THE ILIOLUMBAR LIGAMENT: COMPUTER TOMOGRAPHIC MULTIPLANAR REFORMATTING AND THREE-DIMENSIONAL COMPUTER RECONSTRUCTION (technical description)

Purpose: to create technical conditions for spiral X-ray computer tomography of the lumbosacral spine in conjunction with the iliopsoas ligament. Materials and methods. The new protocol of computer tomography was tested on phantoms, followed by approbation in 47 patients (average age - 56,1 ± 8,7) with the pain syndrome in the lower back. Results. We developed a new research protocol that makes it possible to visualize not only the structural elements of the spine, but also to obtain information about the spatial characteristics and morphometric parameters of iliopsoas ligaments. Conclusion. The application of multiplanar reformatting and three-dimensional reconstructions of the data obtained from CT scans by the new research protocol provides the most complete information about the state of iliopsoas ligaments.
