2. 1. Injectable Biomaterials for Spinal Applications

   Author : Alejandro López; Cecilia Persson; Håkan Engqvist; Andreas Boger; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; injectable; biomaterials; bone cement; vertebral compression fractures; spine; radiopacity; minimally invasive treatment; low-modulus cement; oligomer; PMMA; calcium phosphate; vertebroplasty; bone; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

   Abstract : The use of injectable biomaterials is growing as the demands for minimally invasive procedures, and more easily applicable implants become higher, but their availability is still limited due to the difficulties associated to their design.Each year, more than 700,000 vertebral compression fractures (VCF’s) are reported in the US and 500,000 VCF’s in Europe due to primary osteoporosis only.

4. 2. Calcium-Aluminate as Biomaterial : Synthesis, Design and Evaluation

   Author : Jesper Lööf; Håkan Engqvist; Sture Hogmark; Elis Carlström; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Calcium-aluminate; Biomaterial; Dental materials; Vertebroplasty; Chemically Bonded Ceramics; Synthesis; Biomaterials; Biomaterial;

   Abstract : In this thesis different aspects of calcium-aluminate (CA) as biomaterial are presented. Calcium aluminate is a chemically bonded ceramic with inherent properties making it suitable for use as biomaterial in some applications. READ MORE

5. 3. Bone-compliant cements for vertebral augmentation

   Author : Céline Robo; Cecilia Persson; Elizabeth Tanner; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone cement; low modulus; vertebroplasty; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

   Abstract : Acrylic bone cement based on poly(methyl methacrylate) (PMMA) is commonly used during vertebral augmentation procedures for the treatment of osteoporosis-induced vertebral compression fractures. However, the high stiffness of the cement compared to that of the surrounding trabecular bone is presumed to facilitate the formation of new fractures shortly after surgery. READ MORE

6. 4. Novel Materials and Implant Designs for the Treatment of Degenerative Disc Disease

   Author : Salim Ghandour; Cecilia Persson; Donal McNally; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Topology Optimization; Spine; Intervertebral Disc; Papain; Additive Manufacturing; Biomechanics; Bone Cement; PMMA; Calcium Phosphate; Cage; Fusion; Engineering Science with specialization in Biomedical Engineering; Teknisk fysik med inriktning mot medicinsk teknik;

   Abstract : The overarching objective of this thesis was to develop intervertebral implants for degenerated discs through design, fabrication, and mechanical validation. The research had four primary aims, each addressing different facets of implant development. READ MORE

7. 5. The acute osteoporotic vertebral compression fracture. Its natural course and characteristics

   Author : Nobuyuki Suzuki; Göteborgs universitet; []
   Keywords : Vertebral body fracture; Osteoporosis; Pain; Quality of life; Disability; Compression fracture; Prognosis; Treatment; Prevalent fracture; Epidemiology;

   Abstract : Aim: The overall aim of this thesis was to investigate the natural course and the characteristics of the acute osteoporotic vertebral compression fracture in order to better understand and improve treatment for this type of fracture. Patients and methods: Eligible patients were all patients over 40 years of age who sought medical care at the emergency unit at Sahlgrenska University Hospital (studies I-III) or referred to the X-ray Department at Capio Diagnostic Center (study IV) because of back pain with a radiographically-confirmed acute vertebral body fracture which resulted from a low energy trauma.
