Anterior lumbar compared to oblique lumbar interbody approaches for multilevel fusions to the sacrum in adults with spinal deformity and degeneration.

J Neurosurg Spine 2020 Jun 12:1-10. Epub 2020 Jun 12.

3Department of Orthopedic Surgery, University of California, San Francisco, California; and.

Objective: In adult spinal deformity and degenerative conditions of the spine, interbody fusion to the sacrum often is performed to enhance arthrodesis, induce lordosis, and alleviate stenosis. Anterior lumbar interbody fusion (ALIF) has traditionally been performed, but minimally invasive oblique lumbar interbody fusion (OLIF) may or may not cause less morbidity because less retraction of the abdominal viscera is required. The authors evaluated whether there was a difference between the results of ALIF and OLIF in multilevel anterior or lateral interbody fusion to the sacrum. Read More

Inter-observer Variance and Patient Heterogeneity Influencing The Treatment of Grade I Spondylolisthesis.

Spine J 2020 Jun 10. Epub 2020 Jun 10.

Department of Neurosurgery, Lahey Clinic, Boston, Massachusetts.

Background Context: Despite well done randomized clinical trials, the role of fusion as an adjunct to decompression for the treatment of patients with degenerative spondylolisthesis remains controversial. There is substantial variation in the use of fusion as well as the techniques used for fusion for a population of patients all described by a single ICD10 code.

Purpose: We sought to investigate the source of the variation in the perceived role of fusion by looking at surgeon as well as patient specific factors. Read More

Tackling Research Inefficiency in Degenerative Cervical Myelopathy: Illustrative Review.

JMIR Res Protoc 2020 Jun 11;9(6):e15922. Epub 2020 Jun 11.

Division of Neurosurgery, Department of Clinical Neurosciences, University of Cambridge, Cambridge, United Kingdom.

Background: Degenerative cervical myelopathy (DCM) is widely accepted as the most common cause of adult myelopathy worldwide. Despite this, there is no specific term or diagnostic criteria in the International Classification of Diseases 11th Revision and no Medical Subject Headings (MeSH) or an equivalent in common literature databases. This makes searching the literature and thus conducting systematic reviews or meta-analyses imprecise and inefficient. Read More
