Rare ligamentum flavum cyst causing incapacitating lumbar spinal stenosis: Experience with 3 Chinese patients
Three Chinese patients suffered from severe lumbar spinal stenosis with debilitating symptoms due to a rare condition of ligamentum flavum cysts in the midline of the lumbar spine. This disease is distinct from synovial cyst of the facet joints or ganglion cysts, both intraoperatively and histopathologically. Magnetic Resonance imaging features of the ligamentum flavum cyst are also demonstrate...
متن کاملHypertrophy of ligamentum flavum in lumbar spinal stenosis associated with increased proteinase inhibitor concentration.
BACKGROUND It is well known that age-related fibrosis, or decreases in the elastin-to-collagen ratio of the ligamentum flavum, along with hypertrophy of the ligamentum flavum, are associated with lumbar spinal stenosis. However, the molecular mechanism by which this fibrosis and hypertrophy develop is unknown. Tissue inhibitors of matrix metalloproteinase (TIMPs) are proteinase inhibitors that ...
متن کاملThe Role of the Ligamentum Flavum Area as a Morphological Parameter of Lumbar Central Spinal Stenosis.
BACKGROUND Hypertrophy of the ligamentum flavum (LF) has been considered as a major cause of lumbar central spinal stenosis (LCSS). Previous studies have found that ligamentum flavum thickness (LFT) is correlated with aging, disc degeneration, and lumbar spinal stenosis. However, hypertrophy is different from thickness. Thus, to evaluate hypertrophy of the whole LF, we devised a new morphologic...
متن کاملCongenital lumbar spinal stenosis with ossification of the ligamentum flavum in achondroplasia: a case report
INTRODUCTION Achondroplasia is a genetic disorder of bone growth. Congenital spinal stenosis is a well-known complication of this disease, but, to the best of our knowledge, no cases involving combined stenosis with congenital lumbar spinal stenosis and ossification of the ligamentum flavum in achondroplasia have been reported previously. In this report, we describe a case of a patient with con...
متن کاملMicroRNA-221 Regulates Hypertrophy of Ligamentum Flavum in Lumbar Spinal Stenosis by Targeting TIMP-2.
STUDY DESIGN A study of lumbar ligamentum flavum (LF). OBJECTIVE The aim of this study was to identify LF hypertrophy related microRNAs (miRNAs) expression profile and to investigate the role of miRNAs in the development of LF hypertrophy in lumbar spinal stenosis (LSS). SUMMARY OF BACKGROUND DATA Although histologic and biologic literature on LF hypertrophy is available, the pathomechanism...
