Placement of thoracic pedicle screws is a technically demanding procedure. The risk of thoracic pedicle breaches range from 6.5 to 41%. Current image guidance systems consist of computer based systems utilizing preoperative CT scans or 2D/3D intraoperative fluoroscopy. ⋯ The iCT based spinal neuronavigation system allowed for highly safe and accurate placement (97.3%) of thoracic pedicle screws in our institution with no neurovascular injury reported.

Traumatic extradural haematoma following a severe head injury is well documented in neurosurgical literature. We report a case of traumatic extradural haematoma which initially was concealed by the high intracranial pressure (ICP) and revealed after the contralateral decompressive craniectomy. A 21-year-old roofer sustained severe head injury from a fall. ⋯ The second surgery demonstrated a bleeding middle meningeal artery associated with the left temporal bone fracture. The clinical sequence of events, radiological and operative findings revealed this to be a traumatic extradural haematoma sustained at the initial trauma. This was revealed after the tamponade effect was released from the initial decompressive craniectomy on the contralateral side.
