2. 1. On lumbar spine stabilization

   Author : Paul Axelsson; Lund Ortopedi; []
   Keywords : 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;

   Abstract : 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. READ MORE

4. 2. High-grade spondylolisthesis in young patients : Long-term results of in situ fusion

   Author : Anders Joelson; Per Wretenberg; Karin Frennered; Hans Tropp; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adjacent segment disk degeneration; Fusion in situ; Health-related quality of life; Sagittal balance; Self-image; Spondylolisthesis;

   Abstract : The purpose of this long-term follow-up of 38 of 40 consecutive patients was to evaluate the results of uninstrumented in situ fusion for high-grade isthmic spondylolisthesis three decades after surgery. The mean age at surgery was 14 (range 9-24) years. READ MORE

5. 3. Biomechanical and Clinical Aspects on Fixation Techniques in the Cervical Spine

   Author : Thomas Henriques; Claes Olerud; Sune Larsson; Dieter Grob; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Biomechanics; Atlanto-axial fusion; Distractive flexion injuries; cervical spine; adjacent level motion; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

   Abstract : The present work is analyzing the general biomechanical aspects of fixation techniques in the upper and lower cervical spine along with clinical implications.The in vitro biomechanical properties of five different posterior atlanto-axial fixation techniques are compared. READ MORE

6. 4. Lumbar fusion for chronic low-back pain in isthmic spondylolisthesis

   Author : Per Ekman; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Exercise; Outcome; Long-term; interbody fusion; spinal fusion; lumbar; Adjacent segment degeneration; Isthmic spondylolisthesis; Degenerative disc disease; Chronic low back pain; predictor; prospective; pain drawing; sciatica; psychologic screening; Randomized controlled trial;

   Abstract : Manifestation of isthmic spondylolisthesis (IS), with a prevalence of 5% in the general population, varies from totally asymptomatic to severe disability. Although fusion has positive short-term effects, the long-term outcome of such treatment, as well as possible accelerated degeneration of adjacent segment discs (ASD) and its clinical significance, are unknown.

7. 5. Implementation of a flexible fiber model in a general purpose CFD code

   Author : Jelena Andric; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LPT; OpenFOAM; CFD; flexible fiber;

   Abstract : This work is related to the process of making pulp mats for use in hygienicproducts. One part of that process is the transportation of flexiblecellulose fibers suspended in flowing air. The fibers should be evenlydistributed on the substrate, and it is thus of high importance to avoidthe formation of fiber flocks during the transportation. READ MORE
