Disc Replacement Surgery in Delhi, India

Disc replacement surgery is a procedure where a damaged spinal disc is removed and replaced with an artificial disc, usually made from metal or plastic. The goal is to reduce pain and improve spinal movement, making everyday activities like bending and twisting more comfortable. By replicating the natural function of a healthy disc, this surgery can help maintain spinal flexibility and potentially decrease the risk of future disc degeneration.

Disc replacement surgery may be considered when other treatments do not provide enough relief. It is usually recommended in the following cases:

• Degenerative Disc Disease (DDD): When one or two discs in the lower back wear out, causing constant pain that does not improve with non-surgical treatments.
• Herniated Disc: A bulging disc pressing on nearby nerves can result in pain, numbness, or weakness. If these symptoms persist despite other treatments, surgery might be an option.
• Chronic Disc-Related Back Pain: Long-term back pain from disc wear and tear can make daily activities difficult to manage.
• Cervical Radiculopathy or Myelopathy: A damaged disc in the neck may press on nerves, leading to pain in the arms or difficulties with movement and coordination. In such cases, surgery might be suggested to relieve pressure and support neck movement.

Doctors evaluate spinal health, medical history, and symptoms before deciding if disc replacement surgery is a suitable option.

Disc replacement surgery is a motion-preserving alternative to spinal fusion, designed to relieve pain and restore flexibility by replacing a damaged spinal disc with an artificial implant. Depending on the affected area and the extent of damage, different types of disc replacement procedures may be recommended.

Cervical Disc Replacement (CDR)

Performed in the neck region, cervical disc replacement is commonly advised for patients with cervical disc herniation or degenerative disc disease. By replacing the damaged disc with an artificial one, this procedure helps relieve neck and arm pain while preserving natural neck movement. It also offers a quicker recovery and lowers the risk of future problems in nearby spinal segments, which can occur with spinal fusion.

Lumbar Disc Replacement (LDR)

This surgery targets the lower back and is typically recommended for individuals with chronic back pain due to lumbar disc degeneration. By maintaining flexibility in the lower spine and avoiding the rigidity associated with fusion surgery, lumbar disc replacement helps reduce pain, improve mobility, and support long-term spine health.

Total Disc Replacement (TDR)

Total disc replacement involves removing the entire intervertebral disc and replacing it with a synthetic implant. Whether performed in the cervical or lumbar region, this approach restores spinal stability and relieves persistent pain while preserving the full range of motion—something spinal fusion cannot offer. It’s especially beneficial for active individuals who want to maintain mobility after surgery.

Partial Disc Replacement (Nucleus Replacement)

In cases of early-stage disc degeneration, partial disc replacement may be suitable. This technique replaces only the inner core of the disc (nucleus pulposus), leaving the outer structure intact. It offers a less invasive option that retains much of the spine’s natural anatomy and can delay the need for more extensive surgery in the future.

Different types of artificial discs are used in disc replacement surgery, each designed to help the spine move naturally and reduce stress on surrounding areas. The most suitable type depends on factors such as a patient’s spinal health, age, and condition. At Max Hospitals, our doctors carefully assess these aspects before recommending the best option.

Composite Discs

These discs have a plastic spacer placed between two metal plates. This design is intended to reduce friction, which could slow down wear and tear over time. Many people choose them because they are considered a reliable option for long-term use.

Hydraulic Discs

Hydraulic discs have a special core that starts in a compressed form. Once inside the body, it absorbs fluid and expands, allowing the disc to act more naturally. This is designed to support smoother movement and may help reduce stiffness in the spine.

Elastic Discs

Elastic discs work similarly to composite discs but use a softer and more flexible material in the middle. This aims to provide a more natural movement and improved flexibility, which may be beneficial for everyday activities.

Mechanical Discs

Mechanical discs have two moving parts that allow controlled movement. They are usually made of metal or a mix of metal and ceramic. These discs are designed to function like a natural disc while staying strong and durable over time.

Disc replacement surgery may be suitable for individuals who meet the following conditions:

• Chronic neck or lower back pain due to a damaged spinal disc
• No relief from conservative treatments such as medication, physical therapy, or injections
• Adults typically between the ages of 18 and 60
• Good bone health with no significant osteoporosis
• Minimal or no spinal instability
• One or two affected disc levels (not multiple-level disease)
• No severe arthritis or major spinal deformities
• Overall good health and fitness for surgery and recovery
• No significant nerve compression requiring alternative surgical approaches
• Realistic expectations and a clear understanding of the procedure

Preparing for disc replacement surgery involves several important steps to support a smooth procedure and recovery. Here is what to expect:

Medical Evaluation

A doctor typically assesses overall health by reviewing medical history and carrying out a physical examination. 

Diagnostic Test

Imaging tests, such as X-rays or MRIs, are often performed to examine the condition of the spine and the affected disc. 

Medications 

Patients should inform their healthcare provider about all medicines and supplements being taken, as some may need to be adjusted before surgery to reduce any risks.

Diet and Hydration 

Eating light meals the day before surgery and staying hydrated is generally recommended. Food and drink are usually avoided after midnight before the procedure.

Smoking

Stopping smoking before surgery is advisable, as it can affect healing and increase the risk of complications.

Understanding the Procedure

A surgeon usually explains the type of disc replacement being considered, outlining what to expect before, during, and after the procedure. 

