To review fracture rates in patients who had X-rays of either the ankle or foot or both in the Emergency Department of a district hospital. ⋯ The approach to X-raying ankle and feet in this study is probably widespread, and Ottawa Ankle Rules still seem to be of limited use in diagnosing fractures. This low yield of positive X-ray could be accepted or a more sophisticated ankle rule introduced.

Fifth metatarsal fractures are common and the outcome has been reported; however, prospective studies reporting the functional outcome using validated questionnaires are lacking in the literature. The aims of this study were to determine whether fifth metatarsal fractures remain symptomatic in the medium term and whether the fracture type influences outcome. ⋯ While 25-33% of patients continue to experience pain at 1 year, <10% experience any limitation of their activities. At the final follow-up at 1 year, there were no significant differences in functional outcome by fracture type, gender or patient age. Patients should be advised about the likelihood of ongoing low-level symptoms, even after a year from injury in this previously presumed innocuous injury.

The purpose of this study was to describe four exceptional cases of Salter-Harris type III and IV fractures of the proximal phalanx of the hallux in young high-level gymnasts. All gymnasts underwent the same mechanism of injury of hyperadduction, which indicates a role of the abductor hallucis muscle in the genesis and displacement of these fractures. ⋯ Moreover, all the gymnasts had returned to pre-injury levels of sporting activity. To our knowledge, there are no previous studies that address these types of injuries and how they are handled in gymnasts.

Hemeproteins such as free myoglobin can undergo autoxidation and catalyse lipid peroxidation, increasing oxidative stress. Creatine phosphokinase (CPK) elevation is a marker for free myoglobin after myocyte damage. Since oxidative injury is a key mechanism of injury-related organ dysfunction, we hypothesised that serum CPK levels correlate with mortality and need for inotropic medication and duration of inotropic support, i.e. shock, among critically injured patients. ⋯ In critically injured patients, elevated serum CPK level is independently associated with mortality, need for inotropic medication, and duration of inotropic support. This study is the first to evaluate the relationship of CPK level and mortality in addition to surrogate measures of shock in a population of critically injured patients. If these associations are verified prospectively, there may be a role for treatment with hemeprotein reductants, such as paracetamol, to mitigate the effects of shock and end-organ dysfunction.

Posttraumatic immune disorder can cause complications including systemic inflammatory response syndrome (SIRS) and multiple-organ dysfunction syndrome (MODS). Cytotoxic granules containing perforin and granzyme-B (GrB) are released by cytotoxic CD8(+) T lymphocytes, NK and γδT cells after major trauma. This prospective clinical study was designed to analyze the association between these immune components and complications after major trauma. ⋯ Posttraumatic MODS is associated with early, sustained, and severe depression of lymphocytes.
