Effect of Approach Based Lumbar Interbody Fusion on Sagittal Spinopelvic Parameters and Functional Outcomes: Comparison between Oblique Lumbar Interbody Fusion (OLIF) and Transforaminal Lumbar Interbody Fusion (TLIF).

Purpose: Transforaminal lumbar interbody fusion (TLIF) and oblique lumbar interbody fusion (OLIF) are the most commonly conducted operations for interbody fusions. In addition to fusion, the restoration of proper spinal alignment has become crucial for achieving favorable functional outcomes. There is a lack of agreement on which lumbar interbody fusion technique provides the most effective correction for sagittal spinopelvic parameters (SSPs).

Does indirect decompression by oblique lateral interbody fusion produce similar clinical and radiological outcomes to direct decompression by open transforaminal lumbar interbody fusion.

Objectives: Open transforaminal lumbar interbody fusion (O-TLIF) remains the most popular and widely practiced lumbar fusion method even today, providing direct decompression. Oblique lateral interbody fusion (OLIF) is a novel retroperitoneal approach that allows placement of a large interbody cage which provides an indirect neural decompression, and screws can be placed minimal invasively or through the Wiltse OLIF (W-OLIF) approach. We aim to find out the short-term efficacy of W-OLIF to O-TLIF in terms of radiological and clinical outcomes in patients of lumbar degenerative diseases.

Gelatin Sponge-induced Early Onset Quadriparesis after the Posterior Decompression for Cervical Myelopathy Due to Ossification of a Posterior Longitudinal Ligament - A Case Report.

Background: Gelatin foam has been regularly used the complex neuro and spinal surgeries for a long time. Apart from their hemostatic properties, these are inert and provide form an inert membrane that prevents scar adhesions o vital structures such as the brain or spinal cord.

Case Presentation: We present a case of cervical myelopathy due to an ossified posterior longitudinal ligament that underwent the instrumented posterior decompression and had neurological worsening 48 h after the index surgery.

Assessment of the psoas muscle changes following the oblique lateral interbody fusion (OLIF) approach: A prospective observational study.

Background: Traditional open posterior fusion techniques involve stripping of the posterior paraspinal muscles with protracted retraction, which can lead to ischemia and denervation. This may result in poor clinical outcomes despite a well-performed surgery. Oblique lumbar interbody fusion (OLIF) is a minimally invasive modified retroperitoneal anterior approach in the corridor between the psoas major (PM) and great vessels.
