  1. 1. Injectable calcium sulphate and calcium phosphate bone substitutes

    University dissertation from Department of Orthopaedics, Lund University

    Author : Malin K Nilsson; Lunds universitet.; Lund University.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; ortopedi; Kirurgi; Surgery; orthopaedics; traumatology; resorbable; hydroxyapatite; bone substitute; calcium phosphate; injectable; calcium sulphate;

    Abstract : Two formulations of biphasic injectable bone substitutes have been developed for the treatment of bone defects and stabilisation of fragility fractures. The first formulation consists of a calcium sulphate matrix with embedded hydroxyapatite (HA) particles to provide osteoconductivity. READ MORE

  2. 2. Biomimetic Formation of Calcium Phosphate Based Nanomaterials

    University dissertation from Chalmers University of Technology

    Author : Wenxiao He; Chalmers tekniska högskola.; Chalmers University of Technology.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calcium phosphate; lyotropic liquid crystal; bone-like apatite; biomimetic mineralization; self-assembly; nanocomposite; superstructure; amphiphilic peptide;

    Abstract : The intercellular material in bone is a nanocomposite of aligned “hard” inorganics—calcium phosphate (CaP) platelets embedded in the long-range ordered “soft” organic collagen matrix. This elaborate structural arrangement redeems the weaknesses of the individual components (being soft protein or brittle mineral) and gives bone its excellent mechanical properties for the protection and support of our bodies.

  3. 3. Submicron Calcium Phosphate Spheres for Biomedical Applications Synthesis and Use

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tao Qin; Uppsala universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calcium phosphate; spheres; dentinal hypersensitivity; drug release; tooth bleaching;

    Abstract : Calcium phosphate spheres as biomaterials have been attracting attention in recent years. Calcium phosphate occurs naturally in bone, and a hollow structure could be advantageous for drug loading and release. READ MORE

  4. 4. Can Bone Void Fillers Carry Load? Behaviour of Calcium Phosphate Cements Under Different Loading Scenarios

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ingrid Ajaxon; Uppsala universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Calcium phosphate; bone cement; brushite; apatite; monetite; porosity; solvent exchange; degradation; compressive strength; diametral tensile strength; flexural strength; elastic modulus; Poisson’s ratio; fatigue; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : 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. 5. Injectable Calcium Phosphate Bone Substitute In Distal Radial Fractures

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Philippe Kopylov; Lunds universitet.; Lund University.; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Norian SRS; Bone substitute; radius fracture; injectable; calcium phosphate; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Abstract : Fractures of the distal end of the radius are common and occur in many different forms. The long-term results after conservative treatment of fracture of the distal end of the radius in younger adults with special reference to degenerative changes and function are investigated in 76 patients (Paper I).
