Thickened ligamenta flava obtained from 14 patients with spinal canal stenosis were examined with special reference to type VI collagen. The characteristic histological finding in the thickened area was rupture of normal elastic fibre meshwork with resultant fibrosis which usually appeared hyaline. Using an immunohistological method, collagen types VI, I and III were found to be present in the hyaline matrix. Ultrastructural study revealed many microfilamentous structures of type VI collagen… 

Collagen profiling of ligamentum flavum in patients with lumbar spinal canal stenosis.

Ligamentum flavum fibrosis and hypertrophy: Molecular pathways, cellular mechanisms, and future directions

The current status of detailed knowledge available regarding the causative factors, pathology, molecular and cellular mechanisms implicated in LF fibrosis and hypertrophy are summarized, also focusing on the possible avenues for anti‐fibrotic strategies.

The Pathology of Ligamentum Flavum in Degenerative Lumbar Disease

Various pathologic findings provided important foundations for discussing the pathogenesis of lesions in ligamentum flavum, and calcification was frequently observed in elderly patients and those with cauda equina symptoms, and these patients tended to have severer preoperative symptoms.

Comparison of Histological Changes in the Ligamentum Flavum from Spinal Canal Stenosis Patients with and without Diabetes Mellitus

It is shown that diabetes mellitus has no effect on histological change in ligamentum flavum of spinal canal stenosis and mechanical stress (due to overweight) has a more important role in pathogenesis of spinal Canal stenosis.

Evaluation of the rostral projection of the sacral lamina as a component of degenerative lumbosacral stenosis in German shepherd dogs

Rostral projection of the sacral lamina, previously proposed as a potential risk factor in dogs with CES due to lumbosacral degeneration, was not associated with a diagnosis of DLSS in this study; the opposite was true.

Anatomie der Lumbalstenose

Die lumbale Spinalstenose ist erst in den letzten Jahrzehnten zu einem greifbaren Krankheitsbild geworden. Sie ist dadurch definiert, dass ein Missverhaltnis zwischen dem Raumbedarf fur das



Ultrastructure of type VI collagen in human skin and cartilage suggests an anchoring function for this filamentous network

It is suggested that the type VI collagen forms a flexible network that anchors large interstitial structures such as nerves, blood vessels, and collagen fibers into surrounding connective tissues.

Immunohistochemical studies on the tissue localization of collagen types I, III, IV, V and VI in schwannomas

Findings indicate that the differently organized cellular patterns of schwannomas, identified as Antoni types A and B, are characterized not only by the ultrastructural features of the extracellular matrix, but also by the distinctive collagen types produced by neoplastic Schwann cells.

Left ventriculotomy of the heart: tissue repair and localization of collagen types I, II, III, IV, V, VI and fibronectin

Results indicate that the ventriculotomy was finally repaired in the form of a fibrous scar, particularly in the endocardium.

Collagen type I and type V are present in the same fibril in the avian corneal stroma

The results indicate that collagen types I and V are assembled together within single fibrils in the corneal stroma such that the interaction of these collagen types within heterotypic fibril masks the epitopes on the type V collagen molecule.

Immunochemistry, genuine size and tissue localization of collagen VI.

Ulastructural studies using the immunoferritin technique showed collagen VI along thin filaments or in amorphous regions of aortic media or placenta but not in association with thick, cross-striated collagen fibrils or elastin, supporting previous suggestions that collagen VI is a constituent of microfibrillar structures of the body.

Immunohistochemical study of arteriolar (simple) hyalinosis in spleen.

The morphogenesis and exact chemical composition of hyaline masses have not been satisfactorily explained and two different theories concerning morphogenesis of the lesion have been advanced.


The findings indicate that arteriolar hyalin may constitute a deposit of substances of hematogenous origin and that it is distinct from collagen, elastic tissue, basement membrane material, fibrin and amyloid.
