Purpose: To assess the feasibility of computed tomography (CT)- and fluoroscopy-guided percutaneous facet screw fixation following anterior lumbar interbody fusion (ALIF) or anterior pseudarthrosis in adults. Materials and Methods: Institutional review board approval and informed consent were obtained for this study. One hundred seven consecutive adult patients (46 men, 61 women; mean age ± standard deviation: 56.3 years ± 12.9) with ALIF (n = 79) or anterior pseudarthrosis (n = 28) were prospectively treated by means of percutaneous facet screw fixation with CT and fluoroscopic guidance. Two 4.0-mm cannulated screws were placed per level to fix facet joints by using either a translaminar facet or transfacet pedicle pathway. Only local anesthesia was used during these procedures. Procedural time was noted for each patient. Postoperative follow-up ranging from 1 year to 3 years was assessed by using Macnab and radiologic criteria. Results: The mean procedure times for a lumbar single-level and a double-level fusion ranged from 15 to 25 minutes and from 40 to 50 minutes, respectively. All the transfacet pedicle (n = 182) and translaminar facet (n = 56) screws were successfully placed in one attempt. Radiographic fusion was observed within the year following posterior fixation in all patients despite one translaminar screw failure. According to the Macnab criteria, the clinical results were classified as excellent in 92 (86%) and good in 15 (14%) of 107 patients at the time of their last follow-up examination. Conclusion : This feasibility study showed that CT- and fluoroscopyguided percutaneous facet screw fixation is a rapid, safe, and effective method. © 2013 RSNA.

: Introduction: In Africa, mortality statistics are not reliable due to the low performance of the death registering systems. Our aim is to implement an efficient system. In this article we make a comparison between the existing system model and the new system that will be set up. Method: UML has been used as the modeling language based on the 2TUP analysis methods. Results: The new system for registering deaths and their causes was conceived and represented through activities, utilization cases and data model diagrams. Discussion: We have developed a tool for death registration taking into account African hospitals characteristics. The progressive deployment of this system at the CHUSS of Bobo-Dioulasso enables users and actors to appropriate it. © 2014 European Federation for Medical Informatics and IOS Press.
