Spinal Fusion Surgery: Key Insights and FAQs

What is spinal fusion surgery?

Hello, I am the one with the lumbar disc herniation at L2-L4.
I have received your response, thank you! May I ask: 1.
Why is it best not to get pregnant? 2.
It has been over two years since the surgery, but my body still feels very weak, and I experience leg soreness and a sense of weakness.
Why is this still happening? Are these symptoms of a pathological condition? Is there a risk of recurrence? 3.
Among general lumbar disc surgery, lumbar microdiscectomy, and endoscopic surgery, which one is a spinal fusion surgery? 4.
Which type of surgery for L2-L4 will ensure that the adjacent segments L1, L3, and L5 will not have problems? I sincerely request that you share your insights and assistance without reservation, so I can prepare for my exam! I am very grateful...

Dear Ms.
Chuang,
Hello! Due to a herniated disc (L2-L4) compressing the nerves, I underwent surgery.
The doctor advised against pregnancy.
It has been over two years since the surgery, and although I have been diligently undergoing rehabilitation, my body still feels weak, and I experience leg soreness and a sense of weakness.
There is a possibility of further degeneration at lumbar levels L1, L3, and L5, which may require another surgery.

What are the potential postoperative sequelae? Generally, sequelae may include decreased range of motion in the lumbar joints, reduced muscle strength in the back, and persistent soreness, among others.

Is the risk of a second surgery high? It depends on the type of surgery being performed.
The surgeon will discuss the risks of the procedure with the patient prior to the operation.
Regardless, there will always be risks involved, but the surgeon aims to perform the best possible surgery within their skill set.
The second surgery is typically more challenging due to the formation of adhesions in the tissues from the first surgery, which increases the associated risks.
Thank you for your letter, and I welcome you to stay in touch.
Sincerely,
Director Li Wei-Chiang
Department of Rehabilitation Medicine
Taoyuan Hospital

More Info

Understanding spinal fusion surgery is crucial for patients dealing with conditions like herniated discs or spondylolisthesis. Here are some insights and answers to your questions based on the information provided and general medical knowledge.

1. Why is it best not to get pregnant after spinal fusion surgery?
Pregnancy can significantly alter the biomechanics of the spine due to weight gain and hormonal changes that affect ligament laxity. This can place additional stress on the lumbar spine, potentially leading to complications or pain in a patient who has undergone spinal fusion. Furthermore, if complications arise during pregnancy, the treatment options may be limited due to the need to avoid certain medications or procedures that could affect the fetus. Therefore, it is often advised to wait until you are fully recovered and have discussed your plans with your healthcare provider before considering pregnancy.

2. Why do I still feel weak and experience pain in my legs two years post-surgery?
Persistent weakness and pain can be attributed to several factors. After spinal fusion, it is common for patients to experience residual symptoms due to nerve irritation or damage that may have occurred prior to surgery. Additionally, the body may take time to fully adapt to the changes in spinal mechanics after fusion. Muscle weakness can also arise from disuse or atrophy, particularly if you have been less active due to pain. It is essential to engage in a structured rehabilitation program that includes physical therapy to strengthen the surrounding muscles and improve function. If symptoms persist or worsen, it is crucial to consult your physician to rule out any complications or recurrence of the original condition.

3. What types of surgeries are considered spinal fusion surgeries?
Spinal fusion surgery can be performed using various techniques, including traditional open surgery, minimally invasive surgery, and endoscopic surgery. The goal of all these procedures is to stabilize the spine by fusing two or more vertebrae together. In contrast, procedures like microdiscectomy or laminectomy focus on removing herniated disc material or decompressing the spinal canal without necessarily fusing the vertebrae. Therefore, if your surgery involved the fusion of vertebrae, it would be classified as a spinal fusion surgery.

4. Which surgical approach minimizes issues in adjacent segments (L1, L3, L5)?
While no surgical approach can guarantee that adjacent segments will remain problem-free, certain techniques may reduce the risk. For instance, using a minimally invasive approach can help preserve surrounding tissues and maintain the natural biomechanics of the spine. Additionally, ensuring proper alignment and stabilization during the fusion process can help distribute loads more evenly across the spine, potentially reducing stress on adjacent segments. However, it is essential to maintain a healthy lifestyle, including regular exercise and weight management, to support spinal health post-surgery.

In conclusion, spinal fusion surgery is a significant procedure that can lead to improved quality of life for many patients. However, it is essential to have realistic expectations regarding recovery and to engage in ongoing communication with your healthcare team. If you have further concerns or symptoms, do not hesitate to reach out to your physician for personalized advice and management strategies.
