The biomechanical properties of extra-articular fractures of the distal humerus have not been researched sufficiently. The aim of the study was to examine three different models of osteosynthesis for extra-articular distal humerus fractures. Osteosynthesis with two parallel or perpendicular plates is a common method of osteosynthesis for those fractures. We wanted to examine the biomechanical performance of a newly designed Y plate, and compare it to the previously used osteosynthesis methods. ⋯ The displacements that appeared in all three plating systems are minimal and within the limits that meet the requirements of sufficient biomechanical stability in the usual time for the healing of fractures in that region. The newly designed Y-shaped plate for extra-articular fractures of the distal humerus is a possible alternative to the usual method of osteosynthesis with two plates in the case of an extra-articular fracture of the distal humerus. Further biomechanical studies are needed for a decisive conclusion.

Bone electrical potentials change with the force applied. Also, fracture alters the bone electrical potential, so it becomes more electronegative. These potentials have an important role in fracture healing, bone growth and remodelling. Literature data on the influence of fracture operative treatment on bone electrical potentials, and possible consequences of this influence, are sparse. The objective of this study was to establish a method of intraoperative bone potential measurement, and to try to find a correlation between electrical potential and fracture type, osteosynthesis method and prognosis. ⋯ Bone potentials, caused by fracture, can be measured intraoperatively; the operative procedure appears to influence their generation. Measured potentials depend on the fracture type, and could be correlated with prognosis.

We report on 2 cases of hyperextension/valgus elbow injuries in two adult male national team water polo goalkeepers. Both were healthy and had never sustained any major injuries of the elbow. ⋯ Different medical treatment protocols of these injuries possibly have led to different outcomes, with one of them developing osteochondritis dissecans (OCD). Inadequate medical treatment of acute impact elbow injuries could lead to osteochondritis disecans of the elbow in top-level adult male water polo goalkeepers.

Thoracic injury during warfare is associated with a high incidence of morbidity and mortality. This study examines the pattern and mortality of thoracic wounding in the counter-insurgency conflicts of Iraq and Afghanistan, and outlines the operative and decision making skills required by the modern military surgeon in the deployed hospital setting to manage these injuries. ⋯ Blast is the main mechanism of thoracic wounding in the recent conflicts in Iraq and Afghanistan. Thoracic trauma in association with severe head or abdominal injuries are predictors of mortality, rather than thoracic injury alone. Deploying surgeons require training in thoracic surgery in order to be able to manage patients appropriately at Role 3.

The primary goal of this study was to compare the chest wall thicknesses (CWT) at the 2nd intercostal space (ICS) at the mid-clavicular line (MCL) and 5th ICS at the mid-axillary line (MAL) in a population of patients with a CT confirmed pneumothorax (PTX). This result will help physicians to determine the optimum needle thoracostomy (NT) puncture site in patients with a PTX. ⋯ This study confirms that a 5.0-cm catheter would be unlikely to access the pleural space in at least 1/3 of female and 1/10 of male Turkish trauma patients, regardless of the puncture site. If NT is needed, the 5th ICS-MAL is a better option for a puncture site with thinner CWT.
