Randomized Controlled Trial
Diagnostic performance of the Bernese versus Ottawa ankle rules: Results of a randomised controlled trial.
The Ottawa ankle rules (OAR) brought about a reduction of radiographs on the Emergency Department (ED). However, still 50% of patients with ankle injuries undergo unnecessary radiography. Compared to the OAR, the Bernese ankle rule (BAR) has an acclaimed 84% reduction in radiography without loss of sensitivity. The primary aim of this study was to compare the diagnostic accuracy and reproducibility of both rules. Furthermore, the ability of triage nurses to accurately interpret the BAR was assessed. ⋯ Both rules showed comparable reproducibility. Although the BAR showed a superior specificity compared to the OAR, its sensitivity was too low to promote clinical use. The triage nurses demonstrated too low sensitivity on both rules to allow safe application. Therefore, the OAR remain the decision rules of choice for ankle injuries despite its modest 'ruling out' capacity.

Femoral neck nonunion (FNN) is a potential complication in patients with displaced femoral neck fractures, occurring in 33%. This may lead to early hip dysfunction or arthroplasty. Combination of modified free vascularized fibular grafting (FVFG) and a reverse LISS may provide a reasonable means to salvage a painless, functional and native hip. ⋯ The Harris hip scores (HHS) were improved 36.6 points on average (59.6 points preoperatively to 96.2 points postoperatively). No incidences of osteonecrosis of the femoral head were observed. The combined modified FVFG and reverse LISS plating is a suitable procedure for the management of femoral neck nonunion in patients younger than 30 years, especially for those patients with a revision history.

Total radiation exposure accumulated during circular frame treatment of distal tibial fractures was quantified in 47 patients treated by a single surgeon from February 2007 until Oct 2010. The radiation exposures for all relevant radiology procedures for the distal tibial injury were included to estimate the radiation risk to the patient. The median time of treatment in the frame was 169 days (range 105-368 days). ⋯ Radiation exposure during treatment of distal tibial fractures with a circular frame in this group was well within accepted safe limits. The fact that use of CT was the only significant predictor of overall exposure serves as a reminder to individually assess the risk and utility of radiological investigations on an individual basis. This is consistent with the UK legal requirements for justification of all X-ray imaging, as set out in the Ionising Radiation (Medical Exposure) Regulations 2000 [1].

Globally, injury is the fourth major cause of death and the third leading contributor to Disability Adjusted Life Years lost due to health conditions, with the greatest burden borne by low-middle income countries (LMICs) where injury data is scarce. In the absence of effective vital registration systems, mortuaries have been shown to provide an alternative source of cause of death information for practitioners and policy makers to establish strategic injury prevention policies and programs. This evaluation sought to assess the feasibility of implementing a standardised fatal injury data collection process to systematically collect relevant fatal injury data from mortuaries. The process evaluation is described. ⋯ The mortuary has been shown to be a potential data source for identifying injury deaths and their circumstances and monitoring injury trends and risk factors in LMICs. However, further piloting is needed, including in rural areas and training of forensic pathologists and data-recorders to overcome some of the difficulties experienced in the pilot countries. The key to attracting ongoing funding and support from governments and donors in LMICs for fatal injury surveillance lies in further demonstrating the usefulness of collected data.
