1. 31. Arthroscopic Bankart reconstruction using different absorbable tacks. The clinical results, radiographic findings and effect on calcaneal bone mineral

   Författare :Anna Elmlund; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; shoulder dislocation; arthroscopic; dislocation arthropathy; BMA;

   Sammanfattning : ABSTRACT The aim of the thesis was to explore the clinical and radiographic results after post- traumatic anterior shoulder instability treated with arthroscopic Bankart surgery using absorbable tacks with different compositions. Further aims were to explore possible effects on bone mineral in the heel bone and health-related quality of life after a shoulder-stabilising surgical procedure. LÄS MER

3. 32. Effects of growth hormone on bone tissue in transgenic mice

   Författare :Jonas Sandstedt; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; bone; ovariectomy; orchidectomy; growth; Interleukin-6; titanium; transgenic mice;

   Sammanfattning : Growth hormone (GH) affect bone-tissue in both humans and rodents. Also sex steroids are important for growth and the maintenance of normal bone physiology. The specific aims of this study were to investigate how high levels of GH affects bone tissue in mice and to determine whether these effects are dependent on an intact gonadal function. LÄS MER

4. 33. Anterior cruciate ligament reconstruction surgery, aspects of graft choice, graft fixation and bone mineral loss

   Författare :Sven Stener; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anterior cruciate ligament; Reconstruction; Revision; PLLA; Bone mineral areal mass; DEXA;

   Sammanfattning : The aim of this thesis was to measure bone mineral changes in the calcanei, hips and lumbar spine of patients reconstructed with bone-patellar tendon-bone (BPTB) or hamstring tendon (HT) autografts following anterior cruciate ligament (ACL) injury. Furthermore, the aim was to compare the clinical results after ACL revision reconstruction with either reharvested ipsilateral or contralateral BPTB autografts. LÄS MER

5. 34. Defining the clinical usefulness of vertebral fracture assessment

   Författare :Lisa Johansson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vertebral fracture; vertebral fracture assessment; osteoporosis; DXA; HRpQCT; bone microindentation; mild vertebral fracture; physical function; fracture risk; incident fracture; older women;

   Sammanfattning : Objective: Vertebral fractures (VFs) are the most common osteoporotic fracture and among the strongest predictors for future fracture. VFs can be identified by vertebral fracture assessment (VFA) from lateral spine imaging (LSI) by dual-energy X-ray absorptiometry (DXA). LÄS MER

7. 35. Bone Mineral Density Determination in Children. Evaluation of a novel method and application to Duchenne muscular dystrophy

   Författare :Ann-Charlott Söderpalm; Göteborgs universitet; []
   Nyckelord :adolescents; age- and gender-matched; Becker; bone densitometry; bone markers; bone mineral density; calciotropic hormones; children; DXA; DXL; Duchenne; glucocorticoids; muscular dystrophy; normative; reference values; skeleton;

   Sammanfattning : Aims: The overall aims of this thesis were to evaluate the dual-energy X-ray and laser (DXL) method for bone densitometry measurements of the calcaneus in children, to provide reference data for bone mineral density (BMD) in the heel bone in young children and to apply the DXL technique to patients with Duchenne muscular dystrophy (DMD) and conduct a survey about bone health of DMD patients. Study populations and methods: The DXL Calscan method was modified and adapted for measurements in children and applied to bone densitometry in all subsequent studies. LÄS MER
