Lumbar Disc Prolapse / Lumbar Disc Herniation — বাংলায় ক্লিনিক্যাল নোট
নোট: নিচের ডোজগুলো adult patient-এর জন্য clinical reference; renal disease, liver disease, peptic ulcer, anticoagulant use, pregnancy, elderly, uncontrolled HTN/IHD/CKD থাকলে ডোজ/ড্রাগ বদলাতে হবে। Lumbar disc prolapse-এ guideline অনুযায়ী NSAID lowest effective dose, shortest duration; routine gabapentinoid/oral steroid/opioid ব্যবহার evidence-based নয়—তবে বাংলাদেশে অনেক clinician selected case-এ symptomatic trial দেন। NICE sciatica guideline gabapentinoids, oral corticosteroids, benzodiazepines এবং chronic sciatica-তে opioids avoid করতে বলেছে; NSAID দিলে GI/liver/cardio-renal risk assess করে gastroprotection বিবেচনা করতে বলেছে।
1. Definition / সংজ্ঞা
Lumbar disc prolapse হলো lumbar intervertebral disc-এর nucleus pulposus বা disc material annulus fibrosus-এর দুর্বল/ফাটা অংশ দিয়ে posterior বা posterolateral দিকে বের হয়ে nerve root compression / chemical inflammation তৈরি করা। এর ফলে low back pain, sciatica/radicular leg pain, numbness, weakness হতে পারে। NASS lumbar disc herniation with radiculopathy guideline-এর উদ্দেশ্যই symptomatic lumbar disc herniation with radiculopathy-এর diagnosis ও treatment নিয়ে evidence-based recommendation দেওয়া।
Common level: L4–L5 ও L5–S1 বেশি।
Most common direction: posterolateral, কারণ posterior longitudinal ligament মাঝখানে শক্তিশালী।
2. Cause / Etiology — কারণগুলো
A. Mechanical / Degenerative cause
- Disc degeneration: বয়সের সাথে disc dehydration, proteoglycan কমে যাওয়া, annulus fibrosus fissure।
- Repeated flexion + rotation injury: সামনের দিকে ঝুঁকে ভারী জিনিস তোলা, twisting movement।
- Heavy lifting / manual work: sudden raised intradiscal pressure।
- Prolonged sitting: especially flexed posture, driving, desk work।
- Poor core muscle strength: abdominal–paraspinal support কমে যায়।
- Obesity: lumbar spine-এর axial load বাড়ায়।
- Smoking: disc nutrition ও healing capacity কমাতে পারে।
- Trauma: fall, road traffic accident, sudden jerk।
- Genetic predisposition: family history থাকলে early degeneration হতে পারে।
B. Pathophysiology — সহজভাবে
- Disc-এর outer ring = annulus fibrosus দুর্বল/ফেটে যায়।
- Inner gelatinous material nucleus pulposus বের হয়।
- বের হওয়া disc nearby nerve root চাপ দেয়।
- শুধু compression নয়—disc material inflammatory mediators ছাড়ে, তাই chemical radiculitis হয়।
- ফলে nerve root pain pathway activate হয়ে buttock → thigh → leg → foot পর্যন্ত radiating pain হয়।
3. Symptoms — লক্ষণগুলো
A. Pain pattern
- Low back pain: কোমরের নিচে ব্যথা; bending, sitting, coughing/sneezing-এ বাড়তে পারে।
- Sciatica / radicular pain: কোমর থেকে নিতম্ব হয়ে পায়ের দিকে নামা sharp, burning, electric shock-like pain।
- Dermatomal pain distribution:
- L4 root: anterior thigh/medial leg, knee reflex কমতে পারে।
- L5 root: lateral leg, dorsum of foot, great toe extension weakness।
- S1 root: posterior thigh/calf, lateral foot, ankle reflex কমতে পারে।
B. Sensory symptoms
- পায়ে ঝিনঝিন/পিন-নিডল sensation।
- নির্দিষ্ট dermatome-এ numbness।
- পায়ের পাতায় burning sensation।
C. Motor symptoms
- পা দুর্বল লাগা।
- Foot drop: L5 involvement হলে ankle dorsiflexion / great toe extension weak।
- Toe walking difficulty: S1 weakness।
- Heel walking difficulty: L4/L5 weakness।
D. Red flag symptoms — emergency
- Urinary retention/incontinence
- Fecal incontinence
- Saddle anaesthesia
- Bilateral sciatica with neurological deficit
- Progressive motor weakness / foot drop
- Fever, weight loss, history of cancer, IV drug use, TB risk
- Major trauma বা osteoporosis patient-এ sudden severe back pain
এগুলো থাকলে urgent MRI + neurosurgery/orthospine referral।
4. Clinical Diagnosis — clinically কীভাবে ধরবেন
A. History
- Pain onset: sudden lifting/twisting after?
