Does a herniated disc require surgery?
Hello Doctor: I am 41 years old and about three weeks ago, I experienced severe pain in my lower back that radiated down to my left buttock, the back of my left thigh, and my left heel.
After undergoing an MRI, I was diagnosed with a herniated disc at the L5-S1 level, along with some stenosis.
The MRI showed that the herniated nucleus pulposus has extruded posteriorly, compressing the spinal nerve, and the extent of the herniation appears significant (there is no spondylolisthesis, subluxation, or dislocation; my height is 176 cm and my weight is 70 kg).
Today, three weeks later, the pain has lessened, but the numbness in my left heel and reduced tactile sensation seem to have improved only slightly.
I have the following questions: 1.
What is the likelihood and possibility of the extruded nucleus pulposus being absorbed by the body if it is not surgically removed? 2.
If the nucleus pulposus is not removed and later undergoes calcification, what is the probability of it continuing to compress the nerve and the likelihood of needing surgery? (If there are no specific data, please provide your recommendations based on your clinical experience.) 3.
If I choose not to undergo surgery, is there a chance for recovery? 4.
If surgery is necessary, which approach would be more suitable: endoscopic discectomy, microscopic discectomy with decompression, or microscopic spinal fusion? Thank you for your time!

The nucleus pulposus of a herniated disc still has a significant chance of being reabsorbed on its own.
In most cases, the symptoms of nerve compression will improve over time, although there is a small possibility of worsening.
If the symptoms of nerve compression persist after six weeks and there is weakness in the left lower limb, surgery is recommended.
As for which surgical procedure is more appropriate, a personal examination and MRI evaluation will be necessary to make that determination.

When it comes to a ruptured disc, particularly in your case with an L5-S1 herniation, the decision to undergo surgery is multifaceted and depends on various factors, including the severity of symptoms, the degree of nerve compression, and the overall impact on your quality of life. Here are some insights based on your questions:
1. Possibility of Self-Absorption of the Herniated Nucleus: The body can sometimes reabsorb herniated disc material, particularly if it is not severely compressing the nerve. Studies suggest that a significant percentage of patients experience some degree of resorption over time, which can lead to symptom improvement. However, the exact percentage varies widely and is influenced by individual factors such as age, overall health, and the size of the herniation. While some patients report improvement without surgical intervention, others may not experience significant changes.
2. Risk of Calcium Formation and Continued Nerve Compression: If the herniated material does not get reabsorbed, there is a risk that it could calcify over time, potentially leading to chronic nerve compression. This could increase the likelihood of requiring surgical intervention in the future. While specific statistics on this are scarce, clinical experience suggests that persistent symptoms, such as numbness and pain, may indicate that surgical options should be considered sooner rather than later to prevent further complications.
3. Chances of Recovery Without Surgery: Many patients with a herniated disc can recover without surgery, especially if they engage in appropriate conservative treatments such as physical therapy, pain management, and lifestyle modifications. The success of non-surgical treatment often depends on the severity of the symptoms and the degree of nerve involvement. If your symptoms are improving, there is a chance that continued conservative management could lead to further recovery.
4. Surgical Options: If surgery is deemed necessary, the choice between endoscopic discectomy, microscopic discectomy, or spinal fusion will depend on several factors, including the extent of the herniation, your overall health, and the surgeon's expertise.
- Endoscopic Discectomy: This minimally invasive procedure allows for the removal of herniated disc material through small incisions. It typically results in less postoperative pain and quicker recovery times.
- Microscopic Discectomy: This is a more traditional approach that uses a microscope to guide the removal of the herniated disc material. It is effective and has a good success rate.
- Spinal Fusion: This is generally reserved for cases where there is significant instability or degeneration in addition to the herniation. It involves fusing the affected vertebrae together, which can limit motion but may be necessary in certain situations.
In conclusion, the decision to proceed with surgery for a ruptured disc should be made collaboratively with your healthcare provider, considering your specific symptoms, lifestyle, and preferences. It is essential to weigh the potential benefits and risks of surgery against the possibility of recovery through conservative management. If you have not already done so, seeking a second opinion from a spine specialist may provide additional insights and help you make an informed decision about your treatment options. Always remember that early intervention can often lead to better outcomes, so staying proactive about your health is crucial.
