When conservative treatments fail to relieve the debilitating pain of a herniated disc, herniated disc surgery becomes a viable option for many patients. A herniated disc occurs when the soft inner material of a spinal disc pushes through a crack in the outer layer, potentially compressing nearby nerves. According to the American Association of Neurological Surgeons, approximately 90% of herniated disc cases resolve without surgery. However, when conservative treatments fail after 6-12 weeks, surgical intervention may be necessary.
This guide explores various surgical approaches, helping you understand which procedure might be right for your specific condition. From minimally invasive techniques to complex spinal reconstructions, modern herniated disc surgery offers multiple pathways to pain relief and restored mobility.
Types of Herniated Disc Surgery
1. Discectomy (Open Approach)
Traditional discectomy involves a larger incision to access the herniated disc directly. While more invasive than microscopic techniques, open discectomy may be necessary for complex cases involving significant nerve compression or when multiple disc levels require treatment. This approach provides excellent visualisation and access for thorough decompression.
2. Microdiscectomy
Microdiscectomy is the gold standard for herniated disc surgery, particularly in the lumbar spine. This minimally invasive procedure uses a surgical microscope to remove the herniated portion of the disc through a small incision. Studies show success rates of 85-95% for leg pain relief. The procedure typically takes 1-2 hours and allows for same-day or overnight hospital stays.
3. Endoscopic Discectomy
Endoscopic discectomy utilises a thin, flexible tube with a camera to visualise and remove herniated disc material. This ultra-minimally invasive approach requires only a small puncture wound, resulting in minimal tissue damage and faster recovery. The procedure is particularly effective for contained disc herniations, offering excellent visualisation of the surgical site.
4. Laminectomy & Laminotomy
Laminectomy involves removing the entire lamina (back part of the vertebra) to access the herniated disc, while laminotomy removes only a portion. These procedures are often combined with a discectomy when additional space is needed to remove disc material safely. The choice between these approaches depends on the extent of nerve compression and anatomical considerations.
5. Spinal Fusion
Spinal fusion may be recommended when herniated disc surgery requires the removal of significant disc material, potentially compromising spinal stability. This procedure permanently connects two or more vertebrae using bone grafts and hardware. While fusion eliminates motion at the treated level, it provides excellent long-term stability and pain relief for appropriate candidates.
6. Anterior Cervical Discectomy and Fusion (ACDF)
Anterior cervical discectomy and fusion is the preferred approach for cervical herniated discs. The surgeon accesses the disc from the front of the neck, removes the herniated material, and typically places a bone graft or cage to maintain disc height. This procedure has high success rates for both arm pain and neurological symptoms.
7. Artificial Disc Surgery
Artificial disc surgery, also known as lumbar disc arthroplasty, preserves motion at the treated level by replacing the damaged disc with a mechanical device. This option is suitable for younger patients with single-level disc disease who want to maintain spinal flexibility. Long-term studies show comparable outcomes to fusion with preserved motion.
8. Foraminotomy
Foraminotomy is used when a herniated disc or bone spurs narrow the foramen. It is a procedure that enlarges the neural foramen, the opening where nerve roots exit the spine.
It helps relieve nerve compression without removing large portions of the lamina. This surgery can be performed as a minimally invasive/endoscopic procedure that preserves spinal motion and relieves radiating nerve pain.
9. Corpectomy
Corpectomy is used for severe compression due to herniation, fractures, bone disease, or spinal tumours. It is a more complex procedure involving the removal of part or all of the vertebral body along with discs above or below it. This is often followed by fusion to restore stability. Corpectomy provides strong decompression for the spinal cord and nerves, especially in cervical spine conditions.
10. Kyphoplasty
Kyphoplasty is primarily used to treat vertebral compression fractures, which may coexist with disc issues. This involves inserting a balloon into the fractured vertebra, inflating it, and filling it with bone cement. It provides benefits such as restoring vertebral height, reducing pain, and stabilising fractures. While not a direct disc surgery, it is relevant when a herniation is associated with spinal fragility or trauma.
Conclusion
Herniated disc surgery offers effective relief for patients who haven’t responded to conservative treatment. From minimally invasive microdiscectomy to complex fusion procedures, modern surgical options provide tailored solutions for various disc conditions.
The key to successful outcomes lies in proper patient selection, choosing the appropriate surgical technique, and following comprehensive rehabilitation protocols. With proper treatment and rehabilitation, excellent outcomes are achievable.

Frequently Asked Questions
Q. 1 How do I know if I need herniated disc surgery?
Surgery is typically considered when conservative treatments fail after 6-12 weeks, or immediately if you experience severe neurological symptoms like weakness or bowel/bladder dysfunction.
Q. 2 What is the success rate of herniated disc surgery?
Success rates vary by procedure but generally range from 85-95% for pain relief, with microdiscectomy showing the highest success rates for appropriate candidates.
Q3. Can herniated discs recur after surgery?
Recurrence rates are approximately 5-10% for most procedures. Following post-operative guidelines and maintaining good spine health can minimise this risk.
Q. 4 Can a herniated disc heal without surgery?
Yes. Most herniated discs improve naturally with rest, physiotherapy, medications, and lifestyle changes.
