Acute low back pain, defined as less than 6 weeks in duration, does not require imaging in the absence of "red flags" that may indicate a cause, such as fracture, infection, or malignancy. When imaging is indicated, it is important to rule out a host of abnormalities that may be responsible for the pain and any associated symptoms. A common mnemonic VINDICATE can help ensure a thorough consideration of the possible causes. Read More

The biomechanical stability of the spine is altered in patients with a rigid spine, rendering it vulnerable to fracture even from relatively minor impact. The rigid spine entities are ankylosing spondylitis (AS), diffuse idiopathic skeletal hyperostosis, degenerative spondylosis, and a surgically fused spine. The most common mechanism of injury resulting in fracture is hyperextension, which often leads to unstable injury in patients with a rigid spine per the recent AOSpine classification system.

"Swirl sign" is a relatively uncommon sign, seen on noncontrast CT scan in patients of head trauma who develop extradural hematoma. It has 2 components: hyperacute, which represents ongoing active intracranial bleed, and acute, which comprises surrounding hyperattenuated clotted blood. The importance of early identification of this sign by surgeons and aggressive surgical management might have a bearing on the prognosis and survival of the patients, as emphasized here by 2 clinical scenarios.

Spinal hematomas are a frequent indication for radiologic evaluation and can be a diagnostic dilemma for many radiologists and surgeons. There are four types of spinal hematomas: epidural, subdural, subarachnoid, and intramedullary (spinal cord) hematomas. Because they differ by their location in relationship to the meningeal membranes and spinal cord, unique radiologic appearances can be recognized to distinguish these types of spinal hemorrhage.

Department of Orthopedics, Seoul Sacred Heart General Hospital, Seoul, Korea.

Background: The incidence of cardiovascular and neurovascular diseases has been increasing with the aging of the population, and antiplatelet drugs (APDs) are more frequently used than in the past. With the average age of spinal surgery patients also increasing, there has been a great concern on the adverse effects of APD on spine surgery. To our knowledge, though there have been many studies on this issue, their results are conflicting. Read More

BACKGROUND Traumatic torcular herophili epidural hematoma is a rare and specific type of traumatic brain injury that is technically difficult to treat and, more critically, can lead to malignant encephalocele during the operation. CASE REPORT A 40-year-old man presented to our hospital 2 h after a motor vehicle crash. Emergency cranial CT showed a frontotemporal subdural hematoma; 3 h after the patient was admitted, the GCS score decreased to 8 and cranial CT re-examination showed that the frontotemporal subdural hematoma was significantly larger than before.

Background And Objectives: Guidelines regarding the role of repeated head computed tomography (CT) imaging in the nonoperative management of traumatic epidural hematomas (EDHs) do not exist. Consequently, some children may be exposed to unnecessary additional ionizing radiation.

Background: Spinal epidural hematoma (SEH) is a potentially devastating problem that requires rapid diagnosis and surgical intervention. A chronic course is rarely seen following SEH, and the clinical characteristics are quite different from acute cases. The epidemiology, clinical history, and radiologic findings of chronic SEH (CSEH) are not well understood, although the detection rate has increased with the widespread use of magnetic resonance imaging.

Department of Anaesthesiology and Surgical Oncology, Saifee Hospital, Mumbai, Maharashtra, India.

Coagulopathy either from the use of anticoagulant, antiplatelet, or thrombolytic medications or from underlying medical conditions is considered one of the major risk factors for epidural hematoma formation related to epidural catheter placement or removal. The American Society of Regional Anesthesia and Pain Medicine (ASRA) has laid down guidelines regarding timing of neuraxial blockade or removal of neuraxial catheters in patients receiving either antithrombotic or thrombolytic therapy. We present a case of acute onset of paraplegia because of an epidural hematoma following removal of the epidural catheter in a patient who was given the first dose of antithrombotic therapy after the removal of the epidural catheter as per the ASRA guidelines.

In blunt cerebrovascular injury, reported traumatic basilar artery occlusions have involved dissection of the basilar artery, distal embolization due to traumatic vertebral artery dissection, or entrapment of the basilar artery into the clivus fracture. To date, however, there are no reports of traumatic basilar artery entrapment without a clivus fracture. Here, we report the first case of traumatic basilar artery occlusion caused by entrapment into an originally existing bone defect. Read More
