Research and Perspectives in Lumbar Interbody Fusion—Q2 2015

Perspectives and data analysis on the outcomes and efficacy of a variety of Lumbar Interbody Fusion techniques have been popular on Google in the second quarter.

Below are some of the most-read surgery and research stories on the web in Lumbar Interbody Fusion for late spring and early summer of 2015: .

Lateral Lumbar Interbody Fusion—how are patients doing 2 years after the procedure?

A study in the Journal of Spinal Disorders & Techniques published in May 2015 examines outcomes for patients who had a minimally-invasive Lateral Lumbar Interbody Fusion (LLIF) two years prior.

118 study participants followed two years after LLIF had significantly improved scores for:

  • Their Visual Analog Scale for Pain
  • Oswestry Disability Index
  • Physical components summary

The study also found an 88% successful fusion rate. The most frequent complication was transient thigh pain, found in 36% of patients.

Overall, researchers say this data supports the “efficacy of minimally invasive LLIF in improvements of clinical and radiographic features”. At this juncture, that’s great news for patients’ peace of mind.

Oblique Lateral Interbody Fusion—3 Surgeons’ perspectives

After more than 10 years of successful lateral spine surgeries, Oblique Lateral Interbody Fusion (aka OLIF at L2-L5) allows surgeons lateral access while preserving the psoas and simultaneously avoiding the iliac crest.

Three spine surgeons, who were interviewed on their opinions about OLIF at L2-L5, all see crystal-clear advantages to the surgery, including a first in spine surgery history: with this method, surgeons can reach every disc level from L5-S1 through the thoracic spine without ever changing the position of the patient.

While the procedure takes a “mental shift” to the oblique position, avoiding crucial nerve areas and the lumbosacral plexus is a definite plus.

Other benefits of OLIF at L2-L5 perceived by surgeons include:

  • Better position for the surgeon to perform surgery
  • Don’t have to move the fluoroscopy
  • Happier patients (recovery can be easier)

Outcomes comparable in XLIF, MIS TLIF

It’s still early to compare Extreme Lateral Interbody Fusion (XLIF) with minimally-invasive Transforaminal Lumbar Interbody Fusion (MIS TLIF) for the treatment of low-grade degenerative spondylolisthesis. Additional, continuing studies to determine which method results in better outcomes for patients are in order.

A multicenter comparative study led by Jonathan N. Sembrano, MD, analyzed the results of 48 patients with spondylolisthesis who underwent either XLIF or MIS TLIF. Results were comparable for both procedures in the following areas:

  • Patient-Reported Pain
  • Function
  • Satisfaction
  • Significant Improvement over Baseline
  • Low Complication Rates
  • Postoperative Reduction of Spondylolisthesis
