Thoracic spine stab injury with a retained knife.

A female was admitted to a Major Trauma Centre with an isolated thoracic spine stab injury involving a retained knife. The patient was haemodynamically stable with an unremarkable peripheral neurological examination. A CT scan with three-dimensional image reconstruction showed the knife blade lodged in the T11 vertebra with its tip close to the spinal cord, aorta and inferior vena cava. A multidisciplinary trauma team, including anaesthetists, vascular, neurosurgeons and general surgeons, agreed on the treatment strategy. The lodged knife was safely withdrawn in the operating theatre with the patient in a prone position under sedation and local anaesthesia. Following the procedure, neurological examination remained normal, and an MRI scan revealed no spinal cord injury. We discuss the management of penetrating spinal injuries, the importance of detailed preoperative imaging, timely multidisciplinary input and how to safely remove a knife when a prone position prevents standard airway management.
