Who is a candidate?
Minimally invasive fusion may be recommended for:
- Spondylolisthesis with leg pain or instability
- Spinal stenosis with instability
- Recurrent disc herniation
- Severe, single- or two-level degenerative disc disease
- Selected degenerative scoliosis and fractures
How the procedure works
A common technique is the minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). Through a small incision on one side of the spine, Dr. Ferachi uses a tubular retractor to reach the disc space, relieves pressure on the nerves, removes the damaged disc and inserts a spacer (cage) packed with bone graft. Screws and rods are then placed through small incisions using percutaneous instrumentation, holding the segment still while the bone fuses.
Potential benefits compared with open surgery
- Smaller incisions and less damage to back muscles
- Less blood loss and lower transfusion risk
- Less post-operative pain and narcotic use
- Shorter hospital stay, often one night
- Earlier walking and return to activity
Recovery
Patients typically walk the day of or the day after surgery. Most return to desk work in about four to six weeks and to heavier activities after three months. Full fusion takes six to twelve months. Physical therapy usually begins several weeks after surgery.
Not every patient or condition is suited to a minimally invasive approach. Dr. Ferachi will recommend the technique that gives you the best chance of a lasting result.
Common questions
Is minimally invasive spine surgery as effective as open surgery?
For appropriate patients, studies show fusion rates and long-term outcomes comparable to open surgery, with advantages in early recovery, blood loss and hospital stay.
How long will I be in the hospital?
Many patients go home after one night. Length of stay depends on the number of levels, your health and how quickly you are walking comfortably.
