Minimally Invasive Direct Lateral Interbody Fusion (MIS-DLIF): Proof of Concept and Perioperative Results

Background: Minimally invasive direct lateral interbody fusion (MIS-DLIF) is a novel approach for fusions of the lumbar spine. In this proof of concept study, we describe the surgical technique and report our experience and the perioperative outcomes of the first nine patients who underwent this procedure.

Minimally Invasive Direct Thoracic Interbody Fusion (MIS-DTIF): Technical Notes of a Single Surgeon Study

Background: Minimally invasive direct thoracic interbody fusion (MIS-DTIF) is a new single surgeon procedure for fusion of the thoracic vertebrae below the scapula (T6/7) to the thoracolumbar junction. In this proof of concept study, we describe the surgical technique for MIS-DTIF and report our experience and the perioperative outcomes of the first four patients who underwent this procedure.

Oblique Lateral Lumbar Interbody Fusion (OLLIF): Technical Notes and Early Results of a Single Surgeon Comparative Study

Alexandria, MN-October 15, 2015- Dr. H. R. Abbasi, a pioneer in advanced minimally invasive surgical services, is committed to providing the most innovative neurological spinal surgery options to Minnesota. He is board-certified with the American Board of Neurological Surgery and trained for over 23 years at some of the world’s most prestigious medical institutions, including Stanford University, Dartmouth College and the University of Texas, MD Anderson.

Dr. Abbasi is proud to announce that his study Oblique Lateral Lumbar Interbody Fusion (OLLIF): Technical Notes and Early Results of a Single Surgeon Comparative Study has been published by Cereus.com. The peer reviewed study found compared the surgery data between open spinal surgeries, transformational lumbar interbody fusions (TLIF), and OLLIF. We present data from 69 consecutive OLLIF surgeries on 128 levels with a control group of 55 consecutive open transformational lumbar interbody fusions (TLIFs) on 125 levels. For a single level OLLIF, the mean surgery time is 69 minutes (min) and blood loss is 29 ml. Surgery time was approximately twice as fast as open TLIF (mean: 135 min) and blood loss is reduced by over 80% compared to TLIF (mean: 355 ml). We found that OLLIF is a minimally invasive fusion that significantly reduces surgery times compared to open surgery. OLLIF overcomes the difficulties of traditional open fusions, making it a safe and technically less demanding surgery than open or minimally invasive TLIF.

Economic Performance of Oblique Lateral Lumbar Interbody Fusion (OLLIF) with a Focus on Hospital Throughput Efficiency

Abstract

Oblique lateral lumbar interbody fusion (OLLIF) is a minimally invasive lumbar surgery. Differences in resource consumption between open spinal surgeries, transformational lumbar interbody fusions (TLIF) and OLLIF, are not documented. We monetize quantifiable differences in resource utilization between the two procedures.

Lower back pain is one of the most prevalent and expensive health care conditions in the western world. The standard treatment, interbody fusion, in an invasive procedure that requires stripping the muscles and soft tissue. This leads to blood loss and a long recovery time.

The Oblique Posterior Lateral Lumbar Fusion (OLLIF) is a surgical procedure designed for a minimally invasive spinal fusion. The OLLIF allows for fusion of the lumbar spine through a single 10-15mm incision, with faster surgery times and easier approach than any previous technique. This procedure is normally performed for patients that require a spinal fusion, but do not want the recovery time required in a traditional spinal fusion surgery.

There are also cost reductions associated with the OLLIF procedure. Based on a comparison of the results from 154 OLLIF patient results and 56 TLIF patient results there are significate cost reduction with the OLLIF. The minimally invasive approach of the OLLIF results in significantly less blood loss than the TLIF. It also results in less surgery time which greatly reduce costs. Depending on the level of the procedure, the surgery time cost reduction can exceed $8,500.00. The patient spends less inpatient days creating a potential cost reduction of more than $5,500.00 depending on the number of levels. The OLLIF can result in cost reductions in excess of $14,000.00.

The cost reductions and faster recovery times associated with the OLLIF procedure make it an appealing alternative to the traditional open fusions available for the patient and insurance providers. This is evident in the included study results and cost analysis completed based on those results.

One of my passions is having the opportunity to share the OLLIF with my peers. I want to help bring this innovative technique to the attention of my fellow neurosurgeons so they can witness the benefits of this procedure on their own patients. As part of this goal I will be adding information periodically to my website. I encourage any physician who is interested in learning more to contact me. I look forward to discussing the OLLIF with you.

Sincerely,
Hamid R. Abbasi MD PhD, FAANS
