Our Summary
This research paper is a study comparing two types of back surgeries: midline lumbar fusion (MIDLF) and posterior lumbar interbody fusion (PLIF). The research involved evaluating patients who had one of these surgeries and following up with them for at least a year.
The researchers found that MIDLF had several advantages over PLIF. Patients who had the MIDLF surgery lost less blood, had lower levels of a muscle damage marker post-surgery (creatine kinase), recovered faster, and had a shorter hospital stay. They also reported lower levels of back pain after surgery.
In the three months after surgery, the MIDLF group also showed more improvement in a measure of disability related to back pain (the Oswestry Disability Index) than the PLIF group.
The study also found that the fusion rate (the successful joining of the vertebrae) was slightly higher in the MIDLF group, but this result wasn’t statistically significant, meaning it could have happened by chance.
The rate of complications such as loose screws or cage subsidence (sinking of the implanted device) was similar in both groups. However, there were two cases of complications and both were in the PLIF group.
The researchers concluded that MIDLF is a safe and effective surgery for lumbosacral fusion (joining the lower back and sacral spine), and is in line with the concept of enhanced recovery after surgery.

Doctor’s Tip
One helpful tip a doctor might tell a patient about lumbar fusion is to follow post-operative instructions carefully, including proper lifting techniques, avoiding excessive bending or twisting of the spine, and attending physical therapy sessions to help with recovery and strengthening of the back muscles. It is also important to maintain a healthy weight and lifestyle to support the healing process and reduce the risk of complications. Regular follow-up appointments with your healthcare provider are essential to monitor progress and address any concerns.
Suitable For
Overall, lumbar fusion surgery is typically recommended for patients who have severe back pain and dysfunction that has not improved with conservative treatments such as physical therapy, medication, and injections. Patients with conditions such as degenerative disc disease, spondylolisthesis, spinal stenosis, or spinal instability may be candidates for lumbar fusion surgery.
However, it is important for patients to undergo a thorough evaluation by a spine specialist to determine if they are good candidates for lumbar fusion surgery. Factors such as the location and severity of the spinal condition, overall health and medical history, and the likelihood of success with surgery should be taken into consideration when deciding on the best treatment approach for each individual patient.
Timeline
Overall, the timeline of a patient’s experience before and after lumbar fusion surgery would typically involve a period of preparation, surgery, recovery, and follow-up appointments.
Before surgery, the patient would undergo imaging tests such as X-rays or MRI scans to determine the extent of the spinal issues and to plan the surgical approach. They may also have pre-operative appointments with their surgeon, anesthesiologist, and physical therapist to discuss the procedure and post-operative care.
During the surgery, the patient would be under general anesthesia and the surgeon would access the spine through an incision in the lower back. The damaged disc or vertebrae would be removed and replaced with bone graft material to promote fusion. Hardware such as screws or rods may also be used to stabilize the spine during healing.
After surgery, the patient would typically stay in the hospital for a few days for monitoring and pain management. Physical therapy would begin soon after to help the patient regain strength and flexibility in the spine. The patient would gradually increase their activity level and follow up with their surgeon for post-operative appointments.
In the months following surgery, the patient would continue to work on strengthening their back muscles and improving their range of motion. They may experience some discomfort or stiffness during this time but should gradually see improvements in their pain levels and overall function.
Overall, the goal of lumbar fusion surgery is to alleviate pain, improve spinal stability, and restore function for the patient. With proper care and rehabilitation, most patients can expect to see positive outcomes and improved quality of life following lumbar fusion surgery.
What to Ask Your Doctor
Some questions a patient should ask their doctor about lumbar fusion include:
- What are the specific differences between MIDLF and PLIF surgeries?
- What are the potential risks and complications associated with each type of surgery?
- How long is the recovery process for each surgery, and what can I expect in terms of pain management and physical therapy?
- How likely is it that the surgery will successfully fuse the vertebrae and relieve my back pain?
- Are there any specific factors about my medical history or condition that may make one type of surgery more suitable for me than the other?
- What is the expected outcome in terms of pain relief and functional improvement after surgery?
- How many of these surgeries have you performed, and what is your success rate?
- Are there any alternative treatment options to consider before undergoing lumbar fusion surgery?
- What is the long-term prognosis for patients who undergo lumbar fusion surgery?
- How will this surgery impact my daily activities and quality of life in the long term?
