Abstract: In order to be able to ascertain the position of the bone in the body without complicated procedures in a process for the preoperative determination of the positioning data of endoprosthetic parts of a central joint relative to the bones forming the central joint, a respective outer articular point is determined by way of movement of the bones about a respective outer joint which is located at the end of the two bones facing away from the central joint. An articular point is determined for each of the two bones in the area of the central joint, and a direction characteristic for each of these bones is determined by way of a straight-line connection of the two articular points obtained in this manner for the two bones. The orientation of the endoprosthetic parts relative to this characteristic direction is then determined. Apparatus for carrying out the process is also provided.

Abstract: A composite package for a group of articles includes a substantially tray-shaped bottom portion having a bottom wall and a plurality of upstanding edge walls which include a front edge wall and a rear edge wall having respective upper edges and which confine the group of articles supported on the bottom wall between themselves. A cover portion is connected to the bottom portion in an assembled condition of the package to cover the bottom portion and the group of articles. The cover portion includes a front wall including a front panel having an opening and two lugs extending along the front panel in a closed position of the front panel. An elongated endless strap is received in the package and loosely surrounds the group of articles in the assembled condition of the package. The upper edges of the front and rear edge walls are provided with holding projections which hold the strap in position on the bottom portion.
