Comparative Study
Comparison of skin pressure measurements with the use of pelvic circumferential compression devices on pelvic ring injuries.
Pelvic circumferential compression devices are commonly used in the acute treatment of pelvic fractures for reduction of pelvic volume and initial stabilisation of the pelvic ring. There have been reports of catastrophic soft-tissue breakdown with their use. The aim of the current investigation was to determine whether various pelvic circumferential compression devices exert different amounts of pressure on the skin when applied with the force necessary to reduce the injury. The study hypothesis was that the device with the greatest surface area would have the lowest pressures on the soft-tissue. ⋯ Application of commercially available pelvic binders as well as circumferential sheeting commonly results in mean skin pressures that are considered to be above the threshold for skin breakdown. We therefore recommend that these devices only be used acutely, and definitive fixation or external fixation should be performed early as patient physiology allows. There may be some advantage of use of a simple sheet given its low cost, versatility, and ability to alter contact surface area.

With the increasing prevalence of total hip arthroplasty and the increasing longevity of patients with implants in situ, periprosthetic fractures of the proximal femur are seen with greater frequency. They represent a challenging surgical problem, requiring combined arthroplasty and trauma skills in a potentially compromised surgical bed. We present data from the 82 consecutive patients with periprosthetic fractures around the hip presenting to two NHS Foundation Trusts in the period January 2009 to February 2014. ⋯ Mean delay to surgery was 4.5 days in those with 1 year mortality, 4.16 days in those without (p=0.6203). The number of post-operative complications was not significantly positively correlated with increasing delay to surgery (Pearson correlation coefficient -0.04437). It would appear that a delay to order necessary equipment and obtain relevant surgical expertise for the treatment of these complex fractures is safe and not associated with increased mortality or post-operative complications.

A variety of systems have been applied to identify and address errors in the management of multiple trauma patients. This lack of standardisation represents a serious problem. ⋯ Measuring and recording the results is the first step on the way to improving the quality of care for trauma patients. A common language like the taxonomy of Joint Commission will help standardise patient safety data, thus improving the recording of incidents and their analysis and treatment.

Isolated fractures of the lower extremity are relatively common injuries while multifocal injuries resulting from high-energy trauma are less frequently encountered. Our objectives are to characterise patients who sustained multiple noncontiguous fractures and open fractures of the lower extremity, report the incidence of major complications, and identify factors that may contribute to complications and unplanned re-operations. ⋯ Patients with multiple non-contiguous lower extremity injuries associated with open fractures can expect complications including non-unions, deep infections, and painful implants. Nearly half of the patients will need further operative treatment.

Blast injuries from conventional and improvised explosive devices account for 75% of injuries from current conflicts; over 70% of injuries involve the limbs. Variable duration and magnitude of blast wave loading occurs in real-life explosions and is hypothesised to cause different injuries. While a number of in vivo models report the inflammatory response to blast injuries, the extent of this response has not been investigated with respect to the duration of the primary blast wave. The relevance is that explosions in open air are of short duration compared to those in confined spaces. ⋯ We report the development of a rodent model of primary blast limb trauma that is the first to highlight an important role played by blast wave duration and magnitude in initiating acute inflammatory response following limb injury in the absence of limb fracture or penetrating trauma. The combined biological and mechanical method developed can be used to further understand the complex effects of blast waves in a range of different tissues and organs in vivo.
