Spine Surgery and Risks

Deciding whether to proceed with spine surgery can feel challenging. Surgery for back, neck or spinal conditions is usually considered when symptoms are severe, when nerve compression is causing significant pain or weakness, or when non-surgical treatments have not provided enough relief.

Professor Nasir Quraishi, Consultant Spinal Surgeon in Nottingham, helps patients understand their diagnosis, treatment options and the potential risks and benefits of spine surgery. The aim is to support informed, shared decision-making so that each patient can choose the most appropriate treatment for their condition.

Spine surgery does not guarantee improvement for every patient. However, for carefully selected patients, surgery may help relieve pain, reduce nerve pressure, improve function and support a better quality of life.

When Is Spine Surgery Considered?

Spine surgery may be considered for conditions such as:

  • Sciatica caused by a slipped disc or disc prolapse
  • Spinal stenosis causing leg pain, numbness or walking difficulty
  • Nerve compression in the neck or lower back
  • Spinal instability
  • Scoliosis or adult spinal deformity
  • Spinal fractures
  • Spinal infection
  • Spinal tumours or spinal metastases
  • Recurrent or persistent symptoms after previous spine surgery

In many cases, non-surgical treatment is recommended first. This may include physiotherapy, pain medication, activity modification, spinal injections or rehabilitation. Surgery is usually considered when symptoms continue despite appropriate conservative treatment or when there are concerning neurological symptoms.

Potential Benefits of Spine Surgery

The main aim of most spine surgery is to relieve symptoms caused by structural problems in the spine, such as pressure on nerves, instability, deformity or damage to spinal tissues.

For some patients, successful spine surgery may lead to:

  • Reduced back, neck, arm or leg pain
  • Improved walking ability and mobility
  • Reduced nerve pain, numbness or weakness
  • Improved ability to remain active
  • Better physical fitness and independence
  • Improved mood and quality of life
  • Reduced reliance on pain medication
  • Fewer medication-related side effects
  • Improved ability to return to work
  • Improved productivity and daily function

It is important to understand that not all patients experience significant pain relief after surgery. Predicting who will benefit most can be difficult, and outcomes depend on the diagnosis, severity of symptoms, general health, imaging findings and the type of surgery being considered.

Risks of Spine Surgery

Most patients undergoing spine surgery do not experience serious complications. However, all surgery carries risk. The level of risk varies depending on the patient, the spinal condition, the type of operation and any other medical conditions.

General risks of spine surgery may include:

  • Reaction to anaesthesia or medications
  • Bleeding
  • Infection
  • Blood clots in the legs or lungs
  • Heart attack or stroke
  • Persistent pain after surgery
  • Recurrent disc herniation
  • Nerve injury
  • Weakness, numbness or ongoing nerve pain
  • Paralysis, although this is rare
  • Sexual dysfunction
  • Loss of bowel or bladder control
  • Need for further surgery

Your individual risks should be discussed with your spine surgeon before making a decision. This discussion should include the likely benefits of surgery, the alternatives to surgery, the expected recovery process and the risks that are most relevant to your condition.

Risks and Benefits of Different Types of Spine Surgery

Different spinal procedures have different aims, benefits and risks. The most appropriate operation depends on the diagnosis, symptoms, imaging findings and overall health of the patient.

Spinal Fusion

Spinal fusion is a procedure that joins two or more vertebrae together to reduce movement and stabilise the spine. It may be recommended for spinal instability, deformity, certain fractures, severe degeneration or some complex spinal conditions.

The aim of spinal fusion is to reduce painful movement, improve stability and relieve nerve irritation where appropriate. For many patients, reduced movement at the fused level does not significantly limit everyday activity.

Specific risks of spinal fusion may include:

  • Failure of the bones to fuse fully
  • Implant-related problems
  • Infection
  • Ongoing pain
  • Adjacent segment degeneration
  • Need for further surgery

Smoking can increase the risk of incomplete fusion and post-operative infection. Patients who smoke are usually advised to stop before surgery to improve healing and reduce complications.

Laminectomy and Laminotomy

A laminectomy is a decompression procedure that involves removing part of the vertebral bone, and sometimes thickened ligaments or bone spurs, to relieve pressure on the spinal nerves.

It is commonly used to treat spinal stenosis, where narrowing of the spinal canal causes leg pain, numbness, weakness or difficulty walking.

Potential benefits of laminectomy may include:

  • Reduced leg pain
  • Improved walking distance
  • Reduced nerve compression
  • Improved mobility and function

Potential risks may include:

  • Persistent symptoms
  • Infection or bleeding
  • Nerve injury
  • Dural tear or spinal fluid leak
  • Reduced spinal stability in some patients
  • Need for spinal fusion if instability is present or develops later

Foraminotomy

A foraminotomy is a procedure that widens the opening where a nerve root exits the spine. This can reduce pressure on the nerve and may help symptoms such as arm pain, leg pain, numbness or weakness.

Potential benefits may include:

  • Relief of nerve compression
  • Reduced arm or leg pain
  • Improved nerve-related symptoms

Potential risks may include:

  • Persistent pain or numbness
  • Recurrent nerve compression
  • Reduced spinal stability in some cases
  • Need for further surgery

Discectomy

A discectomy involves removing part of a damaged or prolapsed disc that is pressing on a nerve. It is commonly performed for sciatica caused by a lumbar disc prolapse, or for nerve compression in the neck or lower back.

Discectomy may be performed through a traditional incision or using minimally invasive techniques, depending on the patient and the condition being treated.

Potential benefits may include:

  • Reduced leg or arm pain
  • Relief of nerve pressure
  • Improved mobility and function
  • Faster recovery in selected patients

Potential risks may include:

  • Recurrent disc herniation
  • Persistent nerve pain
  • Infection or bleeding
  • Dural tear or spinal fluid leak
  • Need for further surgery

Artificial Disc Replacement

Artificial disc replacement involves removing a damaged spinal disc and replacing it with an artificial disc. The aim is to relieve pain while preserving movement at that spinal level.

It may be considered in selected patients as an alternative to spinal fusion.

Potential benefits may include:

  • Pain relief
  • Preservation of spinal movement
  • Shorter recovery time in some patients compared with fusion

Potential risks may include:

  • Device movement or failure
  • Wear of the artificial disc over time
  • Persistent pain
  • Nerve injury
  • Need for revision surgery

What Is the Main Risk of Back Surgery?

For many patients, the main concern is that surgery may not provide the expected level of pain relief or functional improvement. This can be difficult to predict because spinal pain is complex and may be influenced by several factors, including nerve damage, degeneration, general health, muscle conditioning and pain sensitivity.

A detailed consultation, examination and review of imaging can help identify whether surgery is likely to help. Talking openly with your surgeon about realistic expectations is an important part of deciding whether surgery is right for you.

Making an Informed Decision About Spine Surgery

Before deciding on spine surgery, patients should understand:

  • Their diagnosis
  • Why surgery is being considered
  • The non-surgical alternatives
  • The expected benefits
  • The possible risks
  • The recovery process
  • The chance that symptoms may persist
  • Whether further surgery may be needed

Professor Quraishi will discuss these issues with you and help you understand whether surgery is appropriate for your condition.
