“…43 The scalpel sign is a common descriptor of the anterior displacement of the spinal cord (FIGURE [3][4][5]. 44 CT myelography and MRI of the spine are the most commonly used modalities for diagnosis. [41][42][43] Although some centers consider CT myelography the most helpful imaging modality, no single imaging modality has emerged as universally preferred based on clinical studies.…”

Objective This article illustrates the clinical importance, diagnosis, and management of degenerative and nondegenerative structural myelopathies. It also aims to create a diagnostic approach for the evaluation of patients with suspected degenerative myelopathies. Latest Developments There is considerable interest in developing diagnostic methods that can assist in deciding if surgery is indicated in patients with structural myelopathy and the optimal timing for surgery. Diffusion tensor imaging has emerged as a promising imaging modality although it is not used routinely in clinical practice. Neuroprotective medications and interventions are being studied in patients with degenerative myelopathies. Essential Points Structural myelopathies and particularly degenerative myelopathies are common disorders that are routinely encountered in clinical practice, with symptoms that frequently overlap with other neurologic disorders. The prompt diagnosis and treatment of patients are essential in achieving good functional outcomes.
