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.

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.

To present the accuracy of reduction, complications and results two years after open reduction and internal fixation of displaced acetabular fractures involving the anterior column (AC) through the Pararectus approach. Frequencies for conversion to total hip replacement in the early follow up, the clinical outcome in preserved hips, and the need for an extension of the approach (1st window of the ilioinguinal approach) are compared to the literature about the modified Stoppa approach. ⋯ In the treatment of acetabular fractures involving the anterior column the Pararectus approach allowed for anatomic restoration with minimal access morbidity. Results obtained by means of the Pararectus approach after two years at least parallel those reported after utilisation of the modified Stoppa approach. In contrast to the modified Stoppa approach, a relevant extension of the Pararectus approach was almost not necessary.

Defects of the Achilles tendon region still represent a tricky issue in lower limb surgery. Among the several reconstructive possibilities, local propeller perforator flaps have gained popularity in the last decade. ⋯ Although the surgical technique requires much care and skill, including an extremely gentle dissection of perforator vessels, local propeller flaps should be considered the first-line choice for reconstruction in small-to-medium size soft-tissue defects in the Achilles region.
