Lumbar Discectomy
A lumbar discectomy is a type of spinal surgery used to treat symptoms caused by a herniated disc in the lower back. For some people, a lumbar disc herniation can place pressure on nearby spinal nerves, contributing to symptoms such as leg pain, numbness, weakness, or persistent back pain.
Understanding what a lumbar discectomy involves, why it may be considered and how it fits within the broader range of treatment options can help patients make informed decisions about their care.
At Rivercity Brain & Spine, patients are cared for by Dr Joseph Garcia Redmond, a specialist neurosurgeon with subspecialty training in minimally invasive spine surgery. Dr Garcia Redmond trained in neurosurgery at major hospitals in Australia and New Zealand before completing further fellowship training internationally, bringing this experience to a patient-centred approach that is safe, effective and compassionate. Assessment and treatment recommendations are based on each person's individual circumstances, including their symptoms, imaging results, medical history and overall health.
What is a Lumbar Discectomy?
A lumbar discectomy is a surgical procedure that involves removing part of a damaged intervertebral disc that is pressing on a nerve root in the lumbar spine. The lumbar spine consists of five vertebrae in the lower back. Between these vertebrae are intervertebral discs, which act as shock absorbers and help allow movement within the spinal column. Each disc has a soft inner component surrounded by a tougher outer layer known as the annulus fibrosus.
When the outer layer becomes damaged, disc material can protrude or leak out. This is commonly described as a herniated disc, lumbar disc prolapse or disc herniation. In some cases, the displaced disc material can extend into the spinal canal and compress nearby spinal nerves.
A lumbar discectomy aims to remove the disc fragments causing nerve compression while preserving as much of the healthy disc structure as possible.
Why Might Lumbar Discectomy Surgery Be Considered?
A herniated lumbar disc does not always require surgery. Many people with a lumbar disc herniation can be managed with nonoperative treatment, depending on the severity of their symptoms and how they respond over time.
Conservative treatment options may include:
Physical therapy
Activity modification
Pain medicines
Targeted exercises
For some patients, symptoms may improve with these approaches. However, lumbar discectomy surgery may be considered when symptoms continue despite appropriate nonoperative treatment, or when there are specific clinical reasons for surgical intervention.
A specialist assessment may be recommended when symptoms include ongoing severe pain, significant weakness, progressive neurological deficits, or changes affecting bowel function or bladder control. These symptoms can indicate pressure affecting the nervous system and require timely medical assessment.
What to Expect
Consultation
Your symptoms, medical history and imaging are reviewed, and treatment options, including the advantages and risks of lumbar discectomy, are discussed.
Procedure
Lumbar discectomy is generally performed under general anaesthetic. A small incision is made in the lower back, through which the surgeon accesses the affected disc material while aiming to minimise disruption to surrounding structures.
Planning
If lumbar discectomy is considered appropriate, a personalised surgical plan is developed based on the location and size of the disc herniation and your individual anatomy.
Recovery
Recovery timelines vary between patients and depend on individual health factors and the nature of the disc problem. Some patients may return home the same day, while others require a longer period of monitoring. Your care team will discuss realistic expectations, including wound care and a gradual return to activity.
Lumbar Spine Surgery for Nerve Compression
The decision between surgical vs nonoperative treatment depends on several factors, including:
The location and size of the disc herniation
The severity and duration of symptoms
The impact on daily activities
Findings from clinical examination and imaging
Overall health and medical history
Imaging such as an MRI or CT scan may help assess the lumbar spine and identify whether a herniated disc is affecting the nerve root or spinal nerves. Lumbar spine surgery is not appropriate for every person with back pain. A thorough assessment helps determine whether surgery may be suitable or whether other treatments should continue to be explored.
How is a Lumbar Discectomy Performed?
A lumbar discectomy is usually performed under general anaesthetic. There are different surgical approaches depending on the individual condition, anatomy and surgeon assessment.
During the procedure, a small skin incision may be made in the lower back. The surgeon carefully accesses the affected area while aiming to minimise disruption to surrounding structures, including the back muscles and supporting tissues.
In some cases, minimally invasive techniques may be used. These approaches can involve specialised instruments and a smaller incision compared with some traditional open surgery techniques.
A lumbar microdiscectomy is one example of a minimally invasive approach that uses magnification and specialised instruments to remove disc material affecting a nerve.
The exact surgical approach depends on factors such as the location of the herniated disc, the anatomy of the lumbar spine and the patient’s individual circumstances.
What Happens During Recovery After Lumbar Discectomy Surgery?
Some patients may be able to return home on the same day, while others may require a longer period of monitoring depending on their circumstances.
After surgery, follow-up care may include:
Wound care instructions
Gradual return to activity
Physical therapy where appropriate
Monitoring of symptoms and recovery progress
Patients are generally provided with guidance about caring for the surgical site, including keeping the wound dry as it heals.
What Are the Risks of Lumbar Discectomy?
Like all surgical procedures, lumbar discectomy involves potential risks and complications. These can vary depending on individual health factors and the specific circumstances of the surgery.
Possible complications may include:
Infection
Blood clots
Bleeding
Dural tear
Nerve injury or nerve damage
Recurrence of disc problems, including recurrent disc herniation
Persistent or returning pain
General complications associated with surgery can also include reactions related to anaesthesia, changes in blood pressure and other health considerations. Certain medications, such as blood thinners, and existing health problems may influence surgical planning. Patients should discuss their medical history, medications, and any supplements, including herbal supplements, with their healthcare team before surgery.
Can a Lumbar Disc Herniation Happen Again?
A recurrent disc herniation can occur in some patients following lumbar discectomy. This means disc material may herniate again at the same level or another level of the lumbar spine.
If recurrent symptoms develop, further assessment may be needed to understand the cause and determine appropriate management. In some situations where there is spinal instability or more extensive degeneration, additional procedures such as a spinal fusion may be considered. However, this depends on individual clinical findings and is not required for every patient undergoing spine surgery.
How Does Lumbar Discectomy Compare With Other Spine Surgery Options?
Lumbar discectomy is one type of spine surgery designed for a specific problem: relieving pressure on a nerve caused by disc material.
Other surgical approaches may be considered for different spinal conditions. For example, spinal fusion may be used in selected cases where stabilisation of the spinal column is required.
The most appropriate treatment depends on the underlying condition, anatomy and clinical assessment. Surgery is generally considered as part of a broader approach that may include rehabilitation, physical therapy and other treatments.
Do You Need a Referral to See a Specialist?
In Australia, a referral from a GP is generally required to see a specialist neurosurgeon, including for an initial consultation regarding a lumbar discectomy or other spine surgery.
A referral allows your GP to share relevant medical history, previous imaging and other clinical information with the specialist ahead of your appointment. This helps ensure that the consultation is as informed and efficient as possible.
