Post-Discectomy Sciatica: Pain and Recovery Challenges - Neurosurgery

Post-operative nerve pain from the groin to the right leg, resulting in inability to walk?


Hello Doctor: I am currently 49 years old.
On August 21, 2020, I underwent surgery at a hospital in Taoyuan.
The surgical procedures included: lumbar interbody fusion with posterior fusion and fixation, laminectomy for decompression, lumbar discectomy, implantation of dynamic stabilization rods, and implantation of vertebral body struts.
As of October 3, 2020, it has been one and a half months since the surgery, and I am still experiencing sciatic nerve pain radiating down my right thigh and calf.
During follow-up visits, the doctor repeatedly examined me with MRI and X-rays, and the results appeared normal.
The doctor mentioned that the inflammation of the nerve root could be due to the position during surgery and that it requires time to recover.
I researched my current symptoms, which closely resemble sciatic nerve pain.
I would like to ask: 1.
After a discectomy, is it common to still experience issues with sciatic nerve pain? 2.
I have been told that my bone density is comparable to that of a 70- to 80-year-old.
3.
This is my third lumbar discectomy, and it has been exactly three years since the second surgery (which was in August 2017).
4.
If the issue is related to the sciatic nerve, is it possible that I may require another surgery? Thank you for your patience in reading and explaining my concerns.
Thank you.

Hello: Although you have worked hard to write a lot, I need more information for assessment and reasoning.
Since I cannot see the patient or the imaging in person, I can only suggest that if the original surgeon is unable to improve your symptoms and you have other thoughts regarding their explanation, you may consider consulting another expert in spinal neurosurgery nearby.
As the saying goes: "A gentleman's fate is determined by his master’s fortune!" Wishing you all the best.

More Info


Post-discectomy sciatica is a common issue that many patients face after undergoing spinal surgery, particularly for conditions like herniated discs. Your situation, having undergone multiple surgeries, including a spinal fusion and discectomy, presents unique challenges in recovery and pain management.
Firstly, it is important to understand that experiencing sciatica or nerve pain after surgery is not uncommon. The surgical procedure itself, while aimed at relieving pressure on the nerves, can sometimes lead to inflammation or irritation of the surrounding tissues, including the nerve roots. This inflammation can manifest as pain radiating down the leg, similar to what you are experiencing. The fact that your MRI and X-ray results appear normal is a positive sign, indicating that there are no new structural issues, but it does not eliminate the possibility of post-operative inflammation or nerve irritation.

1. Post-Surgery Sciatica: Yes, it is possible to experience sciatica after a discectomy. The surgery can lead to temporary nerve irritation or inflammation, which may take time to resolve. In some cases, scar tissue can form around the nerve roots, leading to persistent pain. This is often referred to as post-operative adhesive arachnoiditis or nerve root irritation. It is essential to give your body time to heal, as nerve recovery can be a slow process, sometimes taking several months.
2. Bone Density Concerns: You mentioned having low bone density, which can complicate recovery. Osteoporosis or low bone density can increase the risk of complications during and after surgery, including delayed healing and increased pain. It is crucial to manage your bone health through appropriate dietary measures, supplementation (like calcium and vitamin D), and possibly medications if recommended by your healthcare provider. Engaging in low-impact exercises, as tolerated, can also help strengthen the bones and improve overall recovery.

3. Multiple Surgeries: Having undergone three surgeries in a relatively short period can lead to cumulative effects on your body, including increased scar tissue formation and changes in the biomechanics of your spine. Each surgery carries risks, and the more procedures performed, the higher the likelihood of complications such as chronic pain syndromes.

4. Need for Further Surgery: Whether or not you need another surgery depends on several factors, including the persistence of your symptoms, the effectiveness of conservative treatments, and the clinical judgment of your healthcare team. Before considering another surgical intervention, it is advisable to explore conservative management options such as physical therapy, pain management strategies (including medications and possibly nerve blocks), and lifestyle modifications.
In conclusion, it is vital to maintain open communication with your healthcare providers about your symptoms and concerns. They may recommend a multidisciplinary approach, involving physical therapy, pain management specialists, and possibly a consultation with a neurologist if nerve pain persists. Recovery from spinal surgery can be a long and challenging journey, but with the right support and management strategies, many patients can achieve significant improvements in their quality of life. Remember to be patient with yourself and allow your body the time it needs to heal.
