Minimal Invasive Fixation of Hamate Hook Fractures Through a Dorsal Percutaneous Approach Using a Mini Compression Screw: An Experimental Feasibility Study.

Purpose: Isolated fractures of the hamate hook can be treated by conservative or surgical means. Because nonoperative treatment is associated with high nonunion rates, surgical treatment with open reduction and internal fixation through a palmar approach is often preferred. The aim of this study was to refine surgical treatment of hamate hook fractures using a cannulated mini compression screw through a dorsal percutaneous approach.

A comparison of seal in seven supraglottic airway devices using a cadaver model of elevated esophageal pressure.

Background: Supraglottic airway devices are increasingly important in clinical anesthesia and prehospital emergency medicine, but there are only few data to assess the risk for aspiration. We designed this study to compare the seal of seven supraglottic airway devices in a cadaver model of elevated esophageal pressure.

Methods: The classic laryngeal mask airway, laryngeal mask airway ProSeal, intubating laryngeal mask airway Fastrach, laryngeal tube, laryngeal tube LTS II, Combitube, and Easytube were inserted into unfixed human cadavers with an exposed esophagus that had been connected to a water column of 130 cm height.

[Continuing medical education in Aesthetic Medicine: hands--on course on the usage of hyaluronic acids of different particle size on anatomic preparations].

The Division of Evidence Based Medicine (dEBM), Clinic for Dermatology, Venerology and Allergology, Charité--Universitätsmedizin Berlin, offers on a regular basis workshops focusing on different areas of aesthetic medicine. Once a year a joint course is provided in cooperation with the Institute of Anatomy, offering the participants the possibility to improve their injection techniques as well as their knowledge on the facial anatomy. This course is focused on treatment with hyaluronic acids of different particle size.

[Optimization of conventional X-ray images for the detection of hook of hamate fractures].

Fractures of the hook of the hamate are a rare event. The fracture cannot always be detected clinically and standard radiographs do not always provide an overlap-free image of the hook of the hamate, so that fractures can easily be overlooked. The objective of the present study was to examine if the sensitivity of detecting hamulus ossis hamati fractures can further be improved by a modified conventional radiographic projection.

Cribra orbitalia visualized in computed tomography.

Cribra orbitalia are sieve-like lesions of the orbital roof. While common in historic skulls, they have long been absent in those examined in the last decades. Only recently we found low-grade cribra orbitalia in some contemporary cases.
