Surgical treatment of spinal deformities associated with neurological deficits using 3D modeling technologies

BACKGROUND: Progressive spinal cord compression in spinal deformities leads to neurological deficit, creating a high risk of patient disability. Modern 3D modeling technologies allow for the production of individual implants and the creation of full-size models of the spine and spinal cord, which radically improves the approach to treating patients with severe spinal deformities. These technologies are especially effective in congenital anomalies, tumors, and post-traumatic defects, providing a better spatial representation of the pathology and the possibility of personalized surgical treatment of neurologically complicated spinal deformities. CLINICAL CASES DESCRIPTION: The results of two patients with kyphoscoliotic deformities of the spine combined with spinal cord compression using custom metal structures and 3D modelling capabilities are presented. Clinical examples show the choice of surgical tactics in the treatment of progressive kyphoscoliotic deformities leading to spinal cord compression. Methods of spinal cord decompression and surgical planning using individual full-size 3D models of the spine and spinal cord are presented, as well as the possibility and effectiveness of using individual plates to fix spinal deformities. CONCLUSION: Surgical treatment resulted in stable fixation of the deformity and regression of the neurological deficit, helping to prevent disability and restore functional activity.
