What Is Decompression Surgery?

Decompression surgery is a procedure performed to relieve pressure on spinal nerves or the spinal cord. This pressure can cause back pain, neck pain, numbness, weakness, or pain that travels down the arms or legs.

In Singapore, decompression surgery is commonly recommended for patients whose symptoms do not improve with medication, physiotherapy, or injections, and whose daily activities or quality of life are affected.

The aim of decompression surgery is simple:
👉 to create more space for the nerves so they can function properly again.

Why Is Decompression Surgery Needed?

As we age, natural wear and tear of the spine is common. In Singapore’s ageing population, spinal conditions are increasingly seen in adults over 50, though younger patients can also be affected.

Common reasons patients require this surgery include:

• Spinal stenosis (narrowing of the spinal canal)

• Slipped or herniated discs

• Bone spurs caused by arthritis

• Thickened spinal ligaments

When nerves are compressed, patients may experience:

• Persistent back or neck pain

• Pain radiating to the arms or legs

• Numbness or tingling

• Muscle weakness

• Difficulty walking or standing for long periods

How Does Decompression Surgery Work?

During the surgery, the surgeon removes the structures that are pressing on the nerves. This may include:

• A portion of bone

• Part of a slipped disc

• Thickened ligaments

By relieving this pressure, inflammation is reduced and nerve signals can travel more normally, leading to pain relief and improved movement.

Common Types of Decompression Surgery

The type of decompression surgery depends on the cause and location of nerve compression.

Laminectomy

A small part of the bone at the back of the spine is removed to widen the spinal canal.

Discectomy

Part of a slipped disc is removed to relieve pressure on a nerve.

Foraminotomy

The openings where nerves exit the spine are enlarged to reduce nerve compression.

Our specialist will recommend the most suitable procedure based on your condition and imaging results such as MRI scans.

What Happens During Decompression Surgery in Singapore?

• Performed under general anaesthesia

• Surgery usually takes 1 to 3 hours

• Minimally invasive techniques may be used where appropriate

• Patients are closely monitored by trained surgical and nursing teams

Many decompression surgeries in Singapore are done using modern techniques that aim to:

• Minimise muscle damage

• Reduce blood loss

• Speed up recovery

Recovery After Decompression Surgery

Recovery time varies, but most patients can expect:

• Walking within 24 hours after surgery

• Hospital stay of 1 to 3 days, depending on the procedure

• Gradual improvement in pain, numbness, or weakness

• Return to light activities within a few weeks

Physiotherapy is commonly recommended as part of recovery to restore strength and flexibility.

Benefits of Decompression Surgery

For suitable patients, decompression surgery can provide:

• Significant pain relief

• Improved walking and mobility

• Reduced numbness and tingling

• Better overall quality of life

Early treatment can also help prevent permanent nerve damage.

Is Decompression Surgery Safe?

Decompression surgery is a commonly performed and well-established procedure in Singapore. As with all surgeries, there are risks such as infection or bleeding, but these are generally low when surgery is performed by an experienced spine specialist.

Our surgeon will discuss the benefits, risks, and expected outcomes before surgery.

When Should You See a Spine Specialist?

You should consider seeing a specialist in Singapore if you have:

• Persistent back or neck pain lasting more than a few weeks

• Pain spreading to the arms or legs

• Weakness, numbness, or balance problems

• Symptoms that do not improve with conservative treatment

Early assessment allows for timely treatment and better outcomes.

 

Decompression surgery is an effective treatment option for patients with nerve compression that does not improve with conservative care. In Singapore, advances in surgical techniques allow many patients to recover faster and return to daily activities with reduced pain.

If you are experiencing ongoing symptoms, consult our Spine Specialist for a detailed assessment and find out whether decompression surgery is recommended.
