Dorsal Column Mapping (DCM) is a specialised intraoperative neuromonitoring technique used during spinal surgeries to identify and preserve the dorsal columns of the spinal cord, responsible for proprioception and fine touch sensation. This method involves electrically stimulating the spinal cord’s surface and recording responses to identify the functional areas of the dorsal columns. By accurately mapping these areas, surgeons can avoid damaging critical sensory pathways during procedures such as tumor resections or spinal cord decompressions. Dorsal column mapping is essential for minimising the risk of postoperative sensory deficits, ensuring the preservation of the patient’s quality of life by maintaining their sensory functions.
