High Sacral Endplate Inclination Vector Forces Are Associated with Pars Fracture-Mediated Lumbosacral Spondylolisthesis.

World Neurosurg 2019 Feb 1;122:e790-e794. Epub 2018 Nov 1.

Department of Neurosurgery, Harvard Medical School, Boston, Massachusetts, USA. Electronic address:

Objective: Lumbar spondylolisthesis can be related to facet arthropathy and disc degeneration or to a fracture of the pars interarticularis, but the mechanistic underpinnings of spondylolisthesis remain unclear. We posit that high sacral slope and body weight increase sacral inclination vector forces, which leads to pars fractures and exacerbates risk for spondylolisthesis.

Methods: To investigate this hypothesis, we measured the sacral slope, body weight, and S1 endplate vector forces for patients who underwent L5-S1 fusion for grade I spondylolisthesis. Read More

A Retrospective Review of Spinal Radiofrequency Neurotomy Procedures in Patients with Metallic Posterior Spinal Instrumentation - Is it Safe?

Pain Physician 2018 09;21(5):E477-E482

Rutgers New Jersey Medical School Department of Pain Management, Newark, NJ.

Background: Recent studies have shown that medial branch radiofrequency neurotomy (RFN) procedures done at the level of a pedicle screw can increase pedicle screw temperature, and it has been speculated that pedicle screw heating may cause thermal injury. There has been a limited amount of investigation into the real-world safety profile of RFN procedures in patients with pedicle screws.

Objectives: We aim to demonstrate that the occurrence of serious adverse events is rare for a medial branch RFN procedure completed at a level with metallic spinal hardware when performed according to the Spine Intervention Society practice standards. Read More

Biportal Endoscopic Spine Surgery for Various Foraminal Lesions at the Lumbosacral Lesion.

Asian Spine J 2018 Jun 4;12(3):569-573. Epub 2018 Jun 4.

Spine Center, Barun Hospital, Jinju, Korea.

The stenosing foramen of L5-S1 by several degenerative diseases is one of the challenging areas on surgical approaching because of the deeper depth and steep slope in the lumbosacral junction. The floating view using unilateral biportal endoscopic spine surgery rather than docking into the Kambin's zone can make the foraminal structures seen panoramically and permit dynamic handling of various instruments without destroying the facet joint and causing iatrogenic instability. Fine discrimination of structural margins in helps of the higher magnification and gentle manipulation of neural structures just as in open spine surgery could be guaranteed using floating technique from the target structures.
