Fessler received support of non—study-related clinical or research effort from Medtronic. Retroperitoneal oblique corridor to the L2-S1 intervertebral discs in the lateral position: an anatomic study. In 1 case, the segmental artery was lacerated, which was successfully repaired with bipolar electrocautery. Mini-open approach for direct lateral lumbar interbody fusion. A recent report evaluated other peripheral nervous structures at risk during the lateral approach to the lumbar spine. Simultaneous combined anterior and posterior fusion: an independent analysis of a treatment for the disabled low-back pain patient. During the early postoperative period there were two superficial 0. Mini-open anterior retroperitoneal lumbar interbody fusion: oblique lateral interbody fusion for lumbar spinal degeneration disease. It emerges at the L3—4 level on the anterior surface of the psoas muscle and travels inferiorly covered by the peritoneum to divide into the genital and femoral branches. If patients reported yes to any of the questions they were monitored for longer time periods.

The anterolateral surgical approaches to the lumbar spine are illustrated in Figure 1. Higher lumbar vertebra up to L2–3 can be reached, but oftentimes their exposure is limited because of.
During the last 20 years several less-invasive anterior approaches to the. retroperitoneal oblique corridor to the L2 to S1 intervertebral discs. Request PDF | The Oblique Anterolateral Approach to the Lumbar Spine Provides However, the trans-psoas approach only allows access from L1-L2 to L4-L5.
This approach differs from the previous retroperitoneal approaches in that the access to the spine is directly through the iliopsoas muscle via a much shorter incision, versus a larger exposure and subsequent retraction of the psoas in the posterior direction.
Ozgur et al. A 2-incision technique was described for the approach, with an anchorless 3-blade retractor, and early clinical results were discussed. Extreme lateral approach to the spine in degenerative and post traumatic lumbar diseases: selection process, results and complications.
In the mids, there were several reports of ALIFs that used a laparoscopic approach. Methods A nonrandomized, prospective study utilizing a self-reported patient questionnaire was conducted between January and June at Northwestern University.

extra-axial material posterior to TL2, consistent with blood products (red arrows). An anterior approach is favored when a herniated disc or bone fragment compresses the spinal cord.
During the last 20 years several less-invasive anterior approaches to the lumbar spine have become standard, including the extreme lateral.
Perhaps the greatest impact on postoperative psoas-related morbidity involves the extent of psoas muscle dilation.
We acknowledge this to be a possibility; however, we would expect other neurological findings referable to the L-1 or L-2 nerve roots. The retroperitoneal approach to the lumbar spine was first reported by Harmon 10 in Each author certifies that his or her institution has approved the human protocol for this investigation, that all investigations were conducted in conformity with ethical principles of research, and that informed consent for participation in the study was obtained.

Interestingly, despite neuromonitoring, the reported risk of neurologic deficits with the extreme lateral transpsoas approach is greater than observed with other anterior approaches. Hip flexion weakness is likely due to splitting the psoas muscle.

In the mids, there were several reports of ALIFs that used a laparoscopic approach. They identified 4 other nerves at risk: the subcostal, iliohypogastric, ilioinguinal, and lateral femoral cutaneous nerves.

frequently affected by LSS[a], followed by L3-L4[a], L5-S1 and L1-L2.
A subset analysis of the single-level operations was performed. This was the first report of a transpsoas approach to the spine.
Additionally, electromyography testing confirms the absence or presence of such structures. An alternative lateral, oblique, psoas-sparing approach, recently named the oblique lumbar interbody fusion, uses the anatomic pathway between the abdominal vessels anteriorly and the lumbar plexus laterally to decrease the risk of neurologic and vascular injury; however, as yet, little on this new approach has been reported.
Complication avoidance is of paramount import, and there are several key steps that minimize morbidity. Reports of retrograde ejaculation, 47 vascular injury, 2 anesthetic complications, 9 need for an access surgeon, and steep learning curve all limited the popularity of this procedure.
