correction, physical therapy.
• Medical: analgesics (NSAIDs), muscle relaxants.
• Interventional: epidural steroid injections.
• Surgical: discectomy, laminectomy (severe cases).
Prevention
• Maintain healthy body weight.
• Regular exercise to strengthen core muscles.
• Proper lifting techniques.
• Ergonomic workplace setup.
• Avoid prolonged sitting and inactivity.
Complications if Untreated
• Chronic back pain and disability.
• Nerve damage leading to weakness or paralysis.
• Cauda equina syndrome.
• Reduced quality of life and productivity.
Case Example
• A 35-year-old office worker with 3 months of lower back pain.
• Pain worsens after long sitting hours.
• No neurological deficits, no red flag signs.
• Diagnosis: Mechanical low back pain.
• Treatment: Conservative management with exercise and posture
correction.
Summary
• Low back pain is a leading cause of disability.
• Most cases are mechanical and self-limiting.
• Identify red flags to rule out serious pathology.
• Management is stepwise: conservative → medical → surgical.
• Prevention is key to reducing recurrence.
