BackgroundScattered reports exist in the medical literature regarding facet tropism. However, this finding has had mixed conclusions regarding its origin and impact on the normal spine.MethodsWe performed a literature review of the anatomy, embryology, biomechanics, and pathology related to lumbar facet tropism.ResultsFacet tropism is most commonly found at L4-L5 vertebral segments and there is some evidence that this condition may lead to facet degenerative spondylolisthesis, intervertebral disc disease, and other degenerative conditions.ConclusionLong-term analyses of patients are necessary to elucidate relationships between associated findings and facet tropism. In addition, a universally agreed definition that is more precise should be developed for future investigative studies.Copyright © 2017 Elsevier Inc. All rights reserved.
