2. 1. Risk factors for bone fragility and fracture in postmenopausal women

   Author : Ola Svejme; Ortopedi - klinisk och molekylär osteoporosforskning; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone Fragility; Fracture; Osteoporosis; Bone Mineral Density BMD ; Menopause; Physical activity; Bone Strength; Bone Size; Bone Densitometry;

   Abstract : The aim of this thesis was to evaluate risk factors for bone fragility and fractures in postmenopausal women in a long-term perspective. The study period spanned from the age of 48 to age 82 and is thus unique in its length. The studied sample was homogeneous and consisted of 390 north European women from a population-based cohort.

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

   Author : Ann-Charlott Söderpalm; Göteborgs universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

5. 3. Bone mass in young adults - determinants and fracture prediction

   Author : Henrik Düppe; Ortopedi - klinisk och molekylär osteoporosforskning; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Skelett; rheumatology locomotion; muscle system; Skeleton; Fracture prediction.; Bone mass; Osteoporosis; Bone densitometry; muskelsystem; reumatologi;

   Abstract : Bone mass in adolescents and young adults was studied with regard to its age-related change and its determinants. Methodological aspects of bone mass measurements and their ability to predict future fractures were investigated. READ MORE

6. 4. Primary Hyperparathyroidism - Aspects on skeletal Involvemnt and PTH levels after Surgery

   Author : Erik Nordenström; Lund Kirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; orthopaedics; Surgery; PTH infusion; PTH levels; Densitometry; Bone density; Primary hyperparathyroidism; Skeletal;

   Abstract : The aim of this thesis was to evaluate risk factors for fractures in patients with primary hyperparathyroidism (pHPT), to study the association between preoperative variables and postoperative changes in bone density and to investigate long-term changes and peripheral PTH sensitivity in patients with elevated PTH levels after surgery. 203 pHPT patients were investigated with regard to clinical and biochemical variables and bone density.

7. 5. New polymer materials in total hip arthroplasty. Evaluation with radiostereometry, bone densitometry, radiography and clinical parameters

   Author : Georgios Digas; Göteborgs universitet; []
   Keywords : Total hip arthroplasty; polyethylene; bone cement; wear; fixation; and radiostereometry.;

   Abstract : Aims: To evaluate the outcome of different types of polyethylene, bone cements and one design of uncemented fixation with porous and ceramic coating using radiostereometry, bone densitometry, conventional radiography and clinical parameters.Materials and methods: Study 1: 201 patients were extracted from 5 prospective randomised studies to evaluate femoral head penetration at two years with radiostereometry in four basic designs, cemented Lubinus and Reflection cups, uncemented Trilogy and Reflection cups.
