Lumbar Decompression

What is Lumbar Decompression?

Lumbar decompression is a type of surgery to relieve pain caused by nerve root pinching. This pinching can occur for various reasons, including a herniated disc, spinal stenosis, or a tumour.


Lumbar decompression surgery aims to relieve pain, numbness, tingling, or weakness in the legs and lower back. 


Who is Suitable for Lumbar Decompression?

As for who is suitable for lumbar decompression, the procedure is usually considered for patients who have persistent pain, weakness, or numbness in their lower back or legs that severely affects their quality of life and does not improve with non-surgical treatments (like physical therapy or medication). It is typically recommended for patients with conditions like:

  • Lumbar disc herniation.
  • Lumbar spinal stenosis.
  • Degenerative disc disease.
  • Sciatica.


Benefits of Lumbar Decompression

  • Pain Relief: Lumbar decompression surgery can significantly reduce or eliminate chronic back and leg pain that has not responded to non-surgical treatments.
  • Improved Mobility: With alleviating pain, patients often experience increased mobility, enabling them to return to daily activities and live more actively.
  • Decreased Reliance on Pain Medication: Successful lumbar decompression surgery can lessen the need for long-term use of pain medication, which can have various side effects when used chronically.
  • Improved Quality of Life: Lumbar decompression can enhance a patient's overall quality of life by relieving chronic pain and improving mobility.


Types of Lumbar Decompression

There are different types of lumbar decompression surgeries, including:

  • Laminectomy: This is the most common type of lumbar decompression surgery. It involves removing the part of the vertebra that covers the spinal canal (the lamina) to create more space for the nerves.
  • Discectomy: This procedure involves removing a portion of a disc to relieve pressure on a nerve.
  • Foraminotomy: This procedure involves enlarging the foramen (the opening for the nerve roots to exit the spinal canal) to increase the size of the nerve pathway.
  • Laminoplasty: This is mostly performed on the neck (cervical spine). It opens up space within the spinal canal by creating a hinge on the lamina.
  • Facetectomy: This procedure involves removing a facet joint that is causing nerve compression.
  • Indirect: Insertion of an intervertebral spacer/cage/arthroplasty can decompress the canal's neural foramen or lateral recesses. 


Alternative Options to Lumbar Decompression

Before considering surgery, various non-surgical treatments are typically attempted. These may include:

  • Physical Therapy: Exercises and stretches under the supervision of a physiotherapist can often help alleviate symptoms.
  • Medication: Over-the-counter pain relievers, nonsteroidal anti-inflammatory drugs (NSAIDs), or prescription painkillers may help manage pain. Interventional Procedures: Epidural steroid injections, nerve blocks, and other interventional pain management procedures, such as radio-frequency ablation, can also be considered.
  • Lifestyle Changes: Maintaining a healthy weight, avoiding activities that exacerbate symptoms, practising good posture, and incorporating regular low-impact exercise into the routine can be helpful.
  • Spinal Cord Stimulation involves implanting a device that sends low-level electrical signals to the spinal cord or specific nerves to block pain signals from reaching the brain.


Preparation for Lumbar Decompression

  • Medical Evaluation: You'll undergo a thorough medical evaluation to ensure you're in the best possible health before the procedure. This might include blood tests, heart tests, and a review of your medications.
  • Medication Management: Some medications might need to be discontinued before surgery, especially those that could increase the risk of bleeding. Discuss all your medications, including over-the-counter drugs and supplements, with your doctor.
  • Smoking Cessation: If you smoke, it's highly recommended that you quit before surgery, as smoking can interfere with your healing and recovery and increase the risk of complications.
  • Fasting: You'll likely need to avoid eating or drinking for a certain period before the procedure.
  • Pre-surgical Physiotherapy: Some surgeons recommend a course of physiotherapy to strengthen the back muscles and improve recovery outcomes.


Lumbar Decompression Procedure

  • Anaesthesia: You will be given general anaesthesia, so you'll be asleep and not feel pain during the procedure.
  • Indwelling Catheter (IDC): A bladder tube will be placed to allow emptying your bladder before and during surgery. This will be removed one day after the operation.
  • Positioning: Your surgeon and the theatre team will position you on the surgical table face-down. 
  • Incision: The surgeon will make an incision in your back over the nerve compression area.
  • Decompression: The surgeon will then remove the source of compression—this could be part of a disc, a bone spur, or part of a vertebra.
  • Closure: The surgeon will close the incision with sutures once the decompression is complete.
  • Recovery: You're then taken to a recovery room and monitored as you wake from the anaesthesia. You will then be transferred to a hospital room before discharge home.


Lumbar Decompression Recovery Plan

  • Hospital Stay: You might need to stay in the hospital for up to a few days after surgery.
  • Pain Management: Your medical team will work with you to manage your pain effectively, likely with medications.
  • Physical Therapy: You'll be encouraged to move around soon after the surgery. You might also start a physiotherapy program to strengthen your back and improve your flexibility.
  • Activity Modification: In the early stages of recovery, you'll be advised to avoid activities that strain your back, such as heavy lifting and strenuous exercise. Gradually, you'll be able to return to normal activities.
  • Follow-up Appointments: You'll have follow-up appointments with your surgeon to monitor your progress and ensure you're healing properly.
  • Healthy Lifestyle: Maintaining a healthy lifestyle, including a balanced diet and regular exercise, can help support your recovery and overall spine health.


Lumbar Decompression Prognosis

The prognosis for lumbar decompression surgery is generally good, with many patients experiencing significant relief from symptoms.

  • Pain Relief: Many patients experience a significant reduction in pain following lumbar decompression. Studies indicate that up to 80-90% of patients will notice an improvement in their pain levels.
  • Improved Mobility: Patients typically have increased mobility post-surgery, which can improve their quality of life.
  • Long-Term Outcomes: Long-term outcomes can vary and depend on factors such as the patient's age, overall health, other diseases, and the severity of the spinal problem. Recurrent disc protrusions occur at a rate of approximately 5% in the first year and a further 1% every year following. 


Lumbar Decompression Risks

As with any surgery, lumbar decompression surgery carries potential risks, which may include:

  • General Anesthesia Risks
  • Bleeding
  • Nerve Damage
  • Dural Tear
  • Recurrent or Continued Symptoms
  • Blood Clots
  • Infection


What if Lumbar Decompression is Delayed?

If lumbar decompression surgery is delayed, the patient may continue to experience pain, which can interfere with daily activities and quality of life. Symptoms such as numbness, tingling, or weakness in the legs or arms can worsen over time.


If nerve compression is severe or prolonged, it can lead to permanent nerve damage.


If pain and discomfort increase, mobility can decrease over time, leading to a more sedentary lifestyle and associated health risks.


Please note that deciding to have surgery is a complex decision that a qualified spinal surgeon must make. The decision will consider the severity of symptoms, the risks and benefits of surgery, and the patient's overall health.
