Post-Surgery Complications: Challenges in Walking and Sitting After L5-S1 Support Frame Surgery - Neurosurgery

Share to:

After the insertion of a support frame at L5 and S1, the patient is unable to sit or walk?


Hello, doctor.
My mother underwent a spinal fusion surgery between L3 and L5 two years ago.
After the surgery, she still felt numbness and soreness in her left leg while walking, and she was unable to walk for more than 20 minutes.
In early March of this year, she had another spinal fusion surgery between L5 and S1.
Within two weeks post-surgery, she only experienced some weakness in her lower back.
However, in the third week, coinciding with a drop in temperature, she began to complain that her legs felt extremely cold and numb, to the point where she felt weak and unable to walk.
By the fourth week, she started experiencing pain even while sitting, with two specific points in her buttocks being very painful, and her legs remained numb all the way to her feet.
When she needs to switch legs while walking, she lacks the strength to do so.
An electromyography (EMG) test showed signs of nerve damage at L5 and S1.
I would like to ask the doctor if the nerve damage at L5 and S1 could have been present before the surgery, and if the spinal fusion surgery could have exacerbated the nerve symptoms, leading to her inability to sit or walk.
Is it possible to resolve this condition? I would greatly appreciate your insights.

Post-surgery complications, particularly after spinal surgeries such as the L5-S1 support frame surgery, can be quite challenging and distressing for patients and their families. Your mother's situation, characterized by persistent pain, numbness, and weakness in her legs, raises several important considerations regarding her recovery and the potential for further treatment.

Firstly, it is crucial to understand that spinal surgeries, especially those involving the lumbar region, can sometimes lead to complications such as nerve damage, which may have been pre-existing or exacerbated by the surgical procedure. In your mother's case, the electromyography (EMG) results indicating nerve damage at the L5 and S1 levels suggest that there may have been some degree of nerve impairment prior to the surgery. However, surgical intervention can sometimes lead to further irritation or compression of the nerves, especially if there is swelling or scar tissue formation post-operatively.

The symptoms your mother is experiencing—coldness, numbness, and weakness in her legs—are indicative of nerve involvement. The fact that she is unable to walk for extended periods and experiences pain while sitting suggests that her condition may not be improving as expected. It is not uncommon for patients to experience heightened sensitivity or exacerbation of symptoms following surgery, particularly if there was pre-existing nerve damage. This can occur due to inflammation, changes in the spinal alignment, or the formation of scar tissue that may further compress the nerves.

Regarding the question of whether her condition can be resolved, it is essential to have a thorough evaluation by her neurosurgeon or a specialist in spinal disorders. They may recommend additional imaging studies, such as an MRI, to assess the current state of her spine and the surrounding structures. This can help determine if there are any new developments, such as herniated discs or other issues that may require further surgical intervention.

In some cases, conservative management may be appropriate, including physical therapy, pain management strategies, and possibly medications to address nerve pain. Physical therapy can be particularly beneficial in helping to strengthen the muscles around the spine, improve mobility, and alleviate some of the discomfort associated with nerve irritation. However, if conservative measures do not yield significant improvement, a surgical consultation may be warranted to discuss the possibility of additional procedures to relieve nerve compression.

It is also important to consider the psychological aspects of recovery. Chronic pain and mobility issues can lead to frustration, anxiety, and depression. Support from family, friends, and mental health professionals can be invaluable during this challenging time.

In summary, while your mother's symptoms are concerning, there may still be options for treatment and improvement. A comprehensive evaluation by her healthcare team will be essential in determining the best course of action moving forward. Open communication with her medical providers about her symptoms, concerns, and treatment goals will be crucial in navigating her recovery journey.
