Hospital admission rates for a number of conditions have been linked to variations in the weather. It is well established that trauma workload displays significant seasonal variation. A reliable predictive model might enable targeting of high-risk groups for intervention and planning of hospital staff levels. To our knowledge there have been no systematic reviews of the literature on the relationship between weather and trauma workload, and predictive models have thus far been informed by the results of single studies. ⋯ Weather conditions may have a substantial effect on trauma workload independent of the effects of seasonal variation; the population studied and timecourse of weather events appear critical in determining this relationship. Methodological differences between studies limit the validity of conclusions drawn from analysis of the literature, and we identify a number of areas that future research might address.

This article proposes a counter-argument to standard Advanced Trauma Life Support (ATLS) training--which advocates bladder catheterisation to be performed as an adjunct to the primary survey and resuscitation for early decompression of the bladder and urine output monitoring. We argue the case for delaying bladder catheterisation until after definitive truncal Computed Tomography (CT) imaging. To reduce pelvic volume and associated bleeding, our trauma team delay catheter insertion until after the initial CT scan. ⋯ Venous, arterial and medullary injuries with associated bleeding may be potentiated by an increased pelvic volume with ring disruption, as well as a reduced pressure effect from retroperitoneal and intra-pelvic organs on bleeding sites. Various techniques are used to reduce intra-pelvic bleeding. For shocked patients who have sustained major pelvic injuries with no other signs of urinary tract trauma and minimal urine in the bladder on initial FAST scan, we advocate careful, aseptic Foley catheter insertion followed by bladder insufflation with 500-600 mL of Normal Saline (NS) and subsequent catheter clamping to tamponade pelvic bleeding.

We reviewed the functional outcome of 68 patients with open ankle fractures managed in an orthoplastic specialist centre. ⋯ Patients from groups S and R underwent more procedures. However, a similar outcome can be achieved, highlighting the importance of managing such injuries in an orthoplastic specialist centre.

Comparative Study
Biomechanical evaluation of two innovative locking implants for comminuted olecranon fractures under high-cycle loading conditions.
The relatively high complication rate after fixation of olecranon fractures has led to an increasing application of anatomically pre-contoured locking plate systems. The purpose of the present study was to conduct a biomechanical comparison of olecranon osteosyntheses by applying the Olecranon VA-LCP and the 3.5mm LCP Hook Plate (LCP, locking compression plate) to an unstable fracture model under high-cycle loading conditions. ⋯ A significantly higher biomechanical stability can be achieved in the fixation of unstable olecranon fractures by application of the Olecranon VA-LCP rather than the 3.5mm LCP Hook Plate.

For AO/OTA 31-A2 fractures (A2 fractures) treated with dynamic hip screw (DHS), postoperative lateral wall fracture (PLWF) is thought to be a major cause of femoral medialisation and reoperation. Though trochanter stabilising plate (TSP) had been reported to have a good effect in preventing femoral medialization, its effects and indication in A2 fractures remain controversial. We hypothesized that TSP may improve treatment outcomes in patients with high risk of postoperative lateral femoral wall fractures. The purpose of this study was to investigate (1) the main risk factors predictive of PLWF in A2 fractures and, (2) whether TSP can improve treatment outcomes in patients with high risk of PLWF. ⋯ Lateral wall thickness is the main risk factor for PLWF in A2 fractures treated with DHS. Use of TSP in A2 fractures with critical thin lateral wall thickness <2.24 cm can significantly decrease the lag screw sliding distances, PLWF rate and reoperation rate.
