  1. 1. On surgical techniques to increase bone density and volume. Studies in the rat and the rabbit

    Författare :Christer Slotte; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; autogeneic bone; bovine bone mineral; calvaria; cortical perforation; guided bone augmentation; maxilla; microangiography; morphometry; rabbit; rat; tibia; titanium implants; vessel topography;

    Sammanfattning : BACKGROUND. Various techniques of surgical intervention have been suggested to promote bone densityand volume; however, the predictability of such techniques is not always sufficiently supported by preclinicalevaluations.AIM. LÄS MER

  2. 2. Survival of onlay bone grafts. A study in the adult rat

    Författare :Monica Gordh; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; polytetrafluoroethylene; artificial; membrane; immunohistochemistry; cortical perforations; bone morphogenetic protein; bone marrow; bone; bone grafts; Odontologi; stomatology; Odontology; skull; tibia;

    Sammanfattning : The aim of this thesis was to study onlay bone grafting in the adult rat to improve graft incorporation and perservation of graft size. In 167 adult isogeneic lewis rats, the size maintenance and bone formation at the graft-host interface of uni- and bicortical onlays positioned in various environments and treatments were investigated.

  3. 3. Tibia stress fractures in athletes : an investigation of possible predisposing factors

    Författare :Ingrid Ekenman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Stress fracture; tibia; overuse injuries; biomechanics; strain; trait characteristics; running; exercise dependency; type A behavior; intrinsic factors; extrinsic factors; local deformation; in vivo; sports; muscle; anatomy.;

    Sammanfattning : This study indicated that posteromedial and anterior tibia stress fractures are two entities with different etiology, pathoanatomy and natural course. In both cases clinical examination and bone scintigram were conclusive for the diagnosis. LÄS MER

  4. 4. Anterior cruciate ligament reconstruction : patellar tendon, Gore-Tex, Kennedy LAD and tibia tunnel ingrowth

    Författare :Olle Muren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Prospective studies; randomized controlled trials; anterior cruciate ligament; treatment outcome; osteoarthritis; knee; prostheses and implant; radiology; reconstructive surgical procedures.;

    Sammanfattning : Anterior cruciate ligament injury can induce permanent functional impairment in the physically active individual. Different methods to repair or replace the tom ligament have been tried and investigated. This thesis investigates three principally different grafts used in ACL reconstruction; autogenous tendon, stent/augmentation and prosthetic. LÄS MER

  5. 5. On methods of evaluation of lower extremity eccentric muscle performance and loading

    Författare :Pär Westblad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Biomechanics; eccentric; electromyography; isokinetic; methods; muscle endurance; pilot projects; reproducibility of results; strain; thigh; tibia.;

    Sammanfattning : This investigation has developed and evaluated methods for measuring eccentric muscle function and loading of the human lower extremity, including isokinetic tests of knee extensor muscle performance and a comprehensive in vivo method for conditions of functional loading. For measurement of knee extensor muscle performance, a protocol of 100 repetitive maximal actions at 90° was applied using a Biodex isokinetic dynamometer. LÄS MER