- Back pain vs leg pain dominance: disc prolapse-এ leg pain often more prominent।
- Pain below knee গেলে radiculopathy বেশি suggestive।
- Cough/sneeze/strain-এ pain বাড়ে কি না।
- Weakness, numbness, bladder/bowel symptom।
- Previous episodes, occupation, smoking, trauma।
- Red flags: cancer, fever, TB, immunosuppression, steroid use।
B. Physical examination
1. Inspection
- Antalgic posture
- Lumbar lordosis loss
- Sciatic scoliosis
- Gait abnormality
2. Range of motion
- Forward flexion painful/restricted
- Extension may aggravate foraminal narrowing
3. Neurological exam — must do
| Root | Motor test | Sensory area | Reflex |
| L4 | Knee extension, ankle dorsiflexion partly | medial leg | patellar reflex |
| L5 | Great toe extension, ankle dorsiflexion | dorsum foot, great toe | no reliable deep tendon reflex |
| S1 | Plantar flexion, toe walking | lateral foot/sole | Achilles reflex |
4. Special tests
- Straight Leg Raise / SLR / Lasègue test: supine অবস্থায় leg raise করলে 30–70°-এ radicular pain হলে positive। এটি lumbosacral nerve root irritation suggest করে।
- Crossed SLR: asymptomatic leg raise করলে affected leg pain—less sensitive but more specific for disc herniation।
- Slump test: seated neural tension test; subtle radiculopathy ধরতে helpful।
- Femoral nerve stretch test: L2–L4 upper lumbar radiculopathy suspicion হলে।
5. Investigations — specificভাবে
NICE guideline অনুযায়ী non-specialist setting-এ low back pain/sciatica হলে routine imaging করা উচিত নয়; specialist setting-এ imaging করবেন যদি result management change করে।
A. MRI lumbosacral spine — investigation of choice
Indication:
- Severe/progressive neurological deficit
- Cauda equina suspicion
- Persistent radicular pain > 6 weeks despite conservative therapy
- Surgery/epidural injection planning
- Diagnostic uncertainty
MRI report-এ দেখতে হবে:
- Disc level: L3–L4, L4–L5, L5–S1
- Type: bulge, protrusion, extrusion, sequestration
- Direction: central, paracentral, foraminal, extraforaminal
- Nerve root compression
- Canal stenosis / foraminal stenosis
B. X-ray lumbosacral spine
Disc prolapse diagnose করার test নয়। তবে trauma, deformity, spondylolisthesis, infection/malignancy suspicion, instability evaluation-এ helpful।
C. CT scan / CT myelogram
MRI contraindicated হলে—pacemaker/metal implant/claustrophobia—CT বা CT myelogram consider।
D. EMG/NCS
- Diagnosis unclear হলে
- Radiculopathy vs peripheral neuropathy differentiate করতে
- Chronicity/denervation assess করতে
NASS guideline summary অনুযায়ী EMG/NCS/F-wave limited diagnostic utility; H-reflex S1 radiculopathy-তে helpful হতে পারে, কিন্তু disc herniation-specific নয়।
E. Lab tests — only if red flag
- CBC, ESR, CRP: infection, TB, malignancy suspicion
- Calcium/ALP: malignancy/metabolic bone disease suspicion
- Urine R/M/E: renal/urinary differential
- HLA-B27, inflammatory markers: inflammatory back pain suspicion
6. Differential Diagnosis
- Lumbar spinal stenosis
- Spondylolisthesis
- Facet joint arthropathy
- Sacroiliitis / ankylosing spondylitis
- Piriformis syndrome
- Hip osteoarthritis
- Peripheral neuropathy / diabetic neuropathy
- Peroneal neuropathy
- Vertebral fracture
- Spinal infection / TB spine
- Metastatic spinal disease
- Renal colic / pelvic pathology
7. Complications — রোগের জটিলতা
- Chronic sciatica: nerve irritation দীর্ঘস্থায়ী হলে pain sensitization হয়।
- Persistent numbness: nerve compression দীর্ঘদিন থাকলে sensory recovery incomplete হতে পারে।
- Motor weakness / foot drop: L5 root severely compressed হলে হাঁটতে সমস্যা।
- Cauda equina syndrome: central large disc bladder/bowel ও saddle area nerve compress করে—এটি surgical emergency।
- Chronic low back pain: pain avoidance → muscle deconditioning → recurrent pain cycle।
- Depression/anxiety/sleep disturbance: chronic pain functional life নষ্ট করে।
- Work disability: দীর্ঘদিন বসা/ভারী কাজ করা কঠিন।
- Recurrent disc herniation: surgery বা conservative treatment—দুই অবস্থাতেই recurrence হতে পারে।
8. Treatment / Management
A. Emergency management
নিচের যেকোনোটি থাকলে urgent MRI + emergency spine referral:
- Cauda equina symptoms
- Progressive motor deficit
- Acute foot drop
- Severe bilateral sciatica
- Infection/malignancy suspicion
- Major trauma
B. Conservative non-pharmacological management
NICE self-management, normal activity চালিয়ে যাওয়া, exercise programme, manual therapy only with exercise package, return-to-work facilitation recommend করে; traction/TENS/ultrasound routine recommend করে না। ACP guideline acute/subacute low back pain-এ non-drug options আগে বিবেচনা করতে বলে; drug needed হলে NSAID বা skeletal muscle relaxant ব্যবহার করা যায়।
করণীয়
- Relative rest 24–48 hours: absolute bed rest avoid।
- Activity as tolerated: pain limit অনুযায়ী হাঁটা, normal activity।
- Physiotherapy: McKenzie extension exercise, core strengthening, hamstring stretch, neural mobilization।
- Heat therapy: muscle spasm থাকলে।
- Posture correction: sitting ergonomics, lumbar support।
- Weight reduction if overweight।
- Smoking cessation।
- Work modification: heavy lifting, forward flexion, twisting avoid।
9. Pharmacological Management — Bangladesh prescription-style drug list

