  1. 16. Quantification of skeletal, muscular and kinematics parameters in scoliosis : methodological and clinical studies

    Författare :Khaled Mohamed Diab; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Idiopathic scoliosis; new methods; scoliotic angle; vertebral body volume; intercostal muscle; ultrasonography; ground reaction force; centre of mass; centre of pressure; motor control;

    Sammanfattning : This dissertation presents new methods derived for precise evaluation of a number of anatomical and functional variables of the complex thoracospinal deformity in scoliosis. By consensus the scoliotic angle at the frontal plane is measured on radiographs using the Cobb method. LÄS MER

  3. 17. Aspects on the influence of the thoracic wall on the pathogenesis of idiopathic scoliosis

    Författare :Bo Sevastik; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Experimental and clinical studies were performed in order to study the possible influence of the thoracic wall on the pathomechanism of adolescent idiopathic scoliosis, IS. Experimental longitudinal elongation of one rib resulted in a deviation of the vertebra in the frontal plane to the contralateral side of the elongated rib, an anterior displacement in the sagittal plane and a rotation towards the convexity of the curve, thus a deviation identical to the 3-D configuration of the spine seen in IS.

  4. 18. Radiation dose and image quality in diagnostic radiology : optimization of the dose - image quality relationship with clinical experience from scoliosis radiography, coronary intervention and a flat-panel digital detector

    Författare :Håkan Geijer; Hans Ringertz; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Det är känt att röntgenstrålning kan orsaka cancersjukdomar, hudskador och andra sidoeffekter. Därför är det viktigt och även föreskrivet i lag att strålexpaneringen inom diagnostisk radiologi skall sänkas så långt som möjligt. Detta kallas på engelska ALARA-principen (As Low As Reasonably Achievable). LÄS MER

  5. 19. Functional ability in non-ambulatory people with Duchenne muscular dystrophy or spinal muscular atrophy assessed with the EK scale

    Författare :Birgit F Steffensen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Duchenne muscular dystrophy; EK scale; functional ability; natural history; nonambulatory stage; predictor; reliability; scoliosis; spinal muscular atrophy; treatment; validity.;

    Sammanfattning : Duchenne muscular dystrophy (DMD) and spinal muscular atrophy (SMA) are neuromuscular diseases characterised by profound global skeletal muscle weakness leading to severe physical disability. The EK scale, an instrument for assessment of functional ability in non-ambulatory people with DMD or SMA, was developed. LÄS MER

  7. 20. Aspects on bleeding and transfusion in elective orthopaedic surgery. Clinical and experimental studies

    Författare :Malin S Carling; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedic surgery; fibrinogen; factor XIII; surgical bleeding; transfusion;

    Sammanfattning : Background: Perioperative bleeding complications are associated with increased morbidity and mortality. One way to minimize perioperative bleeding and transfusion is to identify patients at risk of bleeding. Preoperative fibrinogen plasma concentration and factor XIII (FXIII) activity may be indicators of perioperative bleeding and transfusion. LÄS MER
