Gunshot wound (GSW) to the spine which was earlier common in the military population is now being increasingly noted in civilians due to easy availability of firearms of low velocity either licensed or illegal combined with an increased rate of violence in the society. Contributing to 13% to 17% of all spinal injuries, the management of complex injury to the spine produced by a GSW remains controversial. Surgery for spinal cord injuries resulting from low velocity GSWs is reserved for patients with progressive neurologic deterioration, persistent cerebrospinal fluid fistulae, and sometimes for incomplete spinal cord injuries. Surgery may also be indicated to relieve active neural compression from a bullet, bone, intervertebral disk, or a hematoma within the spinal canal. Spinal instability rarely results from a civilian GSW. Cauda equina injuries from low velocity GSWs have a better overall outcome after surgery. In general, the decision to perform surgery should be made on consideration of multiple patient factors that can vary over a period of time. Although there have been plenty of individual case reports regarding GSW to the spine, a thorough review of unique mechanical and biological factors that affect the final outcome has been lacking. We review the key concepts of pathogenesis and management of GSW to the spine and propose an algorithm to guide decision making in such cases.
Orbital roof fractures after a blunt injury are an uncommon complication of trauma. Traumatic encephaloceles in the orbital cavity are even rarer, with only 15 cases published till date. Raised intraorbital pressure leading to irreversible damage to the optic nerve can be prevented by early diagnosis and management. Orbital computed tomography (CT) with thin axial and coronal sections is helpful in trauma patients with a concurrent orbital trauma. Decompression of the orbital roof is the key step in surgical treatment and should be performed in every case. Repairing the orbital roof has to be performed to avoid transmission of variation in the intracranial pressure to the orbit. We present a case of traumatic orbital encephalocele who underwent surgical treatment via a frontobasal approach with evacuation of the contused herniated brain and reconstruction of the orbital roof using temporalis fascia which is readily available in contrast to costly materials like titanium mesh, screws, bone powder, fibrin glue, and so on, which are not easily available in every hospital. Rapid resolution of proptosis and visual symptoms along with excellent cosmetic outcome was seen at follow-ups after three and nine months. We emphasize the early diagnosis of this rare condition and also emergency treatment to prevent permanent visual loss as well as to achieve good cosmetic results.
Twenty-three children under the age of 6 1/2 years developed immediate unilateral weakness after an apparently minor head injury. Computed tomography disclosed a hypodense lesion in the basal ganglia. The lesion appeared to be caused by an infarct in the basal ganglia. All but one of the children recovered completely within 4 months.
Abnormalities of blood coagulation are frequently found in patients following traumatic brain injury. Exposure to thromboplastin, which is abundant in brain, plays an important role in initiating coagulopathy. Eighty patients of moderate-to-severe head injury were screened for platelet count, prothombin time (PT), activated partial thromboplastin time (a-PPTK), fibrinogen degradation product levels (FDP), D-dimer levels, and disseminated intravascular coagulation scores (DIC), calculated within the first 24 hours of injury. Increased consumptive coagulopathy at admission, as reflected by high DIC scores, predicted mortality in both moderate and severe head injury patients with a high degree of accuracy (p < 0.001). Similarly, increased PT, FDP, and D-dimer values correlated with higher mortality in both groups, but platelet counts and a-PPTK values correlated with mortality only in the severe head injury group. From this study we conclude that hemostatic abnormalities are independent predictors of early mortality in moderate-to-severe head injury patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
