Our Summary
This study looked at how the position of a surgical implant, called a cage, can affect the results of a type of back surgery called a transforaminal lumbar interbody fusion (TLIF). The researchers analyzed 130 patients who had this surgery, taking X-rays before and after surgery, and then again at their last follow-up appointment.
The cage’s position was categorized based on three groups: front, middle, and back. The researchers looked at different measurements, like the curve of the lower back and the heights of different parts of the spinal disc, to see how they changed after the surgery.
They found that all groups saw increases in certain measurements after the surgery. However, the group with the cage at the front saw the biggest increase in the curve of the lower back, followed by the middle group. The back group saw little change in this measurement.
The study also found that the cage’s position and how tall it was could affect the results. For example, a taller cage at the front could lead to a larger curve in the lower back and prevent decreases in certain other measurements.
In summary, the position and size of the cage in this type of back surgery can significantly impact the results seen in X-rays after the surgery.

Doctor’s Tip
A doctor might tell a patient undergoing lumbar fusion surgery to discuss with their surgeon the placement and size of the cage to ensure the best possible outcome. They may also recommend following post-operative instructions carefully to optimize healing and recovery. Additionally, maintaining a healthy lifestyle, including regular exercise and proper nutrition, can help support the healing process and long-term success of the surgery.
Suitable For
Patients who are typically recommended for lumbar fusion surgery are those who have tried other non-surgical treatments for their back pain, such as physical therapy and medication, without success. They may have conditions such as degenerative disc disease, spondylolisthesis, spinal stenosis, or a herniated disc that is causing significant pain and disability. Lumbar fusion surgery may be recommended for patients who have persistent back pain, leg pain, weakness, or numbness that is not improving with conservative treatments.
Additionally, patients who have instability in the spine, such as from a previous injury or from a degenerative condition, may benefit from lumbar fusion surgery to help stabilize the spine and reduce pain. Patients with spinal deformities, such as scoliosis, may also be recommended for lumbar fusion surgery to correct the alignment of the spine and reduce pain.
Overall, lumbar fusion surgery is typically recommended for patients who have significant back pain and related symptoms that are impacting their quality of life and have not responded to conservative treatments. It is important for patients to discuss the risks and benefits of lumbar fusion surgery with their healthcare provider to determine if it is the right treatment option for their specific condition.
Timeline
Timeline of a patient’s experience before and after lumbar fusion surgery:
Before surgery:
- Patient experiences chronic lower back pain and/or leg pain due to conditions such as degenerative disc disease, spinal stenosis, or spondylolisthesis.
- Patient undergoes diagnostic tests such as X-rays, MRI, and CT scans to determine the cause of their pain.
- Patient may try conservative treatments such as physical therapy, medications, and injections to manage their symptoms with limited success.
- Patient consults with a spine surgeon to discuss the option of lumbar fusion surgery as a last resort.
During surgery:
- Patient undergoes pre-operative preparation and anesthesia.
- Surgeon makes an incision in the lower back and accesses the affected area of the spine.
- Surgeon removes damaged disc or bone and inserts a cage or bone graft to stabilize the spine.
- Surgeon may also use screws and rods to further support the fusion.
After surgery:
- Patient stays in the hospital for a few days for monitoring and pain management.
- Patient begins physical therapy to regain strength and mobility.
- Patient follows post-operative instructions for wound care, activity restrictions, and pain management.
- Patient attends follow-up appointments with the surgeon to monitor progress and X-rays are taken to assess fusion success.
- Patient gradually resumes normal activities and may experience improvements in pain and function over several months.
- Patient continues to follow up with the surgeon to monitor long-term outcomes and address any complications that may arise.
Overall, lumbar fusion surgery is a complex procedure that requires careful planning and post-operative care to achieve successful outcomes for patients with debilitating back pain.
