The talus is the most proximal bone of the hindfoot that couples the foot to the leg. It is the second most common fracture of the tarsal bones, second in frequency to the calcaneous. ⋯ This article discusses fractures of the talus, including injuries to the talar neck, body, head, and processes. Although subtalar dislocations and osteochondral injuries are important topics, they are not addressed in this article.

Prognostic Value of Somatosensory-evoked Potentials and CT Scan Evaluation in Acute Traumatic Brain Injury.
The aim of this study is to assess whether a complete analysis of all early cortical somatosensory-evoked potentials (SEPs) components and computed tomography (CT) scan features can provide a better prognostic measure than the early cortical component N20/P25 alone, in patients with severe head injury. ⋯ Statistical analysis revealed a highly significant (P<0.0001) improvement in outcome prediction when the model includes a pool of amplitudes and latencies referred to different early-evoked components pN20, pP25, fP20, cP22, N30, P45, and N60, associated to CT scan hypodensity values, compared with the use of the cortical parietal N20/P25 alone.

Childhood maltreatment and combat posttraumatic stress differentially predict fear-related fronto-subcortical connectivity.
Adult posttraumatic stress disorder (PTSD) has been characterized by altered fear-network connectivity. Childhood trauma is a major risk factor for adult PTSD, yet its contribution to fear-network connectivity in PTSD remains unexplored. We examined, within a single model, the contribution of childhood maltreatment, combat exposure, and combat-related posttraumatic stress symptoms (PTSS) to resting-state connectivity (rs-FC) of the amygdala and hippocampus in military veterans. ⋯ Childhood trauma, combat exposure, and PTSS differentially predict fear-network rs-FC. Childhood maltreatment may weaken ventral prefrontal-subcortical circuitry important in automatic fear regulation, but, in a compensatory manner, may also strengthen dorsal prefrontal-subcortical pathways involved in more effortful emotion regulation. PTSD symptoms, in turn, appear to emerge with the loss of connectivity in the latter pathway. These findings suggest potential mechanisms by which developmental trauma exposure leads to adult PTSD, and which brain mechanisms are associated with the emergence of PTSD symptoms.

In a recent publication, 297 of 6450 (4.6%) military coalition deaths over ten years were reported to be due to junctional bleeding. The authors suggested that some of these deaths could have been avoided with a junctional haemorrhage control device. Prospectively collected data on all injuries sustained in Afghanistan by UK military personnel from 1 August 2008 to 31 July 2011 period were reviewed, using the UK Joint Theatre Trauma Registry. ⋯ Some potentially survivable deaths due to exsanguination may be amenable to proximal vascular control. Our study does not substantiate previous conclusions that this can be achieved through use of a groin junctional tourniquet. We believe there may be a role for more proximal vascular control of pelvic bleeding, and this merits further research.

Pain management is an important aspect of emergency care for children suffering traumatic injuries. ⋯ Few pediatric patients had pain scores documented and fewer received analgesics during air medical transport for injuries. Racial differences in analgesia seen in unadjusted analyses did not persist after controlling for confounders. Resources, training, and appropriate pain management protocols should be made available to facilitate pain assessment in children as a strategy for increasing appropriate analgesic use during transport.
