What is a Slip Disc?
A slipped disc — medically known as a herniated disc or Prolapsed Intervertebral Disc (PIVD) — occurs when the soft inner core of a spinal disc (nucleus pulposus) pushes through a crack in the tough outer cartilage (annulus fibrosus) and presses on nearby nerves. This is one of the most common causes of severe back and leg pain.
Slip disc most commonly occurs in the lumbar spine (L4-L5 and L5-S1 levels) causing lower back pain and sciatica. It can also occur in the cervical spine (neck) causing arm pain and weakness.
Important: A "slipped" disc doesn't literally slip out of place — it bulges or herniates. The severity ranges from a small bulge (contained herniation) to a large extrusion compressing the spinal cord or nerve roots.
Symptoms
Sharp lower back pain, often sudden onset
Shooting pain down one or both legs (sciatica)
Numbness or tingling in the leg, foot, or toes
Muscle weakness in the leg — difficulty walking on toes/heel
Pain worse with sitting, coughing, or sneezing
Difficulty bending forward or standing straight
Causes & Risk Factors
- Age-related disc degeneration and drying out of disc fluid
- Sudden heavy lifting or twisting movement
- Repetitive strain from occupational activities
- Obesity — increased pressure on lumbar discs
- Sedentary lifestyle and weak core muscles
- Smoking — reduces disc nutrition and accelerates degeneration
Diagnosis
Dr. Chugh evaluates slip disc through clinical examination plus:
- MRI scan — definitive diagnosis of disc herniation and nerve compression
- Neurological examination — checking reflexes, sensation, and muscle strength
- Straight leg raise test — assesses nerve root irritation
- CT myelogram if MRI is contraindicated
Treatment Options
Conservative Care (First Line)
90% of slip disc patients improve with physiotherapy, NSAIDs, nerve pain medications, hot/cold therapy, and activity modification over 6–8 weeks.
Epidural Steroid Injection
Targeted injection of corticosteroid and local anaesthetic around the affected nerve provides significant pain relief and enables physiotherapy.
Endoscopic Discectomy
Keyhole surgery through a 7mm incision to remove the herniated disc fragment. Day care procedure — walk the same day, home next morning.
Microdiscectomy
Microsurgical removal of the herniated disc under microscope. Highly effective with 95%+ success rate for relief of leg pain.
Recovery After Slip Disc Surgery
Day 1–2
Walking & Discharge
Most patients walk within hours of surgery and are discharged home the next day.
Week 1–2
Light Activity
Light walking recommended. Return to desk work possible for many patients.
Week 3–6
Physiotherapy
Core strengthening exercises begin. Most physical activities can be resumed.
Month 3
Full Recovery
Return to normal activities including sports. Pain resolved in 90%+ of patients.
Frequently Asked Questions
Can a slip disc heal without surgery?
Yes. In approximately 90% of cases, slip disc heals naturally over 6–12 weeks with conservative treatment including physiotherapy, pain medications, and lifestyle modification. The herniated disc material is gradually reabsorbed by the body. Surgery is needed only when neurological symptoms are progressive or when conservative treatment fails.
Is endoscopic discectomy better than microdiscectomy?
Both procedures have excellent outcomes with 90–95% success rates. Endoscopic discectomy uses a 7mm incision (vs 3–4cm for microdiscectomy), local anaesthesia, and allows same-day recovery. It is particularly suitable for patients who prefer a faster return to activity and is Dr. Chugh's preferred approach for appropriate candidates.
