What is Direct Lateral Interbody Fusion?

Direct Lateral Interbody Fusion (DLIF) is a minimally invasive spinal surgery used to treat conditions like degenerative disc disease, scoliosis, and spinal instability.

The procedure involves removing a damaged disc and fusing the surrounding vertebrae to restore stability and relieve nerve pressure.

Unlike traditional back surgery, DLIF accesses the spine from the side of your body rather than the back or abdomen. This lateral approach allows surgeons to avoid major muscles and blood vessels, which typically leads to less tissue damage, reduced blood loss, and faster recovery.

Here’s what happens during a DLIF procedure:

• The surgeon makes a small incision on your side, near the waist
• Muscles are gently moved aside, not cut, to reach the spine
• The damaged disc is removed, and a spacer or bone graft is inserted
• The vertebrae are stabilized, often with screws or plates, to promote fusion

DLIF is often preferred for accessing the lower spine, particularly the lumbar region. It’s usually recommended when conservative treatments like physical therapy or medication haven’t worked.

Recovery time varies, but most patients are up and walking within a day or two. Because it’s less invasive, DLIF typically results in a shorter hospital stay and less postoperative pain compared to traditional fusion surgery.

However, not everyone is a candidate. The side approach may not be suitable for patients with certain anatomical structures or previous abdominal surgeries.

If you’re considering spinal fusion, DLIF could be a promising option. Talk to your surgeon about whether it fits your condition and overall health.
