  2. 1. On New Implants - The results of five prospective, randomized RSA trials with aspects on phased introduction and continuous migration

    Author : Mats Molt; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; New total knee arthroplasty; TKA; RSA; randomized; prospective; prediction; continuously migrating; safety; stability CR; PS; PF; PA; short stem; tourniquet;

    Abstract : A concern that arises with any change in design or operative technique is whether it affects the long-term implant stability or not. One way to address this is, by measuring early micromotion, to predict the future revision rate. READ MORE

  4. 2. Respiratory Sinus Arrhythmia and Emotion : Effects of pictorial stimuli and state anxiety

    Author : Peter Jönsson; Institutionen för psykologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; state anxiety; emotion; HRV; heart rate variability; RSA; Respiratory sinus arrhythmia; Psykologi;

    Abstract : Respiratory sinus arrhythmia (RSA) refers to heart rate variations due to respiration, which results from parasympathetic nervous system activity mediated via the tenth cranial nerve, the vagus. Thus, the magnitude of RSA is considered as an index of cardiac vagal tone. This thesis explored RSA during emotional responding in healthy women and men. READ MORE

  5. 3. Fixation of the cemented acetabular component in hip arthroplasty

    Author : Gunnar Flivik; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; orthopaedics; reumatologi; Surgery; Skelett; muscle system; rheumatology locomotion; Skeleton; Cement pressurization; Cement penetration; Acetabulum; Cancellous bone; muskelsystem; Total hip arthroplasty; RSA;

    Abstract : In total hip arthroplasty cemented fixation of the acetabular component is a generally successful concept, but the rate of aseptic loosening and consequent revision surgery is still too high. One of the crucial factors for longterm implant survival is the initial fixation and stability. READ MORE

  6. 4. Trochanteric Hip Fractures Clinical Outcomes and the Cut-out Complication

    Author : Alicja J. Bojan; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; trochanteric hip fracture; cut-out; intramedullary fixation; RSA; micromotion;

    Abstract : The established treatment for trochanteric hip fractures is internal fixation, either intramedullary (nail) or extramedullary (plate). Approximately 10% of these patients suffer from mechanical complications, the most frequent one being perforation of the lag screw through the femoral head into the hip joint (cut-out). READ MORE

  7. 5. Kinematics and laxity in the knee, before and after Anterior Cruciate Ligament reconstruction. Evaluation using dynamic and static radiostereometric analysis

    Author : Jonas Isberg; Göteborgs universitet; []
    Keywords : ACL; KT-1000; early reconstruction; early extension; kinematics; laxity; RSA;

    Abstract : Introduction: Whether full active and passive extension training, started immediately after an Anterior Cruciate Ligament (ACL) reconstruction, will increase the post-operative A-P laxity of the knee has been the subject of discussion. For many years, many protocols have included full extension with full weight bearing after an ACL reconstruction. READ MORE
