Slipped Disc Surgery in Delhi

A slipped disc occurs when the soft, jelly-like centre of a spinal disc pushes through a tear in its outer wall and presses on nearby spinal nerves, often causing sharp or radiating pain, numbness or weakness in the back, arm or leg. Most herniated discs settle within four to six weeks with non-surgical care. Where symptoms persist, slipped disc surgery removes the portion of the disc pressing on the nerve.

Several surgical techniques exist to relieve pressure on the spinal cord and nerves. This page compares the main options and explains who may benefit, the risks involved, and what recovery looks like — as general education rather than personal medical advice.

What is slipped disc surgery?

Slipped disc surgery, broadly called a discectomy, removes the damaged part of a herniated disc. By relieving pressure on the nearby spinal nerve, it interrupts the signals causing pain, numbness and weakness. It is most commonly performed for lumbar disc herniation.

Radiating pain — sciatica in the leg, or neck-related arm pain — arises when tissue, bone or disc material presses on a spinal nerve as it leaves the spine, a condition called radiculopathy. Slipped disc surgery mainly targets symptoms caused by that pinched nerve. Where there is progressive weakness in the leg or foot, difficulty lifting the foot (foot drop), or loss of bladder or bowel control, surgery may be considered immediately.

Techniques vary by incision size, the location of the herniation, the degree of tissue disruption and the tools used to visualise the affected nerve and disc:

• Open discectomy — a traditional approach through a larger incision, typically 2 to 3 inches, to access and remove the herniated portion pressing on the nerve.
• Microdiscectomy — minimally invasive surgery through a smaller incision using a microscope. Muscle fibres are gently parted rather than cut, causing less tissue disruption than open surgery.
• Endoscopic discectomy — an advanced approach through a 7–8 mm incision, using a pencil-thin tube with a camera to remove the herniated fragment.

All share the same fundamental goal: relieving pressure on the pinched spinal nerve. Surgery is usually considered only after conservative treatment — anti-inflammatory medication, pain relief, physiotherapy, injections and rest — has been tried.

Who is a candidate? (Indications)

Surgery is generally considered when significant nerve-related symptoms — severe radiating pain, progressive muscle weakness or loss of function — persist despite weeks of appropriate non-surgical care. Common indications and warning signs include:

• Persistent or worsening leg or arm pain from a confirmed herniation that fails to settle after 6–12 weeks of structured non-surgical treatment.
• Symptoms that correspond to the imaging findings on MRI or CT.
• Significant or progressive lower limb weakness.
• Cauda equina syndrome — loss of bladder or bowel control with saddle numbness (loss of sensation around the genital area, so the urge to pass urine or stool is lost). This is an emergency requiring urgent surgery.

Most people with a slipped disc do not require surgery and recover as the body gradually reabsorbs the bulging disc material over weeks or months. The decision is individual.

How the procedure is performed

While details differ across approaches, the general steps are similar:

1. Anaesthesia and positioning. Most procedures are performed under general anaesthesia, so the patient is asleep throughout. Regional anaesthesia is used in some cases. The patient is positioned face down on a specialised surgical table.
2. Access. A small tube and high-powered microscope are used to reach the disc. Depending on the diagnosis, an endoscopic portal technique may be used instead.
3. Exposure of the nerve. The surgeon gently moves the affected nerve root aside and protects it.
4. Removal of the herniation. The protruding fragment pressing on the nerve is removed or trimmed.
5. Checking decompression. The surgeon confirms the nerve root is free of pressure.
6. Closure. The incision is closed with stitches, staples or surgical glue and covered with a sterile dressing. In minimally invasive approaches the incision is small and needs minimal stitching.

Benefits and risks

Fear of surgery keeps some people from seeking relief, but techniques have evolved considerably. Minimally invasive procedures involve smaller incisions and less disruption to surrounding tissue, and many patients begin light activity such as walking the same day, with discharge often within 24–48 hours.

Discectomy removes the fragment compressing the spinal nerve and can relieve nerve-related leg or arm pain quickly. Smaller incisions may reduce tissue disruption and support faster recovery compared with more extensive open procedures.

Risks and limitations. As with any spinal surgery, there are real risks, including:

• Infection or wound problems — uncommon, reported in a small percentage of procedures.
• Bleeding.
• Dural tear with cerebrospinal fluid leak.
• Post-operative pain.
• Nerve root injury.
• Incomplete relief of symptoms.
• Recurrent herniation at the same level, when remaining disc material displaces again. Reported rates vary between published series and between individuals.

Back pain improves less reliably than leg or arm pain, because back pain often stems from general wear and tear rather than direct nerve compression. No procedure, surgical or non-surgical, can guarantee complete or permanent relief.

Alternatives

For most slipped discs, non-surgical treatment is the recommended first approach — most patients improve naturally within four to six weeks through physiotherapy, activity modification, pain-relieving medication and, in some cases, spinal injections.

Many people recover without surgery within six weeks to three months. Where surgery is appropriate and conservative treatment has failed, the choice between open, microscopic and endoscopic techniques depends on the location of the herniation (neck, mid-back or lower back), the severity of symptoms, and whether there are warning signs such as progressive weakness or loss of bladder or bowel control.

Recovery and outlook

Recovery typically takes about four to six weeks, though the timeline varies with the approach and the individual, and full healing may take three to four months. Much depends on whether the procedure was a minimally invasive microdiscectomy or a more extensive open operation.

• Early days: Many patients go home the same day or after a short stay, depending on the complexity of surgery and overall health, and are encouraged to begin gentle walking to promote circulation and healing.
• First weeks: Through the second to fourth week, patients gradually return to light activity, with restrictions on heavy lifting, bending and twisting.
• Following weeks: Activity is increased steadily over several weeks, often under the guidance of a physiotherapist.

Leg or arm pain often improves quickly, but full healing takes weeks to months, and residual symptoms or a degree of recurrence remain possible. Outcome depends on age, overall health, pre-existing fitness, the type of surgery performed, and adherence to the pain-management and physiotherapy plan.

When to seek a specialist opinion

A slipped disc can cause debilitating back, neck, leg or arm pain, with tingling, numbness and weakness that makes everyday movement difficult. For some, symptoms stay mild and improve with rest, anti-inflammatory medication and physiotherapy. For others, pressure on the nerve becomes severe and intolerable.

Consider a specialist assessment if you have persistent leg or arm pain, numbness or weakness that limits bending, twisting or lifting despite appropriate non-surgical treatment. Seek urgent medical attention for rapidly worsening muscle weakness, numbness around the groin or buttocks with loss of bladder or bowel control, or severe pain that does not respond to medication. A spine specialist can advise whether surgery is appropriate and which approach suits your situation.
