  1. 1. Studies on Cervical Artificial Disc Replacement

    Författare :Catarina Marques; Claes Olerud; Anna MacDowall; Martin Skeppholm; Adrian Elmi Terander; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cervical radiculopathy; artificial disc replacement; Orthopaedics; Ortopedi; Neurokirurgi; Neurosurgery;

    Sammanfattning : Artificial disc replacement (ADR) was developed as an alternative to anterior fusion after decompression for cervical degenerative radiculopathy. By preserving motion, it was expected to prevent acceleration of adjacent segment pathology (ASP) associated with fusion, and lead to better clinical outcomes. LÄS MER

  3. 2. The value of artificial disc replacement in cervical radiculopathy

    Författare :Martin Skeppholm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background; Artificial disc replacement (ADR) is a motion-preserving implant and a further development of existing surgical implants for the treatment of cervical radiculopathy. Theoretically, an artificial disc could decrease stress on adjacent segment and thereby prevent rapid progression of degenerative changes in surrounding segments. LÄS MER

  4. 3. Wear characteristics of materials for artificial hip joints

    Författare :Mohammed Seyed Hoseini Nazari; RISE; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HDPE; UHMWPE; Coating; Tribology; Pin-on-disc; Y-irradiation; Vitamin E; Wear; Implant; Artificial hip joint;

    Sammanfattning : Total hip prostheses have succeeded in significantly improving the quality of life of millions of patients worldwide. Ultra high molecular weight polyethylene (UHMWPE) has been widely and successfully used as a bearing material in orthopaedic prostheses since the 1960s. LÄS MER

  5. 4. Cervical Radiculopathy : Studies on Pain Analysis and Treatment

    Författare :Anna MacDowall; Claes Olerud; Helena Brisby; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cervical radiculopahy; Artificial disc replacement; Orthopaedics; Ortopedi;

    Sammanfattning : Background: Knowledge about how to interpret pain-analyzing tools such as the pain drawing test and the visual analog scale (VAS) in cervical spine patients are sparse; hence, they have never been validated for this subgroup of patients. The method of artificial disc replacement (ADR) has been developed as an alternative treatment to fusion surgery after decompression for cervical degenerative disc disease (DDD) with radiculopathy.

  7. 5. Computed Tomography of Acetabular Cup Wear and Effect of Surface Roughness on Wear and Oxidation of UHMWPE Hip Prostheses

    Författare :Anneli Jedenmalm; Ulf Gedde; André Stark; Karin Jacobson; Nicklas Axén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hip prostheses; Computed Tomography; Surface roughness; UHMWPE; Wear; Coating; Gamma-irradiation; pin-on-disc; hip simulator; Medical engineering; Medicinsk teknik;

    Sammanfattning : Aseptic loosening is the most common complication in total hip replacement (5- 10% at 10 years follow up). The magnitude of the problem is illustrated by the fact that about one million hip prostheses are implanted worldwide each year. LÄS MER
