  2. 1. Re-interventions after endovascular aortic repair: clinical and experimental studies

    Author : Håkan Roos; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EVAR; stent graft; blood flow; displacement forces; aortic aneurysm; angulation; reoperation;

    Abstract : Background: Endovascular aortic repair (EVAR) has lower morbidity and mortality than open surgery. Late complications and re-interventions are more common, however, and the timing of different re-interventions and their respective underlying causes are not fully understood. READ MORE

  4. 2. Spontaneous correction of fracture deformity : a study in the rat

    Author : Jian Li; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Fracture healing; bone modeling; bone turnover; GAP-43; PGP 9.5; CGRP;

    Abstract : The aim of the present study was to elaborate a model in the rat permitting analysis of bone modeling to correct fracture deformity. Among conceivable regulators of this process, the study focused on the peripheral nervous system by analyzing markers of regenerating (GAP-43), mature (PGP 9.5) and sensory (CGRP) nerve fibers at the fracture site.

  5. 3. Interactive 3D Image Analysis for Cranio-Maxillofacial Surgery Planning and Orthopedic Applications

    Author : Johan Nysjö; Ingela Nyström; Filip Malmberg; Ida-Maria Sintorn; Jayaram K. Udupa; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; medical image analysis; interactive segmentation; volume rendering; computed tomography; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Modern medical imaging devices are able to generate highly detailed three-dimensional (3D) images of the skeleton. Computerized image processing and analysis methods, combined with real-time volume visualization techniques, can greatly facilitate the interpretation of such images and are increasingly used in surgical planning to aid reconstruction of the skeleton after trauma or disease.

  6. 4. Static and Dynamic Load Response of the Lumbar Spine in Flexion

    Author : Anna-Lisa Osvalder; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomechanical response; flexion-distraction injuries; injury; ; experimental methods; spinal segments;

    Abstract : The aims of this study were to develop experimental methods for static and dynamic loading of spinal segments in vitro that would simulate flexion-distraction injuries (lap seat-belt injuries) and increase knowledge about the biomechanical response and the mechanisms of injury of the lumbar spine under static and dynamic (transient) loads in flexion. The experiments were carried out on the lumbar functional spinal unit (FSU) consisting of two adjacent vertebrae, the intervertebral disc and all intervening ligaments. READ MORE

  7. 5. Fractures of the distal radius : Factors related to radiographic evaluation, conservative treatment and fracture healing

    Author : Albert Christersson; Sune Larsson; Bengt Sandén; Karl-Åke Jansson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Distal radius fractures (DRFs) are one of the most common injuries encountered in orthopaedic practise. Such fractures are most often treated conservatively, but surgical treatment has become increasingly common. READ MORE
