Nonunion Fractures: Treatment Options for Lumbar Injuries

The issue of nonunion fractures?

Hello Dr.
Lee, I was in a car accident a year ago that resulted in a burst fracture of my fifth lumbar vertebra.
During the surgery, the procedure used to stabilize my lumbar vertebrae four and five, as well as the sacrum, was decompression.
However, during my follow-up visit, the doctor informed me that my bones have hardly healed and are still in a similar condition as they were at the time of the accident.
This has made me very anxious.
Could you please advise me on any possible remedies or treatments? Is it necessary to replace the fifth vertebra with an artificial joint? Thank you very much for your help!

Dr. Li Wenlin reply Orthopedics

Hello,
In response to your question, please do not worry too much.
Although the bone has not healed, the internal implants (pedicle screws and internal fixation) are still in place, so stability should not be an issue.
What is more important is your clinical presentation.
If you feel well clinically, are not in pain, and do not have any neurological symptoms such as lower limb weakness, you do not need to be concerned about the bone healing in the short term.
This issue should be addressed by your attending physician, who can evaluate and suggest any remedial measures or treatments.
If you wish to seek a second opinion from another physician, you may need to bring your X-rays and surgical records to their office for further evaluation.
Each case can develop differently based on factors such as age, occupation, fracture type, and treatment methods.
Therefore, your attending physician is most familiar with your situation, so please communicate with them frequently.
Lastly, I wish you all the best!
Dr.

Dear Patient,
Thank you for reaching out regarding your concerns about your lumbar injury and the nonunion of your fifth lumbar vertebra following your car accident. Nonunion fractures, particularly in the lumbar spine, can be challenging and may require a multifaceted approach to treatment.

Understanding Nonunion Fractures
A nonunion fracture occurs when a broken bone fails to heal properly, resulting in persistent pain and instability. In your case, the fifth lumbar vertebra (L5) has not healed as expected after your initial surgery, which involved decompression and stabilization of the affected vertebrae. This situation can arise due to various factors, including inadequate blood supply to the fracture site, infection, mechanical instability, or insufficient immobilization during the healing process.

Treatment Options
1. Conservative Management: Initially, some patients may benefit from conservative management, which includes physical therapy, pain management with medications, and possibly the use of a brace to stabilize the spine. However, given your situation where the bone has not healed for a year, this approach may not be sufficient.

2. Surgical Intervention: If conservative measures fail, surgical options may be necessary. Here are some potential surgical interventions:
- Revision Surgery: This may involve re-stabilizing the fracture site with additional hardware or bone grafting. Surgeons often use autografts (bone taken from your body) or allografts (donor bone) to promote healing. The goal is to provide a scaffold for new bone growth and to stabilize the area.

- Spinal Fusion: In cases of nonunion, a spinal fusion may be recommended. This procedure involves fusing the affected vertebrae together to eliminate movement at the fracture site, which can help alleviate pain and promote healing. The use of bone grafts is common in this procedure.

- Artificial Disc Replacement: While this is more common for degenerative disc disease, in certain cases where the vertebra is severely damaged, an artificial disc may be considered. However, this is typically reserved for specific indications and may not be the first-line treatment for a nonunion fracture.

3. Bone Stimulators: In some cases, electrical bone stimulators may be used to promote healing in nonunion fractures. These devices can enhance the biological processes involved in bone healing.

4. Lifestyle Modifications: Ensuring optimal nutrition, including adequate calcium and vitamin D intake, is crucial for bone health. Smoking cessation and maintaining a healthy weight can also positively impact healing.

Next Steps
Given the complexity of your situation, it is essential to have a thorough discussion with your orthopedic surgeon or a spine specialist. They can evaluate your current condition through imaging studies (like X-rays or MRI) to assess the status of the nonunion and determine the best course of action. It may also be beneficial to seek a second opinion if you feel uncertain about the proposed treatment plan.

Conclusion
In summary, while nonunion fractures can be concerning, there are several treatment options available. Surgical intervention is often necessary for cases that do not heal with conservative management. Your healthcare provider will guide you through the best options tailored to your specific situation. Remember, timely intervention can significantly improve your prognosis and quality of life.
