In imaging, ankylosing spondylitis initially manifests itself by the association of a lysis of the anterior part of the vertebral corners surrounded by a peripheral reactive sclerosis realizing the aspect of “shiny corner sign,” thereafter there will be the formation of lateral and anterior syndesmophytes connecting the vertebral bodies, all of these signs give the appearance of continuous wavy edges of the vertebrae, , hence the name “bamboo column” or “bamboo spine” ( Figure 1, Figure 2 and Figure 3).Įchchikhi Meryem - Conception of the work, Design of the work, Acquisition of data, Analysis of data, Drafting the work, Revising the work critically for important intellectual content, Final approval of the version to be published, Agree to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.Įl Bakkari Asaad - Conception of the work, Design of the work, Acquisition of data, Analysis of data, Drafting the work, Revising the work critically for important intellectual content, Final approval of the version to be published, Agree to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.īen El Hosni Khadija - Conception of the work, Design of the work, Acquisition of data, Analysis of data, Drafting the work, Revising the work critically for important intellectual content, Final approval of the version to be published, Agree to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved. Spinal ankylosis was initially described by Pierre Marie and Ernst Adolf Gustav Gottfried von Strumpell under the term “rigid as a stick” which was later simplified into “bamboo column.” It represents a major sign of ankylosing spondylarthritis (or Marie–Strumpell’s disease) objectified in the advanced stages of the disease,. This sign can be objectified on conventional radiography as on the scanner and is frequently accompanied by a fusion of the posterior vertebral elements.Īnkylosis in a bamboo column results from the staged ossification of the external fibers of the annulus fibrosus of the intervertebral discs, this conduct to marginal syndesmophytes are formed connecting the vertebral bodies, these preferentially touch the thoracolumbar stage and/or the lumbosacral junction, and expose to unstable fractures and disc damage of Andersson,. The bamboo spine appearance is a radiological sign of spinal ankylosis, which corresponds to the fusion of the vertebral bodies by marginal syndesmophytes. ![]()
