Lumbar Disc Herniation — বাংলা Clinical Note
1) Definition / সংজ্ঞা
Lumbar disc herniation হলো কোমরের intervertebral disc-এর nucleus pulposus annulus fibrosus ছিঁড়ে বা দুর্বল হয়ে বাইরে বেরিয়ে গিয়ে nearby nerve root compress/irritate করা। এতে low back pain, radiculopathy/sciatica, sensory–motor deficit, এমনকি bladder/bowel dysfunction হতে পারে।
সাধারণত বেশি হয়:
L4–L5 এবং L5–S1 level-এ।
2) Causes / Etiology — কারণসমূহ
A. Degenerative cause — সবচেয়ে common
- বয়স বাড়ার সাথে disc-এর water content কমে যায়।
- disc শুকিয়ে যায়, elasticity কমে।
- annulus fibrosus দুর্বল হয়ে tear হয়।
- nucleus pulposus posterior/posterolateral দিকে বেরিয়ে nerve root চাপ দেয়।
- intervertebral degeneration lumbar disc herniation-এর common underlying cause।
B. Mechanical stress
- ভারী জিনিস তোলা।
- সামনে ঝুঁকে twisting movement করা।
- হঠাৎ jerk বা lifting injury।
- repeated bending, prolonged sitting, driving vibration।
C. Lifestyle risk factor
- Obesity / overweight।
- Poor posture।
- Core muscle weakness।
- Sedentary lifestyle।
- Smoking — disc nutrition কমিয়ে degeneration বাড়ায়।
D. Occupational factor
- Construction worker, driver, manual laborer।
- দীর্ঘসময় বসে কাজ।
- repeated lifting/twisting job।
E. Trauma
- Fall, accident, direct injury।
- sudden axial loading।
F. Genetic predisposition
- family history থাকলে disc degeneration/herniation risk বাড়তে পারে।
3) Symptoms / Clinical Features — লক্ষণসমূহ
A. Low back pain
- কোমরে ব্যথা।
- sitting, bending, lifting করলে বাড়ে।
- lying down/rest করলে কমতে পারে।
B. Sciatica / Radicular pain
- কোমর থেকে buttock হয়ে পায়ের দিকে ব্যথা যায়।
- pain সাধারণত sharp, shooting, electric shock-like হয়।
- cough/sneeze/straining করলে pain বাড়তে পারে।
C. Numbness / Tingling
- পায়ে ঝিনঝিনি।
- burning sensation।
- dermatomal sensory loss।
D. Muscle weakness
- পায়ের শক্তি কমে যেতে পারে।
- হাঁটতে সমস্যা।
- toe walking বা heel walking দুর্বল হতে পারে।
- L5 involvement হলে foot drop হতে পারে।
E. Reflex changes
- L4 root: knee jerk কমতে পারে।
- S1 root: ankle jerk কমতে পারে।
F. Root-wise clinical pattern
| Nerve root | Pain/Sensory area | Motor weakness | Reflex |
| L4 | anterior thigh, medial leg | knee extension weakness | knee jerk ↓ |
| L5 | lateral leg, dorsum foot, great toe | great toe extension/ankle dorsiflexion weakness | usually normal |
| S1 | posterior calf, lateral foot/sole | plantar flexion weakness | ankle jerk ↓ |
G. Red flag symptoms — emergency
- Urinary retention/incontinence।
- Bowel incontinence।
- Saddle anesthesia।
- Bilateral sciatica।
- Progressive motor weakness।
- Fever, weight loss, cancer history।
- Severe night pain।
- Recent trauma।
NICE guideline বলেছে new/changed low back pain with or without sciatica হলে cancer, infection, trauma, inflammatory disease-এর মতো alternative diagnosis/red flags exclude করতে হবে।
4) Clinical Diagnosis — কিভাবে clinically diagnosis করবেন
A. History
- Pain onset: sudden/gradual।
- Pain radiation: back থেকে leg-এ যায় কিনা।
- Dermatomal pattern আছে কিনা।
- cough/sneeze/strain-এ pain বাড়ে কিনা।
- numbness, weakness, bladder/bowel symptoms।
- trauma, fever, weight loss, malignancy history।
- previous episode, occupational risk।
B. Physical examination
1. Inspection
- posture।
- antalgic gait।
- scoliosis/listing।
- muscle spasm।
2. Range of motion
- lumbar flexion painful/restricted।
- extension painful কিনা।
3. Neurological examination
- Power: hip flexion, knee extension, ankle dorsiflexion, great toe extension, plantar flexion।
- Sensory: L4, L5, S1 dermatome।
- Reflex: knee jerk, ankle jerk।
- Gait: heel walking, toe walking।
4. Special tests
- Straight Leg Raise Test / SLR: 30–70°-এ radicular leg pain হলে positive।
- Crossed SLR: opposite leg raise করলে affected leg pain—more specific for disc herniation।
- Femoral nerve stretch test: upper lumbar root L2–L4 suspicion হলে।
SLR lumbar disc herniation/radiculopathy screening-এ commonly used; sensitivity বেশি হলেও specificity variable, তাই history + neuro exam + imaging correlation জরুরি।
5) Investigations — নির্দিষ্টভাবে কী কী করবেন
A. MRI lumbosacral spine — investigation of choice
Indication:
- severe radicular pain।
- progressive neurological deficit।
- foot drop।
- cauda equina symptoms।
- 4–6 সপ্তাহ conservative treatmentেও improvement না হলে।
- epidural injection/surgery plan করলে।
- red flag থাকলে immediate।
NICE বলেছে non-specialist setting-এ routine imaging করবেন না; specialist setting-এ imaging তখনই করবেন, যখন result management change করবে।
