We evaluated 4 different fixation devices for the reconstruction of a standardised Bryan and Morrey capitellar shear fracture in a sawbone model. Outcome measurements were the quality of reduction, time for reconstruction and stability. ⋯ When using four different fixation devices, the fixation of standardised Bryan and Morrey type I fractures in the sawbone model differs when it comes to the time needed for reduction, but not in the quality of reduction. Stability was the same for the implants used, except for the K-wires. There is no argument in favour one of the screw implants over another in clinical use.

All orthopaedic and trauma surgeons attend educational events throughout their careers. Many surgeons find that when they return to practice they are unable to put into effect those things that they have learned. ⋯ The commonest barrier amongst all surgeons is not having contact with a suitable patient to treat with their new knowledge and skills. Inability to get access to equipment and facilities is a major barrier for many surgeons especially in the developing world. This has profound implications for organizers of educational events that will need to incorporate strategies into their educational planning to help surgeon learners avoid or overcome barriers.

Patients with pulmonary contusion (PC) are at increased risk of development of complications and death after trauma. The early diagnosis and determination of severity of PC could improve clinical outcomes. The aim of the study was to determine the diagnostic value of ischaemia-modified albumin (IMA) in a PC model in rats. ⋯ Our preliminary findings suggest that there is no significant change of serum IMA levels in the acute phase of PC induced by blunt chest trauma.

Comparative Study
A comparative study of the mortality rate of rats receiving a half lethal dose of fat intravenously: under general anaesthesia versus under spinal anaesthesia.
There is no data that demonstrates what anaesthesia is suitable for patients who have a high risk of fat embolism syndrome (FES). We investigated the mortality rates of rats that received a half lethal dose (LD(50)) of fat by intravenous injection after induction of general or spinal anaesthesia. ⋯ It is feasible to assess the efficacy of various treatments for FES by comparing the mortality rates of animals after injection of an LD(50) of fat. The mortality rate of rats was lower when FES was induced under general anaesthesia than under spinal anaesthesia which implies that general anaesthesia is superior to spinal anaesthesia for patients who have a high risk of FES.

Despite the explanations put forth in many studies regarding histopathological evidence of the inflammatory stage related with the infusion of dimethyl sulfoxide (DMSO) in the vessel wall and its lumen, there has been no research to evaluate its neural toxicity when it is infused via the intracarotid route. This study was designed to evaluate the possible neurotoxic effects of DMSO on the closer and distant brain tissue and carotid artery when it was slowly infused into the internal carotid arteries of the rats. ⋯ This experimental study suggested that DMSO has no toxic effect on the neural and arterial tissues of rats when it is slowly infused into the carotid artery.
