1. 6. The normal and ACL deficient knee : an in vivo three dimensional kinematic and electromyographic analysis

   Författare :Dan K Ramsey; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Knee; Tibia; Femur; Tibiofemoral contact points; Tibiofemoral kinematics; Anterior cruciate ligament; ACL injury; Knee brace; Knee instability; Bone pin; Magnetic resonance imaging; NM; Neuromuscular adaptation; Electromyography.;

   Sammanfattning : The overall aim of this thesis was to describe the in-vivo 3D kinematics of the normal and ACL deficient knee. Baseline data from normal controls were compared against the pathological knee to assess whether generic functional knee braces reduced abnormal displacements. Moreover, 3D bony contact movements were derived from MRI data. LÄS MER

3. 7. Sagittal plane knee translation in healthy and ACL deficient subjects : a methodological study in vivo with clinical implications

   Författare :Anil Vergis; Jon Karlsson; Linköpings universitet; []
   Nyckelord :anterior cruciate ligament; electrogoniometer system; gait; knee; kinematics; motion analysis; step ascent; step descent; translation; MEDICINE; MEDICIN;

   Sammanfattning : This study on human subjects, comprises of four cross sectional and one prospective cohort study. The general purpose of this work was to develop a technique for measuring in vivo, sagittal anterior-posterior translatory motions in the knee joint using a computerized electrogoniometer (CA-4000, OS Inc., Hayward CA, USA).

4. 8. Computerised Microtomography : Non-invasive imaging and analysis of biological samples, with special reference to monitoring development of osteoporosis in small animals

   Författare :Mats Stenström; Gudrun Alm Carlsson; Carl Carlsson; Jim Elliot; Linköpings universitet; []
   Nyckelord :Computed microtomography; CμT; signal-to-noise ratio SNR ; non-invasive monitoring; morphological changes; Gastrectomized Sprague-Dawley; osteoporosis; MEDICINE; MEDICIN;

   Sammanfattning : The use of Computerised microtomography (CμT) in biomedical research is well established, with most applications developed at synchrotron facilities. The possibility to non-invasively monitor morphological changes in biological samples, makes it an attractive technique in biomedicine. LÄS MER

5. 9. The effects of cyclosporin A on bone turnover and repair

   Författare :Anders Ekelund; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Cyclosporin A; osteoinduction; osteoconduction; bone turnover; fracture healing; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

   Sammanfattning : The effects of cyclosporin A on bone metabolism are unclear and controversial. The aims of this thesis were to study the effects of cyclosporin A on bone turnover and on different repair processes such as fracture healing, osteoinduction and osteoconduction. LÄS MER

7. 10. The influence of alcohol on bone metabolism and fracture healing

   Författare :Fredrik Nyquist; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kirurgi; traumatology; orthopaedics; Surgery; fracture prediction.; fracture healing; bone mineral density; Alcohol; post-traumatic osteopenia; fracture; ortopedi; traumatologi; Skeleton; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi;

   Sammanfattning : The influence of alcohol on bone metabolism, fracture and fracture healing was evaluated in men and male rats by measurements of bone mineral density (BMD), biochemical markers and biomechanical testings. Retrospectively, 199 male patients hospitalized for tibia shaft fractures were studied. Forty-nine were judged as problem drinkers. LÄS MER
