Wiersbicki D, et al. - Via Giemsa- and PAS-stained plastinated body slices of 15 lumbar spines, the researchers assessed intraforaminal ligaments (IFL) in lumbar neural foramina (NF) and their relation to the lumbar spinal nerves (SN). One fixed lumbar spine was dissected and studied. However, for a detailed study of the IFL, manual dissection appeared to be inappropriate. Being free of the SN, the lateral and intermedial compartments could transmit power and protect the SN, while the thin medial IFL could lead the SN passing the NF under physiological conditions. Hence, from the close topographical relation, it was concluded that the IFL could be relevant in foraminal stenosis. Furthermore, any herniation in the NF pressed IFL to the SN suggesting that in case of their non-physiological turnover IFL themselves could cause neurogenic claudication. Also, using MRI visualization of IFL could be possible.
