  1. 1. On percutaneous implants fate and feature

    Författare :Anna Larsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hydroxyapatite; Bone anchored hearing aid; Percutaneous; Abutment; Dermal integration;

    Sammanfattning : Abstract The main objective of this thesis was to investigate skin reactions around percutaneous abutments in the facial and retroauricular regions. Secondary objectives were to investigate the number of lost extraoral implants and their co-morbidity over time, for example complications because of skin reactions due to the skinpenetrating abutment.

  3. 2. Infections associated with percutaneous osseointegrated titanium implants for limb prostheses

    Författare :Jonatan Tillander; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; osteomyelitis; osseointegration; percutaneous implant; titanium; amputation; long-term risk; clinical presentation; biofilm;

    Sammanfattning : Femoral amputation is a devastating event. Percutaneous, bone anchored prosthetic systems reduce problems associated with socket suspended prostheses, but the design is inherently vulnerable to infection. LÄS MER

  4. 3. A Novel Bone Conduction Implant System

    Författare :Hamidreza Taghavi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sound radiation; amplitude modulation; low-power systems.; bone conduction implant; feedback; bone anchored hearing aid; RF power amplifier; gain headroom; implantable transducer; wireless power and data transmission; RF power and data link;

    Sammanfattning : Bone conduction is the process by which an acoustic signal vibrates the skull bones to stimulate the cochlea. Patients with pure conductive hearing loss, mixed hearing loss, and single sided deafness are sometimes poorly rehabilitated by conventional air conduction hearing aids due to for example the functionality losses in the middle ear.

  5. 4. A methodological platform to study molecular biocompatibility of biomaterials. Experimental and clinical studies

    Författare :Maria Lennerås; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegration; titanium; inflammation; cell recruitment; cell adhesion; bone regeneration; bone remodelling; gene expression; immunohistochemistry; histomorphometry; removal torque; ultrastructure; FACS; protein profiling; transfemoral amputation; abutment; percutaneous; bacteria; clinical signs;

    Sammanfattning : The aim of this project was to develop a methodological platform in order to advance our scientific understanding of the mechanisms of osseointegration. Screw-shaped, titanium implants, with different surface properties, were inserted in the rat tibia, or incubated in mono- or co-culture of human monocytes and MSCs. LÄS MER

  7. 5. On the pathogenesis of infections associated with percutaneous osseointegrated orthopaedic implants

    Författare :Magdalena Zaborowska; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; osseointegration; amputation prosthesis; implant-associated infection; biofilm; staphylococci; extracellular vesicles; host defence; cytokines; cell death;

    Sammanfattning : Orthopaedic implants enable the restitution of locomotor function and improve the quality of life of many people. However, biomaterial-associated infection may occur due to the propensity of microorganisms to adhere and colonize implant surfaces. LÄS MER
