In the literature, hereditary multiple exostosis cases that developed spinal canal stenosis due to spinal osteochondromas have been reported. Lumbar spinal stenosis may occur in a hereditary multiple exostosis patient due to ligamentum flavum hypertrophy, which is a hyperosteotic process that differs from exostosis. We discuss one such case, along with pathogenetic mechanisms and clinical features.enginfo:eu-repo/semantics/closedAccessMultiple Hereditary ExostosesSpinal StenosisLigamentum Flavum Hypertrophyarticle757117130004106182000302-s2.0-849832849471309-2014
