1. 1. Kinematics and fixation of total knee arthroplasties : a clinical, radiographic, scintimetric, and roentgen stereophotogrammetric evaluation

   Författare :Kjell G. Nilsson; Johan Kärrholm; Leif Ryd; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Total knee arthroplasty; tibial component; kinematics; micromotion; loosening; scintimetry; roentgen stereophotogrammetric analysis;

   Sammanfattning : Aseptic loosening of the tibial component is an important cause of failure after total knee arthroplasty. Bone destruction often claimed to be caused by the cement makes the revision difficult. In order to treat younger patients, uncemented fixation has been introduced, but the etiology to loosening is multifactorial and only partly known. LÄS MER

3. 2. Knee joint laxity and kinematics after anterior cruciate ligament rupture : roentgen stereophotogrammetric and clinical evaluation before and after treatment

   Författare :Håkan Jonsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anterior cruciate ligament; Kinematics; Anterior-posterior laxity; Surgery; Roentgen stereophotogrammetric analysis; Muscle strength; Functional tests;

   Sammanfattning : Rupture of the anterior cruciate ligament (ACL) increases anterior-posterior (AP) laxity. The treatment aims to reduce or teach the patient to control this instability. Altered kinematics due to absent ligament function may result in knee arthrosis. This study evaluated the clinical and functional results of reconstructive surgery. LÄS MER

4. 3. Gait and motion analysis of hip arthroplasty. Validity, reliability and longterm results

   Författare :Roland Zügner; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gait analysis; Hip arthroplasty; Kinematics; Radiostereometric analysis; Hip osteoarthritis;

   Sammanfattning : Introduction: Walking is one of the most fundamental activities of daily living in humans, when the hip joints transfer power between the lower extremities and the pelvis. Hip osteoarthritis (OA) will more or less influence this function and is increasing in an ageing population. LÄS MER

5. 4. On lumbar spine stabilization

   Författare :Paul Axelsson; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kirurgi; orthopaedics; traumatology; Surgery; lumbar orthosis.; external pedicular fixation; adjacent segment; intervertebral mobility; Posterolateral lumbar fusion; roentgen stereophotogrammetric analysis; ortopedi; traumatologi;

   Sammanfattning : 71 consecutive posterolateral lumbar fusions without decompression or internal fixation were evaluated with a mean follow-up time of 3.5 (2-7) years. The diagnoses were spondylolysis-olisthesis in 43 cases, degenerative disc disease and/or facet joint arthrosis in 16 cases and pain post laminectomy/ decompression in 12 cases. LÄS MER

7. 5. Chronic lateral instability of the ankle joint : natural course, pathophysiology and steroradiographic evaluation of conservative and surgical treatment

   Författare :Richard Löfvenberg; Per Renström; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ankle-Joint-Instability; Kinematics; Ligament; Osteoarthritis; Orthosis; Proprioception; Radiology; Reaction time; Stereo-Photogrammetry; Subtalar; Surgery;

   Sammanfattning : Chronic lateral instability of the ankle (CLI), defined as frequent sprains and recurrent giving way, difficulty in walking and running on uneven surface, is often connected with pain and swollen ankles. It occurs in 10 to 20 percent after acute ankle injuries. LÄS MER