Knowing what to expect during disc replacement surgery can help ease your mind and prepare you for the surgery.

Anaesthesia

Before the surgery begins, general anaesthesia is administered to keep the patient unconscious and free from pain. Once it takes effect, a breathing tube may be placed to assist with breathing. Additionally, a thin, flexible tube (catheter) may be inserted in the bladder to drain urine during and after surgery. These measures help manage essential body functions while under anaesthesia.

Procedure

The surgical approach depends on the location of the affected disc and the overall treatment plan. Disc replacement is typically performed in the lower back or neck.

• Lumbar Disc Replacement (Lower Back): The surgeon makes a small cut in the lower back, gently moves aside muscles and tissues to reach the spine, removes the damaged disc, and inserts an artificial one to restore movement. Afterwards, the cut is closed with stitches or staples, and a protective bandage is applied.
• Cervical Disc Replacement (Neck): A small cut is made at the affected area of the neck. The surgeon carefully moves tissues to access the spine, removes the damaged disc, and replaces it with an artificial one. The cut is then closed, and a soft collar may be provided to support the neck during early recovery.

Recovering from disc replacement surgery involves several important steps to ensure proper healing.

Hospital Stay and Immediate Care

After surgery, patients are monitored in a recovery area until the effects of anaesthesia wear off. Early movement, such as standing and walking, is encouraged to promote blood flow and aid recovery. Hospital stays typically range from one to three days, depending on progress.

Pain Management and Incision Care

Some discomfort around the incision site and nearby muscles is common. Pain relief is provided through prescribed or over-the-counter medications. Keeping the incision clean and dry is crucial to prevent infection.

Activity Restrictions and Physical Therapy

Light activities may be resumed within a week, but heavy lifting, bending, or strenuous movements should be avoided for several weeks. Doctors may recommend starting gentle physical therapy to restore movement, strengthen muscles, and improve flexibility.

Follow-Up Appointments

The first visit is usually scheduled within two weeks post-surgery, with additional appointments in the following months to monitor healing.

Recovery Timeline

Recovery varies between individuals, but many return to daily activities, like walking and light tasks, within a week. Driving may be possible after a couple of weeks, depending on comfort and mobility. Full recovery, including more demanding activities, typically takes between six and twelve weeks.

Disc replacement surgery is generally considered safe, but like all procedures, it carries potential risks, including:

• Infection: There is a possibility of infection at the surgical site or surrounding areas. Many infections can be managed with antibiotics, but some may require additional treatment.
• Bleeding: Some bleeding can occur during or after the procedure. Significant blood loss is uncommon but may require medical attention.
• Nerve Damage: There is a risk of nerve injury near the surgical site, which could cause symptoms like numbness, tingling, or weakness. While rare, such injuries may have lasting effects.
• Adjacent Segment Degeneration: The spinal segments next to the treated area might experience increased stress, potentially leading to future issues.

How long does an artificial disc last?

Artificial discs are designed to last for 15 to 20 years or more, depending on factors such as material quality, patient activity levels, and proper post-surgery care.

Can disc replacement surgery be done at multiple levels of the spine?

In selected cases, multi-level disc replacement is possible, but it depends on the patient's spinal health and the surgeon’s recommendation.

Is disc replacement surgery covered by insurance?

Many insurance providers offer partial or full coverage for disc replacement surgery, but coverage varies based on policy terms and prior authorisation.

How does disc replacement surgery compare to spinal fusion in terms of recovery?

Disc replacement generally offers a faster recovery time and better spinal flexibility compared to fusion, which can limit movement.

Are there any weight restrictions for patients undergoing disc replacement surgery?

Yes, patients who are significantly overweight may face higher surgical risks and may be advised to lose weight before the procedure.

Can an artificial disc be replaced in the future if needed?

In rare cases where complications arise, revision surgery may be required to replace or adjust the artificial disc.

Will disc replacement surgery set off metal detectors at airports?

Artificial discs are usually made from medical-grade materials like titanium, which may occasionally trigger metal detectors, though many patients pass through without issues.

How soon can someone return to work after disc replacement surgery?

This depends on the type of work. Desk jobs may be resumed within 2–4 weeks, while physically demanding jobs may require a longer recovery period.

Is disc replacement surgery suitable for elderly patients?

Age is not the only factor; overall health, bone quality, and spinal stability are more important considerations for eligibility.

Will there be visible scarring after disc replacement surgery?

The incision is typically small, and scarring is minimal. Over time, the scar usually fades significantly.

Can disc replacement surgery improve posture?

By restoring spinal alignment and reducing pain, disc replacement can indirectly help improve posture.

Does the weather affect the artificial disc?

No, artificial discs are not sensitive to weather changes, although some patients may still experience general joint or muscle discomfort in cold weather.

Can women undergo disc replacement surgery during menopause?

Yes, but the hormonal changes and bone density considerations are assessed before recommending the procedure.

Is disc replacement surgery an outpatient procedure?

Disc replacement surgery is typically not an outpatient procedure. While some cervical disc replacements may be performed with shorter hospital stays, lumbar disc replacements usually require inpatient care. The length of hospital stay varies depending on the individual patient's health, the complexity of the surgery, and the specific surgical technique used.

What lifestyle changes are recommended after disc replacement surgery?

Maintaining a healthy weight, following a regular exercise routine, avoiding smoking, and practicing good posture can help preserve the success of the surgery.
