We introduce a method to specify and analyse decentralised dynamic systems; the method is based on the combination of an event-based multi-process system specification approach with a multi-facet analysis approach that considers a reference abstract model and several specific ones derived from the abstract model in order to support facet-wise analysis. The method is illustrated with the modelli...

BACKGROUND Spinal pain is common in all age groups. While the research has focused primarily on incidence and prevalence in younger working adults, there is evidence that spinal pain is one of the most frequent complaints in older persons and is responsible for functional limitations. While facet arthrosis is a common radiographic finding, which has been suggested to be a potential cause of spi...

STUDY DESIGN Facet joint kinematics and capsular ligament strains were evaluated during simulated whiplash of whole cervical spine specimens with muscle force replication. OBJECTIVES To describe facet joint kinematics, including facet joint compression and facet joint sliding, and quantify peak capsular ligament strain during simulated whiplash. SUMMARY OF BACKGROUND DATA Clinical studies h...

The aim of this study was to determine the reliability of magnetic resonance imaging (MRI) in the assessment of facet tropism and facet arthrosis of spondylolisthesis levels in degenerative cervical spondylolisthesis as compared to computed tomography (CT). The discrepancies in the interpretation of CT and MRI data in the evaluation of facet tropism and arthrosis have given rise to questions re...

BACKGROUND The prevalence of persistent low back pain with the involvement of lumbar facet or zygapophysial joints has been described in controlled studies as varying from 15% to 45% based on the criteria of the International Association for the Study of Pain. Therapeutic interventions utilized in managing chronic low back pain of facet joint origin include intraarticular injections, medial bra...

The facet-space approach for accessing document records organized by faceted classifications is described. The interface gives users detailed control over the facet display and it makes use of color to reduce the number of windows which need to be presented. The interface supports searching. A cluster analysis is described for organizing search return lists based on facets distances. The implem...

Abstract Introduction: Although the goal in treating bilateral facet dislocations remains the early realignment of the spine, there is controversy regarding the timing and method of reduction, as well as the optimal approach for stabilisation. A retrospective analysis of prospective collected data from 36 consecutive patients treated for bilateral cervical facet dislocations (BCFD) at the Groot...
