Randomized Controlled Trial Comparative Study
Routine pin tract care in external fixation is unnecessary: a randomised, prospective, blinded controlled study.
Pin site infections are seen in up to 40% of external fixators (ExFix) and are therefore the most common complication with this device. There is no consensus in the literature as to the appropriate regimen for pin tract care and infection prevention. This study is the first intra-subject, randomised, prospective controlled trial comparing daily pin tract care to no pin tract care at all. ⋯ This study shows that routine pin tract care is unnecessary in external fixation treatment of injuries.

Helicopter Emergency Medical Services (HEMS) are highly resource-intensive facilities that are well established as part of trauma systems in many high-income countries. We evaluated the cost-effectiveness of a physician-staffed HEMS intervention in combination with treatment at a major trauma centre versus ground ambulance or indirect transport (via a referral hospital) in New South Wales (NSW), Australia. ⋯ Our investigation confirms a HEMS intervention is associated with improved mortality in trauma patients, especially in patients with serious injury and TBI. The improved benefit of HEMS in patients with serious injury and TBI leads to improved estimated cost-effectiveness.

The use of an intramedullary fibular allograft together with a locking plate fixation has been recently described in biomechanical studies to provide additional medial support and prevent varus malalignment for displaced proximal humeral fractures with promising results. The aim of this study was to evaluate the clinical and radiographic outcome of a locking plate with fibular allograft augmentation in unstable humeral fractures. ⋯ Locking plate with fibular graft augmentation is a safe and promising technique to support the humeral head and maintain reduction in the proximal humeral fracture with medial comminution.

In an attempt to explore new tools for constructing a model of blast injuries to the human mandible, a finite element method was used. This model allowed us to perform dynamic simulations and analyse the injury processes and severity of trauma to the human mandible from an explosion striking at the middle mandibular angle. ⋯ The finite element model was able to dynamically simulate the blast-initiated trauma processes to a human mandible, which allowed for investigation of the severity of damage to the mandible under different injury conditions. This model and the simulation method are conducive for applications in basic studies and clinical investigations of blast-initiated injury mechanisms of bone tissues.

The existing evidence regarding the management of quadriceps tendon rupture remains obscure. The aim of the current review is to investigate the characteristics, the different techniques employed and to analyse the clinical outcomes following surgical repair of quadriceps tendon rupture. An Internet based search of the English literature of the last 25 years was carried out. ⋯ It appears that the type of surgical repair does not influence the clinical results. The majority of the studies reported good or excellent ROM and return to the pre-injury activities. The overall rate of re-rupture was 2%.
