Injury

Blunt thoracic aortic injuries, even though rare in incidence, carry significant mortality rates and their management still remains challenging. There have been major shifts in diagnosing and treating these injuries in the last 5 decades, which proved to be beneficial in terms of mortality and complications. Endovascular repair has been increasingly used for definitive treatment and its outcomes appear to be at least equally safe and effective as those of open repair. ⋯ Based on the studies analyzed, endovascular repair is increasingly being established as the choice of treatment, however, the conventional open surgical approach still remains a safe method for severe injuries; the mortality, complication rates and proven longterm results of the latter are continuously improving. Additionally, delayed repair, where appropriate, seems to be a safe option with very low mortality rates. Despite the encouraging short and midterm outcomes reported, endovascular treatment needs to be assessed in the longterm for more accurate conclusions to be drawn about its durability and safety.

Multicenter Study
Contemporary demographics and complications of patients treated for open ankle fractures.
Open ankle fractures are rare injuries with a high likelihood of wound complications and subsequent infections. There is limited information about the complications and outcomes of these injuries in different age groups. The aim of this study was to assess the contemporary demographics and complications related to this injury. ⋯ Interestingly, younger patients also had significantly more complications (p=0.024), suffered more often from chronic pain (p=0.003), and required more flap reconstructions (p=0.026), reoperations (p=0.026), and outpatient clinic visits (p=0.006). Open ankle fractures have a high complication rate and often require multiple surgical procedures. In young patients these injuries are more likely to be the consequence of high-energy trauma leading to more complications and subsequently increased healthcare resource utilisation.

Comparative Study
A biomechanical study of standard posterior pelvic ring fixation versus a posterior pedicle screw construct.
The purpose of this study was to biomechanically test a percutaneous pedicle screw construct for posterior pelvic stabilisation and compare it to standard fixation modalities. ⋯ The pedicle screw construct biomechanically compares to currently accepted methods of fixation for sacral fractures when the fracture is uncompressible. It should not be used for SI joint disruptions as one SI or an S1+S2 are significantly stiffer and cheaper.

Multicenter Study
The predictive value of multidetector CTA on outcomes in patients with below-the-knee vascular injury.
Multidetector computed tomographic angiography (MDCTA) has become the gold standard for the early assessment of lower extremity vascular injury. The objective of this study was to evaluate the predictive value of MDCTA documented vessel run-off to the foot on limb salvage rates after lower extremity vascular injury. ⋯ In this multicenter evaluation of patients undergoing MDCTA for suspected below-the-knee vascular injury, there was a stepwise increase in the need for operative intervention, fasciotomy and amputation as the number of patent vessels to the foot decreased.

To estimate sensitivity and specificity of CT and MRI examinations in patients with fractures of the proximal femur. To determine the interobserver agreement of the modalities among a senior consulting radiologist, a resident in radiology and a resident in orthopaedics surgery. ⋯ MRI was observed to have a higher diagnostic accuracy than CT in detecting occult fractures of the hip. Interobserver analysis showed high kappa values corresponding substantial agreement in both CT and MRI.
