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

2. Altered body composition in adults with complex congenital heart disease
Sammanfattning : Introduction: Thanks to achievements in paediatric heart surgery and medicine, the population of adults with surgically repaired or palliated congenital heart defects is growing. Many of these adults have reduced exercise capacity, weaker muscular strength and shorter height, all of which suggest an altered body composition. LÄS MER
3. Changes in bone mass and skeletal structure in the postmenopausal period
Sammanfattning : The aim of this thesis was to evaluate long-term changes in bone mass and skeletal structure in the forearm in the peri- and postmenopausal period. 156 premenopausal women, at baseline aged 48 years, not taking medications and without disease processes known to interfere with bone metabolism, were followed through menopause by measurements of bone mass and skeletal structure at the cortical site of the distal radius by single photon absorptiometry, on average every second year until age 72.

4. Can Bone Void Fillers Carry Load? : Behaviour of Calcium Phosphate Cements Under Different Loading Scenarios
Sammanfattning : Calcium phosphate cements (CPCs) are used as bone void fillers and as complements to hardware in fracture fixation. The aim of this thesis was to investigate the possibilities and limitations of the CPCs’ mechanical properties, and find out if these ceramic bone cements can carry application-specific loads, alone or as part of a construct.

5. Organochlorines and bone : Effects of organochlorines on bone tissue morphology, composition and strength
Sammanfattning : From results presented during the last decade, it is obvious that the skeleton is a targetorgan for a number of persistent organochlorines. So far, however, little attention hasbeen paid to this subject. LÄS MER
