BACKGROUND Metaphyseal forearm fractures are a common pathology in any emergency department. The standard diagnostic procedure involves X-rays of the forearm and wrist. As former studies have shown that these fractures can be visualized using ultrasound, we compared the accuracy of sonographic and X-ray diagnostics. METHODS From January 2007 to May 2008,(More)
AIM OF THE STUDY The exact determination of the extent of deformities in juvenile proximal humerus fractures is difficult with plain x-rays. The aim of this study was to find out whether proximal humerus fractures can be diagnosed and the extent of the deformity can be detected by ultrasonography. PATIENTS AND METHODS In a prospective, multicentre trial(More)
OBJECTIVE Metaphyseal forearm fractures are very common in childhood. Radiography of the wrist is the standard diagnostic procedure. The aim of our study was to evaluate and confirm the safety and applicability of the ultrasound diagnostic procedure in comparison to x-ray diagnosis. METHODS We investigated 76 patients aged between 1 and 14 years. After(More)
PURPOSE Metaphyseal forearm fractures are a common pathology in any emergency department. The standard diagnostic procedure is an X-ray of the forearm and wrist. Former studies have shown that these fractures can be visualized by ultrasound. The intention of this study was to evaluate the safety and reliability of the ultrasound diagnostic procedure in(More)
BACKGROUND The effectiveness of e-learning for reporting of x-ray-findings in a prospective, randomized trial was tested. MATERIAL AND METHODS Twenty advanced medical students were randomized into two groups. The test group practiced 4-6 hours with the newly developed software, the control group used conventional learning material. Afterwards, a test was(More)
BACKGROUND In the clinical evaluation of femoroacetabular impingement (FAI), there is a lack of quantitative, reliable and informative assessment methods for the overall functional capability of an individual. OBJECTIVE We compared clinical and radiological measurements of the hip joint with a new methodology based on the concept of 3-dimensional(More)
PURPOSE The objective of our study was to evaluate the safety and accuracy of ultrasound (US) compared to standard radiographs in diagnosing supracondylar fractures (SCFs) of the humerus in children. PATIENTS AND METHODS A total of 106 children (aged between 1 and 13 years) with clinically suspected SCF of the humerus were primarily examined by US(More)
OBJECTIVES Modern orthopaedic surgery provides a variety of techniques for cartilage repair. Despite comprehensive scientific data about the single procedures, there is little experience with the combination of these methods. Inspired by a case from our clinic, we performed a PubMed based literature search about the combination of cartilage restoration(More)
AIM Distal forearm fractures are very common in childhood. Radiography of the wrist is the standard diagnostic procedure. But because of higher sensitivity of growing bones to ionising radiation the diagnostic use of X-rays should be minimised as much as possible. Recent studies have shown that distal forearm fractures in children can be safely and reliably(More)
