2. 21. On Virtual Surgical Planning in Cranio-Maxillofacial Surgery

   Author : Johanna Nilsson; Andreas Thor; Risto Kontio; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Virtual surgical planning. Computer assisted planning. 3D computer model. Orbital segmentation. Craniomaxillofacial surgery planning. Haptics.; Oral and Maxillofacial Surgery; Käkkirurgi;

   Abstract : The complex three-dimensional (3D) anatomy of the cranio-maxillofacial (CMF) region makes surgery a challenging task. Virtual surgical planning (VSP) has the potential to increase accuracy, reproducibility and shorten operation time. READ MORE

4. 22. Differentiation of Human Dermal Fibroblasts and Applications in Tissue Engineering

   Author : Pehr Sommar; Gunnar Kratz; Thomas Hansson; Anders Lindahl; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue Engineering; Human Dermal Fibroblasts; Differentiation; Adipogenesis; Chondrogenesis; Endotheliogenesis; Osteogenesis; Plastic surgery; Plastikkirurgi;

   Abstract : Tissue engineering applies principles of biology and engineering to the development of functional substitutes for damaged or lost tissues. Tools for the neo-generation of tissue in tissue engineering research include cells, biomaterials and soluble factors. READ MORE

5. 23. Cervical Radiculopathy. Effects of Surgery, Physiotherapy or Cervical Collar. A prospective, randomised study

   Author : Liselott Persson; Neurokirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; headache.; posturography; neck mobility; strength; SIP; randomised trial; cervical collar; physiotherapy; anterior cervical fusion; Cervical radiculopathy; neck pain; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

   Abstract : The efficacy of surgery, physiotherapy or a cervical collar in the treatment of chronic cervicobrachial pain of radicular origin was evaluated in a prospective, randomised study comprising 81 patients of both sexes, 28-64 years of age, referred for possible neurosurgical treatment. After neurological and radiological examination and giving their informed consent, they were randomised to one of the three treatments. READ MORE

6. 24. Chronic anterior cruciate ligament tear : knee function and knee extensor muscle size, morphology and function before and after surgical reconstruction

   Author : Lars-Gunnar Elmqvist; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; knee joint; ligaments; articular; surgery; muscle fibre; isokinetics; exercise therapy; muscular atrophy; electromyography;

   Abstract : Knee function was evaluated by knee score, activity level, clinical findings and performance tests, muscle size by computerized tomography (CT), morphology by light (LM) and electron microscopy (EM), muscle function by electromyography (EMG) and isokinetic performance in 29 patients with chronic anterior cruciate ligament (ACL) tear. Preoperatively CT disclosed a significant mean atrophy of the quadriceps and nonsignificant changes of the other muscle areas of the injured leg. READ MORE

7. 25. Metal artifacts in computed tomography : impact of reduction methods on image quality and radiotherapy treatment planning

   Author : Karin Andersson; Per Thunberg; Eva Norrman; Jan Persliden; Anders Tingberg; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; computed tomography; metal artifacts; image quality; visual grading analysis; radiotherapy; proton therapy; hip prosthesis; dental implants;

   Abstract : Degradation of image quality by metal artifacts is a common problem in computed tomography (CT) imaging, which can limit the diagnostic value of a CT examination and also introduce inaccuracies in radiotherapy (RT) treatment planning. In recent years, commercial metal artifact reduction (MAR) methods have been launched by several CT vendors. READ MORE