B. X-ray lumbosacral spine
Disc herniation diagnose করার জন্য ভালো test নয়।
Useful when:
- trauma।
- fracture suspicion।
- spondylolisthesis।
- deformity।
- malignancy suspicion।
C. CT scan lumbar spine
Use when:
- MRI contraindicated।
- pacemaker/metallic implant।
- bony canal stenosis better evaluate করতে।
D. CT myelogram
- MRI contraindicated এবং surgical planning দরকার হলে।
- uncommon but useful in selected cases।
E. EMG/NCS
Use when:
- radiculopathy বনাম peripheral neuropathy unclear।
- symptoms chronic।
- clinical–MRI mismatch।
- diabetic neuropathy/peroneal neuropathy differential।
F. Blood tests — routine নয়, red flag থাকলে
- CBC।
- ESR/CRP।
- Blood glucose/HbA1c।
- Renal function: NSAID দেওয়ার আগে।
- LFT: muscle relaxant/other drug consideration।
- Calcium/Vitamin D if osteoporotic fracture suspicion।
6) Differential Diagnosis
- Lumbar spinal stenosis।
- Spondylolisthesis।
- Mechanical low back pain।
- Sacroiliitis।
- Piriformis syndrome।
- Hip osteoarthritis।
- Peripheral neuropathy।
- Peroneal nerve palsy।
- Vertebral fracture।
- Spinal infection।
- Spinal malignancy।
- Cauda equina syndrome।
7) Complications — রোগের জটিলতা
A. Chronic sciatica
দীর্ঘদিন nerve irritation থাকলে persistent leg pain হতে পারে।
B. Motor weakness
Nerve compression দীর্ঘস্থায়ী হলে muscle weakness permanent হতে পারে।
C. Foot drop
বিশেষ করে L5 nerve root compression হলে পায়ের dorsiflexion দুর্বল হয়ে foot drop হতে পারে।
D. Sensory loss
পায়ে numbness বা sensation loss দীর্ঘস্থায়ী হতে পারে।
E. Cauda equina syndrome
এটি emergency।
লক্ষণ:
- urinary retention।
- bowel dysfunction।
- saddle anesthesia।
- bilateral leg weakness/sciatica।
F. Chronic disability
দীর্ঘদিন pain থাকলে কাজের ক্ষমতা কমে, sleep disturbance, anxiety/depression হতে পারে।
G. Recurrence
Conservative বা surgery—দুই ক্ষেত্রেই recurrence হতে পারে, especially posture/lifting habit ঠিক না করলে।
8) Treatment / Management — Guideline-based
A. General principle
- Most patients conservative management-এ improve করে।
- bed rest দীর্ঘদিন নয়।
- activity maintain করতে হবে।
- physiotherapy + education + analgesia।
- red flag থাকলে urgent referral।
NICE self-management ও normal activity continue করার advice দিতে বলেছে।
B. Non-pharmacological treatment
1. Patient education
- রোগীকে বুঝাতে হবে disc herniation মানেই surgery নয়।
- অধিকাংশ acute case 6–12 সপ্তাহে improve করে।
2. Activity modification
- heavy lifting বন্ধ।
- repeated bending/twisting avoid।
- prolonged sitting avoid।
- complete bed rest avoid।
3. Physiotherapy
- McKenzie extension exercise।
- core strengthening।
- hamstring stretching।
- neural mobilization।
- posture correction।
- graded walking program।
NICE low back pain/sciatica-তে exercise program consider করতে বলেছে।
4. Manual therapy
Manual therapy only as part of treatment package with exercise; standalone routine নয়।

11) Prevention — কীভাবে প্রতিরোধ করবেন
A. Posture correction
- prolonged sitting avoid।
- lumbar support ব্যবহার।
- প্রতি ৩০–৪৫ মিনিটে দাঁড়ানো/হাঁটা।
B. Proper lifting technique
- কোমর বাঁকিয়ে নয়, knee bend করে lift।
- weight body-এর কাছে রাখতে হবে।
- twisting while lifting avoid।
C. Core strengthening
- plank।
- pelvic tilt।
- bridge exercise।
- McKenzie extension if tolerated।
- supervised physiotherapy better।
D. Weight control
- BMI normal রাখা।
- abdominal obesity কমানো।
E. Smoking cessation
- smoking disc degeneration বাড়ায়।
F. Regular activity
- walking।
- swimming।
- low-impact aerobic exercise।
G. Workplace ergonomics
- chair height ঠিক রাখা।
- monitor eye level।
- long driving হলে break নেওয়া।
Overview / Summary
Lumbar disc herniation হলো lumbar disc-এর nucleus pulposus বেরিয়ে nerve root compress/irritate করা, যার ফলে low back pain, sciatica, numbness, weakness হতে পারে। Diagnosis মূলত history + neurological examination + SLR/crossed SLR দিয়ে clinically suspected হয়; MRI প্রয়োজন red flag, progressive neuro deficit, persistent symptoms বা intervention planning-এ। Treatment প্রথমে conservative: education, activity, physiotherapy, short-course analgesic/NSAID ± PPI ± muscle relaxant। Severe refractory sciatica হলে epidural steroid injection, আর cauda equina/progressive weakness/persistent disabling MRI-correlated radiculopathy হলে surgery consideration।
Actionable Plan / Steps
- Red flag check করুন: urinary retention, saddle anesthesia, bilateral sciatica, progressive weakness থাকলে urgent MRI/referral।
