Inspired Spine's OLLIF safer for obese patients than MIS-TLIF — 4 insights


A new study compared surgical outcomes of Inspired Spine's oblique lateral lumbar interbody fusion to transforaminal lumbar interbody fusion in patients with body mass index of 30 or greater.

The study involved a retrospective evaluation of 321 patients at one Minnesota hospital. Patients either received TLIF, MIS-TLIF or OLLIF to treat degenerative disc disease, spondylolisthesis, spondylosis, herniation, stenosis or scoliosis.

Here are four insights:

1. Researchers found significantly decreased blood loss in the OLLIF group compared to the TLIF cohort.

2. The surgery time rose significantly as BMI increased for patients receiving TLIF or MIS-TLIF.

3. The study revealed a BMI one-point increase yielded longer surgery time and increased blood loss in the TLIF group.

4. Researchers found OLLIF to be the safest surgery at any BMI compared to TLIF or MIS-TLIF.