10. Bangladesh doctors’ common prescription drug groups — কেন দেন?
- NSAID: Naproxen / Aceclofenac / Diclofenac / Etoricoxib — pain + inflammation কমাতে।
- PPI: Esomeprazole — NSAID-induced gastritis/ulcer prevention।
- Muscle relaxant: Tizanidine / Tolperisone — paraspinal spasm কমাতে।
- Adjunct analgesic: Paracetamol — mild pain বা NSAID contraindication adjunct।
- Neuropathic pain agent: Pregabalin / Gabapentin — burning radicular pain-এর trial; guideline caution।
- Short-course opioid: Tramadol — severe acute pain only; chronic use avoid।
- Steroid: Methylprednisolone — some local practice, but routine guideline-supported নয়; acute severe sciatica হলে epidural steroid specialist procedure হিসেবে consider।
11. Interventional / Surgical treatment
A. Epidural steroid injection
- Acute severe sciatica, severe radicular pain, conservative treatmentে inadequate response হলে specialist setting-এ consider।
- NICE acute severe sciatica-তে epidural local anaesthetic + steroid consider করতে বলেছে।
B. Surgery — microdiscectomy / endoscopic discectomy
Indication:
- Cauda equina syndrome — emergency
- Progressive motor deficit / foot drop
- Persistent disabling sciatica > 6–12 weeks despite conservative treatment
- MRI finding matches clinical level
- Recurrent severe radicular pain with neurological deficit
NICE sciatica-তে non-surgical treatmentে pain/function improve না হলে এবং radiology symptom-এর সাথে consistent হলে spinal decompression consider করতে বলেছে। Early surgery faster sciatica relief দিতে পারে, তবে অনেক trial-এ 1-year outcome conservative care-এর সাথে কাছাকাছি।
12. Prevention — কীভাবে প্রতিরোধ করবেন
- Proper lifting technique: কোমর না ভেঙে knee bend করে weight body-এর কাছে রাখুন।
- Avoid flexion + twisting: বিশেষ করে ভারী জিনিস তোলার সময়।
- Core strengthening: abdominal, multifidus, gluteal strengthening।
- Regular walking/swimming: low-impact aerobic exercise।
- Weight control: BMI high হলে lumbar load কমাতে weight reduction।
- Stop smoking: disc nutrition ও healing-এর জন্য।
- Ergonomic sitting: chair lumbar support, screen eye level, 30–45 min পরপর standing break।
- Driving: long drive-এ lumbar roll, interval break।
- Sleep posture: side lying with pillow between knees বা supine with pillow under knees।
- Exercise + education: systematic review অনুযায়ী exercise alone বা educationসহ exercise low back pain prevention-এ effective হতে পারে।

Lumbar disc prolapse হলো lumbar disc material বের হয়ে nerve root compress/inflame করা। প্রধান লক্ষণ হলো low back pain + sciatica, dermatomal numbness, reflex change, weakness। Diagnosis primarily clinical, MRI দরকার হয় red flag, neurological deficit, persistent radicular pain বা intervention planning-এ। অধিকাংশ রোগী conservative treatment—activity, physiotherapy, NSAID-based pain control, education—দিয়ে ভালো হয়। Emergency signs: bladder/bowel dysfunction, saddle anaesthesia, progressive weakness/foot drop।
Actionable Plan / Steps
- Red flag screen করুন: bladder/bowel, saddle anaesthesia, progressive weakness, fever/cancer/trauma।
- Neurological chart করুন: L4/L5/S1 motor, sensory, reflex, SLR/crossed SLR।
- No red flag হলে: 2–6 সপ্তাহ conservative management—activity, physio, NSAID ± PPI, short muscle relaxant।
- Persistent radicular pain >6 weeks বা deficit থাকলে: MRI lumbosacral spine।
- Severe acute sciatica: specialist referral for epidural steroid consideration।
- Cauda equina/foot drop/progressive deficit: urgent MRI + emergency spine surgery referral।
- Prevention: core exercise, weight control, ergonomic correction, lifting technique, smoking cessation।
