Stab wound to the intramedullary spinal cord: Presurgical and surgical management options for a retained blade to optimize neurological preservation

BACKGROUND: We present a rare case of an intraparenchymal nonmissile penetrating spinal injury (NMPSI) occurring at the T11 level in a patient presenting without neurological deficit. CASE DESCRIPTION: The patient sustained a knife wound that penetrated the lamina without incurring bony injury and entered the spinal cord at the T11 level. During surgery, the intramedullary penetration of the cord was confirmed, and following surgical removal of the knife, the patient fully recovered without losing any neurological function. CONCLUSIONS: The surgical management of NMPSI in patients who are neurologically intact is controversial. Here, we report surgical excision of a knife that penetrated the spinal cord at the T11 level, without the patient incurring further neurological deterioration.
