A method and apparatus for fixing a ligament in a bone tunnel by cross-pinning the ligament in the bone tunnel. There is a drive axle hole in the center of each support. The display displays an arrangement of symbols including primary symbols and connector symbols, wherein at least some of the primary symbols are separated from each other and at least two primary symbols are connected with one of the connector symbols. The size of the memory is also independent of sub-matrix degree which makes the decoder scalable for large W values. In alternate embodiments, the access controller attempts to resolve the requested operations based on the resource hierarchy information and access list information for the resources in the resource hierarchy information.
